Power Connections

Tracking down problems that are power related are somewhat easy because the unit either powers up or it doesn’t. If it does not, there are several things to check.

1.Check to make sure you are attached to a functioning live electrical circuit. If the branch circuit is dead check the breaker or there may be a light switch controlling the power to the outlet. If it’s on a switched circuit try to obtain power elsewhere.

2.Ensure that both ends of each power cord are firmly seated in all of the source components.

3.If you’re plugged into power strips, check them for operation as well. Be aware these often have mini- breakers on them and you should check to ensure that power is functioning in EACH outlet.

It is not uncommon for the inexpensive power strips to fail at one plug-in but not the others.

4.There is a power switch located at the rear of the Controller, check to see that it is in the ON or (1) position.

5.There is a fuse beside the power switch at the back of the Controller. Remove the fuse and inspect it to see that it is intact. If you have an ohm meter, test for continuity across the fuse (sometimes they look good,

but they’re really broken near one of the ends). If you are using a power bar they often have mini-breakers on them, and you should check to ensure that all is well. The fuse in the rear of the Unit is a T8AL250v.

Source Unit Connections

Problems in source cabling can often be traced to symptoms where the source cannot be heard in any zone and/ or when the source doesn’t seem to respond to keypad commands.

1.Ensure that the source component’s LINE OUT connections are connected to the Controller’s LINE IN connections for the correct device. These can sometimes be mismatched.

2.Take a look at the source component to ensure that MUTE functions have not accidentally been activated.
