Sunfire HRS-10, HRS-8, HRS-12 user manual Using the line-level high-pass outputs

Using the line-level high-pass outputs

If you are using a receiver or processor which does not have a Sub/LFE output, you can send its left and right front output into the subwoofer’s Line-Level inputs and then connect the subwoofer’s High-Pass outputs to the inputs of your amplifier.

The subwoofer will play the low frequencies, and your amplifier and front speakers will play the frequency range above the subwoofer’s fixed

(70 Hz) high-pass crossover point.

MAIN OUTPUTS

This is an excellent method if your speakers are small satellites or mini- monitors, and/or your power amplifier is of limited power, such as a tube amp.

TO FRONT SPEAKERS

For the ultimate in computer sound systems, connect the left and right audio output from your computer sound card into the subwoofer inputs. Connect the sub's high-pass outputs to the inputs of your powered speakers. You may need some RCA-to-mini plug adaptors to make the connections. Adjust the sub's volume control to match low-powered speakers. See the note about magnetic fields on page 10.
