SYMPHONIC

SYMPHONIC

The phono stage provides the vital conditioning needed for a signal coming from the stylus

of your turntable and hugely amplifies the signal before it is fed to your pre-amplifier.

Combining high performance and ease of use, the phono stage is an important component

in a system that utilises a turntable.

background

We want you to be confident using your new Chord Electronics product.

You are probably an audiophile with extensive knowledge of audio equipment.

However, you may not be!

So in the following section we explain a few basics to help you get started, or get you back

up to speed if you are a little rusty.

connecting your equipment

Chord amplifiers are supplied with and designed to be connected using balanced inputs.

The interconnecting cables you use will depend on the available input and output sockets

on your other equipment. We have installed unbalanced inputs on all Chord equipment,

thus enabling you to mix Chord Electronics and other manufacturer’s equipment.

Balanced inputs carry twice the strength of signal of unbalanced inputs and are able to be

fed down long lengths of cable with less deterioration of signal. They are also less prone to

interference than unbalanced inputs. Balanced inputs have three pins and use Neutric XLR

style connectors. Pin 1 is earth, pin 2 is positive and pin 3 is negative.

Unbalanced inputs use RCA phono connectors, which are gold plated with teflon high

performance dielectric insulators for optimum performance.

when setting up

To ensure that your Chord product works efficiently and safely, please pay particular

attention to the following issues.

ventilation

Your Chord product should have at least 5cm of clear space all around it to ensure a free

flow of air at all times. We do not recommend that you place your Chord product directly

on a carpet as this can damage the equipment through blocked ventilation.

mains lead and plug

All Chord equipment comes supplied with the correct mains lead and plug. This should be

used at all times.

if you need to fit a plug for UK/Europe

Connect the blue wire to the neutral terminal

Connect the brown wire to the live terminal

Connect the yellow/green wire to the earth terminal

if you need to fit a plug for US/Canada

Connect the white wire to the neutral terminal

Connect the black wire to the live terminal

Connect the green to the earth terminal

earthing issues in Europe

In some European countries a hum may occur if your processor is connected to mains

sockets that do not have an earth. If this is the case please ensure that:

1. Your equipment is connected via a multi-way mains block which contains an earth point

at each socket outlet. This is to ensure that the chassis metalwork of each item is

connected together.

2. We recommend that an earthing method for your building is implemented.

3. Use the connecting points on your Chord unit and connect to an available earth point.

safety warnings

It is important that your equipment is earthed at all times via its own mains lead. Failure to

do this may be hazardous. The power supply components within the units are designed to

be operated at lethal voltages and energy levels. Circuit designs that embody these

components conform with applicable safety requirements. Precautions must be taken to

prevent accidental contact with power-line potentials. Do not connect grounded test

equipment.

This unit complies with EN 50081-1 and IEC 801/2

mains connection

The mains connector of your Choral product is at the back of the unit. Plug the female end

(socket) of the mains cable into the power connector of your Choral product, and the male

end (plug) of the mains cable into mains wall socket or mains extension socket. The mains

connector type will differ slightly for each Choral product. This is due to the highly

compact nature of this range requiring differences in chassis metalwork for each product.

balanced outputs on the

SYMPHONIC

You need to connect the outputs on the back of your SYMPHONIC to a pre-amplifier,

which in turn will feed a signal to a power amplifier in order to drive your loudspeakers.

There is a pair of balanced XLR outputs, which will drive a 68Ωload.

connecting to your pre-amplifier

Use the XLR style output connectors to connect your SYMPHONIC to the XLR style input

connectors of your PRIMA or any other model of pre-amplifier. Ensure that you connect

the left output on the SYMPHONIC to your left input on your pre-amplifier. Also the right

output on the SYMPHONIC should be connected to the right input on your pre-amplifier.

You need to connect the outputs on the back of your SYMPHONIC to a pre-amplifier,

which in turn will feed a signal to a power amplifier in order to drive your loudspeakers.

All Chord equipment is designed to be used with balanced connections to maximise audio

signal quality. However there is also a pair of unbalanced outputs as well in case your pre-

amplifier does not have balanced inputs.

connecting to your pre-amplifier

Use the phono style output connectors to connect your SYMPHONIC to the phono style

input connectors of your pre-amplifier. Ensure that you connect the left output on the

SYMPHONIC to your left input on your pre-amplifier. Also the right output on the

SYMPHONIC should be connected to the right input on your pre-amplifier.

You need to connect the outputs on your turntable inputs of your SYMPHONIC phono

stage, which in turn will feed a signal to a pre-amplifier. The signal will then pass onto a

power amplifier in order to drive your loudspeakers. There is a pair of balanced XLR

inputs on your SYMPHONIC phono stage.

connecting to your phono stage

Use the XLR style input connectors to connect your SYMPHONIC to the XLR style output

connectors of your turntable. Ensure that you connect the left output of your turntable to

the left input on your SYMPHONIC. Also the right output on the turntable should be

connected to the right input on your SYMPHONIC.
