1.#General#Description#
The Absolare Integrated Amplifier is a hybrid design single chassis stereo amplifier.
The ube input section is inspired by the Absolare Preamplifier and the output section
is all solid-state, dual mono construction. Both transformer balanced (XLR) and
unbalanced (RCA) input versions are available.
2.#Safety#Issues#and#Warnings#
- Ensure the voltage setting of the unit matches the voltage of the available AC
power..Operating voltage is fixed and must only be changed by an authorized
service agent.
- Do not touch tubes while operating. Tubes are extremely hot devices and also
contain very high voltages.
- There are no user serviceable parts inside the units. Do not open bottom covers.
- Do not short circuit the speaker terminals. The output is protected for short circuits
but speaker damage may occur from electrical pulses when the connectors touch
each other.

3.#Unpacking#and#Placement#
After opening the top cover of the box, remove the upper layer of hard foam material.
You can then lift the units from the box using the cloth underneath the chassis.
The unit may become very hot during operation. You should always place the unit on
feet and leave at least 2 inches (5 cm) clearance above both units to allow sufficient
ventilation.
Feet can affect the sound quality significantly. Feet should be placed directly under
the aluminum base plate, not in contact with the MDF/leather plate. There are three
areas where the aluminum base plate is exposed through openings in the bottom
MDF/leather plate. These areas are where the feet should be placed. You can use
either three or four feet. Adjusting their position will also affect the sound to varying
degrees, depending on the type of rack, location or interaction with other equipment.
For most situations the arrangement as shown in the diagram below is a good
starting point.

4.#Installing#the#Tubes#
There are two 12AU7 (ECC82) tubes in the input stage. Do not remove the tube
while the unit is operating.
12AU7 / ECC82 tubes have one missing pin acting as a correct positioning key.
Align missing pin with the missing hole in the tube socket while inserting.

5.#Connecting#the#Cables#
5.1.$Power$cables$
AC power input is via a standard IEC socket. Operating voltage must only be
changed by an authorized service agent.
The quality of the power cable used will affect the sound quality.
5.2.$Signal$Cables$
You can connect 4 unbalanced or 4 balanced source devices at the same time. The
selector knob on the left hand side switches between the input channels. Input is
single-ended RCA or transformer balanced XLR depending on the version.
5.3.$Speaker$Cables$
Speaker binding posts can handle spade lugs, banana plugs or bare wire.
Polyethylene knobs are chosen instead of metal ones to reduce extra conductor
mass and eddy currents. Do not overtighten the binding posts. The higher friction of
polyethylene will secure the speaker cables.
You can connect any speaker with 4 ohm impedance or above.
CAUTION: Negative (black) speaker terminals are not at ground level electrically. Do
not connect them to chassis ground or each other in any way. This unit is not
bridgeable.

6.#Operating#the#Unit#
6.1.$General$Operation$
Before turning on the unit be sure that all tubes are installed correctly and all cables
are connected correctly.
After turning on, the power indicator LED on the front plate will start to blink. Sound
will only be audible after all capacitors inside are charged and internal voltages are
stabilized (after that the indicator LED starts to illuminate continuously).
Absolare Integrated Amplifier will be ready to operate approx. 40 seconds after
turning on the power, but attaining full performance may take 15 to 30 minutes.
6.2.$Setting$the$Volume$Level$
Absolare Integrated Amplifier has a 64 step motorized attenuator with IR remote
control. You can either set the volume level by turning the right hand knob or via the
remote control. Operating angle of remote control unit is about 45°.

7.#Troubleshooting#and#Maintenance#
Surface of the unit is dirty.
- Clean with a slightly damp cloth.
No power light.
- Check AC line voltage.
- Check the main fuse.
Remote control is not working.
- Check the angle, see section (6.2).
- Check the batteries of the remote
control unit.
Power light is on, tube heaters are
glowing, but no sound.
- Check the input cables , speaker cables
and source.
- Check input selector.
- Tube(s) are defective.
Noise / hum in the sound.
- Check grounding of power, input cables
and source.
If the problem is persistent, contact your nearest ABSOLARE dealer.
