Capsule and Battery Installation
A common threaded mount allows the use of a variety of different capsules from
different manufacturers. Capsules are attached with a right-hand thread
A mic capsule is
threaded onto the body
of the transmitter in the
direction shown.
Do not overtighten it.
The lower housing opens
by rotating it in the direction
shown. After the threads are
disengaged, pull the housing
downward until it engages the
detent that holds it open.
The threaded interface is a 1.25”
opening with 28 threads per inch and
three contact rings
To remove the windscreen
from the mic capsule, line
up the blue wrench (that
was included with your
unit) with the flat notches
on the lower threaded area
of mic capsule.
To remove the batteries, pull the eject lever
outward. the battery tips will move outward,
making them easier to grasp.
To insert batteries, close
the eject lever and insert
the upper contacts
first (closest to the mic
capsule). Polarity is
marked on the label in
the bottom of the battery
compartment.
Do not touch the contacts between the mic capsule
and transmitter body. When necessary, the contacts
can be cleaned with a cotton swab and alcohol.

Standby Mode
A brief push of the Power Button turns
the unit on and places it into a “standby”
mode (not transmitting). This allows the
transmitter to be set up without the risk
of creating interference for other wireless
systems that are operating in the vicinity.
A notice will appear briefly confirming
that the RF output of the transmitter is
turned off, followed by the Main Window.
A symbol will blink as a reminder that the
RF output is turned off.

• Pwr Off?: Turns off the transmitter.
• Rf On?: Begin transmitting the
RF signal.
• Backlit: The LCD backlight is set
to come on when any button on
the control panel is pressed, then
stay on for either 30 seconds or 5
minutes, or to stay on all the time.
• About: Displays the model, firm-
ware version, frequency lock and

The unit can also be turned off from any
menu or screen on the LCD by holding
the power button in for the duration of
the countdown.
Battery Condition
An icon on the Main Window indicates
the remaining power of the transmitter
batteries. This battery gauge is most
accurate with the typical voltage drop
across the life of alkaline and dry cell
lithium batteries.

Battery Gauge
Rechargeable batteries give little or no
warning when nearing depletion. If you
use rechargeable batteries in the HHa,
we recommend trying fully charged
batteries first, noting the length of time
that the batteries will run the unit, and
in the future using somewhat less than
that time to determine when the battery
needs to be replaced. The Venue and
other receivers from Lectrosonics offer a
timer function to assist in this process.

Gain
This setting is very important since it will
determine the audio signal to noise ratio
and dynamic range that the wireless
system will deliver. Gain must be set
according to the individual voice, the mic
capsule in use and the handling tech-
nique of the user. LEDs in the control
panel facilitate accurate gain adjustment.

This menu item can also be used to

Default
The default setting simple returns the
transmitter back to the factory settings
and any of the menu items can be read-
justed from that default point.
Input Gain Adjustment
The two bicolor Modulation LEDs (lo-
cated at the bottom of the control panel)
provide a visual indication of the audio
signal level entering the transmitter.
The modulation
LEDs are oriented
and labeled to be
read when holding
the mic capsule in
front of your mouth.
The gain should
be set so that the
-20 LED just turns
red on the loudest
peak.
The LEDs will glow either red or green to
indicate modulation levels as shown in
the following table.
Signal Level -20 LED -10 LED
Less than -20 dB Off Off
-20 dB to -10 dB Green Off
-10 dB to +0 dB Green Green
+0 dB to +10 dB Red Green
Greater than +10 dB Red Red
It is best to go through the following
procedure with the transmitter in the
“standby” mode so that no audio will
enter the sound system, which could
cause feedback.
1) With fresh batteries in the trans-
mitter, power the unit on into
“standby” (no transmission) mode.
2) Press the MENU/SEL button once
to enter the setup menu. Use the
UP/DOWN buttons to select Gain.
Press the MENU/SEL button again
to enter the setup screen.
3) Hold the microphone the way it will
be used in actual operation.
4) Speak or sing at the same voice
level that will actually be used dur-
ing the program, while observing
the modulation LEDs. Use the UP/
DOWN buttons to adjust the gain
until the –20 dB LED starts to
flicker red and the –10 dB glows
green.
5) Once the audio gain has been set,
the signal can be sent through
the sound system for overall level
adjustments, monitor settings, etc.
To do this, the unit must be set to
transmit (see Powering On and
Off, and the Standby Mode on
page 3).
NOTE: Full modulation is
achieved when the -20 LED first
turns red. 30 dB of clean limiting
is available above this point.

TalkBk (talkback) is a “push to talk”
function that is active only while the
button is pressed. The talkback function
provides a communication channel when
used with a receiver equipped with this
function, such as a Venue Wideband
receiver with firmware Ver. 5.2 or higher.
When pressed and held in, the side
button re-directs the audio output to a
different audio channel on the receiver.
As soon as the switch is released, audio
is returned to the program channel.
NOTE: The Talkback function
is only available in the Digital
Hybrid compatibility mode. An
error message will appear if
Talkback is selected while in
another mode.
Power turns the power on and off.
Hold the button in until the countdown
sequence from 3 to 1 is completed. The
power will then be turned off.
Cough is a momentary mute switch. Au-
dio is muted while the button is held in.
Mute is a “push on/push” off function
that toggles on and off each time the
Side Button is pressed. The mute func-
tion defeats the audio in the transmitter,
so it works in all compatibility modes and
with all receivers.
(none) disables the switch.
For detailed information on setting
up the Talkback function and the
Venue receiver, refer to the Installa-
tion Guide for the Venue Wideband
Receiver.
