INTRODUCTION

Congratulations on your purchase of the Audio Note (UK) P2 SE Signature stereo

power amplifier.

It is a Pure Class A, Single Ended valve design, which preserves the entire musical

waveform as one ‘whole’, producing a level of performance that is radically superior

to the majority of current designs.

Part selection is optimized to realize the most neutral and realistic sonic reproduction.

Some of the superior quality components utilized in the P2 SE Signature include: -

Audio Note (UK) Copper foil capacitors used in the most critical areas.

Audio Note (UK) Tantalum resistors used in the most critical areas.

Custom designed output transformers, manufactured by Audio Note (UK).

These output transformers –one of the most critical areas of valve amplifier

design – allow the P2 SE Signature to produce impressively extended and

controlled bass.

The Signature transformers are our custom manufactured IHiB, C-Core copper

wound models, which are quite possibly the finest examples of output

transformers for this type of amplifier available in the World today.

The P2 SE Signature fulfills all Audio Note (UK) Level 2 criteria: -

Pure Class A Single Ended Pentode operation

Materials and component quality

P2 SE SIGNATURE STEREO POWER AMPLIFIER

Please take care when unpacking your P2 SE Signature stereo power amplifier.

Choose a clean, clear location to unpack your unit. Be aware that the amplifier is

quite heavy; before attempting to unpack or lift the unit, check the weight and if

necessary use more than one person so that it can be moved safely and easily.

We recommend that you retain and carefully store all of the original packing

materials, in case transportation / shipping is required at a later date.

Select a suitable location for the unit. This should be a dry, dust free and level area,

preferably shielded from direct sunlight and free from vibration. Also ensure that the

location is stable and capable of carrying the weight of the unit.

A suitable mains power outlet must be close to the location; power cords must not be

pulled or stretched tightly in an attempt to reach a wall socket. If the power cord will

not easily reach the socket, choose a closer location!

Please ensure that adequate ventilation for the unit is provided, and that airflow

through any ventilation slots in the unit is not restricted. We recommend a distance of

at least 30cm free space is maintained above the unit, and preferably it should be

sited in free space or on the top shelf of your equipment rack or table. Please also

remember that valve equipment operates at extremely high temperatures, so a

position that is inaccessible to any children or animals is essential.

UNPACKING AND INSTALLATION

Line inputs Being a stereo power amplifier, the P2 SE Signature is fitted with one

pair of single ended / RCA inputs. Looking from behind the amplifier,

they are located at bottom / right hand side of the rear panel. The

Black socket is for the Left channel, the Red socket is for the Right

channel. Connect the output from your preamplifier to these inputs.

Speakers Each channel is equipped with 3 colour coded binding posts for

connection to your speakers, located on the rear panel.

Looking from the front of the amplifier, the 3 binding posts on the left

are for the LEFT channel and the 3 binding posts on the right are for

the RIGHT channel. Additionally, each set of binding posts is marked

‘LEFT’ and ‘RIGHT’.

Connect the amplifier’s black speaker output binding post marked as

“0” to the black / negative terminal (also marked “ –“) on the speaker.

Connect the amplifier’s red speaker output binding post marked

“8 Ohm” to the red / positive terminal (also marked “ + “) on the

speaker. The other red speaker output binding post is marked

“4 Ohm” and may be used with 4 Ohm speakers. If you are uncertain

whether your speaker system is specified as 4 or 8 Ohm, try the

following test once all other connections are made and the amplifier is

operational. Compare the sound quality using a familiar recording with

the speakers connected to the 8 ohm connections and then the 4 Ohm

connections respectively. The selection that produces the best

frequency balance and maximum dynamics should be used.

Ground Post A ground post is provided for connection to those source components

that also use a separate ground terminal.

Mains The P2 SE Signature features an IEC 320 mains inlet socket. Use the

supplied mains cable to connect the unit to the local mains supply.

The mains fuse and a spare are located in the inlet socket fuse

drawer.

Special Note –Make sure that all connectionsare tight and clean. For

best results use good quality audio interconnects. Although it is

perfectly acceptable to use cables manufactured by other companies,

for best results and performance, we recommend our own Audio Note

(UK) range of interconnects and loudspeaker cables. For further

information, please consult your nearest Audio Note (UK) dealer, or

alternatively please feel free to contact us directly.

CONNECTION

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.
