CONNECTIONS
FOR THE BEST RESULTS
We strongly recommend that you use the FX2 power amplifier manufactured by
Musical Fidelity.
Thi s is designed for perfect electrical and sonic compatibility with the F2. When
paired ， they produce truly extraordinary results which afford an unprecedented level
of musical communication ， articulation and dynamics.
One ofthe design aims of the F2 was that it should be relatively insensitive to the
effects of interconnect cables. Although it is important that you use low impedance ，
low capacitance cables ， the exact make and model are not too importan t. Similarly ， a
lot of fuss is made about different types of plugs and sockets; once again ， the F2 is
very insensitive to these differences
A large amount of time ， effort ， money and energy has been expended to ensure
that your F2 will produce optimal results with almost any cables or connectors. We
hope that this makes your installation and listening easier and more enjoyable.
CONNECTIONS
All connections should be made with the power OFF.
The F2 has 6 inputs ， Phono Aux ， CD ， CDV ， Tuner and two Tape decks.
The F2 has separate Source and Output to Tape 2 selector knobs. This is a very
flexible arrangement which allows you to listen to one source whilst recording an-
othe r. The source selector is used to select which input you wish to listen to ， this
source will also be sent to the Tape 1 outputs for recording on Tape 1. The Output to
Tape 2 selector operates independently and selects which source is sent to the Tape 2
record outputs only. If you have only one tape deck it is suggested that you connect
this to Tape 2 so that you can control which source you wish to record separately from
the source you wish to listen to.
THE PHONO AUX INPUT
The first input of the F2 is an Auxiliary Line inpu t. Optionally this can be fitted
with an MM Phono adaptor ， please contact your dealer for further details.
TAPE DUBBING
To record from Tape 1 to Tape 2 select Tape 1 on the Output to Tape 2 selecto r.
If you wish to hear the recording being made also select Tape 1on the Source selec-
to r.
To record from Tape 2 to Tape 1 select Tape 2 on the Source selector.
