The COM108 is a compact but versatile public address mixing
amplifier which offers solutions for small to medium size audio
systems in commercial installations. Typical application are
background music systems in retail stores, bars, restaurants
and office buildings.
The compact and simple design allows installation in any
location and operation through any possible user.
COM108
Public Address Amplifier 80W 100V
The amplifier is designed using Class-D amplifier technology
and delivers an output power of 80 Watt to constant voltage
(100V and 70V) or low impedance (4 Ohm) audio systems. A
switch mode power supply allows compatibility with a wide
variation of mains voltages for global compatibility.
A stereo line input allows connection for a wide variation of
audio sources such as media players, radio tuners, internet
audio players, ... and many more. A balanced mic / line input
allows connection for an announcement microphone with
compatibility for condenser microphones using the integrated
phantom power supply (15V). A priority switch overrides the
background music when enabled, and compatibility with voice
file players is guaranteed by the wide gain adjustment
possibility (0 dB - +50 dB).
The COM108 is a table-top standing device, while rack
mounting in 10.5" or 19" equipment racks is possible using an
optionally available mounting set (MBS310).
Applications:
Bars, restaurants•

Architects’ and Engineers’ Specifications:
The Amplifier shall be a constant voltage 100 Volt type, containing one controllable amplifier channel with an output power of 80
Watt. The amplifier shall use Class-D Amplifier technology while being powered by a switching power supply. It shall have integrated
circuitry to protect against short-circuits, mismatched loads and over-heating. Additionally, the load shall be protected against DC
faults and a clip limiter shall automatically reduce the input gain at onset of distortion. The unit shall be housed in a convection
cooled enclosure, providing maximum reliability while keeping maintenance and noise levels at a minimum. The front panel shall
contain an AC power switch accompanied by a blue power indicator LED and channel operation indicator LED’s. Two green signal
LED’s indicating the presence of an input signal and it’s level exceeding the -20 dB level, a clip LED indicating the channel operation at
maximum level and a protection LED indicating any fault detected shall be provided on the amplifier’s front panel. In addition a 3.5
mm jack connection on the front panel shall be implemented, allowing convenient connection possibilities for portable devices such
as laptops, smartphones and tablets. Besides the output master control, a two band tone control shall be provided, the master
volume control will allow regulation of the overall output volume while the two band tone controls will allow bass / treble adjustment
within a range of ± 12 dB. The output connection shall be performed using a 4-pin Terminal block connector with multiple output
possibilities including 100 V, 70V and low impedance (4 Ohm). On the back panel, an unbalanced stereo line input connection shall
be implemented through RCA connectors, another input shall be possible through a balanced mono type input allowing easy
connection of microphones. A 15 V phantom power switch will allow connecting condenser microphones. Both inputs shall have
individual input mixing controls. A priority switch shall be provided whereby other audio sources will be eliminated once a signal is
present on this input, when enabled it shall also override the priority contact. A priority mute contact shall be provided, allowing easy
muting of the background music. This will be convenient for situations where a separate emergency system is installed and complete
background music muting is required at occasion of a fire alarm. The emergency system contacts can be linked to this contact input.
The amplifier shall operate on a 100 ~ 240 V AC / 50 Hz mains network and shall be equipped with a removable power cord having a
standard shuko (CEE 7/7) AC plug. The connector on the amplifier chassis shall be a fused IEC C14 type. The amplifier shall be
housed in a compact half 19” rackspace enclosure which can be used for desktop installation or mounted in an equipment rack
using (optionally available) mounting adapters. The half 19” rackspace enclosure allows single installation in a 10.5” equipment rack,
or side-by-side (two devices) in a 19” equipment rack it’s weight shall not exceed 2.8 Kg.
