Audio Note OTO Valve Integrated Amplifier

OTO LINE 

It is a Push Pull, Pure Class A valve design, offering an outstanding level of

performance and value.

It has been specifically engineered for sonic performance rather than technical

specification, and fulfills all Audio Note (UK) Level 1 criteria: -

Pure Class A Push-Pull Pentode operation

Materials and component quality

A high gain power amplifier stage is used consisting of an ECC83 dual triode acting

as an anode follower for the first stage, the output of which is applied to a second

anode follower which feeds the parallel connected EL84 output valves. This

arrangement allows for a passive line stage / volume control circuit to be

incorporated into the design.

The output transformers are custom designed and manufactured by Audio Note (UK),

and are of the highest possible quality.

The power supply is a multi element design, ensuring precise operation of each

circuit stage, whilst a DC supply feeds the low level valve filaments.

 Line inputs

Four line inputs are available for connection, labeled CD1, CD2, Tuner

and Aux. Any standard ʻline levelʼ source can be connected to these inputs.

Connect the ʻRec-Outʼ or ʻLine Outʼ sockets on your recording device

to the ʻTape Inʼ sockets of the OTO, and the ʻTape Outʼ sockets to the

ʻRec-Inʼ or ʻLine Inʼ sockets of your recording device.

Ground Post

A ground post is provided for connection to those source components

that also use a separate ground terminal.

Speakers

Each channel is equipped with 3 colour coded binding posts for

connection to your speakers.

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

are for the left channel and the 3 binding posts to the right 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.

Input Selector

Turn the selector to the source you wish to listen to.

 Source / Tape

This allows you to switch between the selected source input

and the output of your recording device.

 Volume Control

This control adjusts the listening level, or loudness. Set as

desired!

Balance Control

This control adjusts the relative left/right levels. Use this control

if necessary to equalize the loudness from each speaker.

Bending 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 8000 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.
