Are my Eris 3.5s broken?

Sat, 03 Aug 2024 01:34:39 +0000

I have a Windows machine connected to an NI Komplete Audio 2. The NI box is connected to a set of Eris 3.5 monitors. It all worked fine for about thirty minutes playing some quiet audio, then the speakers tossed out a very loud burst of static and are no longer producing sound. The power light is on.

Audio is definitely flowing to the NI Komplete: I can connect a pair of headphones and hear sound; I can plug the outputs from the NI into different speakers and hear sound.

The monitors are definitely not producing audio: A pair of headphones plugged into the Eris headphone jack is silent. I don't think I have anything to test as an aux in, at least not laying around. Cranking the volume all the way does nothing.

I'm not sure what other troubleshooting is left. Did I get a lemon? These monitors are brand new as of yesterday.

Can I connect 2 eris sub bt8 subwoofers to a monitor setup

Sat, 27 Jul 2024 16:34:41 +0000

Is there a set up diagram for using 2 eris sub bt8 with a pair of presonus eris studio 5?

Is there a recommended fix for the Eris E8 hum?

Sun, 30 Jun 2024 22:27:44 +0000

I've owned a pair of Eris E8 for several years and enjoy their sound. Having made music in a London flat during this period of use I've recently relocated to a studio space that is not polluted by fridge, street and general background city sounds.

I noticed a hum since i first used them but only when very close (ear next to woofer), in a sealed studio it's clear the monitors emit a constant hum and high frequency noise, standalone (unplugged from any audio source).
I've tried the monitors in other plug sockets away from the studio, different power cables etc, the hum is ever present.

There are many unanswered comments and reviews online (both on this site and elsewhere) regarding this hum on the E8 that seem identical to what i've experienced since purchasing. But no clear response or answers that i've seen.

I would really appreciate understanding if this hum/noise known to affect some or all units and if there are any known resolutions to this issue. I suspect my guarantee is long gone so any insight into current repair options (if any) with an authorised engineer in the UK would be really helpful. I want to keep using them!

Change threshold for standby feature on Tremblor T8?

Wed, 19 Jun 2024 01:32:47 +0000

Hi there,

I have an ongoing issue where signal going through the Tremblor isn't enough to trigger the standby feature. So music is constantly cut-off, which requires the volume be turned-up until the standby is triggered.

But this...

Creates a bust of incredibly loud music which is blood-boiling
Pops the Eris monitors connected to it which is incredibly annoying

The system sounds great but this standby feature is so mind-numbing that I'm going to physically remove it if there isn't a way to change the threshold on the incoming signal. If speakers sleep while music is playing, what's the point? Truly.

Here's hoping there's a way to fix it without physically butchering it.

Namaste.

E5s simultaneously overheated, will not turn back on a day later. Can this be fixed?

Sat, 01 Jun 2024 00:24:37 +0000

Hey there, my Eris E5s got extremely hot when I was playing them, then shut off altogether. I've tried replacing the fuses (although the old ones were intact), and have opened them up and there is no visible damage to the inside of the speakers. I've also tried different power cords to no avail, and am wondering what the next steps might be, as I have no warranty on them.

Why am I only getting sound out of the tweeter on my left speaker model type Eris E3.5BT?

Thu, 23 May 2024 13:13:44 +0000

Bluetooth connection. Right speaker sounds fine. No left bass, only tweeter

Presonus Eris 3.5 - Loud popping sound when turning off!!!!!!

Sat, 04 May 2024 09:28:28 +0000

I'm so tired of this! I don't know how to solve it! I've read hundreds of threads on reddit, I've read dozens of threads here in the presonus answers and I haven't found a single concrete answer on how to fix it!

Every time I go to bed I turn off my laptop, then turn off my studio monitors and they make a loud cracking/popping noise, my wife thinks I'm throwing something on the table...
These are my second monitors, I've tried everything, the order of switching off, different cables, I've tried different power supply, even just when I plug them in and out (without an audio source) they still make a loud crackling noise when they are turned off!

Presonus will you finally answer how to fix this? What did I pay money for?

I uploaded the video to YouTube

I want to buy a longer power lead for my eris 3.5BT, will any figure 8 power lead be okay?

Mon, 22 Apr 2024 14:01:27 +0000

The speaker at the back says 60W next to the power in. Most cables say 75W or 120W. Please advise so I can buy a much longer power cord

Thank you

Audio output on my Eris 3.5 only through headphone jack ?

Why does the audio and blue light fade in and out when bass hits?

Wed, 13 Mar 2024 06:17:22 +0000

The sound of my Eris sub eight subwoofer studio monitors fades in and out along with the blue light when the bass hits. And the volume isn’t very loud at all. In fact its pretty low. But it sounds like a wobble sound

E4.5 too quiet

Sat, 09 Mar 2024 21:35:40 +0000

New e4.5s plugged into either pc using or trs cables into audio interface has the same problem of needing the volume at 100% just to start to hear it. I've tried different cables to no avail.

Does the bluetooth connection to Eris Sub8BT also drive the wired outputs to the bookshelf speakers?

Thu, 07 Mar 2024 16:44:00 +0000

The Sub8 supports pass-thru with high-pass filtering which is great. A common installation connects the line source (my PC) to the Sub8's inputs and then the Sub8's outputs drive a pair of amplified mid/high frequency speakers. By using the Sub8's high pass filter and low frequency cut-off, one can ensure the subwoofer and the other speakers are each handling the frequencies they handle best.

What happens if I connect the Sub8 over bluetooth when I'm still wiring the other speakers to the Sub8's outputs? Does the Sub8 act the same way, sending the low frequency component of the audio received via Bluetooth to itself while sending the mid/high frequency components of that Bluetooth audio to the other, wired, speakers?

That (to me) would be much preferred to connecting all three speakers over bluetooth. Passing the bluetooth audio through the Sub8 ensures it can high pass filter that audio before passing it along to the other speakers. You don't get that if all the speakers connect directly to the source over bluetooth.

Thumping on my Eris 3.5 when plugging in audio?

Have you fixed the power problem of e3.5 bt, or got it again?

Fri, 16 Feb 2024 03:40:21 +0000

Your hairdryer therapy worked for me for a while, but the power has gone after the amp got cooled down. I touched the 100uF capacitor and the amp worked when it was hot. As it gets cooled down it makes some white noise and finally is gone. How's your e3.5 doing?

Speakers cutting in and out - noise, crackling, connected to DELL Monitor

Thu, 08 Feb 2024 07:41:47 +0000

Hello everyone,

I received my Eris Studio 4 Speakers yesterday and wanted to test them immediately.
My setup was as follows:
- 2 x Presonus Eris Studio 4

- 1 x Cable to connect both speaker to my DELL U2723qe Monitor Output (https://www.thomann.de/de/the_sssnake_ypk2030.htm)
- MacBook Pro with the M1 Pro Chip

- USB-C cable to connect my macbook pro to my dell monitor

When I turn the speakers on they start hissing and crackling and when I play music, the music cuts in and out (like a frequency with with 2 hz or something similar).
When I Connect the speakers with the cable directly to my macbook, it also crackles, but it does not cut in and out.
When I turn off the DELL Monitor and connect the speakers to my macbook, they work perfectly.

Does anybody know what the reason for this problem might be?
Is it the cable? Do I need to use the unbalanced port instead of the balanced?
And why does my external Display destroys the speaker signal but not my macbook?
I need to work with an external monitor (DELL) so not using a monitor is not an option.

I hope you can help me out, feel free to ask any questions, I try my best to answer them (I am not an audio or computer expert).

How is PreSonus going to address the high noise floor in Eris studio monitors?

Sat, 20 Jan 2024 18:55:21 +0000

I purchased 1st gen eris 4.5 monitors and encountered a very high noise floor when the monitors are turned on. The noise/hiss occurs when only the power cable is connected and no inputs are connected. I flip the switch and then a few seconds later the power amps kicks on and the noise starts from both the tweeter and woofer. Before offering any suggestions, I have tried the following:

- disconnecting everything except the power cable

- plugging into every other outlet in the apartment, including multiple different power strips AND the grounded outlets in the kitchen and bathroom

- Wrapping the entire monitor in several layers of aluminum foil to eliminate any EMI/RF interference

- adjusting all gain knobs and frequency knobs. The noise occurs regardless of the position of any knob (ex. gain knob fully 0% and at 100%)

This noise can be heard whenever the power amplifier in the primary speaker kicks on. It can be heard from 6ft away. I understand all active monitors have some noise when listening very close to the speakers, but the level of noise is extremely audible from several feet away and can be heard when a source is plugged in and music is playing. The volume and character of the noise does not change with input source, input gain, monitor gain, position in the house, amount of additional shielding, etc.

Tech support sent me a replacement pair. Same issue. They then sent me the eris 4.5BT 2nd generation model, and the same issue occurs. Unbearable level of noise/hiss regardless of the set up. Note: this is not in some super quiet studio or anechoic chamber. This is in my apartment next to a busy road with the constant sound of cars going by, and this hiss is still audible from 6ft away.

What is PreSonus going to do to address this issue in the eris 4.5s?

I want to repair my studio monitor Eric 3.5. Please can anyone assist, where I can repair it in Pune Maharashtra.

HOW ONE DOES ONE CONNECT AN ERIS 5BT GEN 2 AND AN ERIS SUB 8BT CONCURRENTLY ON A PC UNDER WINDOWS 11

Mon, 18 Dec 2023 18:25:11 +0000

As stated, I would like to know how does one connect an Eris 5BT Gen 2 AND an Eris Sub 8BT concurrently on a PC under Windows 11? I just purchased a pair of new Eris 5BT Gen 2 Monitors AND an Eris Sub 8BT from Amazon and received them. I am attempting to install them on my system through a Bluetooth connection. I have been working on this for a couple hours, and I can find NO way to make both the Monitors AND the sub work at the same time. I can make them both output sound connected by Bluetooth separately but NOT at the same time in a 2.1 fashion. Windows appears to only allow output by Bluetooth to only one Bluetooth speaker. Not both. Can both speakers connect to one another by Bluetooth? There IS NOT a current "User Manual" on the PreSonus website for the newest models of the Eris 5BT Gen 2 or the Eris Sub 8BT.... If both the monitors and the sub cannot connect to the computer and function at the same time through Bluetooth, what is the point of having both of them Bluetooth? Did I waste money buying the newer speakers?

PreSonus Sub Volume Control

Sat, 09 Dec 2023 18:09:20 +0000

Audio newb here. I have a pair of Presonus Eris E3s paired with a Eris Sub 8BT hooked up to my PC, problem is I don't know how to set them up so the volume control also increases and decreases the sub volume. The only way I currently have to adjust the volume is with the gain control on the back of the sub.

I don't currently have a soundcard, using audio with Realtek audio drivers. The E3s are connected to the sub and the sub connects to the PC via Bluetooth.

pin1=GND (Ground)

pin2=HOT (+)

pin3=COLD (–)

Why is the woofer in my presonus eris 5 not working? Just the tweeter

Eris 3.5 not powering up

Fri, 03 Nov 2023 07:34:40 +0000

I have owned my Eris 3.5s for over 2 years without any issues. Today I turned my Surge Protected power strip off at the wall, which includes many varying electronics, and turned it back on a few hours later and all my electronics turned back on as usual, other than my Eris 3.5s.

The blue LED indicator is off, and the monitors have no power and produce no sound, nor buzzing/noise. This is my first ever issue with my Eris 3.5s and I'd love an easy fix to solve all of this.

I have already tried using a different power cable, plugging into a different power strip, plugging directly into the mains, and plugging into the mains in a different room.

I use them in my work as a sound designer, so I am unable to work.

Any suggestions are appreciated.

advice on audio monitors and subwoofers

Wed, 25 Oct 2023 14:05:05 +0000

Hi, I would like some advice from you if possible.
I have an Eris 8 subwoofer,
I'm also considering buying a pair of monitors to go with it.
for home studio listening, therefore flat and linear. Do you recommend the Eris E4.5 or the Eris Studio 4 more?
which of these two pairs is best matched also based on their power and the power of the subwoofer?
I await your reply, thank you.

Speaker is making constant sound that sounds like a muted gun constantly being shot when i turn it on

Mon, 25 Sep 2023 12:15:51 +0000

(ERIS E3.5)

Had a power cut this morning and my speakers were own, power came back on and since then my speakers sounds like a gun being shot constantly for 2mins then it will die down to as constant buzz but its louder than any of the audio coming from my pc. Has something broke inside it and need repaired? Or could it be something that just needs tightened.

I also dont know if this connected to it but for 6months now and time i do turn off my monitors it makes a louding popping sound just once but since they issues im having happened its multiple loud pops.

Any advice would be greatly appreciated as customer support refuse to let me even know the general thing wrong so that i could fix it since they refuse to repair things unless they are still under warranty

Recommended noise free USB psu for Presonus MicroStation BT

Thu, 24 Aug 2023 12:11:33 +0000

My Subwoofer serial is being denied as an Invalid Serial

Wed, 16 Aug 2023 00:40:23 +0000

I just recently purchased a T10 brand new with an authorized distributor in my country, I even decided to register my 8 y/o Pre Sonus Eris5 (which I purchased at the same store) and those serials went thru without problems. I have a picture of both electronic invoices of these purchases, taken from the Distributor's PC. T10 was purchased on 08/11/23 and Eris's purchase date was on 01/05/16. I did verify letter by letter, number by number, Serial in the back of the unit is the same as the Registration paperwork included inside the box. Really odd.

High Filter on Temblor T10

Fri, 21 Jul 2023 02:04:08 +0000

I have Eris 4.5 and T1 with HPF on and Low filter set at about 80hz.

Why does Eris woofer start vibrating at around 35-40hz? I thought the midrange monitors would not receive any signal less than 80hz if HPF on T1 was on. Could there be a problem with T1? or is this normal with crossover slope?

Thanks.

Eris E3.5 PreSonus Bluetooth will not appear in list of devices on Windows 11

Wed, 05 Jul 2023 22:07:05 +0000

I have restated devices, updated Bluetooth drivers, ran troubleshooters, made sure the speakers were not paired with more than 2 devices, followed all of the recommendations on Fix Bluetooth problems in Windows website, and I still cannot get the speakers to pair with my computer. I made sure the speakers were in pairing mode when attempting to pair. The PC is ibuypower, purchased in Summer 2022 from Best Buy. The speakers show up on my phone. The speakers sit 6 feet away from my computer. When the speakers are wired into the computer they work. My computer has no issue pairing with other devices. My partner is tech savvy and has tried all these + plus other solutions I may have not tried and he can't get it to work either.

I purposefully bought these speakers to use for my piano + my pc since it has Bluetooth capability. What would make this not work?

E3.5BT bluetooth interferes with other Bluetooth devices

Tue, 16 May 2023 13:31:44 +0000

I've discovered that the Bluetooth functionality on the E3.5 BT interferes with other Bluetooth devices, in my case the Bluetooth receiver on my Windows PC motherboard and/or my wireless Xbox controller, causing the controller to behave weirdly and delayed. When I turn off the speakers, the controller works fine. Is there a way to turn off Bluetooth on the E3.5 BT?

Eris Sub 8 power unit improvements

Tue, 21 Feb 2023 12:19:13 +0000

I have some suggestions or recommendation for future builds of Eris Sub 8 and it's series.

First of all, I noticed that the main transformer causing a relatively big burmming noise. This noise can be detected when everything is quiet, but it was loud enough to be annoying even if my main computer is running. I disassembled the sub and noticed that the screws of transformer were loose. I don't know if it was caused by handling issue during transportation or manufacturing issue, but gluing the screws could fix / prevent this issue easily and cost effectively. I don't know if this was a unique situation or others experienced with the same issue, but I gently tighten the screws and the brumming noise gone.

The second problem I found is a switch on/off transient issue. This could be easily fixed by applying a small, 4.7 - 22nF / 600V capacitor + 500KOhm resistor in parallel of the main switch (between the two contacts). This used in many high-end systems to avoid switch-on/off transients.

The same must be added to ERIS studio monitors as well!

Future improvement could be a slow-switching on (so-called cold-start) circuit which could help reduce the stress to transformer and the whole power line. Some times, my UPS detecting that I'm switching it on...

Last recommendation to add a power outlet to Eris Sub and only switching on the SUB (of course it could be selectable) if the power outlet having a power consumer. Couple of Euros device can do this, but would be awesome to have this feature. Especially when users having Eris 3.5, 4, 5 monitors...

Interference issue, PC + Eris E3.5 = no noise, PC + Sub8 + E3.5 = noise from mouse?

Mon, 20 Feb 2023 23:34:41 +0000

Hunting some noise gremlins in my setup.

PC USB audo card (soundblaster g1) via 3.5mm to RCA to Eris E3.5 = no problem, very clean

PC USB audio card (soundblaster g1) via 3.5mm to Sub8 to Eris E3.5 via RCA cable = electrical noise made worse by mouse movement?

Tried a few different cables, isolating power and input device cables, even ferrite cores (desperation)... no difference. USB bus/motherboard to blame? Maybe the RCA cable? Switch to TRS between Sub and E3.5s?

How can i connect eris 3.5bt to the sub8 when i hear bluetooth?
