Boston Acoustics HPS10HO Operation, Adjusting the Crossover Control, Power On/Auto/Standby

Connecting to Electronics Without a Subwoofer Output

If the electronic in your system does not have a subwoofer of LFE output you can connect the HPS units to a preamp output. Use a stereo RCA cable (not included) to connect the preamp outputs to the Left and Right Line Level inputs.

Adjusting the Crossover Control

When using the Line Level inputs (not the LFE input) the subwoofer’s built-in crossover is engaged. As a starting point, set the crossover control on the subwoofer about 10Hz higher than the lower limit of your main speakers’ bass response. Fine -tune the crossover setting by ear for the smoothest blend with your main speakers. The best setting of the crossover control will depend on speaker placement and personal preference

Operation

Power On/Auto/Standby

Plug the subwoofer’s AC cord into a wall outlet. Do not use the outlets on the back of the receiver. Set the power switch to the desired setting.

OFF – The subwoofer is off and will not produce any sound. You may want to turn your subwoofer off if you will not be using it for some time or wish to conserve electricity.

AUTO – The subwoofer will power on whenever a signal is detected. If no signal is detected after several minutes, it will auto- matically enter the Standby mode.

ON – The subwoofer is always on.

An LED indicator between the Power switch and the Polarity switch indicates what mode the subwoofer is in.

OFF – The subwoofer is off

RED – STANDBY (No signal detected, Amp Off )

GREEN – ON (Signal detected, Amp On)

The subwoofer will automatically enter the Standby mode after several minutes when no signal is detected from your system. The subwoofer will then power ON instantly when a signal is detected.

Crossover Control

Adjusts the frequency of the low pass filter for the subwoofer. Note: This control is not active when using the LFE input jack.

Volume Control

Turn the subwoofer Volume control to the 11 o’clock position. If no sound emanates from the subwoofer, check the AC-line cord, Power switch, and input cables. (Are the connectors on the cables making proper contact? Is the AC-line cord connect- ed to a “live” receptacle, is the subwoofer in either the Auto or On position?)

Adjust the subwoofer Volume control until you hear a match between the main speaker and subwoofer. Bass response should not overpower the room but rather be adjusted so there is a natural blend across the entire musical range.
