Delta 60 integrated amplifier handbook
Tuner input
The tuner input is suitable for use with almost any AM or FM
tuner. Connect your tuner to the amplifier using the phono sockets
marked tuner.
Tape input/output
The Delta 60 has connections for two tape recorders and
is suitable for use with almost any cassette, reel to reel or video
tape recorder:
1 connect the 'record' leads of your tape recorder to the
phono sockets marked 'out' on the rear of the Delta 60 using phono/
phono leads
2 connect the 'playback' leads of your tape recorder to the
phono sockets marked 'in' on the rear of the Delta 60 using phono/
phono leads
Loudspeakers
The loudspeaker outputs are suitable for driving loudspeakers
in the range 4-16ohms impedance. The loudspeaker output sockets will
accept 4mm (banana) plugs. A set of 4 suitable plugs is supplied as
standard with the Delta 60. The Delta 60 has two sets of speaker outputs,
marked main and switched (SP2). The main outputs, which offer a slightly
superior sound quality to the switched, are suitable for use where
loudspeakers are to be used alone or where loudspeakers and headphones
are to be used at the same time.
The switched (SP2) outputs, in addition to the above, offer the
possibility of using headphones only. The switched (SP2) outputs are
operated by depressing the SP2 switch on the front panel of the amplifier.
When the SP2 switch is depressed the operation of the switched outputs is
identical to that of the main outputs. When the switch is out the switched
outputs are off, allowing headphones to be used alone.
The switched (SP2) outputs also give the opportunity of using
two sets of 8ohm impedance (or higher) loudspeakers with the Delta 60.
By connecting one set of speakers to the maih outputs and one to the
switched and by depressing the SP2 switch on the front of the amplifier it is
possible to drive both sets at once.
Loudspeaker connections
1 For both main and switched connections connect the
negative side (usually black) of your left hand speaker to the black terminal
of the two sockets marked 'L'. The other (the positive side or red) should be
connected to the red terminal marked 'L'.
2 Repeat for the right hand loudspeaker.
Heatsfnk/ventilation requirements
The heat produced by the amplifier is dissipated into the air
by the finned heatsink on the rear which will, along with the surrounding
panel, become warm while the amplifier is on. The whole back panel may
become quite hot if the amplifier is run near full power. This is perfectiy
normai. However, if it becomes too hot to touch, switch off the amplifier
at once and consult your dealer. It is very important that there is adequate
ventiiation for the whole of the amplifier, but especially for the rear. It is
also important to remember not to place records on top of iti
