The 2264JR is a 2 slot 500 series Compressor and Microphone Preamplifier, based on the classic diode bridge principle.
Its compression features, key components and design are the same found on the Heritage Audio classic 2264E compressor. A fully featured 60dB HA1073 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).
