Lindell Audio 77X-500

While it is designed as a stereo compressor, you can certainly use it for mono sources. The unit offers unlinked stereo operation, which allows you to use the two channels independently for different mono signals if needed.

The 3-step high-pass sidechain filter (Off, 100Hz, 200Hz) prevents the compressor from reacting to low-frequency energy. This is particularly useful on drum busses or full mixes, as it keeps the compressor from 'pumping' or squashing the kick drum and bass too aggressively.

Yes, the 77X-500 utilizes matched FET transistors and vintage-style OPA1731 op-amps to emulate the fast, aggressive character of the classic 1176. It delivers that signature punch and harmonic color, especially when pushed into higher ratios.

Absolutely. The variable mix control is essential for parallel compression, allowing you to blend the compressed signal with your original, uncompressed audio. This lets you retain the natural transients of your source while adding the weight and glue of the compressor.

The 77X-500 is a 500 Series module, so it requires a compatible 500 Series rack or chassis to function. Ensure your rack has sufficient power capacity to handle the module's requirements.

The compressor features a 3-step switched ratio control: 4:1, 12:1, and 100:1. The 100:1 setting is the 'all-buttons-in' mode, which provides the extreme, distorted compression characteristic that the 1176 is famous for.
