Audio Injector XLR preamplifier for The AI-ABS v1 Standard

Signal relay muting, balanced low noise design. DC (0 Hz) to 96 kHz bandwidth. Impliments a third order low pass output filter. Implements the AI-ABS v1 analogue standard - will interface any soundcard which implements this standard. 13 dB output gain, -12.8 dB input gain. Designed to run output lines around +- 10 V. Example sound card matches : Audio Injector Isolated and Pro. sound cards. Features and specifications Balanced preamplifier with XLR connectors and headers pre-assembled Audio Injector analogue breakout standard headers (suits any soundcard which implements the AI-ABS v1 standard) Professional level signals Relays as muting circuits - ensuring popless & silent reboots DC coupled - no AC coupling caps 0 Hz to 96k Hz analogue bandwidth Output gain : 13 dB Input gain : -12.8 dB XLR preamplifier designed FS peak to peak output voltage : around 20.4 V (about 19.4 dBu) Very low harmonic distortion - we use film caps. in the signal path, we also don't use AC coupling caps. Very low noise floor, due to the balanced design and output buffer circuitry.
