The DUAL LOOP unit is the combination of 2 LOOP units in one single box. 2 bright LEDs, powered with a 9V battery or a power supply (not included), indicate which loop is engaged.

All Huge Audio routers are:

• entirely passive therefore they are completely transparent.
• only using power when a cable is connected to the input jack plug.
• are made to ground the signal when no cable is connected to the input, this will mute the signal on every output of the router so that absolutely no sound comes out of any connected amp even at maximum volume!!!
• only guaranteed to route the signal as per the direction of the arrows printed on the enclosures, warranty does not apply for operation in other directions.
