ADA COURTROOM ASSISTIVE LISTENING SYSTEM

Description:

The Basic Courtroom System, model WIR SYS 1, is the complete assistance solution for the courtroom. Listeners wear wireless RX22-4receivers to hear the proceeding anywhere in a 28,000 ft2 area**. For the severely hard of hearing, theRX22-4can be equipped with a neckloop (included) to amplify their telecoil equipped hear-

ing aid. SoundPlus infrared technology ensures privacy and

message of the proceeding doesn’t travel

outside the walls of the courtroom.

 

 

Each WIR SYS 1 package includes: one (1) TX9 emitter, one (1)

modulator, four (4) body-packstyleRX22-4

receivers, four (4) HED 021 Headphones, one (1) neckloop and one

005 rack panel kit. The WIR SYS 1 meets

and exceeds government ADA regulations for public hearing

and is backed by a five-yearwarranty.*

If you’re not getting sufficient coverage with a single, properly installed TX9 Emitter, you may need

to add additional WIR TX9 Emitters to achieve full

your listening area. Figures 8a and

8b illustrate how multiple emitters can be used for large

installations.

Bid Specs

Modulator, Model MOD 232

The infrared system shall consist of separate modulator and emitter

with portable receivers. The modulator unit

shall be a half-rackstyle, metal enclosure. A rack panel shall be

mount one or two modulator units within a

single EIA rack space. An adjustable floor stand and mounting

be available to mount the modulator and

emitter together for portable operation.

 

The modulator shall provide two channels of selectable FM carrier

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

coaxial cable with BNC-typeconnectors. A

BNC–typebaseband input jack and baseband output jack shall be

on the modulator. The modulator shall be

powered by an external 24 VAC, 10 VA, 50-60Hz power supply,

a three-pinMolex power connector.

It shall have a rocker-typepower switch, power LED indicator, four

indicator LEDs and two bar graph-typeLED

audio indicators. The modulator shall have a modulated IR LED on

panel for testing purposes, and a head-

phone jack that accommodates mono and stereo 1/4" headphones,

monitoring switch. The modulator shall

have two rotary audio input level controls, and a screwdriver

for varying the input compression from

1:1 to 4:1. The modulator shall have two timers that automatically

the carriers when there is no audio signal

present for 15 minutes. The modulator shall have two combination

that accept 3-pinXLR plugs for balanced

microphone input or 1/4" TRS plugs for balanced or unbalanced line-

inputs. The XLR inputs shall be low impedance,

accept signal levels from 100 µV to 90 mV and supply 15 V simplex

DIN45596. The TRS jacks shall accept bal-

anced or unbalanced audio signal levels from 21 mV to 10 V. The

shall have CE, FCC, RoHS, and WEEE

approval and carry a five-yearparts and labor warranty.

 

The modulator shall be the Williams Sound Corp. model MOD 232.

 

Emitter, Model TX9

 

The emitter shall be contained in a metal enclosure with a shatter-

lens. The emitter shall include an omni-direc-

tional mounting bracket for permanent installation and a bracket

available for mounting on a floor stand for

portable installations. Each emitter shall be powered by a 24 VAC, 50

-60Hz power supply. The power connector

shall be a 3-pinMolex-type.The emitter shall have aBNC-type50

input and a BNC-typebaseband 50 ohm

output jack. The emitter shall have a repeater circuit to allow

of emitters to operate from the base-

band signal. The emitter shall have a visible LED indicator for power

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 cov-

erage area of 28,000 sq ft (2,600 sq m) in single channel mode and

ft (1,700 sq m) in two channel mode when

using the RX22-4receiver. The emitter shall beconvection-cooled,

fans. The emitter shall have CE, FCC, RoHS,

and WEEE approval and carry a five-yearwarranty on parts and labor.

 

The emitter shall be Williams Sound Corp. model WIR TX9.

 

Four-ChannelReceiver, ModelRX22-4

 

The receiver shall be a body-packtype with IR detector lens behind

unit. The unit shall have a lanyard for hands-

free operation. The receiver shall have a rotary-typevolume control.

shall operate for 60 hours with two AA

alkaline batteries and for 30 hours per charge with NiMH AA batteries.

receiver shall be charged without battery

removal via charger contacts in the case. A drop-incharger accessory

recharge the batteries in 8 hours when used with

CHG 3512 charger. The receiver shall be housed in an impact resistant

case with a hinged battery door that does not

separate from the receiver. The receiver shall receive 2.3 MHz, 2.8 MHz,

or 3.8 MHz modulated IR signals with 50 µS

de-emphasis.The receiver shall have a 3.5 mm stereo phone jack and accommodatelow-impedancemono or stereo ear-

phones and headphones. The receiver shall accommodate neckloop

couplers. The receivers shall provide 110 dB

SSPL90 output with EAR 013 earbud-typeearphone.

 

The system electrical frequency response shall be 25 Hz to 16 kHz, +1, -3

the signal-to-noiseratio shall be 60 dB. The

receiver shall have CE, FCC, RoHS, and WEEE approval. The receiver shall

by a five-yearparts and labor warranty,

excluding earphones, headphones, batteries and chargers.

 

The receiver shall be the Williams Sound Corp. model WIR RX22-4.
