We have inside of our HP60 headphone amplifier manual, on page 10, the following information:
Stereo Out. The Stereo Out jack carries a line-level copy of the channel’s headphone mix and is commonly used for connecting to additional headphone amplification systems, an additional monitor mixer or even a recording system.
"The Stereo Out level is not affected by the channel’s Level knob."
The information in bold is incorrect. The correct entry is:
"The Stereo output of the individual headphone inputs are fully controlled by the main volume knob of the individual output."
We have notified our writers of the problem and we are sorry for any inconvenience this may cause.
