WARNING: To prevent bodily injury when mounting or servicing this unit in a rack, observe the following guidelines:
•• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
Speaker Connections
•• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.
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.
CAUTION: To prevent equipment damage, use only the Crestron® rack ears provided for this device.
NOTE: Although amplifiers can be installed in a rack without space between them, it is recommended to add a space between devices to allow ease of
access to the rear panel connections.
Placing onto a Flat Surface
WARNING: This amplifier is capable of delivering high power to the loudspeakers. Please use caution and adequate ear protection if listening to content
at high volume levels, as continued exposure to high sound pressure levels can cause permanent hearing impairment or loss.
Conventional Wiring
Bridged Wiring
When placing the device onto a flat surface or stacking it with other equipment, attach the included feet near the corners on the underside of the device.
DO Connect the Device
Make the necessary connections as called out in the following diagrams. Connect power last.
CAUTION: Keep the device unplugged until all of the input, network, and speaker wiring is complete.
CAUTION: Check the speaker wires for shorts and frayed wiring around the SPEAKER OUTPUTS connectors.
NOTE: Ensure the unit is properly grounded by connecting the chassis ground lug to an earth ground (building steel).
NOTE: To prevent overheating, do not operate this product in an area that exceeds the environmental temperature range listed in the table of
Speakers are bridged with the Avia Audio tool, which can be downloaded from The possible bridging combinations are
Output 1 & Output 2, Output 3 & Output 4, Output 5 & Output 6, and Output 7 & Output 8.
Front Panel
NOTE: Only 8 ohm speakers can be bridged.

Fuse Replacement
DO Operate the Device
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, perform the following procedure:
Apply Power
1.Disconnect power to the amplifier.
To turn the amplifier and audio outputs on, move the POWER switch to |. To turn the amplifier and audio outputs off, move the POWER switch to O. This
will also reset the unit.
2.Use a flat head screwdriver to push in the fuse holder.
When power is applied to the device, the PWR LED on the front panel operates with the following behavior:
3.While pushing in the fuse holder, turn the screwdriver counterclockwise until the fuse holder pops out.
•• Green - Normal operation
4.Remove the fuse from the fuse holder and insert a new fuse.
•• Amber - Device is booting up

•• Amber/Green (Cycling) - No network connection
Adjust the Signal Levels
Each input has its own signal level control that can be adjusted as necessary to balance the sound between inputs or to accommodate different audio
sources. To adjust an input’s level, turn the knob clockwise to increase the signal level or turn the knob counterclockwise to reduce the signal level.
Monitor Operation
Use the front panel’s status indicators and VU meters to monitor each speaker output.
CAUTION: Use the specified type of fuse only. Failure to do so may cause damage to the amplifier.
LEDs in the STATUS section indicate the following for each output:
•• Presence of a fault
NOTE: One spare fuse is included.
•• An overcurrent condition
5.Insert the fuse holder into the amplifier.
•• A DC offset condition
6.Push in the fuse holder with a flat head screwdriver. While pushing in the fuse holder, turn the screwdriver clockwise until the fuse holder sets into
•• Excessive operating temperature
•• 70 volt operation (100 volt operation for AMPI-8075 and AMPI-8150)
7.Push in the fuse holder a little further and turn the screwdriver clockwise until the fuse holder locks in place.
LEDs in the VU section indicate each output’s signal level and whether a clipping condition is present.
8.Connect power to the amplifier.
Reset the Device
Press RESET on the front panel to restart the device.

Rack Mounting Safety Precautions
Federal Communications Commission (FCC) Compliance Statement
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
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).
CAUTION: Changes or modifications not expressly approved by the manufacturer responsible for compliance could void the user’s authority to operate the equipment.
Electrical Connection
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
“This product must be connected to an earthed mains socket-outlet.”
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference
by one or more of the following measures:
•• Reorient or relocate the receiving antenna.
•• Increase the separation between the equipment and receiver.
•• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
•• Consult the dealer or an experienced radio/TV technician for help.
