SET UP AND OPERATION

Follow these directions to set up the transmitter for operation.

1.Plug the power cord into the transmitter's DC INPUT power connector. Plug the other end of the power cord into a wall outlet.

2.Attach the antenna to the ANTENNA OUT BNC connector.

3.Connect line level outputs of an audio source into the audio INPUTS of the transmitter. Use both of the input jacks for a two-channel source. Use either input jack for a mono source. The P4T transmits in MixMode/stereo if both inputs are used, but automatically transmits in mono if only one input is used.

NOTE: All inputs are phantom power protected up to 50 VDC.

4.Select an operating frequency using the Frequency Select Button. Push the button repeatedly until the LED displays the desired chan-

nel. The display flashes. Push and hold the button until the flashing stops to confirm the change (use a 1/4" plug to press the button).

IMPORTANT: Never set more than ONE transmitter to the same operating frequency.

5.Once the P4T transmits audio, observe the input level LEDs. If the LEDs consistently illuminate red, decrease the output level of the audio source until the red LEDs flicker occasionally.

6.Set up the P4R receiver as directed in the P4R user's guide. Make sure that the frequency selected on the receiver matches the frequency selected on the transmitter.
