The GTA-RSL is an optional accessory that allows the user to remotely adjust the subwoofer level of your Boston GTA amplifier to the main speaker system. This allows greater tuning flexibility from the listening position. This is useful when listening to various musical styles where the amount of bass information may change.
The GTA-RSL uses VCA or Voltage Controlled Amplifier. Within this technique, voltage, not an audio signal is sent to the controller. Changes in the voltage level effect the output level of the subwoofer. This method has the distinct advantage over other designs as the audio signal does not leave the amplifier. Therefore, noise cannot be injected into the system from an external source.

Boston Acoustics GTA-RSL
The Boston Acoustics GTA-RSL is a nice add on for the price. It helped me get my system dialed in very quickly. My amps are hard to get at, so this made it painless.

Great little device, but...
Boston needs to include this little item in their monoblocks purchase since majority of other companies do it anyways. You have to search high and low for this item and luckily sonic has it vs NO OTHER PLACES.
