Install the Device
These devices occupy 1U of rack space.
To install the included rack ears:
1. Use a #1 Philips screwdriver to remove the three 1/4 in. screws shown below from each side of the front of the amplifier.
2. Using the 1/4 in. screws removed in the previous step, attach the included rack ears to the front of the amplifier as shown below.
To install the included rear mounting brackets:
1. Use a #1 Philips screwdriver to remove the screws from the rear of the amplifier as shown below.
2. Using the 1/4 in. screws removed in the previous step, attach the mounting brackets to the rear of the amplifier as shown below.
Then, mount the device into the rack using eight mounting screws (not included).

Connect the Device
Make the necessary connections as called out in the following diagrams. Connect power last.
CAUTIONS:
• When connecting a Windows® 7 or Windows 8 computer to the COMPUTER port for the first time, make sure the computer has a live
connection to the Internet. For more information, refer to Answer ID 5745 in the Online Help section of the Crestron website (support.
crestron.com).
• Keep the device unplugged until all of the input, network, and speaker wiring is complete.
• Check the speaker wires for shorts and frayed wiring around the SPEAKER OUTPUTS connectors.
NOTES:
• Ensure that the unit is properly grounded by connecting the chassis ground lug to an earth ground (building steel).
• To 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.

Speaker Connections
The speaker outputs can be wired conventionally, or they can be bridged to deliver higher power to a speaker. Refer to the following diagrams 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 levels, as continued exposure to high sound pressure levels can cause permanent hearing impairment or loss.
Conventional Wiring Bridged Wiring

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 and Output 8.
NOTE: The minimum load impedance for bridged channels is 8 ohms.

Fuse Replacement
If the amplifier does not power up when the 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 amplifier.
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.

NOTE: One spare fuse is included.
5. Insert the fuse holder into the amplifier.
6. Push in the fuse holder with a flat head screwdriver.
7. Push in the fuse holder a little further and turn the screwdriver clockwise until the fuse
holder locks in place.
8. Connect power to the amplifier.
Operate the Device
Apply Power
To turn the amplifier and audio outputs on, move the power switch (located next to the power
connector) to |. To turn the amplifier and audio outputs off, move the power switch to O. This will
also reset the unit.
When power is applied to the device, the PWR LED on the front panel operates with the following
behavior:
• Green - Normal operation
• Amber - Device is booting up
• Amber/Green (Cycling) - No network connection
Adjust the Signal Levels
Each channel has a corresponding input attenuator on the rear panel. Adjustments can be
made here to achieve the desired loudness in each zone. To adjust an input's level, turn the knob
clockwise to increase the signal level or counterclockwise to reduce the signal level.
Monitor Operation
Use the front panel's status indicators and VU level meters to monitor each speaker output.
LEDs in the STATUS section indicate the following for each output:
• Presence of a fault
• An overcurrent condition
• A DC offset condition
• Excessive operating temperature
• 70 volt operation (100 volt operation for AMPI-8075 and AMPI-8150)
LEDs in the VU section indicate each output's signal level 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 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 the
Crestron Toolbox™ software (Functions > Device Info > Cloud Services). For details, refer to the
Crestron Toolbox help file.
To connect the device to the Crestron XiO Cloud service:
• Access the Crestron XiO Cloud Service at https://portal.crestron.io.
• Register for a Crestron XiO Cloud account at www.crestron.com/xiocloud.
For detailed information about using the Crestron XiO Cloud service, refer to the Crestron XiO
Cloud Service User Guide (Doc. 8124) at www.crestron.com/manuals.

Rack Mounting Safety Precautions
• Elevated Operating Ambient Temperature: If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room
ambient temperature. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the
manufacturer.
• Reduced Airflow: Installation of the equipment in a rack should be such that the amount of airflow required for safe operation of the equipment is not compromised.
• Mechanical Loading: Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
• Circuit Overloading: Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent
protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
• Reliable Earthing: Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch
circuit (e.g., use of power strips).
Electrical Connection:
“This product must be connected to an earthed mains socket-outlet.”
• Finland: “Laite on liitettävä suojamaadoituskoskettimilla varustettuun pistorasiaan.”
• Norway: “Apparatet må tilkoples jordet stikkontakt.”
• Sweden: “Apparaten skall anslutas till jordat uttag.”
