About Heritage Audio 2264JR

Where professional audio recording and production are concerned, the Heritage Audio 500 Series 2264JR Compressor and Microphone Preamplifier stands out as a durable, high-quality, and reliable solution. This versatile device is a 2-slot 500 series unit that seamlessly combines the functions of a compressor, limiter, and preamplifier, making it an ideal choice for musicians, producers, and engineers who demand excellence in their audio equipment.

The 2264JR mirrors the key components and schematics found in the classic Heritage Audio 2264E compressor, ensuring the same level of superior performance. When compression isn't required, a fully-featured 60dB 1073 microphone preamplifier is at your disposal, complete with phantom power for condenser microphones.

This unit boasts a fully discrete Class A audio path, driven by 2n3055 and balanced by a transformer, ensuring pristine audio quality. All controls are stepped on rotary switches, offering high precision and easy recall of your preferred settings.

To enhance its functionality, the 2264JR includes a high-pass filter on the sidechain, designed to prevent bass signals from dominating the compression. It also features discrete inputs for Compression/Line amp (Left slot input) and microphone (Right slot input), with the output in both cases on the Left slot output.

In essence, the Heritage Audio 500 Series 2264JR Compressor and Microphone Preamplifier is a testament to the brand's commitment to producing versatile, reliable, and high-quality audio equipment.
