Heritage Audio 2264JR - PREAMPLIFIER / COMPRESSOR FOR MICROPHONE 500 SERIES

(This text is machine translated) The 2264JR is a 500 Series 2-slot microphone preamp or compressor (not simultaneously), based on the classic diode bridge principle. Its compression characteristics, key components and design are the same as found on the Heritage Audio classic 2264E compressor. A 60dB HA1073 mic preamp has been implemented when compression is not needed. Phantom power is also available. Its audio path is completely discrete in Class A, driven by 2N3055 transistors, balanced by transformer. All controls are mounted on rotary switches for easy recall and high accuracy. A high pass filter has been added on the sidechain to prevent bass signals from driving compression. It has discrete inputs for Compression / Line amp (left input) and mic (right input). The output in both cases is on the left slot output.
