Delta no digital pre-amplifier
Installing and using your
Delta 110 pre-amplifier
Mains Supply
_ The Arcam Delta 110 may be supplied to work on any of the
following AC voltages: 110V/220V and 120V/240V (1OOV units can be
supplied to special order). Check that your local mains supply voltage
agrees with the voltage setting indicated on the back panel of the Delta
110. If not, please contact the factory or your national distributor for
details of how to proceed further
A detachable mains lead is supplied with the Delta 110. The
cores of this lead are coloured in accordance with the following code:
Green and yellow - Earth
Blue ^Neutral
Brown - Live
Note: Export units for certain markets have moulded mains
plugs fitted as standard.
As the colours in the mains lead may not correspond with
the coloured markings identifying the terminals in your plug, proceed
as follows:
The wire which is coloured green and yellow must be
connected to the terminal on the plug which is marked by the letter E or
to the safety earth symbol, or to the terminal coloured green or green
and yellow. The wire which is coloured blue must be connected to the
terminal which is marked by the letter N or coloured black or blue. The
wire which is coloured brown must be connected to the terminal which
marked by the letter L or coloured red or brown.
Fuses
If the mains plug is fused, fit a 3 amp fuse.
The AC supply inlet to the Delta 110 uses a standard lEC
chassis mounting plug.
The lEC line socket on your mains lead and the lEC plug on
the Delta II0 are a tight fit; before first using the Delta 110 it is therefore
important to ensure that the socket is firmly pushed home into the
chassis plug.
Under no circumstances should the Delta 110 cover be
removed unless the supply is disconnected at the wall socket.
Notice
1. Please retain the carton and all packaging materials
provided with this equipment so that it may be repacked correctly
if it ever becomes necessary to transport the unit or to return it
for service.
2. If servicing is required then the equipment should be
properly packed and returned to the dealer from whom it was
purchased. It is essential to include a covering letter giving your
name and address and a brief but thorough description of the fault.
Connections and warming up
There are two points that should be noted before using your
Delta no.
Firstly, it is advisable that your system is switched off before
connecting it up to the Delta 110. This will avoid possible damage to
your loudspeakers. At the very least ensure that the volume control on
the amplifier is turned down, or an unused input is selected.
Secondly, although the Delta 110 will play music within
seconds of switching on, in common with other audiophile products its
internal circuits take some time to stabilise fully. We have found that the
very best sound quality may not be obtained until the unit has had some
time, possibly up to twelve hours or more, to warm up.
