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

¥The unit has been dropped, mechanically damaged or treated

improperly.

¥The power cord or plug has been damaged.

¥Objects have fallen into the unit.

¥Liquid has been spilled into the unit.

¥The unit is not operating normally.

¥The device displays errors.

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

32dB

Input in dBFS + 32dB = Output in dBV

Example: -12dBFS →20dBV

2.5. PROTECTION CIRCUITS

The amplifier contains the following protection circuits to ensure safe operation under

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.
