The Chandler Limited LTD-2 Mastering Compressor is designed for mixing and mastering applications. The single-space 19" rack mountable unit is handmade and hand wired using original transistors, transformers, and other classic components. The compressor provides you with analog gain reduction metering, and rotary knob controls for 0 to 20 dB gain make up, 10 to -20 dB threshold, 6-position 50 μs to 100 ms attack, and 6-position 50 to 400 ms release settings. The unit also includes a compressor bypass switch that removes the compressor but keeps the Class A amplifier in the circuit for color. A link switch allows you to switch between stereo and surround operation. The unit is powered by the Chandler Limited PSU-1 MKII power supply sold separately.
