INTRODUCTION

Congratulations on your purchase of the Audio Note (UK) CONQUEROR Silver

Signature Low Gain stereo power amplifier.

It is a Pure Class A Singled Ended valve amplifier that uses the highly regarded 300B

triode valve, producing a level of performance that is radically superior to the vast

majority of current designs.

It has been specifically engineered for sonic performance rather than technical

specification, and fulfills all Audio Note (UK) Level 3 criteria: -

Pure Class A operation

Zero Negative Feedback

Single Ended Output Stage

Valve Rectification

Directly Heated Triode operation

The Silver Signature version builds upon the already superb performance of the

standard CONQUEROR, and features the following additions: -

Audio Note (UK) Copper Foil signal capacitors

Audio Note (UK) Tantalum film resistors

Audio Note (UK) IHiB Double C-core output transformers

Please take care when unpacking your CONQUEROR Silver Signature Low Gain

stereo power amplifier. Choose a clean, clear location to unpack your unit. Be aware

that the amplifier is very 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 20cm 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.

CONQUEROR SILVER SIGNATURE LOW GAIN

UNPACKING AND INSTALLATION

The amplifier is shipped without its valve compliment installed. It is necessary to

install the valves before operation.

It is essential that the valves are installed correctly or serious damage that is not

covered by the warranty will result. We recommend that your dealer perform

this procedure for you if you are in any way unsure.

FIRSTLY, ENSURE THAT THE AMPLIFIER IS NOT CONNECTED TO A MAINS

ELECTRICAL SUPPLY, AND THAT THE POWER CORD IS NOT CONNECTED TO

THE AMPLIFIER.

Now remove the valves that are packed inside the amplifier and carefully unwrap

them. Also inspect the amplifier to check that nothing has become damaged or

dislodged during transit.

2 x 300B output valves

2 x 6J5 input stage valves

1 x 5U4G rectifier valve

Once again, please understand that it is absolutely vital these valves are fitted

correctly.

Looking from the front of the amplifier install the 300B valves first. Inspect a 300B

valve base and you will notice that two of the pins are larger than the other two; this

is to help ensure that the valve can only be inserted one way.

Now examine the two large apertures located in the top plate of the amplifier,

between the smaller front valve base apertures and the large, black, square

transformer cover; you will notice that two of the four holes in each aperture are

larger than the others. Line up the large pins on the base of the 300B valve and the

large holes in each valve base, and with gentle but firm pressure insert the valve into

its socket.

Next, examine the 6J5 input stage valves. You will see that there is a rib on the

central pin of each valve, which ensures that it can only be inserted into the valve

base correctly. Locate this rib and align with the corresponding aperture in the centre

of the valve base, located in the top plate at the front / centre of the amplifier. With

gentle but firm pressure,insert the valve.

Next, examine the remaining 5U4G rectifier valve. You will see that there is a rib on

the central pin of the valve, which ensures that it can only be inserted into the valve

base correctly. Locate this rib and align with the corresponding aperture in the centre

of the valve base, located in the top plate towards the rear of the amplifier, between

the two large, black, square transformer covers. With gentle but firm pressure,insert

the valve.

Check one more time that all of the 5 valves are correctly fitted!

VALVE INSTALLATION

Line inputs Being a stereo power amplifier, the CONQUEROR Silver Signature

Low Gain is fitted with one pair of single ended / RCA inputs. Looking

from behind the amplifier, they are located at the right hand side of the

rear panel. The Black socket (top) is for the Left channel, the Red

socket (bottom) 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 rear of the amplifier, the 3 binding posts at the top

are for the left channel and the 3 binding posts at the bottom are for

the right channel.

Connect the amplifiers black speaker output binding post marked as

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

Connect the amplifiers 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.

Mains The CONQUEROR Silver Signature Low Gain uses 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 CONQUEROR Silver

Signature Low Gain; 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 rocker switch located on the rear top right of the

back panel, just above mains inlet socket.

Bedding in The new amplifier requires about 100 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 6000 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.
