Quick Start - Lectronics DCHT Quick Start Manual

Quick Start

1) Install good batteries and turn
power on (see page 4).
2) Set compatibility mode to
match the receiver (see page
8).
3) Connect signal source, select
input type and adjust input
gain for optimum modulation
level (see pages 8 and 9).
4) Set or sync frequency to
match receiver (see page 9).
Also see receiver manual for
scanning procedure.
5) Set encryption key type and
sync with receiver (see pages
10 and 11).
6) Set programmable switch to
desired function (see page
11).
7) Verify RF and audio signals
are present at the receiver
(see receiver manual).

Adjusting the Input Gain for
Analog Inputs
For analog gain adjustment, two
multi-color LEDs on the top panel,
one for each channel, provide a vi-
sual indication of the audio signal
level entering the transmitter. The
LEDs will glow either red or green
to indicate modulation levels as
shown in the following table.
8
Signal Level
Less than -20 dB
-20 dB to +0 dB
+0 dB and greater
NOTE: This procedure is
used for analog inputs only.
AES digital input is factory
set at the industry standard
level. The LEDs on the top
panel will glow blue when the
audio level reaches about
-40 FS.
It is best to go through the follow-
ing procedure with the transmitter
in the standby mode so that no
audio will enter the sound system
or recorder during adjustment.
1) With fresh batteries in the
transmitter, power the unit
on in the standby mode (see
previous section Powering On
in Standby Mode).
2) Navigate to the Gain setup
screen.

3) Position a microphone the way
it will be used in actual opera-
tion and have the user speak
or sing at the loudest level
that occur during use, or set
the output level of the audio
device to the maximum level
that will be used.
4) Use the
and
to adjust the gain until the LED
glows green most or all of the
time, and flicker red during the
loudest peaks.
