STEP 5: CONNECT THE POWER SUPPLY

The T4 transmitter is powered by a wall mounted transformer supplying 24 VAC. Plug the

transformer into a suitable 120 VAC outlet and connect the attached cable to the transmitter.

The cable connector has a retaining catch which must be installed toward the top of the

transmitter as shown on the T4’s back panel. Though no damage will result, the T4 will not

operate if you install the cable upside down.

Neither the T4, nor its power supply, are equipped with a power switch. Because there is no

“wear out” mechanism and power consumption is minimal, continuous operation is not a

problem. If you want to control power to the transmitter, connect the power transformer to a

switched 120 VAC supply or a master switched outlet for the entire sound system.

STEP 6: ADJUST THE AUDIO INPUT CONTROL

Play a compact disc or other quality audio source through the complete sound system at a

level that is typical of normal operation. Adjust the Audio Input control so that the Level

Indicator

0 dB

LED generally lights and the

+6 dB

LED lights occasionally.
