Arcam Delta 90.2 - Manual (Page 4)

Rear panel connections
Figure 1
All audio inputs and tape outputs are via RCA phono
connectors. All the phono sockets on the Delta 90.2 are marked 'L' for
left and 'R' for right channels, with the left channels nearer the top of the
cabinet. Your connection leads will be marked 'L' and 'R' or will have a
white or black plug for left and a red plug for right
Disc input
For the purposes of playing records the Delta 90.2 can accept
both moving magnet and moving coil cartridges. For either type of
cartridge the plugs on your turntable lead should be connected to the
disc input sockets on the rear panel of the unit A switch just to the side
of these sockets allows the selection of either MM or MC input The
switch should be left out for use with moving magnet or high output
moving coil cartridges and depressed for use with normal (low output)
moving coil cartridges.
If your turntable has a separate earth lead then this should
be attached firmly to the earth terminal on the rear of the amplifier.
Note
N ever operate the mm / mc switch on the rear oe the amplifier
WITH THE volume control turned up as the resultant electrical surge may
DAMAGE YOUR LOUDSPEAKERS.
Compact Disc input
This input is suitable for use with any compact disc player
(and with our own Delta Black Box D/A converter coupled with a CD
player). Connect your CD player to the amplifier using the phono sockets
marked CD.
Note
Although, like the tuner and tape inputs, the CD has a 'flat'
frequency response, its sensitivity is lower, to take account of the high
output signals generated by CD players. It is possible to use either a
tuner or another line source in the CD input but the amplifier's volume
control will have to be turned up to obtain a volume similar to that
found when using other inputs.
