Heritage Audio 2264JR 2-Slot 500-Series Compressor and Mic Pre Mic Preamp HA2264JR
The 2264JR is a 2 slot 500 series Compressor and Microphone Preamplifier.
Its compression features and, key components and schematics are the same found on the Heritage Audio classic 2264E compressor. A fully featured 60dB 1073 mic preamplifier has been implemented when compression is not needed. Phantom power is also available.
Its audio path is fully discrete Class A, 2n3055 driven, transformer balanced. All controls are stepped on rotary switches for easy recall and high precision. A high pass filter has been added on the sidechain to avoid bass signals to ride the compression.
It features discrete inputs for Compression / Line amp (Left slot input) and mic (Right slot input).
Output in both cases is on the Left slot output.
