USER INFORMATION
doubling the power of your amplifier.
SWITCH ON
When you switch on the A1001 the
unit will initially be in a muted state for a
few seconds to allow the circuits to stabi-
lise and to prevent any switch-on thumps
etc. The volume control position indicator
LED will then light when the unit becomes
active. Note - if you mute the A1001 with
the remote control before you switch it off
you will then need to un-mute the unit with
the remote after switching on.
CONNECTIONS
All connections should be made
with the power OFF.
The A1001 has 6 line level inputs -
CD, Tuner, Aux 1,2 and 3 and Tape. All
inputs are electrically identical and are
suitable for use with any source compo-
nent with an output voltage in the hundreds
of millivolts (mV). This includes CD play-
ers, tuners, tape machines and the audio
outputs of video recorders, televisions,
DVD and LaserDisc players etc. Enthusi-
asts who wish to use a turntable should
purchase an external phono stage such as
the Musical Fidelity X-LP. We recom-
mend that you use good quality screened
interconnects such as the Musical Fidelity
X-LINX for all connections. Do not use
un-screened interconnect cables as they
have inferior performance and in some cir-
cumstances can actually damage the unit.
TAPE RECORDING
The A1001 has a single tape circuit
with facilities for off-tape monitoring with
3-head cassette decks. Connection of your
tape machine to the A1001 should be as
follows. The tape machine's Tape/Line out-
puts go to the A1001's 'Tape' input sock-
ets.
THE A1001
The A1001 CLASS A SUPER
INTEGRATED AMPLIFIER was
conceived as a very powerful integrated
amplifier of the highest quality, inter-
nally structured as fully separate
preamp and monobloc power amp
stages. The separation of the pre and
power-amp stages allow them to be
fully optimised for their specific func-
tions. In addition this ensures total
freedom from intermodulation and other
distortions and noise that can occur
when these circuits are combined. The
preamp and each power amp stage are
built on separate PCBs with separate
power supplies and a separate magneti-
cally sheilded mains transformer each.
By packaging the unit as an inte-
grated amplifier we were then able to
provide perfect interconnection between
these stages, particularly as regards the
crucial earth return currents, and re-
move any need for potentially sound
degrading interconnects whilst also
giving a more compact amplifier solu-
tion.
All signal circuitry in the A1001 is
fully discrete, no I.C.s are used, all
circuitry has been designed 'from the
ground up' specifically for the A1001.
LOUDSPEAKERS
To get the best from your A1001
for a realistic soundstage and full dy-
namic range, use it with loudspeakers of
a reasonable efficiency. An average
rating for a loudspeaker these days is
about 88dB. This should mean that for
an input of 1 watt, measured at 1 metre
distance, the sound output will be 88dB.
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 91dB is equivalent to
