Safety First !
• Please check the carton box for any kind of damage on
reception of the goods. In case of a damaged carton, please
contact your dealer before opening the carton.
• !!!! Danger !!!! Exposure to high sound levels may cause a
permanent hearing loss. Individuals vary considerably to sound
pressure level induced hearing loss but nearly everyone will
lose some hearing if exposed to high sound pressure levels
for a sufficient amount of time. Therefore it is recommended
that all persons exposed to equipment capable of producing
high sound pressure levels, such as this device, be protected by
hearing protection while installing or operating this unit.
• Read all documentation before operating your equipment.
• Keep all documentation for future reference.
• Save the carton and packing material even if the equipment has
arrived in good condition.
• Should you ever need to ship the unit, use only the original
factory packing.
• Do not spill water or other liquids into or on the unit.
• Make sure power outlets conform to the power requirements
listed on the back of the unit.
• Do not use the unit if the electrical power cord is frayed or
broken.
• Always operate the unit with the AC ground wire connected to
the electrical system ground.
• Set level controls on amplifiers all the way down during power-

up to prevent speaker damage if there are high signal levels at
the inputs.
• Do not connect the inputs / outputs of amplifiers or consoles
to any other voltage source, such as a battery, mains source, or
power supply, regardless of whether the amplifier or console is
turned on or off.
• Power down & disconnect units from mains voltage before
making connections.
• Do not use the unit near stoves, heat registers, radiators, or
other heat producing devices.
• Do not operate equipment on a surface or in an environment
which may distort the normal flow of air around the unit. If the
unit is used in an extremely dusty or smoky environment, the
unit should be periodically “blown free” of dust.
• Do not remove the cover. Removing the cover will expose you
to potentially dangerous voltages.
• Do not drive the inputs with a signal level higher than that
required to drive equipment to full output.
• Do not run the output of any amplifier back into another input.
• In case of mal-function this device should be serviced by
qualified service personnel only.
• The apparatus may not be exposed to dripping or splashing and
no objects filled with liquids may be placed on the apparatus.
• The appliance coupler has to be readily operable to disconnect
the device.

CAUTION: a clipped or distorted audio signal at the input
(overload) will come out as a clipped or distorted signal
at the output, regardless of the output level and DSP
processing power applied to the signal. Clipping occurs
when the signal and/or the applied gain is too high, due
to incompatibility of the signal level, a faulty source,
an impedance mismatch or a human error. Therefore,
monitor incoming signals and do not overload the
inputs. Adjust the output level(s) and gain settings of
your source(s) if necessary. Due to the internal gain
structure of the AudioControl, the output signals may
clip even when the input signals are relatively low. Do
not overamplify audio signals. Boosting certain frequency
bands or overcompressing incoming audio signals may
cause signal clipping, distortion and excessive noise at
the output. If you have to add lots of gain, your incoming
signal may be too weak. In some cases (microphones),
this is unavoidable. AudioControl can help you to
minimize the noise problem: add a noise gate in the
signal path of noisy/weak audio sources and set the
threshold so that no noise is heard when no signal is
present.

Features:
• Easy configuration via graphic installer interface.
• Configurations can be saved/backed up on the computer and
can be transferred to other AudioControl units.
• Stand alone operation: once configured, the unit will operate
without a computer.
• Stand alone graphic installer interface: no need to connect
the AudioControl unit: configure the unit offline, save the
configuration and upload it to the unit when necessary.
• Upgradeable firmware (via RS232) for future additional
features.
• Brushed aluminium panel.
• 12 analog inputs, 6 unbalanced using RCA connectors, 6
balanced using removable euroblock connectors.
• 4 digitally controlled analog gain levels on balanced inputs
(microphone up to line level).
• Digital SPDIF input, can be assigned as 2 additional inputs,
making it a 14 in 8 out unit! In this case no DSP processing can
be assigned to the SPDIF input.
• Digital SPDIF input can be swapped with EQ and Dynamics of
analog input 7 & 8. In this case DSP processing can be assigned
to the SPDIF input.
• 8 unbalanced analog outputs using RCA connectors with
switchable 15 dB output boost.
• Digital SPDIF output with 24 bit, 48 kHz fixed sampling rate
assignable as a copy of a selected analog output (pair).

• 8 dedicated wall control connectors (DIWAC).
• Polarity independent 2 wire connection between wall panel and
AudioControl unit.
• DSP with 48 kHz internal processing sampling rate: parametric
EQ, audio filtering and dynamics processing on the inputs.
• DSP with 48 kHz internal processing sampling rate: parametric
EQ, audio filtering, compressor and limiter on the outputs.
• Integrated chime (ding-dong).
• Automatic sampling rate converter on the digital input: 8 - 24
bit/32 – 96 kHz.
• Paging microphone input (DIMIC product range), fully
configurable paging.
• 1.2 millisecond propagation time from analog input to analog
output.
• 8 paging priority levels.
• 3 x RS232 ports for easy integration with automation systems.
• LED display window for easy status overview of all audio
signals, control signals, and communication ports.

AUDIOCONTROL12.8 is a highly versatile, fully configurable 12 in 8
out audio matrix with built in DSP processing. With the SPDIF inputs
in use, you might even call it a 14 in 8 out unit !
Paging possibilities are virtually endless: a maximum of 120
addressable/programmable paging microphones/extenders can be
connected, each with their own functionality and individual presets
and up to 8 priority levels. A maximum of 8 microphones can be
powered by the AudioControl unit, depending on cable length.
When more units are in use, or when the cables cause substantial
supply voltage drops (power loss), the microphones must be
individually powered by a 24 VDC power supply (see manual of
the connected DIMIC). The microphone push buttons can be
programmed to page zones, zone groups, to play pre-recorded
messages (with optional module installed), Or to control external
devices such as door locks, lights or alarm sounders.The chime,
when enabled, can be activated by pushing the call button on a
paging mic station.
