This very rare used Orban 424A Stereo Gated Compressor/Limiter was made in the USA and comes with an attached Power Cable.

This rare compressor is in very good condition with normal cosmetic wear, has been fully tested, and works great. Please see pictures for details on item condition.

The Orban 424A is a dual mono or stereo linkable gated compressor/limiter and de­esser. It is considered one of the best broadcast & production units available.

The 424A is a VCA compressor that works a little differently than most standard compressors. The input/threshold knob controls the input signal to the compression amplifier. The attack and release times are program dependable which means it’s kind of the same as having the unit in 'auto', but the unit is adjustable within the 'auto' setting. When the attack setting is under 3, the Orban acts like a peak limiter and compressor, but with higher attack settings the 424 A acts considerably slower. There’s also a switch to change the shape of the release curve from linear to exponential (curved, long release).

The ‘gate’ function on the 424 A isn’t really a normal input gate. Its a compressor release 'hold' to prevent pumping of hiss and to smooth out post compression dynamics. The de­esser setting receives its signal pre compression and only compresses frequencies down to 5 K. This function is not only really useful with both lead & background vocals, but for drum cymbals as well. The output trim controls the amount of drive to the VCA compression amplifier. It’s not an output control, per se, but it’s a post­attack and release amp way to increase or decrease amplifier drive.
