Lowpass Crossover Control, RSL Control | Boston Acoustics GT-2125

Tuning The Amplifier - Subwoofer (s)

5) Lowpass Crossover Control

Move the selector switch to “ON” (refer to the diagram on page 5). In this setting, lowpass signal is sent to the speaker outputs. Experiment with the crossover point settings while the subwoofer is active. A higher setting will increase the perceived output, and a lower setting will make the bass response more omnidirectional. 12 or 24dB crossover slopes are available. Depending on your installation and listening preferences, one will work more effectively.

6) Highpass Crossover Control

With some subwoofer applications, it may be necessary to use the highpass crossover to protect the subwoofer from over-excursion. Move the selector switch to “ON” (refer to the diagram on page 5) The highpass should be set to the tuning frequency (vented) or the FS of the subwoofer (sealed or freeair) If you are using a Boston Acoustics® subwoofer, the correct highpass frequency and Q-Tune™settings for that enclosure are outlined in the subwoofer’s owners manual.

7) Q-Tune™Control

Once the highpass crossover point has been determined, use the Q-Tune™control (refer to the diagram on page 5) to increase the bass information centered around the highpass crossover point.

Setting the Q-Tune™control is done in conjunction with setting the levels on the input sensitivity and highpass crossover frequency controls. You may find while setting the Q-Tune™that over-excursion may be detected in the subwoofer (s); lowering the Q-Tune™input sensitivity or raising the highpass crossover point will eliminate this. Minor adjustments to each setting are required to fine-tune the system.

Setting the Q-Tune™is a subtle process. It is recommended that the Q-Tune™setting be left in the 0.7 position and adjusted only after the input sensitivity and highpass crossover ranges are known. Small adjustments to the Q-Tune™setting are all that are required to fine-tune the system.

8) RSL Control

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.
