Description
BAE 1028 Mic Pre/EQ 19-inch Rackmount without PSU is a single-channel rackmount microphone preamp and equalizer based on BAE's 1073-style mic/line preamp circuit with expanded EQ and the 1084-style low-pass filter. BAE's page lists the without-PSU rack version at 19-inch 1RU, while dealer technical data identifies a 19 x 1.75 x 9 in rackmount chassis weighing about 10 lb. The circuit is described by dealers as hand-wired with Carnhill St. Ives transformers, solid-state operation, 0-80 dB gain, selectable 1200/300 ohm mic input impedance, 10 kOhm line input impedance, approximately 150 kOhm DI impedance and 65 ohm output impedance. EQ includes +/-16 dB low shelving at 35/60/110/220 Hz, +/-12 dB or +/-18 dB peaking midrange across 11 frequencies, +/-16 dB high shelving at 10-24 kHz, 18 dB/octave high-pass at 45/70/160/360 Hz and 18 dB/octave low-pass at 6-18 kHz. .
