Addendum

The following points were omitted from the Delta 150 handbook:

The "MUTE" function on the CR50 remote control handset will only work when the "VARIABLE AUDIO OUTPUT" is
connected.

When switching the Delta 150 on from the "STANDBY" mode, the last selected channel number will
appear on the front panel display.

If the Delta 150 is switched on with the power switch on the front panel, It will default to channel 1.

When the Delta 150 is connected to your hi fi VCR using a SCART (or separate audio/video leads), it will be necessary
to switch the VCR to the "AUX" mode in order to record stereo transmissions.

Please refer to the VCR's handbook.

Delta 150 NICAM stereo TV tuner handbook

Introduction

The Arcam Delta 150 is a NICAM (Near Instantaneously
Companded Audio Multiplex) stereo TV tuner which offers the
enthusiast near compact disc quality stereo sound from terrestrial TV
broadcasts in the UK.

The Delta 150 is a stand alone unit built to the highest
standards. It is designed to be used in conjunction with a television or
video system, and complements the existing range of Arcam Delta
hi fi separates.

Although there are many 'stereo' TV sets currently available,
the quality of the TV's own speakers will not realise the full potential of
the Delta 150.

Best results will be achieved when the Delta 150 is
connected to an amplifier and a pair of good quality hi fi loudspeakers.
We recommend positioning your television set midway between your

speakers, and turning down the volume on the TV set. If your room
layout does not permit this, and your amplifier is capable of driving two
or more pairs of speakers, you might choose simply to place a second

pair of speakers either side of the TV and use these when watching the
television. Your main pair of speakers can then be left in their existing
location and used exclusively for the hi fi system.

The Delta 150 is also equipped with a high quality composite
video output. This can be used to enhance picture quality, provided your
TV has a suitable composite video input (usually found on a SCART or
Peritel A/V socket).

Because of its design, the Delta 150's 8 presets can be tuned
and operated in much the same way as a conventional TV set, either
from the unit itself, or via the supplied CR50 remote control handset.
This also provides remote control operation of the volume, mute, and

standby functions.

Please study this handbook carefully to ensure that you get
the best possible results from your Delta 150 NICAM tuner. It will
probably be necessary to refer to the handbooks of your video cassette
recorder (VCR) and TV in order to find the configuration that suits
you best.

If in doubt, consult your dealer. He is there to help!

Installing and using your Delta 150 IMICAM tuner

Mains Supply

The Arcam Delta 150 is supplied to work on 220V/240V AC
mains. A detachable mains lead is supplied with the Delta 150. The cores
of this lead are coloured in accordance with the following code;

Green and yellow - Earth

Blue - Neutral
Brown - Live

If the colours in the mains lead do 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 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 is
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 150 uses a standard lEC

chassis mounting plug.

The lEC line socket on your mains lead and the lEC plug on

the Delta 150 are a tight fit; before first using the Delta 150 it is therefore

important to ensure that the socket is firmly pushed home into the
chassis plug.

Under no circumstances should the Delta 150 top cover be

removed unless the supply is first 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.

Positioning the Delta 150

In general we believe you will find the Delta 150 to be most
useful if it is placed alongside your hi fi equipment rather than your
television. The various audio cables required can then be kept short, to
ensure the highest sound quality. If you own a hi fi video cassette
recorder, there is also a strong case for moving this closer to your hi fi
system. The VCR's audio record and replay functions are then more
easily integrated with the Delta 150 and the rest of your sound system.
Connected to your FM radio tuner, most hi fi VCRs can be used to record
long duration radio programmes if you wish.

Please observe the following precautions when siting the

Delta 150:

Do not place the Delta 150 close to a source of heat (e.g.

direct sunlight, a radiator or a powerful amplifier)

Ensure that air can circulate freely around the unit.
Do not place the Delta 150 directly underneath (or on top of)

a turntable, cassette deck or VCR. The mains transformer of the Delta

150 may, in some circumstances, induce a level of background hum into

the sensitive circuits of these units.

Do not expose the Delta 150 to rain or moisture.

Connections and warming up

There are several points that should be noted before using

your Delta 150.

In particular, it is advisable to switch off your system before
connecting it up to the Delta 150. This will avoid possible damage to
your loudspeakers. At the very least, ensure that the volume control on
your amplifier is turned down, or an unused input is selected.

Although the Delta 150 will receive broadcasts within
seconds of switching on, in common with other audiophile products its
internal circuits take some time to fully stabilise. We have found that the
very best sound quality may not be obtained until the unit has had some
time, maybe an hour or two, to warm up.

Note

When the Delta 150 is switched to standby mode, these

critical circuits remain energised. The optimum audio performance may

then be obtained as soon as the unit is switched on again.
