Crestron Avia AMPI-8075 Dimensional drawing

DO GUIDE
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 amplier 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
Speakers are bridged with the 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: Only 8 ohm speakers can be bridged.
Fuse Replacement
If the amplier 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:
1. Disconnect power to the amplier.
2. Use a at-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.
CAUTION: Use the specied type of fuse only. Failure to do so may cause damage to the amplier.
NOTE: One spare fuse is included.
5. Insert the fuse holder into the amplier.
6. Push in the fuse holder with a at head screwdriver. While pushing in the fuse holder, turn the screwdriver clockwise until the fuse holder sets into place.
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 amplier.
AMP(I)-8075/AMP(I)-8150
AviaTM 8-Channel Commercial Ampliers
The Avia™ AMP-8075, AMPI-8075, AMP-8150, and AMPI-8150 feature similar operation. For simplicity within this guide, the term “amplier” is used for all
models except where noted.
DO Install the Device
These devices occupy 1U of rack space. Using a #1 or #2 Phillips screwdriver, attach the included rack ears to the device, and then mount the device into the
rack using eight mounting screws (not included).
DO Connect the Device
Make the necessary connections as called out in the following diagrams. Connect power last.
CAUTION: When connecting a Windows®7 or Windows 8 computer to the COMPUTER port for the rst 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).
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 specications
on the product web page.

DO Operate the Device
Apply Power
To turn the amplier and audio outputs on, move the POWER switch to |. To turn the amplier 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 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.
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.
As of the date of manufacture, these products have been tested and found to comply with specications for CE marking.

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) specied by the manufacturer.
•Reduced Airow: Installation of the equipment in a rack should be such that the amount of airow 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.”
