The amplifier is a device of protection class 1. Make sure that the protective
conductor (earth) is connected properly. A missing earth can lead to dangerous
voltages at the enclousure!
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.

1.2. INSTALLATION
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.
Figure 1. MAXX/LP² installation
We recommend mounting the unit cantilevered. The use of guide rails and bearing surfaces can
affect the convection. Make sure there is at least 1 RU between devices when FAN MODE is set
to PASSIVE. (See. VENTILATION AND COOLING)

1.3. VENTILATION AND COOLING
Built-in and 19-inch racks must be ventilated adequately.
1.3.1. PASSIVE COOLING
Passive Cooling is actived by setting the FAN MODE to PASSIVE. This Mode is recommended if
the amplifier is installed directly in an audience space or similar where no FAN noises are
acceptable. In all other situations, ACTIVE COOLING should be the preferred mode.
When a critical temperature is reached, all channels are shut down until a temperature sinks, and
itÕs safe to power on the channels again.
The devices must not be placed directly over each other since the housing is
cooled by convection. (see. RACK MOUNTING)
Figure 3. MAXX/LP² Convection
1.3.2. ACTIVE COOLING
The active cooling system inside the device creates front to back ventilation.

DANTE IP SETTINGS
To control and change IP Settings of DANTE, use the DEVICE page DANTE SETTINGS, or use in
Dante Device View.
CONTROL IP SETTINGS
There are several ways to change the IP of an Amplifier. See DISPLAY MENU to change on Display
Menu, DEVICE to change on Website or use the external software IDFM (see IP SETTINGS).
There are three different IP Types available:
Table 4. IP TYPES
TYPE DESCRIPTION
static set IP, SUBNET and GATEWAY manually
dhcp system tries to get a DHCP release, there is also an auto ip fallback, if no lease available
auto-ip force zeroconf IP, device will get an address with a 169.254/16 prefix (that is, 169.254.xxx.xxx)
HOSTNAME
With mDNS the device is also available with its hostname. With hostname AMP1 the local name
is AMP1.local. The Name can be used to call every network service, like a webbrowser,
http://AMP1.local.
There are several ways to change the Hostname of an Amplifier. See DEVICE to change on
Website or use the external software IDFM.
NETWORK SERVICES
¥ Full remote control via the website hosted on the device (see WEBSITE)
¥ REST-API, JSON based web service for integration in media control systems (see RESTful API)
¥ mDNS name resolution and servicediscovery (INFO HERE)
¥ syslog integration to send notifications to external syslog server (INFO HERE)

2.4.4. MADI (AES10) / AES3
MADI (Multichannel Audio Digital Interface) or AES10 is a standard that defines electrical
characteristics and the data format of an interface that carries multiple channels of digital audio.
There are two Coaxial Inputs available, which also can be used as AES3 Inputs, one optical input
and an optical output. On every Input the device supports 44.1kHz / 48kHz with 56 / 64 channels
and 88.2 kHz / 96kHz with 28 / 32 channels.
MADI Optical
To use the Optical MADI interface, a 1300nm multimode cable with SC connectors is required.
MADI Coaxial / AES3
The two BNC (75 Ohm) jacks are multifunctional inputs and can be used as AES10 MADI or AES3
interface.
To use the BNC input for AES3, a 110 to 75 Ohm impedance transformer like (NADITBNC-F) or
(NADITBNC-FX) is required.
Every AES3 input has an asynchronous samplerate converter enabled which can hanlde
samplerates from 32kHz - 192kHz.
