Connectors, Switches and LEDs

Antenna

The transmitter has a gold plated SMA connector. Included is an antenna cut to the correct length for your
transmitter's specific frequency block. You should periodically check that the connector is still securely tightened.

Mix Ratio

This fader controls the ratio between the audio coming directly from the mic and audio coming from the IFB feed
and is enabled when you set
NOTE: If you choose to mix the audio with the IFB return audio you will hear phasing. The reason is the slight
delay in the transmission process before it gets to your headphone. That delayed IFB audio, in concert with
the audio coming directly from the mic, is what causes this phasing, and is totally normal.

Headphone Fader

This fader controls the volume level to the 1/8" headphone jack. When first putting your headphones, be sure to
turn OFF (full counter-clockwise) the headphone volume.

Power Switch

This switch is not as low profile as those on the TRX900 ( /AA). Since this unit is not being used on talent, it
should not be a problem.

Battery

The VPX battery slides in to the battery opening in the bottom of the unit. Be sure to press it in far enough that it
clicks (locks) in place. To remove the battery, press the red edge inward and gently pull the battery out.
Phantom Power Switch & Mic/Line Switch
See Fig 2-3 to get your bearings. Looking inside the opening for the battery, behind the XLR-3F, you will see a red
base and two black switches sticking up from it. The closest switch is for phantom power. Pushing it away from
the bottom is ON. The farthest switch is for Mic/Line-level selection. The closest position is for Line-level.
