BS 216 2-channel Master Station

The BS 216 is designed to function as the master

unit in an ASL Analog Intercom system. It is suit-

able for use in both portable and xed installa-

tions. The BS 216 incorporates its own built-in

switch-mode universal power supply, and ope-

rates as a dual channel power supply for driving

connected beltpacks.

Product features in brief:

■

Separate TALK and CALL buttons with LED indi-

cators for each channel

■

Volume control (LISTEN level) for each channel

■

Power Supply capable of driving fteen BS 15

Beltpacks to full volume

■

AUX input volume control separately adjustable

for each channel

■

30 V DC phantom power at Aux input when ‘mic

level’ is selected

Beltpack

BS 15 1-channel Beltpack

The BS 15 is a 1-channel intercom station housed

in a strong, lightweight ABS case. It is powered via

the intercom line by a BS 216 Master Station or a

BS 181 / BS 286 Power Supply.

Power Supplies

BS 181 1-channel Power Supply

The BS-181 is a 1-channel Power Supply housed

in a steel case. It has the capacity to power up to

fteen BS 15 Beltpacks to full volume. The BS 181

enables cost-eective system powering when only

one channel is needed.

BS 286 2-channel Power Supply

The BS 286 is a 2-channel, switch-mode Power

Supply with an AUX input for program signals. It is

housed in a 1U steel rack-mount case. The BS 286

will safely drive fteen BS 15 Beltpacks when each

is set to full volume. Separate volume controls for

the AUX input allow aux program levels for each

channel to be adjusted independently.

Talkpacks

Features in Detail

Headphone Ampliers – High-quality, push-

pull headphone ampliers contribute to a system

frequency response of 200 Hz to 15 kHz and a

dynamic range of 80 dB. Output is 500 mW @ 200

ohms. A proprietary frequency contouring circuit

optimizes voice range reproduction to ensure

exceptionally high intelligibility even in high ambi-

ent noise environments.

Headset Connections – Both the Master Station

and beltpack accept either dynamic or electret

microphones as standard. Mic gain is adjustable

internally for optimum results with any micro-

phone. A headset detection circuit ensures the mic

pre-amp is active only when a headset is connec-

ted. A volume control enables the user to listen at

any desired volume, and to balance levels on the

two channels of the BS 216 Master Station.

Side Tone – Each user station includes a side tone

trimmer for each channel to allow adjustment of

the operator’s voice level as heard through his or

her own headset or loudspeaker.

Switch-mode Power Supplies – In case of short

circuits, faulty wiring or excessive thermal con-

ditions, the Power Supply will self-protect by

reducing power output, eventually shutting down

under prolonged extreme stress. Once the fault is

corrected, the power supply automatically resets

and restores normal operation.

TALK Function – TALK button with green LED in-

dicator connects to all user stations and beltpacks

on the indicated channel.

CALL Function – The combined audible and

visual CALL alert adapts to both sound- and light-

sensitive environments. An incoming or outgoing

call signal is indicated by a large red LED. Pushing

the CALL button for more than two seconds acti-

vates the internal BUZZER. Volume of the BUZZER

can be trimmed or muted.

AUX INPUT – The 2-channel Master Station

(BS 216) and Power Supply (BS 286) each oer a

balanced auxiliary input (individually attenuated)

normally used to carry the auditorium or on-air

program audio. Inputs may be switched between

line level and microphone level with 30 V DC

phantom powering.

The Basic Series provides a cost-eective solution in more limited applications that require full duplex,

party line communication. All interconnections are made with standard, balanced microphone cable

with XLR-3 connectors. Installation requires no expert knowledge, and clear layout of controls assures

trouble-free operation with a very short learning curve. A current-driven interconnect loop ensures that

operator listening levels do not change as stations are added to or removed from the network.
