Realistic 32-1228 is a Three-Channel FM Wireless Microphone System that allows you to move freely within a 200-feet range while using microphones.

With its three separate channels, you can operate up to three microphones simultaneously, making it suitable for various applications such as presentations, public speaking, or group discussions. Each channel has its own volume control, providing independent adjustment for each microphone's output.

The system offers AC or DC operation for the receiver, giving you the flexibility to use it in different settings. It features a single telescoping antenna for the receiver, ensuring optimal signal reception.

M I C R O P H O N E B A T T E R Y

Install two AA batteries in each tran

smitter. For longest battery life, we

recommend alkaline batteries (Radio

Shack Cat. No. 23-552).

1. Open the transmitter's battery com

partment cover by pressing it in the

direction of the arrow and iifting it up.

Follow these steps to connect your

1. Be sure the POWER switch is set to

off and the VOLUME controls are set

to minimum.

2. Instail the AA batteries observing the

polarity (-t-and—) symbols marked

in the battery compartment.

3. Close the battery com partment cover.

The BATTERY indicator lights when

battery power is low. Use fresh re

placement batteries of the same type.

b a t t e r i e s i n s i d e t h e t r a n s m i t t e r . E v e n

leak-proof batteries can ieak damaging

chemicais.

2. Use a shielded audio connector

cable with standard RCA phono

plugs. Connect the receiver's LINE

jack to the line-or aux-input of your

PA amp, tape recorder, mixer, or

other input component.

3. Once you connect the receiver to the

PA system, connect the AC cord to a

standard outlet.

If you are using the system for a portable

application, connect a DC power source

to the DC12.6V jack.

Notes:

• If you connect both AC and DC

power, AC power has priority.

• The system has a recommended

operational range between 4 and

200 feet

• The DC power source must provide

at least 150 mA at 12 volts, and the

plug's center contact must be posi

tive. We recommend Radio Shack's

DC power cord (Cat. No. 270-1534A).

• Cider PA systems have only mlc-

level Input jacks. In this case, connect

the receiver's MICRCPHCNE jack

to the mic Input jack on the PA system.

Use a shielded microphone cable

with standard 1/4-Inch phone plugs.

• If you are using the line- or aux-lnput

jack of your amp for another source,

output jacks to send signals to two

places at the same time-an ampli

ﬁer and a tape recorder, for example.

OPERATION

Here are a few important operating

guidelines that might help you as you

become familiar with your system.

RECEIVER OPERATION

1. Raise and extend the receiver's

antenna.

by turning each channel's volume

control clockwise.

TRANSMITTER OPERATION

1. Clip the microphone to the desired

location. Three to six inches from

your mouth is best.

2. Clip the transmitter to your belt or

pocket. Keep the microphone cable

as straight as possible. Be sure there

are no knots in the cable.

3. Set the transmitter's OFF-STANDBY-

TALK switch to TALK or STANDBY.

When you turn on each transmitter,

speak into the microphone and adjust

the volume control on the receiver

and/or your ampliﬁer for the desired

output level.

HI/LO POWER OPERATION

When you operate the transmitter within

10 to 15 feet of the receiver, set the

t r a n s m i t t e r ' s H I / L O s w i t c h t o L O t o

m i n i m i z e i n t e r f e r e n c e f r o m o t h e r

channels.

When you operate the transmitter more

than 10 to 15 feet from the receiver,

set the transmitter's HI/LO switch to HI.

Note: Avoid operating the transmitters

less than three feet from the receiver.

This can cause audio interference.

M U T E A N D S TA N D B Y O P E R AT I O N

You can turn off the microphone on your

system momentarily or for a long

period of time, as necessary.

M U T E O P E R A T I O N

Note: Turn off any receiver channels

before turning off your transmitter to

prevent pops.

C H A N N E LS O F O P E R AT IO N

Your wireless microphone system has

three different frequencies 49.830MHz,

49.855MHz, 49.892MHz. This lets you

use the three frequencies at the same

time/place.

TROUBLESHOOTING

We do not expect you to have any

problems with your three channel mi

crophone system, but if you do, the

solution is probably on this page. If you

still need assistance, contact your local

R a d i o S h a c k s t o r e .

If you experience interference with your

system

• Your wireless microphone system

uses the same radio frequency as

cordless telephones, remote control

toys, and wireless alarm systems.

Interference can occur if you operate

your system near these products.

• Other potential interference sources

include computers, wireless intercoms,

ﬂuorescent lights, and electrical app

liances.

If your wireless microphone does not

work

• Be sure the power cord is connected.

• B e s u r e t h e P O W E R s w i t c h i s O N .

• Be sure the receiver's antenna is fully

extended.

• Be sure the receiver's antenna is not

near to or touching a metal surface.
