Product Overview

Audio Input Socket

The specific socket type may vary by unit. The following connectors are available:

Small 6-Pin LEMO™connector (pictured above)

Large 6-Pin LEMO™connector

Mini 5-pin BM5 Connector (for TA5F cable)

The 6-Pin LEMO™connectors allow for the microphone-input cable to be

connected by a push-pull action. The Mini 5-pin BM5 Connector allows for the

microphone-input cable to be connected by a push-latch into TA5F. For more

information on pin details please see the Connection details in the Further

Technical information section of this manual.

LED Indicators

Modulation Level and Battery Status

The three LEDs show the modulation level of the transmitted signal and the

battery status. When the battery level is sufficient the light is green and when the

battery is low the LED turns red, as an indicator to change the battery as soon as

convenient. The modulation level LEDs (-10 and 0dB) indicate the audio level, for

straightforward adjustment of the transmitter gain and this enables repeatable

levels to be set with ease.

Antenna Socket

The detachable antenna can be connected into this miniature 50SMA coaxial

socket by a simple screw-on action.

Using the AWT-1

Tuning the transmitter

There are two methods available for tuning the transmitter allowing both complete

flexibility and convenience. These are tuning by Frequency or by numbered UHF

TV Channel with pre-coordinated Sub-Channels.

Tuning By Frequency

By default the Frequency menu is the first menu that appears upon turning ON

the unit. On the Frequency menu the currently used frequency for transmission is

displayed on the screen in MHz.

1. To tune, press the SET-PWR button to start the frequency select mode.

In this mode the displayed frequency flashes.

2. Use the UP or DOWN buttons to scroll through the entire switching

bandwidth in steps of 25 kHz.

3. To save the selected frequency press the SET-PWR button to store,

the confirmatory “SAVED”message will appear.

Saving Custom Frequency

The transmitter can save up to 24 frequencies to the user customisable channel

bank listed as “VAR XX” in the channel menu. To store a frequency - simply

repeat the above but after selecting the frequency quickly press the SET-PWR

button again whilst the “SAVED” message appears.

Then select the desired custom channel, named “VAR 01” to “VAR 24” and

hit the SET-PWR button to select and display the confirmatory “SAVED”

message.

Please Note:

There are 24 user customisable channels available, which after being set in the

frequency mode menu, are then accessible via the channel mode menu,

explained further below.

Remember to change display mode to “All” to have both menus available.

Resetting the unit will clear all user channel pre-sets.
