Arcam Delta 150 NICAM - Manual (Page 8)

Delta 150 NICAM stereo TV tuner handbook
If you have a VCR, TV or A/V amplifier which is fitted with a
SCART socket, you can connect it to the Delta 150 using the appropriate
SCARTlead.
With a suitable hybrid lead, the outputs from the Delta ISO's
SCART socket may also be fed directly to the appropriate BNC or phono
sockets of a VCR, TV or A/V amplifier.
The Delta 150's remote volume facility may be assigned to
the SCART audio outputs by adjusting the small blue SCART audio
switch, located immediately to the left of the main audio output sockets.
For fixed outputs, use the tip of a ball point pen or pencil to push the
switch in; for variable outputs push the switch again so that it springs
back flush with rear panel.
Composite Video Output
The CVBS output is also available on a
BNC socket as well as
the SCART socket described above. The two outputs may be used
together if required, for example to feed the composite video inputs of
both a VCR and a TV/monitor at the same time. Good quality 75 ohm
co-axial cable, or a specialist video cable, must be used for this purpose.
Note that teletext information is preserved on this output, but not
sound. In general the CVBS outputs will provide better video quality
than that obtained by using the remodulated RF output (see below).
Aerial input
This utilises a UK standard 75 ohm co-axial socket. Your
existing TV aerial lead, which is presently connected to your TV set or
VCR, should be connected to this input.
As with any audio or video system, the best results will only
be obtained with a good quality outdoor aerial, correctly oriented
towards the appropriate transmitter(s). To avoid unnecessary
degradation of the signal the aerial downlead must be UHF co-axial
cable of the very highest quality (such as low loss type RG59). We also
recommend against the use of aerial preamplifiers or distribution
amplifiers whenever possible, as these can often introduce more
problems, such as noise and cross-modulation distortion, than they
solve. Your local dealer or aerial contractor should be able to provide
suitable advice on all of these topics.
RF (aerial) output
The Delta 150 is equipped with a male co-axial RF output
socket similar to those used in VCRs. This performs two functions.
Firstly it provides a 'clean feed' of all the UHF TV channels
picked up by the aerial to other equipment further down the chain.
Therefore if the RF output is connected to the aerial inputs of your TV or
VCR, these units can be operated normally, independent of what the
Delta 150 is being used for. A suitable lead is provided with the Delta
150 for this purpose.
Secondly, the socket is connected internally to a remodulator
unit. This re-broadcasts, on or around channel 36, whichever TV station
is selected on the Delta 150 (n.b. The remodulated output includes the
video signal, with teletext and FM mono sound, but not NICAM sound).
If you tune your TV to the remodulated output channel, then
the Delta 150 can be used for normal selection of up to 8 channels of
sound and vision, either directly or via its CR50 remote control handset.
Note
The RF output does not work if the Delta 150 is turned fully
off. If it is left in the 'standby' mode, then the 'clean feed' circuit will be
operative. The remodulated output only functions when the Delta 150 is
switched fully on.
