REMOTE SUBWOOFER LEVEL (RSL)
INTRODUCTION
The GT-RSL is an optional accessory that allows the user to remotely adjust the
subwoofer level of your Boston GT
™
amplifier relative 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 GT-RSL uses a VCA or Voltage Controlled Amplifier. With 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.
Note: This accessory is only compatible with the GT-50, GT-42, GT-40, GT-28, and
GT-24.
