MIXTRIM and MIXMODE

Since this is a dual receiver that can be used with cam-
eras that offer only a single input in the slot, special op-
tions are available to allow the audio from the receivers
to be mixed to either one or both audio output channels.

The MIXMODE setting determines which audio signal
appears at which output channel:

•

MIXBOTH mixes the audio and delivers the mix to
both output channels.

•

MIXTO 1 mixes the audio and delivers the mix to
output channel 1.

•

MIXTO 2 mixes the audio and delivers the mix to
output channel 2.

•

DIRECT keeps the audio separated and delivers
receiver 1 audio to output channel 1, and receiver 2
audio to output channel 2.

The MIXTRIM

setting applies attenuation up to 20dB in

1 dB steps to adjust the ratio of the two audio signals in

the mix. This adjustment takes effect only when a mix

mode is Selected (it is ignored when the mix mode is

set to DIRECT).

IMPORTANT: The LEVEL setting in the other

setup screen (see previous page) is hardware-
based and affects the output level regardless

of which mix mode is selected. MIXTRIM then

applies attenuation to that level setting resulting in

the final level delivered to the output channel. It is

good practice to set the LEVEL of both receivers

to the same value when using a mix mode.

When a MIXMODE is Selected, each audio signal is au

tomatically attenuated by 6 dB prior to the mixing. This
is done to avoid overload and potential distortion since
mixing increases the level by 6 dB. The same input gain
on the camera or mixer can generally be used regard-
less of whether or not a mix mode is being used in the
receiver.

TONE

The TONE setup screen enables an audio test tone at
the receiver output for precise level matching with other
equipment. The first screen prompts you to press the

UP or DOWN button to enable the tone at the receiver

output.

The first screen prompts you

to press the UP or DOWN

button to start the tone.

Once the button is pressed, a 1 kHz tone is enabled,

and its level can be adjusted with additional presses on

the UP or DOWN buttons.

he level set here will be retained in the regular oper-

ating mode (it will supersede the setting made in the

LEVEL setup screen). The test tone has 1% distortion

and is intended for confirmation of output levels only.
To exit the test tone screen and stop the tone press the

BACK button.

Front Panel Shortcuts

A convenient shortcut is available from any setup
screen that displays the receiver selection option
(switching diversity mode with two separate receivers).

Once the value has been set on one receiver, the same

value can be copied to the other receiver with a simple
button push combination.

For example, in the Setup Levels screen, holding the

MENU button and pressing the UP arrow will copy the

value from Receiver 2 to Receiver 1. The arrow key
determines the “destination” of the value setting. UP

sets the value on Receiver 1, and DOWN sets the value

on Receiver 2.
