P1 SE SIGNATURE STEREO POWER AMPLIFIER

Congratulations on your purchase of the Audio Note (UK) P1 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 P1 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 P1 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 P1 SE Signature fulfills all Audio Note (UK) Level 2 criteria: -

Pure Class A Single Ended Pentode operation

Materials and component quality

UNPACKING AND INSTALLATION

Please take care when unpacking your P1 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.

CONNECTION

Line inputs Being a stereo power amplifier, the P1 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 P1 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 connections are 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.

OPERATION

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 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 P1 SE Signature is equipped with a volume control. When in use with a preamplifier, set the P1 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 P1 SE’s volume control being set at roughly the 12 o’clock position.

When using the P1 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.
