Thank you for purchasing TOA’s Audio Interface Unit.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.
1. IMPORTANT Safety INSTRUCTIONS
•Read these instructions.
•Keep these instructions.
•Heed all warnings.
•Follow all instructions.
•Do not use this apparatus near water.
•Clean only with dry cloth.
•Do not block any ventilation openings.
Install in accordance with the manufacture's
instructions.
•Do not install near any heat sources such
as radiators, heat registers, stoves, or other
apparatus (including amplifiers) that produce
heat.
•Do not defeat the safety purpose of the
polarized or grounding-type plug.
A polarized plug has two blades with one
wider than the other. A grounding type plug
has two blades and a third grounding prong.
The wide blade or the third prong are provided
for your safety. If the provided plug does not
fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
•Protect the power cord from being walked on
or pinched particularly at plugs, convenience
receptacles, and the point where they exit
from the apparatus.
•Only use attachments/accessories specified
by the manufacturer.
•Use only with the cart, stand, tripod, bracket,
or table specified by the manufacturer, or sold
with the apparatus.
When a cart is used, use caution when moving
the cart/apparatus combination to avoid injury
from tip-over.
•Unplug this apparatus during lightning storms
or when unused for long periods of time.
•Refer all servicing to qualified service
personnel. Servicing is required when
the apparatus has been damaged in any
way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does
not operate normally, or has been dropped.
2. SAFETY PRECAUTIONS
•Before installation or use, be sure to carefully read all the instructions in this section for correct
and safe operation.
•Be sure to follow all the precautionary instructions in this section, which contain important
warnings and/or cautions regarding safety.
•After reading, keep this manual handy for future reference.
WARNING
Indicates a potentially hazardous situation
which, if mishandled, could result in death or
serious personal injury.
When Installing the Unit
•Do not expose the unit to rain or an
environment where it may be splashed by
water or other liquids, as doing so may result
in fire or electric shock.
•Avoid installing or mounting the unit in
unstable locations, such as on a rickety table
or a slanted surface. Doing so may result in
the unit falling down and causing personal
injury and/or property damage.
2
•Since the unit is designed for indoor use, do
not install it outdoors. If installed outdoors, the
aging of parts causes the unit to fall off, resulting
in personal injury. Also, when it gets wet with
rain, there is a danger of electric shock.
When the Unit is in Use
•Do not place cups, bowls, or other containers
of liquid or metallic objects on top of the unit.
If they accidentally spill into the unit, this may
cause a fire or electric shock.
CAUTION
Indicates a potentially hazardous situation
which, if mishandled, could result in moderate or
minor personal injury, and/or property damage.
When Installing the Unit
•To avoid damage to the unit and/or connected
equipment:
·Never connect the IR-820SP or IR-802T
connection terminal to a PC or LAN.
· Never short-circuit the terminal to ground.
•Be sure to follow the instructions below when
rack-mounting the unit. Failure to do so may
cause a fire or personal injury.
·Install the equipment rack on a stable, hard
floor. Fix it with anchor bolts or take other
arrangements to prevent it from falling down.
· Rack-mounting screws are not supplied with
the unit. Prepare them that are appropriate
for the equipment rack.
FCC Compliance
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause
undesired operation.
Any modifications made to this device that are not approved by TOA Corporation may void
the authority granted the user by the FCC to operate this equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference with radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of
the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and the receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
•Consult the dealer or an experienced radio/television technician for help.
3. GENERAL DESCRIPTION
The IR-801AF is an Audio interface unit designed for exclusive use with TOA’s Infrared wireless
microphone system* consisting of the IR-310M Infrared Wireless Microphone, IR-802T Infrared
Wireless Tuner, and IR-820SP Infrared Wireless Speaker.
The IR-801AF is equipped with a single channel wireless tuner having a fixed frequency. It provides
a closed contact output for controlling external equipment, and audio signals from the IR-310M to
be output to external equipment when receiving a control signal transmitted through the Function
button operation of the IR-310M.
* A PA system designed for use in the school classrooms measuring about 10 m x 10 m (30 ft. x
30 ft.).

4. FEATURES
•Only a single CAT. 5 straight cable fitted with RJ-45 connecters for connections from the IR-801AF
to each of the IR-802T and the IR-820SP.
•Provides outputs of audio signals from the IR-310M and a closed contact while the IR-310M’s
Function button is being pressed. (This function is enabled only when the IR-310M’s transmitting
frequency is set to Channel “A.”)
•Power is supplied from the IR-802T.
•A half-rack-mount size. It can be mounted in a 19-inch EIA standard rack using the optional rack
mount kit.
5. Handling PRECAUTIONS
•Install the unit as far as possible from fluorescent lights, digital equipment, PCs and other devices
that generate high-frequency noise.
•When cleaning, be sure to first switch off the unit’s power, then wipe with a dry cloth. If the unit is
extremely dirty, use a cloth moistened in a neutral detergent. Do not use benzene, thinner, alcohol
and chemically-processed towels, as they can discolor or deform the unit’s exterior.
