54. USB Port
This USB connector can be used to connect the AM642D
USB to any modern Windows or Mac-based computer.
Doing so will allow users to get a stereo signal both to
and from the computer. The signal received through this
interface will be sent to the 2T Return bus.
55. Compressor Control and Indicator
This controls the onboard compressor function on mono
channels. Turning this control up towards the 12 o'clock
position will adjust the threshold and ratio of the compressor
at varying degrees. Once you reach the 12 o'clock position,
the control will then adjust the compression settings along
with an onboard expander (or, in other words, a compander).
The LED that accompanies this control will light up when
the compressor is triggered.
