Page 8: Tuning The Amplifier - Front And Rear Speakers
Tuning The Amplifier - Front and Rear Speakers 1) Music The material chosen for system tuning must be both clear in recording quality and dynamic in amplitude. Many audiophile “test” discs have musical tracks with both of these characteristics and should be used. 2) Front, Rear, and Subwoofer Input Sensitivity Controls Turn controls all the way counterclockwise (minimum position). -

Tuning The Amplifier - Front and Rear Speakers 7) Input Sensitivity Control Starting with the front channels, slowly rotate the control clockwise (refer to the diagram on page 5) until maxi- mum undistorted playing level is heard from the speakers. Listen closely for bottoming from the speakers. If detect- ed, rotate the input sensitivity control counterclockwise until it is eliminated. -
Page 10: Tuning The Amplifier - Subwoofer (S)
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”. -
Page 11: Subwoofer Input Sensitivity Control
Tuning The Amplifier - Subwoofer (s) 5) Subwoofer Input Sensitivity Control Turn control (refer to the diagram on page 5) all the way counterclockwise (minimum position). In this position, the amplifier will be less sensitive to the input signal from the head unit. Slowly rotate this control clockwise until maximum undistorted playing level is heard from the subwoofer(s). -
