9. Plug in only the RCA cables for the amp connected to the subwoofer
(usually Zone 4). Set the low pass crossover on the subwoofer amp in the
60- 80 Hz range. Set the Master level control on the WS-220 BT to about
¾ of max. Set the Zone level control to about ¾ max. Slowly turn the
amp gain up until subwoofer distortion is heard. Slowly back off the amp
gain from that point until the subwoofer is playing as loud as possible
without distortion. This is the optimal setting.
10. Turn the source unit back down and plug in all RCA cables to all amps.
Do a final check on all zones and all channels. All gains should now be
set to “unity” meaning they are at the same level and matched on all
zones.
