1. WARNINGS AND SAFETY
- To prevent fire or electric shock, do not expose this device to rain or moisture.
- Do not repair any parts inside the unit, but leave all repairs to qualified service personnel.
- As long as the mains cable of the machine is connected to a wall socket, the machine is live, even if the machine is switched off.
- Do not operate the device for a long time if the sound is distorted.
- Do not block the ventilation openings of the device.
2. DESCRIPTION
8-channel power amplifier is a perfect solution for those multi- room audio installations that require flexibility and quality audio. With its smooth appearance and versatility, this well-constructed amplifier has many features to enhance your installation and can be customized to fit any system.
Features include: individual input sensitivity control for each channel, line input for each channel and BUS A and BUS B source inputs and outputs, bridging between channels, in and out triggers. The specially designed digital chip set will minimize unwanted heat build-up to ensure the high-quality audio reproduction and longevity of the amplifier.
3. GENERAL INFORMATION & FEATURES
3.1 FRONT PANEL
-
POWER SWITCH
This is used to turn the unit on or off. -
LED INDICATORS
There is one LED indicator for the power and each zone.
Note: If a fault occurs within a particular zone, the led changes to red. If the fault remains, the corresponding led remains red and you must power cycle off and on to clear the fault. If the fault is momentary, then the zone led changes to red and then switches to solid white after a few seconds. Once all zones are cleared of faults the front lad’s will turn white as long as they are active.
3.2 REAR PANEL
On/Auto/Trigger Switch:
-
ON MODE
The corresponding zone always at “ON” mode, the amplifier will work when the zone receiving audio signal. If the zone detecting no problem, the LED lights will be white ; if the zone detecting some problems, the LED lights will be red. -
AUTO MODE
The inputs on the amplifier will detect an audio source and turn on when a source is present; after approximately 15 minutes without an audio source the amplifier will go into standby mode. After entering sleep mode there will be a 2-3
second power cycle period from sleep mode to play an audio signal. All zones at« AUTO » then the amplifier can be in standby if no signal 15 minutes. -
TRIGGER MODE
The amplifier will only turn on and off when using the 12v input and/or output. There will be a 2-3 second power cycle period from time power is applied to the trigger to play an audio signal. For general use it is recommended the amplifier be left in the “AUTO” -position. -
BUS A & B INPUTS
There are “right” and “left” RCA style connectors labeled as “ti:’ & “B”. These inputs are used for sending a single audio source (i.e. CD, Tuner, MP3 etc.) to more than one zone. For using this feature correctly, see “Connecting the Amplifier” later in this manual. -
BUS A & B OUTPUTS
There are “right” and “left” labeled as “A” & “B”. These outputs are used to loop the audio source that is connected to the “BUS INPUTS” out to a second Art Sound AMP850. -
INDIVIDUAL ZONE LINE INPUTS
These RCA style input connectors are the audio inputs for each individual channel of the amplifier. These inputs are to have audio sources dedicated to a single channel or zone on the amplifier. We suggest using a good quality RCA audio cable for best performance. The RCA inputs are labeled “Left” and “Right”. -
BRIDGE/NORMAL
This is used to switch each individual zone between stereo or bridged. -
BUS/LINE IN SWITCH This is used to indicate which input the individual channel or BUS will receive audio signal from the source.
-
GAIN ADJUSTMENT
This is an adjustment for the different voltage inputs with each source. Set the control so that the speakers are not distorting. -
POWER SUPPLY USB
5V/2A USB -
SPEAKER TERMINALS
These Phoenix type terminal connectors are used to connect the speaker to each zone. -
VOLTAGE SWITCH
Switch between 115V/230V depending on your location. -
3-CONDUCTOR AC CORD RECEPTACLE W/FUSE
A standard male receptacle that fits a 3-conductor power cord.
Note: the amplifier has a few seconds power cycle period before it will play an audio signal if either the auto or trigger are selected. This is normal and required to comply with the eu < 0.5 Watt erp directive.
4. CONNECTING THE AMPLIFIER
Always turn off the power of your amplifier, processor/preamp and all
output/playback units before any connections are made. Before turning your
amplifier and preamp back on, make sure your source volume is turned all the
way down.
Remember the cooling issues mentioned earlier in this manual. Improper airflow
will reduce the life of the amplifier.
When deciding on the final location, keep in mind that there needs to be
adequate space behind the amp to fit the speaker cables and patch cables.
STEREO CONNECTION
Use a good quality RCA type audio cable. Connect a stereo RCA cable from your
audio source to one of the inputs (Bus A & B or line-in) on the back of the
amplifier. Repeat this for each channel and/or zone if using the line-in
inputs.
The Bridge/Normal switch should be in the nor mal stereo mode. Connect the
speaker cable coming from each pair of speakers to the “Speaker Output”
connector on the back of the amplifier. This connector is removable to make
connection easier. When connecting the cable to the connector, check for any
wire strands that might be sticking out of the connection terminal that might
cause a short circuit. These amplifiers are stable down to 4 ohms. The
impedance with the connected speakers should not be
lower than 4 ohms.
BRIDGED CONNECTION
The bridging mode is meant for a single speaker and high power application
such as Home Theatre. In the bridged mode the speakers should be 8 ohms
minimum. Make sure the amplifier power is OFF before making connections.
Connect the right and left outputs from the audio source to the left input of
the zone you are bridging. Repeat this for each zone you want in bridged mode.
The bridge/ normal switch should be in the bridged (BR) position. Make sure
the switch is in this mode only on the zones you want bridged.
Connect the speaker cables coming from one speaker to the “speaker output”
connector on the back of the amplifier.
For bridging, one speaker will connect to one connector. Make sure to follow
the labelling on the back of the amp where the speaker output connector is for
the bridged zone. The speaker output connector is removable to make connection
easier. When connecting the cable to the connector, check for any wire strands
that might be sticking out the connection terminal that might cause a short
circuit.
Repeat this for each channel and or zone. Then, on the zones you want to access one of the BUS sources, put the input switch into the appropriate setting A or B position. Proceed to connect the speaker cable to the amplifier as per the instruction the “Stereo Connection” section of this manual.
5. GENERAL MAINTENANCE AND SERVICE
The front panel is finished with a high-grade anodizing process to ensure that
it maintains a flawless appearance. Occasionally, you should wipe off any dust
build up with a damp, soft cloth.
Do not use any kind of cleaning solution or cleanser on these units. If for
some reason the amplifier needs to be repaired, please contact us immediately.
We will issue a return authorization number. This unit should not be shipped
back to elision without the ra#.
Do not attempt to open or dismantle this amplifier. This will void the warranty!
