SPECIFICATIONS

All measurements taken with an Audio Precision System One. All noise measurements taken with trim at minimum and faders at unity gain with 22 Hz to 22 kHz bandwidth unless otherwise specified. All Tape In & Out measurements made on balanced +4 dBu connectors. (+4 dBu into a line input with minimum trim & faders at unity “0” will yield +4 dBu at any balanced output.)
