PRIMA

pre-amplifier

PRIMA

The pre-amplifier is the control centre of your system. By connecting your audio sources to

it you can choose the source you want at any particular time and control it.

You can also adjust the balance and volume before the signal is sent to a power amplifier.

Your pre-amplifiers can be operated manually or via any Chord remote control

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 tobe connected using balanced inputs.Theinterconnecting

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 downlong

lengthsofcable with lessdeterioration ofsignal.Theyarealsolesspronetointerferencethan 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.

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 viaits own mains lead. Failure to

do this may be hazardous. The power supplycomponents 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-linepotentials. Do not connect grounded test equipment.

This unit complies with EN 5008 1-1 and IEC 80 1/2

Caution: The BLU employs a laser that emits both visible and invisible radiation.

Removal of the top cover or tampering with any of the enclosed electronics may result in

exposure to hazardous levels of laser radiation that could cause eye damage. To prevent

injury this product should be returned for qualified service to Chord Electronics Ltd.

There are no user serviceable parts within any Chord Electronics Choral

product. Unauthorised tampering or dismantling of this product will

invalidate the warranty and could cause injury

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.
