Compact 3x8 inch Circuit Board

Ever want to build an audio gizmo with broadcast specs? A custom 4-bus mixer? Digital or pro/consumer +4/-10 interface? 4-out ADA? With flexibility to reconfigure quickly? We did, so we engineered this modular, all-active-circuitry-in-one PCB.

• GET ALL THIS: 2 XLR mic preamps w/phantom power & 3-pos'n gain, M-S encoder, 2 servo-balanced +24dBu line inputs, 4 servo-balanced +24dBu line outs, stereo headphone driver, Tone osc, Slate mic, 2 Utility amps, +/-17vdc reg PS!

• Populate all or just what you need, as AtoD/DtoA I/O, bal./unbal. interface, upgrade consumer gear to balanced professional, miniature 4-bus mixer including (first) two mic preamps and two/stereo lines, etc. Re-configure anytime for quick solution.

• "24 bit" performance: True "impedance balanced" for high CMRR, 3Hz~100kHz response, low THD+N (Analog Devices chips). "Zero Reference" design avoids hum & noise without lifting shield pin 1. Serviceable - socket-mounted ICs.

• Engineering documentation for professional broadcast, recording, film, PA, Web applications. Just mount 3x8 inch PCB in your box with extra connectors, controls, and 24/48vac.
