Applications
SUB-2RR in a HI-FI system
Connect the SUB-2RR right before your sub-woofer to eliminate hum and buzz problems in your hi-fi, audiophile or home theatre system.
SUB-2RR in your car
The SUB-2RR isolates your car audio receiver system from your sub amp to eliminate nasty sounding ground loops. Locate next to the sub woofer amp for best performance.
