CAUTION: To reduce the risk of electric shock, do not remove cover (or back).
No user serviceable parts inside. Refer servicing to qualified service personnel.
WARNING: To reduce the risk of fire or electric shock, do not expose the amplifier to rain or moisture.
The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert
the user to the presence of uninsulated ‘dangerous voltage’ within the product’s enclosure that
may be of sucient magnitude to constitute a risk of electric shock to persons.
The amplifier should be serviced by qualified service personnelSafety instructions

1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Clean the amplifier only with a dry, lint-free cloth. For more thorough cleaning, unplug
the amplifier from the mains supply and go over it lightly with a damp, lint-free cloth.
Do not use any type of chemical solvents or other cleaning products for cleaning.
6. Do not install near any heat sources such as radiators, heat registers, stoves, or other
apparatus (including amplifiers) that produce heat.
7. Protect the power cord from being walked on or pinched particularly at plugs,
convenience receptacles, and the point where they exit from the apparatus.
8. Unplug the amplifier during lightning storms or when unused for long periods
of time.
9. Do not defeat the safety purpose of the polarized or grounding-type plug.
10. Place the amplifier horizontally and on a suitable table or rack.
11. Refer all servicing to qualified service personnel.
12. Servicing is required when the amplifier has been damaged in any way, such as
when the powersupply cord or plug is damaged, liquid has been spilled or objects
have fallen into the amplifier, the amplifier has been exposed to rain or moisture,
does not operate normally, or has been dropped.
The amplifier should be serviced by qualified service personnel when:
A. the power-supply cord or the plug has been damaged, or
B. objects have fallen, or liquid has been spilled into the amplifier, or
C. the amplifier has been exposed to rain, or
D. the amplifier does not appear to operate normally or exhibits a marked
change in performance, or
E. the amplifier has been dropped or the enclosure damaged.
1. WARNING - Take care that objects do not fall and liquids are not spilled into the
enclosure through any openings. The amplifier shall not be exposed to dripping or
splashing. Liquid-filled objects such as vases should not be placed on the amplifier.
2. The amplifier has been designed for use in moderate climates and in
domestic situations.
3. Only connect the amplifier to a power supply of the type described in the operating
instructions or as marked on the amplifier. The primary method of isolating the
amplifier from the mains supply is to remove the mains plug.
The amplifier must be installed in a manner that makes disconnection possible.
4. If an abnormal smell or smoke is detected from the amplifier,
turn the power o immediately and unplug the amplifier from the wall outlet.
Contact your dealer and do not reconnect the amplifier.
Front panel
The balanced/unbalanced selector, is not a true input selector - it only
optimises the amplifier for the selected mode of operation. The amplifier will
play, with the incorrect mode selected.
Note: The button can move diagonally also, but it is only intended to move
up/down and left/right.
STANDBY/POWER INDICATORS
When the amplifier is in standby mode, the only light showing on the
amplifier will be a dim LED light above the rocker button. With the amp on,
the brightness of the LED increases, and the right and left sides of the
display window will be diusely lit. During the power-on phase, green
diuse lights flash on the sides as well.
INPUT INDICATORS
The two RCA and XLR indicators show which input is selected.
CURRENT INDICATORS
If one or both of the current indicators switch on, too much current is
running through the output stage. This usually occurs because of a short
circuit in the speaker wiring. When the error is detected, the speaker
output(s) will be switched o, and you have to switch the amplifier o and
back on, to re-enable normal operation. Before you switch the amp back
on, make sure that there are no wiring errors. The error could be strands
of wire from the speaker cable touching each other or the metalwork of the
amplifier. If the indicators come on again after power cycling the amplifier,
and even with speakers disconnected, the amplifier has been damaged, and
will need servicing.
DC-OUT INDICATORS
If one or both of the DC-out indicators switch on, DC is present on the
output(s) of the amplifier. When this occurs, the speaker output(s) are
disabled to protect the speakers. If music is playing, the sound will be
distorted and low in level. The DC could come from the preamp or a signal
source. Try switching the amplifier o and back on. If the DC error is still
present, try switching the amplifier o, disconnect the input cable(s),
and switch the amp back on. If the DC error persists, with input cables
disconnected, the error is in the power amplifier. Otherwise the error is in
the preamplifier or the signal source.

FRONT ROCKER BUTTON
The button has four functions. To switch the amplifier on, press the top of
the button. To switch it o, press the bottom.
To select the balanced input, press the right side of the button, and press
the left side to select the unbalanced input.

Front panel functions
The DC indicators may switch on during power up, and then switch o again
after a couple of seconds. This is just the DC levels of the preamplifier or
power amplifier that take a bit of time to stabilise. This causes no problems,
and is not an error.
TEMP INDICATORS
If one or both of the temp indicators switch on, the temperature inside the
amplifier is reaching critical levels. This can occur if the ambient temperature
is too high and/or the amplifier has been delivering large amounts of power
into low impedance speakers. When the indicators first switch on, it is only a
warning. If the temperature drops again, the indicators will switch o. If the
temperature continues to rise however, the amplifier will switch o. In that
case, you have to let the amplifier cool o for some time, and then switch it
o and on using the main power switch on the back panel.

SPEAKER TERMINALS
The P-300 amplifier accepts speaker cables terminated with spade connec-
tors and 4mm banana plugs.
To connect speaker wires terminated with spades, loosen the isolation knob
and insert the spade between the isolator and copper terminal. Tighten the
isolation knob to secure the spade.
To connect speaker wires terminated with banana plugs, insert the banana
plug into the centre hole of the copper terminal.
The positive speaker terminal is white, and the negative is black.
LINE INPUTS
The P-300 amplifier is equipped with an unbalanced (RCA) and a balanced
(XLR) line input. Only one input type can be used at a time, and no cable
can be connected to the unused input.
XLR pin-out:
1: Ground
2: + (non-inverting)
3: - (inverting)
TRIGGER INPUT
Connect the trigger input to the trigger output of the preamp, to get remote
controlled power on/o switching. When the amplifier is in standby mode, it
can be switched on by applying 5-12VDC to the trigger input. The amplifier
switches o again, when the trigger voltage is removed.
RS-232
The RS-232 connection is used for firmware updates, or for remote control.
POWER ON/OFF SWITCH
Toggle the switch to turn the amplifier fully on or fully o.
When the amplifier is in standby mode, the power consumption is less than
0.5 watt. When the amplifier is fully on and there is no applied signal, the
power consumption is less than 100 watts.
POWER INLET (CAUTION!)
The P-300 amplifier accepts mains voltages from 100 to 240VAC 50-60Hz.
The power inlet accepts power cables with an IEC 60320-C13 female
connector.
To ensure the best performance, please consult your Aavik Acoustics dealer
for a suitable mains cable.
