ASL Intercom
eadquartered in Utrecht, the Netherlands,
ASL Intercom BV was established in 1985 by
H
current Managing Director Eric de Bruyn.
Formerly a founding principal of Ampco Pro Rent,
a highly regarded Dutch sound hire rm, de Bruyn
formed ASL Intercom with the immediate goal of
building intercoms suited to the extreme demands of live entertainment and broadcast production in both portable and installed systems.
The company has since broadened into industrial
and commercial applications, and now oers a
full line of analog, digital and wireless intercoms
backed by prompt, personalized technical support.
The ASL Analog Intercom line currently comprises
both the Basic Series and Pro Series of single and
multi-channel systems. ASL also oers the Wireless
Series intercoms (operating in the 2.4 GHz band),
the Cue Light System and a wide range of Intercom
Accessories.
ASL Analog Intercom Systems
ASL Analog Intercom systems have a proven track
record of reliable operation in the most demanding live production, broadcast and industrial
applications. Two Series are available to meet
every need, from single-channel systems with
only three or four user stations to highly complex,
multi-channel systems with multiple speaker stations as well as both wired and wireless beltpacks.
Regardless of system size, all ASL Analog Intercoms
are easy to install and simple to operate. Perhaps
most importantly, all will provide reliable and highly intelligible voice communications, even after
years of hard use in stressful work environments.

Basic Series: Intercom simplicity
The Basic Series provides a cost-eective 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.

Features in Detail
Headphone Ampliers – High-quality, push-
pull headphone ampliers 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 ambient 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 microphone. A headset detection circuit ensures the mic
pre-amp is active only when a headset is connected. 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 conditions, 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 indicator 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 lightsensitive environments. An incoming or outgoing
call signal is indicated by a large red LED. Pushing
the CALL button for more than two seconds activates 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 oer 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.
Master Station
BS 216 2-channel Master Station
The BS 216 is designed to function as the master
