INSTALLATION
Racking
All amplifiers are 2U DIN high standard 19-inch
rack mount width.
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.
The fan speed is variable.
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 can be used.
Switch off the amplifier and unplug the unit
from the socket before making any connections.
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

a l l o w s f o r t h e c o n d u c t o r
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 is 230V. Export versions
may operate at 115 V AC. Nominal AC voltage will
always be indicated on the back panel.
For electrical safety, the amplifier uses an
automatic power switch that will switch off in the
event of overloading or overheating of the power
supply.

Current draw
Consumption can be consulted, for 230 Vac,
at the table in Appendix C. Multiply by two times
for 115 Vac.
IEC60065 international standard specify AC
consumption using pink noise at 1/8 of maximum
power. This is done to represent the current
requirements
to reproduce a typical musical
programme. The 1/3 power rating represents a
worst-case scenario, while the maximum draw
represents consumption with sine wave signal,
which will never occur in practice.
