More Setup, calibrating and integration
If you are running a pair of SVS subwoofers (Fig. 2), you will need to use an inexpensive “Y” cable adapter (d.) From the “Y” cable you can run a stan- dard 75 Ohm RCA signal cable (e.) to each sub, thus “splitting” the Low Fre- quency Effects (LFE) and other bass from your receiver, and effectively feed- ing both subwoofers with the same signal (when phase is properly adjusted, achieving a significant 6dB of added “headroom” versus only one sub). .
NOTES: Determine if you want “ON” (always on) or “AUTO ON” which turns your sub on only when a bass signal is present. High
power amp designs can require five minutes of “OFF” time before sub will resume “ON” status again.

“Calibration” isn’t only for technically minded sound enthusiasts. It is ’s criti- cal to a proper configuration of your home audio system. Fortunately, adjust- ing channel balance (essentially all “calibration” amounts to) is simple to do.
The first requirement is to ensure your AVR is ready. Thus we recommend you consult your AVR manual to review the choices you have regarding setup. Generally, this requires your receiver’s test tones play back at the same volume from each of your system’s speakers. Of course this can in- clude speakers at left, center, right, left surround and right surround plus the subwoofer itself.
Some things to check as you get ready to calibrate:
∙Are your speakers set correct to the correct “size”? Your
AVR should allow you to your speakers be set to “Small” or “Large”. Selecting the size accordingly will ensure bass goes to most appropriate speakers, and use the subwoofer correctly too.
“Small” is nearly always the best configuration with a good sub- woofer and all but the largest speakers.
