Delta 60 integrated amplifier handbook

Introduction

The Arcam Delta 60 integrated amplifier is a product
constructed to a purist design, as evident by its lack of tone controls, which
will meet the requirements of the most demanding listener. Combining
excellent sound quality with sleek, sophisticated styling, the Delta 60 will
form the heart of any high quality sound system. It is, of course, ideally
suited for use with our existing Delta range units, especially the Delta 80
tuner. Delta 70.2 CD player and Black Box D/A converter.

The Delta 60 has five switchable inputs accepting signals from
compact disc, turntable (with facilities for moving magnet and moving coil
cartridges), tuner and two tape recorders. The Delta 60 offers further
versatility by providing outputs for headphones and two sets of
loudspeakers and by allowing mono operation.

Please study these instructions carefully to ensure that you get
the best from your Delta 60. Remember that your dealer is there to help

you. He has full knowledge of all Arcam products and considerable

experience of their use in a variety of systems. If, however, he is unable

to answer your query then please contact us at the factory.

Installing and using your Delta 60 Amplifier

Mains supply

The Arcam Delta 60 may be supplied to work on any of the
following AC voltages: 110/220V 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

60. 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 60. 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 in the plug which is marked by the letter E or to
the safety earth symbol or 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 is marked by the letter
L or coloured red or brown.

Fuses

If the mains plug is fused fit a 5 amp fuse.

The AC supply inlet to the Delta 60 uses a standard lEC

chassis mounting plug.

The lEC line socket on your mains lead and the lEC plug on the
Delta 60 are a tight fit; before first using the Delta 60 it is therefore
important to ensure that the socket is firmly pushed home into the
chassis plug.

Under no circumstances should the Delta 60 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

It is advisable that your system be switched off before
connecting it up to the Delta 60. 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.

cabinet. Your connection leads will be marked 'L' and 'R' or will have a
white or biack plug for left and a red plug for right.

Disc input

For the purposes of playing records the Delta 60 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

Compact Disc input

This input is suitable for use with any compact disc player (and

Connect your CD player to the amplifier using the phono sockets

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.
