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.

• Resume: Continue operating in

the same condition as before.

• 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

compatibility mode.

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.

Programmable Switch

Functions

A special button (the Side Button)

on the outside of the housing can be

conﬁgured to provide several different

functions, or to be inoperative.

The ProgSw on the control panel opens

a setup screen to select the function of

the Side Button.

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.
