INSTALLATION
Racking
All amplifiers are 19-inch rack mount width. PS-200 and
PS-400 are 1U DIN in height. PS-800 and PS-1400 400 are
2U DIN in height.
Four front-panel mounting holes are provided for use with
M5 or M6 or 1/4” screws. To avoid bending the chassis in
rack mounting applications where the rack will be
transported, mount the amplifiers to the back of the rack
using the rear mounting holes. Alternatively, place the
bottom amplifier against the base of
the rack and pile the amplifiers with
no clearance in between.
Amplifiers’ dimensions can be found
on the “Line Drawings” section of this
manual.
Cooling
A fan cools the aluminium heat sinks
and transformer from back to front.
When mounting the unit onto a 19-
inch rack, a rack cooling system is
not required, since the air is
exhausted out through the front grille.
However, the rack must not be sealed, and it should at
least have a large enough ventilation grille to allow air into
the rack.
Input cable connections
The Input Cabling Appendix shows balanced and
unbalanced connection from different types of connector to
the amplifiers.
Speaker cable connections
Either the binding posts or the Speakon connectors (PS-
800,PS-1400) can be used.
The binding posts can be used with bare wire or banana
connectors. In either case, ensure that you remove the
required length of cable sleeve that allows for the conductor
itself to be hidden. Always note polarity (red=+,black=–).
Speakon connectors offer quick connection for portable
applications. To enable a Speakon connection, plug the
male connector into the outlet and rotate it clockwise. It
will then lock into place and be ready for use.
The Appendices of this manual include a table to aid in the
selection of the appropriate cable gauge.
Connection to mains
Nominal AC voltage will always be indicated on the back
panel. 230V and 115V versions are available. Be sure your
unit has the nominal AC voltage for your country.
Power consumption
Can be seen on the accompanying table for 230V. Double
the ratings to get the 115V current consumption.
International safety agencies specify AC consumption using
pink noise at 1/8
th
of maximum power. This is done to
represent the current requirements to reproduce a typical
musical programme. The 1/3
rd
power rating represents a
worst case scenario, while the maximum power represents
consumption with sine wave signal, which will never occur
in practice.
