signal level to the line for persons who may be seated

close tothe microphone

or

speak louder than necessary.

1.03 The

CONFERENCE

2000

is available in four

models: the Q_TAF2A3, the

INSTALLATION

Location

3.01

For

best acoustic performance, the

CONFER-

ENCE

2000 should be installed

in

a room which

does notexceed

25

ft.

(7

.6m)

in

length orwidth, with a

maximum height of 9

ft.

(2.7m). The walls, floor and

ceiling should also be acoustically treated to minimize

echo effect (i.e., carpeton floor, a hard surface ceiling,

drapery covering windows, etc.).

3.02 The acoustic unit should be positioned a minimum

of 3

ft.

(0.9m) from any wall and should be

centrally located on the conference table approxi-

mately equidistant

from

all participants.

3.03

No

participant should be more than 10

ft.

(3.lm)

from the acoustic unit. The surface of the table

directs the voice input; positioning the acoustic uniton

a pedestal adversely affects the performance

of

the

product.

Power Supply

3.04 Input power to the

CONFERENCE

2000

is

provided through a power supply comprising a

transformer and a 12

ft.

(3.7 m) long, twerconductor

cord terminatedbya powerplug. The tranformer steps

the voltage down from 115 Vac to

16

Vac and is

capable ofdelivering a current of 375mA. The power

plug connects into the power jack on the rear

of

the

control module.

Connection to LOGIC Telephone Sets

3.05 Toconnect

the

CONFERENCE2000 to LOGIC-

type telephone sets proceed as follows:

(1) Hold the telephone set in the right hand with

the dial forward.

Page 4

Reissued,

84

07

(2) Hold the control module in the left hand with

the face forward.

(3) Tilt the upper edge of the control module

towards the upper edge

of

the telephone set

and bring the set and module togther so that the

plug

is

firmly in the socket.

Connection

to

SL-1 Electronic Telephone Sets

(LOGIC-style)

3.06 The

CONFERENCE

2000 can be connected to

a LOGIC-style SL-1 setby

following

the

procedure

outlined in 3.05.

For

proper operation however, it is

necessary to make minor wiring modifications to the

SL-1 set and add either a Q

KK

1E Handsfreelnterface

Kit (A0283601) or a QKK3B Automatic Handsfree

Interface Kit (A0283608). When a QKK-type kit

is

used, external power to the control module

is

not

required; refer to Chart

3-5

ofPractice 553-2001-211

for complete details (Wiring

of

the

CONFERENCE

2000

is

similarto the

QUSlC

LOGIC

handsfree unit.)

3.07

For

connection to other than LOGIC-type tele-

phone sets, including NE-500- and NE-2500-type

SL-1 sets, the

NE-D16QD

mounting cord must be

used. Refer to Tables B and C.

Connection

to

SM-1 Telephone Sets (LOGIC-style)

3.08 The

CONFERENCE

2000 canbe connected to

a LOGIC-style SM-1 set by following the

procedure outlined in 3.05.

For

proper operation

however, it

is

necessary to make minor wiring

modifications to the SM-1 set and add a QKK2C

Interface Kit (A0272575).

For

complete connection

instructions refer to Practice 502-8771-200 for the

SM-1 telephone setor Practice 518-8011-210 for the

SM-1 system. (Wiringofthe

CONFERENCE

2000

is

similar to the

QUSlC

LOGIC handsfree unit.)

External Microphones

3.09 When the background noise level

is

so

high

that

the called party may have difficulty hearing,

external microphones located in closerproximity tothe

participant may improve the transmission quality.

When more than one external microphone (customer-

provided)

is

essential, a standard microphone mixer

(customer-provided)

is

required.

Notes: Customer-provided microphones should

meet the following specifications:

• Dynamic

• 10,000 ohm impedance

• 1/4 in. (6.4mm) plug.

Although 600-ohm, electret-type lapel micro-

phones perform well, the battery requirement

(3- to 6-houroperational use) may lead

to

frequent

battery replacement.

3.10 The microphone mixer should be centrally

located, adjacent to the acoustic unit. This ensures

that the external microphones are positioned approxi-

mately equidistant from the acoustic unit.

Note: Commercially available active mixers

(equipped with self-contained amplification cir-

cuits) can be connected to the

CONFERENCE

2000 mixer jack located at the back

of

the control

unit. When external microphones are

in

use, the

microphone switch on the front

of

the control unit

must be set

to

the mic ext position.

3.

11

When the microphone mixer cable is not long

enough to provide a central location for the

acoustic unit, an add-on extensioncord

will

be required.

PRACTICE 512-6261-200

3.12 On completion

of

the

CONFERENCE

2000

installation, the operation testsdescribed

in

Chart 1

must be performed

4. OPERATION

4.01

For

best operation, the following distance and

speech guidelines should be observed:

• Conference participants should

be

seated not

closer than 3

ft

(0.9m) or further than

IO

ft

(3

.1

m)

from the acoustic

unit

• Speech should be

at

normal conversation level.

Lowerlevels of

SJlCech

donotoperatethe voice

switching circuit and, consequently, are not

transmitted Thelevel

of

speechmustbe raised

as the distance from the acoustic unit

is

increased.

Note: The voice-switching circuit permits trans-

mission

of

speech in one direction at a time. The

circuit switches to transmit when you speak and

to receive when the distant party responds.

4.02 The acoustic unit represents the called party.

Speech should be directed toward the acoustic

unit at all times. Speech directed away from the unit

sounds hollow at the called party location.

S.

MAINTENANCE

5.01 If the

CONFERENCE

2000 must be returned

for repair, itshould be packaged using the cartons

listed in Table A to protect against damage during

shipping.

5.02 The

CONFERENCE

2000 should be treated as

a piece

of

fine

furniture (especially the acoustic

unit), and should not be subjected to temperature

extremes during use, storage

or

shipment

6.0 CONNECTIONS

6.01 The

CONFERENCE

2000 is available as

follows:

• An optional

NE-D16QD

mounting cord

(standard on QTAF2C3)is available for con-

nection to single-line

or

multiline telephone

sets. The

NE-D16QD

cord converts the

modular connection to spade-tip connectors.

• Equipped with a 15-pin connector which is

compatible with LOGIC-style telephone sets. 6.
