Notes

•Do not use for switching power amp speaker outs and other such powerful signals, as this may damage the unit.

•To prevent malfunction and/or damage to speakers or other devices, always turn down the volume on all devices, and turn off the power on all devices before making any connections.

Operation

Depress the switch to toggle between Channel A and Channel B. You can confirm the currently selected channel by checking to see whether Indicator A (red) or B (yellow) is lit.

Indicator B

*The IN/OUT jack doubles as the power switch. Unplug the cable from the jack after use to extend battery life.

Changing the Batteries

When an indicator (A or B) loses its brightness, it means that the batteries are nearly dead. Remove the (two) screws from the underside and open the cover. Then, replace the batteries (size AAA) with two fresh batteries. Do not mix fresh batteries with used ones.
