To install the included rear mounting brackets:
1. Use a #1 Phillips screwdriver to remove the four screws from the rear
of the amplifier as shown in the following illustration.
2. Use the four screws removed in the previous step to attach the
mounting brackets to the rear of the amplifier.
Then mount the device into the rack using four rack mounting screws (not
included).
Connect the Device
Connect the device as called out in the following illustrations. Connect
power last.
CAUTIONS:
lKeep the device unplugged until all of the input, network, and
speaker wiring is complete.
lCheck the speaker cables for shorts and frayed wiring around the
SPEAKER OUTPUTS connectors.
NOTES:
lEnsure the unit is properly grounded by connecting the chassis
ground lug to an earth ground (building steel).
lTo prevent overheating, do not operate this product in an area that
exceeds the environmental temperature range listed in the table of
specifications on the product web page. Fans provide side-to-side
airflow for cooling. Do not block the ventilation holes.

Line Input Connection
If an unbalanced connection from a line input is required, use a jumper
between the negative (-) and ground (G) terminals.
Speaker Connections
The speaker outputs can be wired conventionally or they can be bridged to
deliver higher power. Refer to the following illustrations when connecting
speakers.
WARNING: This amplifier is capable of delivering high power to the
loudspeakers. Please use caution and wear adequate hearing
protection if listening at high volume, as continued exposure to high
sound pressure levels can cause permanent hearing impairment or
loss.
Speakers are bridged with the Crestron Avia™ Audio tool, which can be
downloaded from www.crestron.com/software. The possible bridging
combinations are Output 1 & Output 2, Output 3 & Output 4,
Output 5 & Output 6, and Output 7 & Output 8.
NOTE: The minimum load impedance for bridged channels is 8 ohms.

Fuse Replacement
if the amplifier does not power up when power is turned on, the fuse may
need to be replaced. The fuse holder is located on the rear panel next to
the power switch. To replace the fuse:
1. Disconnect power to the amplifer.
2. Use a flat-head screwdriver to push in the fuse holder.
3. While pushing in the fuse holder, turn the screwdriver
counterclockwise until the fuse holder pops out.
4. Remove the fuse from the fuse holder and insert a new fuse.

Operate the Device
Apply Power
To turn the amplifier on, move the power switch (located next to the
power connector) to |. To turn the amplifier off, move the power switch to
O. This will also reset the device.
When power is applied to the device, the PWR LED on the front panel
operates with the following behavior:
lGreen - Normal operation
lAmber - Device is booting up
lAmber/Green (cycling) - No network connection
Adjust the Signal Levels
Each channel has an input attenuator on the rear panel. Use these to
adjust the loudness in each zone. To adjust the level of an input, turn the
knob clockwise to increase the signal level, or counterclockwise to reduce
the signal level.

Monitor Operation
Use the status indicators and VU meters on the front panel to monitor
each speaker output.
LEDs in the STATUS section indicate the following for each output:
lPresence of a fault
lAn overcurrent condition
lA DC offset condition
lExcessive operating temperature
l70 volt operation (100 volt operation for the AMPI-8075 and
AMPI-8150
LEDs in the VU section indicate the signal level of each output and
whether a clipping condition is present.
Reset the Device
Press RESET on the front panel to restart the device.
Connect to Crestron XiO Cloud
Service (Optional)
The Crestron XiO Cloud™ service allows supported Crestron devices
across an enterprise to be managed and configured from one central and
secure location in the cloud. Supported devices are preconfigured to
connect to the service. Use of the service requires a registered Crestron
XiO Cloud account.
NOTE: The device can be disconnected from the service using the
Cloud Services tab in Crestron Toolbox™ software (Functions > Device
Info > Cloud Services). For details, refer to the Crestron Toolbox help
