William Sound WIR RX22-4 User Manual

USED IN THE COURTROOMS AND JURY ASSEMBLY ROOM

SoundPlus 4-Ch Infrared Receiver

Model: WIR RX22-4
Overview

The WIR RX22-4 is a four-channel infrared (IR) receiver, compatible with transmitters operating on
the 2.3-3.8 MHz bandwidth. The sleek, comfortable design features a convenient rotary channel
selector, an easy-to-use on/off and volume control.

Designed for optimal audio quality, easy operation and portability, SoundPlus IR receivers operate
in the 2.3-3.8 MHz bandwidth to minimize high efficiency lighting interference.

The WIR RX22-4 can be used with mono or stereo headphones, earphones or a T-coil neckloop depending on the
preference of the user. Use the T-Coil neckloop for those with hearing aids equipped with a telephone coil (T-Switch).
Each of our courtrooms have dual infrared emitters installed to provide maximum sensitivity and operating range.

When to use the Williams Sound SoundPlus and when to use the Pocketalker Ultra?

The black colored SoundPlus WIR RX-22-4 is a 4-ch IR receiver that is designed for use with the Courtroom’s sound system.
It picks up whatever is spoken into the courtroom’s microphones with the exception of the Nomad E-Podium Sound
System and jury deliberation rooms. The SoundPlus device requires the courtroom’s sound system to be turned on, fresh
AA batteries and the user’s preference of either the headphones or T-Coil neckloop. The IR Emitters are already installed in
the courtrooms and jury assembly room.

For the jury deliberation rooms: Contact Judicial Operations to have them set up the Portable Assisted Listening System
(PALS). The PALS kit consists of a Williams Sound IR Transmitter with a microphone and four SoundPlus IR Receivers. The
PALS kit is completely compatible with the courtroom system.

Other options: The silver-colored Pocketalker Ultra PKT D1 is a personal amplifier device that is NOT
connected to the Courtroom’s sound system. It picks up and amplifies the sounds coming into the mini
microphone that is plugged into the Pocketalker Ultra mic jack. The Pocketalker Ultra does NOT require
any other equipment other than fresh AA batteries, the detachable microphone and the user’s
preference of either the headphones or T-Coil neckloop.

Getting Started

1. Plug the headphone or T-Coil neckloop into the Headphone jack on the

receiver’s control panel.

NOTE: Use the T-Coil neckloop for those with hearing aids equipped with a

telephone coil (T-Switch).

2. Turn the receiver on by rotating the Volume control knob. The ON

power indicator should illuminate RED.

3. Ensure Channel 1 (2.3 MHz) is selected for the hearing-impaired system by

turning the Channel Selector knob on the control panel. Channels 2 (2.8 MHz),

Ch.3 (3.3 MHz), and Ch. 4 (3.8 MHz) are used for the Court Interpreters System.

IMPORTANT: Make sure the receiver frequency matches the transmitter frequency.

4. Make sure the “SoundPlus IR” artwork on the front of the unit is not covered up

while in use. Do not place the receiver in a pocket or purse or it will not work
properly.

5. Adjust the volume to a comfortable listening level.

6. To turn the receiver off, rotate the Volume control knob to the left until it clicks

off. The ON power indicator should not be lit. To prolong the battery life of the
unit, turn the receiver off when it is not in use.

Low Battery Indicator

The “ON” power indicator on top of the unit will flash to indicate low battery levels.
