INSTALLING THE QUAD 99 STEREO POWER AMPLIFIER
Before connecting the QUAD amplifier to the AC mains supply check that
the voltage marked on the back matches the voltage of your supply.
Mains On/Off Switch
The Mains On/Off switch is on the rear panel. When the amplifier is
connected to a Quad 99 system with the special AMPBUS cable this switch
should normally be left switched on as the amplifier will be remotely
switched.
Where the amplifier is not part of a Quad 99 system the Mains On/Off
switch should be switched off when the amplifier is not in use.
Signal Input Connections
When the 99 amplifier is used as part of a 99 system, you should use the 99
AMPBUS lead provided to connect to the output of the 99 preamplifier or
the 99AV processor.
Quad 99 units are connected via special multiway cables. The ends are
terminated with a male and female 15 way D type connector. They are
available in lengths of 160mm and 1m.
When used to link control units they are referred to as QUADLINK and
when connecting amplifiers they are referred to as AMPBUS cables.
AMPBUS signal is differential. This offers performance advantages over the
usual unbalanced mode.
