On the rear panel of the P30K you will find three sets of
outputs to the loudspeakers, marked 4 Ohm, 8 Ohm and 16 Ohm.
These outputs will accept loudspeaker cables terminated in any of the
following ways: spade terminals, bare wire or 4mm plugs.
Connect your loudspeaker cables to the output which is closest to the
nominal impedance value of your loudspeakers. If in doubt, consult
your loudspeaker User Manual or refer to your Authorised Dealer for
advice.
Remember when connecting the loudspeaker cables to
respect the correct phase (red = +/black = -) for each channel.
P30K in Mono Use
The P30K is supplied from the factory for use as a stereo
amplifier. It may however be used as a mono amplifier by making the
following adjustments:
-
with the amplifier switched off, move the stereo/mono
switch on the rear panel to the mono position. Unscrew
and remove the red (+) loudspeaker output terminals.
-
referring to the printed instructions on the rear panel,
insert the three gold links as indicated.
-
Replace and retighten the terminals. Note that this
operation modifies the output impedance and provides
double the power output from the P30K.
-
N.B. In mono use you may insert the input from your
preamplifier into either Left o Right input.
The P30K has been designed and built to withstand both
short-circuit and no-load conditions, even for prolonged periods of
time. However, we do not recommend you try this out ! Remember
that it is good practice to ensure that all input and output connections
are securely made and correct when the equipment is in use.

REMOVAL OF THE PROTECTIVE
VALVE COVER
The
P30K
is supplied with a protective cage for the valves. This can
be removed to allow valve fitting and replacement. A hexagonal key
is supplied for this purpose. To remove the cage proceed as follows:
-
Insert the hexagonal key into the square holes at each
corner on the top of the valve cage.
