LOUDSPEAKERS

WARNING - Speaker Terminals

In order to comply with BSEN 60-

065 safety regulations

，

the 4mm banana

plug holes have been fitted with plastic

blanking pieces. Removal of these will

invalidate any safety approval of this

To get the best from your FX2 for

a realistic soundstage and full dynamic

range

，

use it with loudspeakers of a

reasonable efficiency. Anaverage rating

for a loudspeaker these days is about

87dB. This should mean that for an

input of 1 watt

，

measured at 1 metre

distance

，

the sound output will be 87dB.

This is actually a reasonably loud sound

，

and much daily listening will not use

much more power than this. Note that

changing to a pair of speakers with a

rating of 90dB is equivalent to doubling

the power of your amplifie

To give

some comparisons

，

a full concert orches-

tra will touch 105 to 11

dBfor short

periods during a crescendo. Concorde at

take off measures over 130dB

，

which is

the threshold of pain

，

and positively

dangerous.

FOR THE BEST RESULTS

‘

We strongly recommend that you

use the F2 pre-amplifier manufactured

by Musical Fidelity.

This is designed for perfect electri-

cal and sonic compatibility with the

FX2. When paired

，

they produce truly

extraordinary results which afford an

unprecedented level of musical commu-

nication

，

articulation and dynamics.

One of the design aims of the FX2

was that it should be relatively insensi-

tive to the effects of interconnect cables.

Although it is important that you use low

impedance

，

low capacitance cables

，

the

CONNECTIONS

exact make and model are not too impor-

tan

Similarly

，

a lot of fuss is made

about different types of plugs and sock-

ets; once again

，

the FX2is very insensi-

tive to these differences.

A large amount of time

，

effort

，

money and energy has been expended to

ensure that your FX2will produce

optimal results with almost any cables or

connectors. We hope that this makes

ymπ installation and listening easier and

more enjoyable.

CONNECTIONS

All connections should be made

with the power OFF.

The FX2has inputs for unbalanced

RCA type phono plugs.

The mains connector is a standard

IEC type. Do not try to use any other

type of mains lead.

STEREO / MONO OPERATION

The stereo / mono switch situated

on the back panel of the unit allows the

FX2to be operated as a monobloc thus

allowing you to use two FX2’s as a

stereo pai

One unit would then drive

the left speaker whilst the other drives

the righ

Using two FX2

’

s in this way

gives a noticeable increase in dynamic

and imaging properties. When mono

’

you may use either of the two phono

inputs and either of the two loudspeaker

outputs to make your connections to

each monobloc.

The LED indicators on the front

panel show which mode is currently

selected.
