BAE 1032 - Mic Pre/EQ Module
MPN #1032MOD
The BAE 1032 4-band Mic/Line preamp Module was inspired by the frequencies of the classic 1081. Hand wired, all discrete using modular cards and Class A transformer-coupled.
It uses the same high quality components and manufacturing techniques used in other BAE modules featuring the same Class A transformer-coupled circuits and same modular cards for long-term serviceability.
Along with the passive inductor high-pass filter, the 4-band equalizer provides greater coverage. The high-mid and low-mid frequencies overlap for flexibility in correcting problem frequencies. The 1032 also provides a more comprehensive high frequency shelf up to 24kHz for extended high frequency correction without compromising the midrange.
Many people loved the EQ portion of the 1081 but the amplifier was class A/B. Our clients told us that they prefer the class A output and so we now have a 1081 inspired equalizer with a 1073 preamp.
