Safety information
• 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 are 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.
• 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 AUDIOSYSTEM, the output
signals may clip even when the input signals are relatively low. Do
not over amplify audio signals. Boosting certain frequency bands or
over compressing 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.
NOTE: This is the out-of-the-box manual of your AUDIOSYSTEM8.8.
A full manual and GUI guide can be found on our website. If you
want customized configurations, adjustments and a total solution
for your specific application, please seek the online manual.
The apart-team hopes you enjoy our product. We enjoyed
developing this product and guarantee it will serve as a solution for
every kind of implementation.

AUDIOSYSTEM8.8 is an audio matrix with 4 stereo line inputs, 4
stereo D-class amplified outputs and 2 stereo line outputs (copies
of amplified outputs). The AUDIOSYSTEM8.8 also has 4 stereo FM
RDS tuners built-in. Together with this the AUDIOSYSTEM8.8 has a
paging input and an emergency mute.
The unit may be controlled through our DIWAC wall panels and has
a built-in webserver for TCP/IP connection for system integration
and/or control through any mobile device or computer that has a
web browser installed.

Connecting the paging microphone
As paging microphone for the AUDIOSYSTEM8.8 you can use
any microphone and contact input. Apart provides the MICPAT D
as a solution. To make the paging microphone compatible with
the AUDIOSYSTEM8.8, cut the wires from the Micpat-D Din-5
connector and connect them to a 5-way Euroblock connector. The
picture below shows how to connect the wires of the Micpat-D to
the respective Euroblock connector.

Front panel
1. Output status: These leds indicate the status of the output
zones. When a zone is active the corresponding led will be lit.
The leds also indicate the status of the amplifiers, when an
amplifier is short circuited, the output led will start to blink.
2. Power led: lights up when mains power is present and the unit
has been switched on.
3. Removable rack ears left and right.

1. Power inlet: Connect the power cord here.
2. Power switch: Power the unit on and off.
3. Paging mic: Connection to MICPAT-D. A microphone balanced
input is provided with a contact closure.
4. The wall controls (DIWAC): Only one control per connection
is allowed, resulting in a maximum of 8 wall controls per
AUDIOSYSTEM8.8. The DIWAC may not be daisy chained.
5. Amplifiers: There are 8 class D amplifiers in the
AUDIOSYSTEM8.8. Speakers are connected with the female
euroblocks. Each output is protected against short circuit,
thermal overload and DC error.
6. Line outputs: These are copies of amplifier outputs 3A, 3B, 4A
and 4B. Used for additional power amplifiers or 100V amplifiers.
7. Line inputs: The AUDIOSYSTEM8.8 has 8 audio line inputs,
which can be configured as 4 stereo inputs or 8 mono inputs.

8. FM antenna: Connect the FM antenna wire here. When you
want to connect the input to an antenna or cable distribution
network, you need to connect through a galvanic separation
transformer designed for FM signals. We advise you to always
use a separation transformer to connect to a cable distribution
network because otherwise it may lead to unpredictable
behavior and even system damage.
9. Network cable connector: connect to a network,
AUDIOSYSTEM8.8 supports DHCP and DNS. A connection with
the device can be established through any web browser.
10. Emergency / Mute all: Contact closure for emergency mute on
all zones.
