Boss RCL-10 Micro Rack Series Compressor Limiter, USED

This item has been tested and powers up with each individual effect working as intended however there does seem to be intermittent output issue.

In its normal application a compressor is a PROCESSOR rather than an EFFECT, and it isn't intended to be heard in the same way that an effect is. Rather it is required to disappear - to be as transparent as possible.

Unfortunately, as it goes about its business, rapidly altering its gain inversely to the change in level at its output, unpleasant pumping sounds are often incurred. This is where the system's background noise is heard to whoosh up and down in volume, as the compressor increases and decreases its gain to maintain a constant output level for a wavering input level. As the input signal gets weaker, so the compressor progressively cranks its gain up, thereby giving maximum volume when there's nothing but background noise present: not the perfect situation. Hence, combination compressor/gate devices such as the RCL-10, are becoming increasingly common at all levels and really are an indispensable facility to have. With an expander/gate in the system, you are able to compensate for this by juggling the two threshold levels so that the expander/gate closes down on the noise but lets the actual signal through.

For a small unit, the RCL-10 offers a lot of control, and unlike any of the four other models, this one features an input overload indication LED.

On the compressor/expander section, threshold, compression/expansion ratio, attack and release are all continuously adjustable, as are the threshold and decay time on the noise gate. This makes the RCL-10 a very flexible unit considering its price. The compressor's attack time is adjustable from 0.2ms up to 2secs which should take care of most things.

The unit's small size means that there is only a limited amount of space for controls etc. Even so, there could perhaps have been a few LED's included as a basic indication of how much compression is taking place. As it is there's but the one LED to indicate the crossing of the threshold.
