[. . . ] This eliminates unwanted low-frequency energy so that all the power from the HRS120 amplifier is dedicated to useful low frequencies. THX = 0dB For Surround Sound Mixing: Push this switch in to add 10 dB of gain to the subwoofer signal. This allows you to record the LFE channel at ­10 dB relative to the other channels, as specified by AC-3 encoding standards. For Playback: Push this switch in to add 10 dB of gain to the subwoofer signal. This is useful for home theater applications where the LFE channel requires additional gain to balance with the other channels in the surround sound system. INPUT SENSITIVITY INPUT SENSITIVITY FILTER BYPASS OFF NORMAL FILTER BYPASS FILTER IN FULL RANGE THX = FULL RANGE This switch bypasses the built-in low-pass filters (variable and elliptical). Push this switch in when connecting an LFE or subwoofer output signal from a mixer or preamp to the LEFT(MONO) and/or RIGHT inputs, to avoid "double-filtering" the low-frequency signal. Note that the LEFT(MONO) and RIGHT OUTputs are still high-pass filtered and affected by the CROSSOVER controls. THX = NORMAL The HRS120 expects a line-level signal at its input connectors. · The sensitivity is 89 dB SPL at one meter with a 100mV (­17. 8 dBu) input signal, with the INPUT SENSITIVITY control set to its NORMAL position (in other words, wide open). · The HRS120 is designed to operate with a nominal +4 dBu signal when the INPUT SENSITIVITY control is in the NORMAL position. · Refer to the QUICK START section on page 4 for the level-setting procedure. 8 POLARITY 0° 180° POLARITY THX = 0° This switch reverses the polarity of the signal going to the subwoofer amplifier by 180º. It has no effect on the signal at the LEFT and RIGHT OUT or the MASTER OUT. Listen to the overall blend of the subwoofer with the rest of the system, and select the switch position that gives you the best sound.

Connect the full-range line-level signal from the mixer or preamplifier to one of these input jacks. The connectors are wired as follows (per the AES/IEC standard): XLR RCA Hot (+) Pin 2 Tip Cold (­) Pin 3 -- Shield (Ground) Pin 1 Shield If connecting a single subwoofer or LFE output to the HRS120, use the LEFT (MONO) input with the FILTER BYPASS switch pushed in. 0dB +10dB POLARITY NORMAL SUB SAT 80Hz 0° 180° OFF NORMAL CROSSOVER CONTROLS POLARITY LEFT SUB SAT IN (MONO) OUT 80Hz 55Hz 110Hz CROSSOVER L L IN OUT R LEFT AND RIGHT OUTPUTS Balanced XLR male and unbalanced RCA female connectors are provided for the line-level left and right high-pass outputs. Connect these to the inputs of the main speakers (if they are powered speakers) or to the inputs of the amplifier powering the main speakers. The low-pass output from the crossover goes to the internal power amplifier in the HRS120, while the high-pass output goes to these output jacks.

The crossover frequency can be adjusted from 55Hz to 110Hz. 9 Frequencies below the crossover frequency are sent to the subwoofer, and frequencies above the crossover frequency are sent to the LEFT and RIGHT OUTputs, which are connected to the main/satellite speakers. Set the crossover frequency to the lowest frequency response rating of the main/satellite speakers. across the tip/sleeve when the internal relay is open, and a maximum 1 amp of current when the relay is closed. CAUTION: There is an internal 1A fuse to protect the REMOTE INDICATOR circuit. Exceeding 1A of current may blow the internal 1A fuse. MASTER OUT/SLAVE IN Balanced XLR and unbalanced RCA female connectors are provided for the MASTER OUT/ SLAVE INputs. Use these for daisy-chaining two HRS120s by connecting the MASTER OUT jack from the first subwoofer to the SLAVE IN jack on the second subwoofer (see note below). The SLAVE IN bypasses all filtering, but is affected by the POLARITY and INPUT SENSITIVITY settings. The MASTER OUT is post-filtering (variable and elliptical crossover, subsonic filter, and LFE gain) and pre- POLARITY and INPUT SENSITIVITY.
