The Quantum’s eight analog inputs, ten line-level analog outputs, two stereo headphone outputs, and stereo S/PDIF digital I/O might be all you need today. But your studio is likely to grow in time, and so can your Quantum recording system. Its dual ADAT Optical I/O provides up to 16 more channels of digital I/O at up to 48 kHz (up to 8 channels at 96 kHz).
The Quantum’s ADAT I/O lets you add any ADAT-compatible A/D/A converter but we highly recommend the PreSonus DigiMax DP88 preamp/converter, which seamlessly extends the analog I/O on the Quantum with eight digitally-controlled XMAX preamps, and word clock I/O. The DP88’s mic preamps are fully remote-controllable from UC Surface, Studio One®, and Studio One Remote when connected via ADAT Lightpipe to the Quantum so that they naturally extend your analog inputs both sonically and functionally.
If your studio grows even more, you can stack up to four Quantum interfaces via Thunderbolt. This enables you to create a monster system with up to 96 in and out—more than enough to cover almost any studio’s recording needs.
