Arcam Delta 70.2 - Manual (Page 5)

Digital Outputs
The Delta 170 is a transport only CD machine which must be
used in conjunaion with an outboard D/A converter or with DAC
equipped amplifiers or pre-amplifiers.
Since the Delta 170 contains no D/A conversion stages of its
own both outputs are digital.
One is a standard phono co-axial digital output, suitable for
connection to the phono digital input of a D/A converter or DAC
equipped amplifier/pre-amplifier.
A 0.75m, 75 ohm phono co-axial lead is supplied as standard
with the Delta 170 for this purpose.
The second digital output is an optical output which allows
the Delta 170 to be used with equipment possessing the TOSLINK
optical connector. A fibre optic cable terminated with TOSLINK
connectors should be used for optically connecting the Delta 170 to a
D/A converter or DAC equipped amplifier/pre-amplifier. (A suitable cable
is supplied with the Delta Black Box 2, or can be supplied on application
to your dealer, distributor or the factory).
The Delta 170 has been designed primarily for use with the
Arcam Delta Black Box D/A converter. Optimum results can be achieved
by coupling the Delta 170 with the optically compatible Black Box 2.
Positioning your Delta CD player
Your CD machine should be placed horizontally on a flat,
firm surface, not on a soft mat or similar which may limit ventilation.
A Delta CD machine can be stacked but should preferably be placed
either at the bottom or the top of the stack. (If you are using
sorbothane feet under your CD machine and wish to place the player
at the bottom of the stack bear in mind the weight capacity of the
feet). Do not stand the player or sorbothane feet on any equipment
(e.g. a power amplifier) which emits substantial amounts of heat.
Dedicated tables or other specialist supports are
encouraged as they can improve the performance of your player by
isolating it from external vibration. AudioQuest sorbothane CD feet
are a particularly cost effective way of improving the performance of
your player.
If siting the player in a cupboard or wall unit allow a
minimum of 1" (25mmJ above the machine to aid cooling.
