INTRODUCTION
Congratulations on the purchase of your new A1008 CD
player.
The A1008 CD has extremely low jitter, vanishingly
low distortion, exemplary linearity and ultra low noise.
Its case design complements the A1008 series
components which include an integrated amplifier all in
the same convenient size.
Great attention has been paid to internal layout,
isolating each circuit section to prevent possible
interaction.
For added convenience the front panel display and
controls are duplicated on the top next to the mechanism.
This allows easier track selection and control.
The CD digital data streams are first up-sampled to
192kHz, which moves noise, jitter and distortion
artefacts well above the audio band. They are then
passed through a new, low noise, low distortion 24-bit
dual-differential digital-to-analogue converter, which
allows simpler filtering of the analogue output. This in
turn gives an improved audio response without the need
for sharp filters that degrade sound quality. The result is
a CD player which has a smoother response than
previously possible with none of the “hardness” of other
units.
Another feature of the A1008 CD is an additional high
quality ECC88 valve buffer stage output for added valve
warmth to the sound. Selecting between valve sound or
standard solid state output is allowed, by connecting to
the relevant RCA audio output sockets.
The resultant performance achieved by this unit is
among the best in the world. It has excellent signal to
noise ratio, low distortion, wide bandwidth, huge
dynamic range, extraordinary resolution and fine detail.
NOTES ON USING COMPACT DISCS
Always hold discs by the edges and make sure they
remain clean - do not touch the surface. Keep discs away
from direct sunlight and heat sources, such as radiators.
Clean discs with a cloth before playing them, but do not
use solvents such as benzene, thinners, or antistatic spray
intended for analogue records.
After playing, always return the disc to its case for
storage.
INSTALLATION
Position the A1008 CD on a stable, horizontal surface
where there is no risk of it being knocked, or subjected
to vibration such as from loudspeakers.
Protect your A1008 CD from humidity - if the unit is
moved from a cold place to a warm room, or in generally
humid conditions, moisture can form on the pickup lens
inside the player, preventing the laser beam from reading
the disc. If this happens, remove the CD, close the arm,
and leave the unit switched on for an hour or so to allow
sufficient time for the moisture to evaporate.
AUDIO CONNECTIONS
Outputs
: Connect your amplifier inputs to the RCA
sockets on the back panel marked as
LEFT
and
RIGHT
outputs.
There is a choice of outputs available:
Use the Valve Outputs for best in sonic performance
Use the Solid State Outputs if preferred
If desired, the unit can also be attached to an external
DAC of your choice. The unit outputs COAX and
OPTICAL digital signal stream at 44.1kHz.
POWER CONNECTIONS
The unit plugs into mains supply using IEC mains lead.
For increased dynamic range and audio quality, the unit
may also be powered from a
Musical Fidelity
A1008
Integrated Amplifier power supply. This also makes it
more convenient as the CD and amplifier are now
controlled by the A1008
Integrated
OPERATE switch.
Connect the 3-way DIN lead (supplied with CD player)
from the CD OUTPUT on the A1008 power supply to
the CD power input on the 1008 CD. The connector
should fit comfortably when properly seated.
Do not force the connector.
SWITCHING ON
For mains connection
, use the supplied IEC mains cable
to connect the unit to the mains supply. Press the rocker
switch on the back so it’s in the ON position. The red
mains power LED should light on the front panel. To
operate unit press OPERATE button on front panel. The
red led will go out, and the OPERATE LED and
displays will light indicating the unit is ready to use.
For A1008 power supply connection
, use the supplied
3-way DIN cable to connect the units’ POWER IN
socket to the power supply CD power out. The rocker
switch on the back is no longer operative as the unit is
now controlled by the power supply on/off switch. The
red mains power LED will not light on the front panel
with this connection. To operate unit press OPERATE
button on front panel. The OPERATE LED and displays
will light indicating the unit is ready to use. The unit can
now be switched on or off via the A1008 integrated
OPERATE button.
Please note the A1008 CD player “remembers” how it
was switched off; it will operate from the A1008
amplifiers’ OPERATE button
only
if last switched off
from there. If the A1008 CD OPERATE button was
used to switch off, the amplifiers’ OPERATE button
should be pressed first, then the CD players’ OPERATE
button to get the CD player back on again.
CLEANING
Before cleaning the unit, switch off power at the mains
switch and remove the mains plug from the wall socket.
Clean the cabinet and remote control unit using a moist
cloth. We do not advise using solvents, white spirit or
thinners as they could damage the surface finish.
