MTX Audio HUB1X4, HUB1X2 Setup, Fault Finding, Features and Specifications

SETUP:

The A-BUS installation should be completed with all power modules connected but not installed into the walls. Follow these steps to give you maximum control flexibility over the volume of your A-BUS system. On the back of the power modules there are trim pots (Left & Right) that fine tune the output level to compensate for the length of the cable run, the efficiency of the speakers and size of the room. There are also situations where you may want to limit the output level in a particular room. With the trim pots adjusted to minimum, the main volume control should be adjusted to maximum level, then with popular music playing the trim pots should be brought up to a point just below the amplifier’s clipping level. (Clipping is the point where the sound starts to distort). When the trim pots are all set to the desired level the installation maybe completed.

FAULT FINDING:

●Most faults occur as a result of incorrect wiring. ●Check all connections carefully.

●Make sure all speakers are wired in phase.

●Disconnect power modules from hub and check operation one by one.

●A short in a line or incorrect wiring will cause the power module to shutdown until the fault is fixed.

●Status indicates the system is active. (LED indicator on infrared models only)

Infrared: Your A-BUS infrared relay system is world standard using the most up-to date technology. However, some infrared codes may present problems. Make sure the infrared emitters are properly placed on the IR receiver of the source components. Infrared systems are more likely to give trouble as a result of too much power. (Try moving the emitter away from the component). Cable boxes and Plasma screens often cause difficulties.
