Audio Note P2 SE Signature - Manual (Page 9)

Once all the connections are completed and checked, ensure that the volume control
of your preamplifier / source is at the minimum setting.
Turn on all components in the signal chain BEFORE the P2 SE Signature; it should
always be the LAST component to be switched ON, and the FIRST to be switched
OFF.
Turn on the amplifier by using the rotary switch located on the right of the front panel.
The red front panel light should now be lit. The amplifier requires approximately 45
seconds to initialize before it is ready for operation.
Volume Control
Unlike most Stereo power amplifiers, the P2 SE Signature is
equipped with a volume control. When in use with a
preamplifier, set the P2 SE Signature volume control so that
the preamplifier’s volume control is operating in its optimum
range, usually between the 9 o’clock and 3 o’clock positions.
This will usually result in the P2 SE’s volume control being set
at roughly the 12 o’clock position.
When using the P2 SE Signature with a line level source, use
the volume control to set the desired listening level.
Bedding in
The new amplifier requires about 200 hours of initial use (called
“bedding in”) before the circuitry becomes stable and optimum
performance is realized.
As the amplifier “beds in” the sound will become increasingly
smoother, detailed and open.
Once the amplifier has “bedded in” a warm up time of
approximately 30 to 45 minutes is required each time the
amplifier is switched on before optimum sonic performance is
reached.
Cleaning
No special maintenance is required for the amplifier. Use a
soft, clean lint free cloth to remove any surface marks from the
casework. For finger marks / grease, use a soft, clean lint free
cloth, lightly moistened with a solution of warm water and mild
detergent. Do not use any alcohol or solvent based cleaning
products, as they may damage the finish of the amplifier.
ENSURE THAT THE AMPLIFIER IS SWITCHED OFF AND
DISCONNECTED
FROM THE MAINS ELECTRICITY
SUPPLY BEFORE UNDERTAKING ANY CLEANING.
Valve Life
The valves supplied with your amplifier should provide
approximately 4000 hours of operation. They are specially
selected by us, and should only be replaced with matched
pairs. Please consult your Audio Note (UK) dealer should your
valves need replacing.
