Tuning The Amplifier - Subwoofer (s)

1) Subwoofer Signal Routing Switch

Move switch to left position (L+R Inputs) when used with Left and Right subwoofer RCA outputs. Move switch to middle position (L Mono Input) when used with single subwoofer RCA outputs. Move switch to right posi- tion (Signal from Front RCA) when subwoofer signal is to be derived from front and rear channels.

2) GT-RSL

The remote level control (GT-RSL) gives you independent level adjustment of the subwoofer’s output level beyond the standard system volume control. Please refer to the RSL’s manual for installation instruction. The GT-RSL is available separately, please consult your authorized Boston Acoustics dealer. If no GT-RSL is used, switch is set to “Off”.

3) Head Unit

The head unit should have all controls such as bass, treble, balance, and fader set to the flat or centered position. The volume control should be at the minimum setting. If the head unit has any equalization or bass management features such as boost, they should be deactivated at this time. Turn head unit on, and verify that the RED status LED (logo) is illuminated on the amplifier.

4) Volume

With the chosen musical track playing, turn the head unit volume control up until the maximum level of undistorted signal is heard from the speakers. For most head units, this will be at the end of the volume control range.

WARNING! A distorted signal from the head unit sent to the amplifier can cause speaker failure at higher listening levels.
