SoundPlus® Value Courtroom System
ADA Courtroom Assistive Listening System
The Value Courtroom System, model WIR SYS 3, is the ideal
hearing assistance package for courtrooms with limited budget
resources. Participants wear headset style receivers to listen to
the courtroom proceeding at the volume of their comfort level
anywhere up to 28,000 sq. ft. For the severely hard of hearing,
the RX22-4 receiver can be used with a neckloop (included) to
amplify the participant’s telecoil equipped hearing aid. SoundPlus
infrared technology ensures privacy and security: the message of
the proceeding will not travel outside the walls of the courtroom.
Each WIR SYS 3 package includes: one (1) TX9 emitter, one (1)
MOD 232 modulator, three (3) underchin RX18 receivers, one (1)
RX22-4 receiver, one (1) EAR 022, one (1) CHG 518 charger, one
(1) NKL 001 neckloop and one (1) RPK 005 rack panel kit. The
WIR SYS 3 meets and exceeds government ADA regulations for
public hearing assistance, and is backed by a five-year warranty.*

Bid Specs
Modulator, Model MOD 232
Emitter, Model TX9
The infrared system shall consist of separate modulator and emitter
units, with portable receivers. The modulator unit shall be a half-rack
style, metal enclosure. A rack panel shall be available to mount one
or two modulator units within a single EIA rack space. An adjustable
floor stand and mounting bracket shall be available to mount the
modulator and emitter together for portable operation.
The emitter shall be contained in a metal enclosure with a shatterresistant lens. The emitter shall include an omni-directional mounting
bracket for permanent installation and a bracket shall be available
for mounting on a floor stand for portable installations. Each emitter
shall be powered by a 24 VAC, 50 VA, 50-60 Hz power supply. The
power connector shall be a 3-pin Molex-type. The emitter shall have
a BNC-type 50 ohm baseband input and a BNC-type baseband 50
ohm output jack. The emitter shall have a repeater circuit to allow
multiple numbers of emitters to operate from the baseband signal.
The emitter shall have a visible LED indicator for power and for
baseband signal. Carrier frequency is 50KHz to 8 MHz. The emitter
shall shut off when the baseband signal is not present. The emitter
shall provide an effective coverage area of up to 28,000 sq ft (2,600
sq m) in single channel mode and up to 18,000 sq ft (1,700 sq m)
in two channel mode when using the RX22-4 receiver. The emitter
shall be convection-cooled, without fans. The emitter shall have CE,
FCC, RoHS, and WEEE approval and carry a five-year warranty on
parts and labor.
The modulator shall provide two channels of selectable FM carrier
signals; 2.3/2.8/3.3/3.8 MHz, so that a single modulator can be
used to simultaneously transmit up to two channels, and two
modulators can be ganged together to transmit up to four channels
simultaneously. The carrier signals shall use 50 kHz deviation
and 50 µS pre-emphasis. The carrier signals (baseband) shall be
transmitted to one or more emitters by 50 ohm RG58 coaxial cable
with BNC-type connectors. A BNC–type baseband input jack and
baseband output jack shall be provided on the modulator.
The modulator shall be powered by an external 24 VAC, 10 VA,
50-60 Hz power supply, connected via a three-pin Molex power
connector. It shall have a rocker-type power switch, power LED
indicator, four carrier indicator LEDs and two bar graph-type LED
audio indicators. The modulator shall have a modulated IR LED on
the front panel for testing purposes, and a headphone jack that
accommodates mono and stereo 1/4” headphones, and channel
monitoring switch. The modulator shall have two rotary audio input
level controls, and a screwdriver adjustable control for varying
the input compression from 1:1 or 2:1 . The modulator shall have
two timers that automatically shut off the carriers when there is no
audio signal present for 15 minutes. The modulator shall have two
combination input jacks that accept 3-pin XLR plugs for balanced
microphone input or 1/4” TRS plugs for balanced or unbalanced
line-level inputs. The XLR inputs shall be low impedance, accept
signal levels from 100 µV to 90 mV and supply 15 V simplex power
per DIN45596. The TRS jacks shall accept balanced or unbalanced
audio signal levels from 21 mV to 10 V. The modulator shall have
CE, FCC, RoHS, and WEEE approval and carry a five-year parts
and labor warranty.
The modulator shall be the Williams Sound model MOD 232.
The emitter shall be Williams Sound model WIR TX9.
Receiver, Model WIR RX18
The receiver shall be an under-chin stetho style with an IR detector
lens in the face of the unit. The receiver shall have a rotary type
volume control and the power switch shall be built into the arms of
the unit so it will automatically shut off when not in use. The receiver
shall operate for seven hours per charge with the BAT AP07D
NiMH battery pack. The receiver shall be housed in a black and
grey plastic case. The receiver shall have a three position selector
switch for 2.3 MHz, stereo or 2.8 MHz modulated IR signals. The
receiver shall provide 120dB SSPL90 output. The system electrical
frequency response shall be 200Hz to 8kHz and the S/N ratio shall
be 60dB at 10m. The receiver shall have CE, RoHS and WEEE
approval and be covered by a five-year parts and labor warranty (90
days on battery pack).
The receiver shall be the Williams Sound model WIR RX18.
Four-Channel Receiver, Model RX22-4
The receiver shall be a body-pack type with IR detector lens
behind face of the unit. The unit shall have a lanyard for hands-free
operation. The receiver shall have a rotary-type volume control. The
receiver shall operate for 60 hours with two AA alkaline batteries
and for 30 hours per charge with NiMH AA batteries. The receiver
shall be charged without battery removal via charger contacts in the
case. A drop-in charger accessory shall recharge the batteries in 8
hours when used with CHG 3512 charger.
The receiver shall be the Williams Sound model WIR RX22-4
