BP60 Belt Pack & EM60 Lavaliere Mic/IR Emitter

The lavaliere microphone/IR emitter should be worn at

the collarbone level by the instructor. It captures the

wearer’s voice and sends it to the battery powered belt

pack. The belt pack uses the audio to modulate an RF

signal which, in turn, modulates an IR emitter in the

lavaliere unit. Thus, the IR emotter bathes the room

with the IR signal which is picked up by IR60 sensors

strategically placed throughout the room. It is capable

of transmitting on either of two channels so that two

microphones can be in use in the same room without

interfering with each other.

HHM60 Hand Held IR Microphone

The HHM60 is a battery powered hand held infrared

microphone. When turned on, it captures the users

voice and transmits it via an IR signal to IR60 sensors

mounted at various locations around the room. IR

emitters are located at the bottom end of the micro-

phone and near the top opposite the power switch, so

it is important that at least one of these locations is

not covered when in use. The HHM60 is capable of

transmitting on either of two channels so that two

microphones can be in use in the same room without

interfering with each other.

IR60 Dome Infrared Sensor

The IR60 Dome Sensor contains six infrared sensor

diodes. Its designed to be installed at a strategic

location in a classroom, usually on the ceiling, to

receive the IR signals from the hand held and

lavaliere microphones. The output of the device is

an RF signal which is available at an “F” type

connector on the back of the unit. The output RF

signal is forwarded to the SRR60 receiver through

RG59 75 ohm coaxial cable. The SRR60 receiver

can accept input from up to three of these devices.

BC60 Battery Charger for Microphones

This battery charger plugs into the HHM60 or BP60

unit to charge the AA size Ni-MH batteries installed

in them. Two outputs are provided so one charger can

charge two microphones at once.

Do not attempt to charge Ni-Cd batteries, or other

rechargeable cells with less than 2000 mAH

capacity, with this unit since the charging rate

would be to high for them.

UNDER NO CIRCUMSTANCES SHOULD THIS UNIT

(OR ANY CHARGER) BE USED TO CHARGE ALKA-

LINE BATTERIES!!

RMB60 Rack Mount Brackets for SRR60 Receiver

Rack mount brackets are available if it is desirable

to install the SRR60 receiver in a rack cabinet. The

SRR60 Receiver is pictured below with the brackets

installed.
