Keep the device away from dust, moisture, water and other liquids! In such
case, the further usage is prohibited!
The amplifier has a relatively high output power and possibly can be a
hazard for people and speakers. Pay particular attention to any defective
set volume.
Do not touch the housing of the device, during operation. The surfaces can
be hot. After switching off the device, wait 30 minutes till touching the
device.

In the following cases it is necessary to return the amplifier for
examination to the manufacturer. Contact details can be found on our
website: www.innosonix.de

1.1. INSTALLATION INSTRUCTIONS
All devices can be installed in a 19-inch rack. Screw the devices at each of the two
Mounting holes of the mounting bracket on the front. Use Screws with a sufficiently
large head diameter and lock washers.
We recommend mounting the unit cantilevered. The use of guide rails and bearing
surfaces can affect the convection.
1.2. VENTILATION AND COOLING
Built-in and 19-inch racks must be ventilated adequately. The passively cooled devices
must not be placed directly over each other since the housing is cooled by convection.
There must be at least 1U space under and above the unit.

2.3. AMPLIFIER
2.3.1. VOLTAGE, CURRENT AND POWER
This Unit uses full bridge Class-D amplifiers. Only by the extremely high efficiency of a
"switched" amplifier, it is possible to accommodate 32 channels in 2U.
Due to the H-Bridge concept used, all outputs are biased by half VCC which
is approximately 24V. So no common ground for outputs exist.
All outputs are internal bridged pairs, no external bridging is possible
¥Internal Operating Voltage 48V
¥Maximum voltage at the speaker terminal 94Vpp 33VRms
¥Maximum output current 15A peak

POWER DISTRIBUTION
¥The power supply can deliver 2000W continuous power. To ensure a
stable operation in overload situations, the MA32 involves an overall
power limiter. With an attack time of 100ms and a release of 3s the
limiter softly reduces the gain of all channels simultaneously not to
exceed the maximum available power. At 110V lines, a derating of 20%
must be considered.
¥The pulse power of 32*530W is buffered through 65.000uF of
capacitors and is certainly available as a short burst only.
¥An amplifier efficency of 85% can be expected.
¥All amplifiers are sourced by one powersupply.
¥Assuming a evenly distribution of load between all channels. The
MA32/D is able to give 50W continous sine power per channel. At 110V
line it is after all 40W.
¥Maximum continuous power output per channel is limited to 200W at 4
Ohms because of thermal reasons. (Continous power longer than 10
seconds). There is no limitation at 8 Ohm loads.
2.4. GAIN

Input in dBFS + 32dB = Output in dBV

all conditions.

Protection Function Description
Temperature An assembly consisting of 8 channels shuts down at 85¡C
heat sink temperature. The remaining 24 stay active. With a
Hysteresis of 25 ¡ C, i.e., at 60 ¡ C, the affected group turns
on again. Each MOSFET bridge on a module has a
shutdown threshold of 120 ¡ C. In this case, only two
channels are affected, and the other 30 remains active.
Direct Current If the polarity of the signal changes not for more than a
second, the affected channel switches off and restarts
again after a few seconds.
Short Circuit The affected channel is switched off when the maximum
current of 15A is exceeded. Recovery time is about two
seconds.
Low Impedance The amplifier works unconditionally stable at low
impedance as long as the maximum current is not
exceeded.
2.5.1. AMP CHIP / CHANNEL MAPPING
Every Amp Chip has two output channels. The assignment of Amp to Output channels is
in the table below.

32 input channels over Dante IP-Network.
Option D1 and D2 can be used independently
A DSP is a digital signal processing chain inside the FPGA that calculates the volume
control, filtering and limiting parameters on the selected Input Source. There are as
many DSP channels as amplifier outputs on the MAXX device. DSPs are "hardwired" to
the corresponding amplifier, e.g. DSP channel 1 supplies an amplifier that is wired to
CH1 Jack on the rear panel.
