Delta 110 digital pre-amplifier
2. Connect the 'playback' (or 'line out') sockets of your tape
deck to the phono sockets marked 'in' on the rear of the Delta 110, using
phono-phono leads.
Outputs
The Delta 110 is equipped with two identical line outputs
compatible with power ampiifiers requiring inputs in the range of
500mV to 2V for full power output.
Both pairs of outputs may be used simultaneously if required.
The outputs are short-circuit proof, and are also
automatically muted at switch-on and switch-off.
The output impedance of the Delta 110 is sufficiently low at
25 ohms to allow for runs of audio cable up to about 20 metres to be
used without any serious degradation of sound quality.
Note
A pair of good quality pre to power amplifier interconnect
cables is provided as standard with the Delta 110, but please refer to
'Connecting cables' on page
for further information on this
important topic.
Digital inputs
The Delta 110 incorporates an advanced Push-Pull Bitstream
digital to analogue converter
This will accept the digital output signals from compact disc
piayers or domestic DAT recorders that conform to the S/PDIF standard
(Sony/Philips digital interface). Optical and 75ohm co-axial inputs are
'■ovided. Both inputs will switch automatically between the CD
„ jmpling rate (44.1 kHz) and the DAT sampling rate (48kHz).
Both 75ohm co-axial and Toslink type optical interconnects
of approximately 0.75m length are supplied. These make connecting
your CD player or DAT player to the Delta 110 very straightforward.
If longer cables are required, they should be of the correct
type - for example, regular audio phono-to-phono cables are generally
not suitable. A 75ohm co-axial (aerial or video) cable terminated with
phono plugs should be used.
We particularly recommend AudioQuest video cables (Video
X and Video Z) obtainable from your Arcam dealer or, in case of difficulty,
directly from the factory in the U.K.
Digital monitor output
The digital monitor output is a phono-type co-axial socket
which provides an exact duplicate of the digital input seiected on the
front panel.
For example, if the co-axial input is selected, and it is
connected to your CD player, that digital signal can be fed via 75ohm
co-axial cable into the digital input of a DAT player in order to record
(assuming that the DAT player is compatible with the 44.1 kHz
sampling rate).
The digital monitor output can also be used to 'daisy chain' a
digital signal to a further outboard D/A converter or digital processor.
Note
Because the digital monitor output socket duplicates an
input signal, it cannot change the sampling frequency i.e. a 44.1 kHz
input is sent on as a 44.1 kHz signal.
