Fuse Replacement
If the amplier 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 amplier.
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 specied type of fuse only. Failure to do so may cause damage to the amplier.
NOTE: One spare fuse is included.
5. Insert the fuse holder into the amplier.
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 amplier.
DO Operate the Device
Apply Power
To turn the amplier and audio outputs on, move the POWER switch to |. To turn the amplier 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.

CAUTION:Changes or modications not expressly approved by the manufacturer responsible for compliance could void the user’s authority to operate the equipment.
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.
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.

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) specied by the manufacturer.
• Reduced Airow: Installation of the equipment in a rack should be such that the amount of airow 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.”
