Operation - Audio Note P1 Owner's Information

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 P1; 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.

OPERATION

Unlike most Stereo power amplifiers, the P1 is equipped with a
volume control. When in use with a preamplifier, set the P1
volume control so that the preamplifierʼs volume control is
operating in its optimum range, usually between the 9 oʼclock
and 3 oʼclock positions. This will usually result in the P1ʼs
volume control being set at roughly the 12 oʼclock position.
When using the P1 with a line level source, use the volume
control to set the desired listening level.
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.
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
SUPPLY BEFORE UNDERTAKING ANY CLEANING.
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.
