3.2 Cooling
Under normal operation of the power amp, overheating should never be a problem. The air is taken in from the front and
out through the back. It is of course essential that, while the power amp is running, the air is able to circulate freely. The
eciency of the cooling will depend on both the immediate environment (e.g. an enclosed rack, direct sunlight) and if the
front lter is clogged. If the amp is installed in a case, the open area at the back of the case must be at least 140 cm². This
area should be in line with the amp. If this cannot be achieved, a forced ventilation system has to be used.
3.3. Mains
3.3.1 Mains supply
Only connect the LINUS12C amplier to an appropriate AC circuit and outlet in accordance with the requirements indicated on
the rating plate. Only use mains cables with original Neutrik powerCON® 32 A connectors for safety reasons.
The LINUS12C is shipped with an EU Style Schuko connector, which must be protected by a 16 A mains circuit breaker.
US amplier 120VAC ships with 2 meter NEMA L5-30P to powerCON® 32 A. It must be protected with a 30 A mains circuit
breaker. For optimum amplier output, larger circuit breakers may be used with alternative connectors, please contact
CODA Technical Support for guidance.
Please do NOT use much larger mains breakers that recommended here and especially do NOT connect several
LINUS12C ampliers to one single (very large) breaker.
Always respect this rule of thumb for good installation practice for guaranteeing long term reliable, robust and safe
operation: one LINUS12C – one circuit breaker.
As soon as the amplier is connected to mains, the primary capacitors are charged through the inrush current limiter.
At the same time the auxiliary power supply is activated, powering the main controller and the display. This allows
powering up the main SMPS from the switch on the ampliers front panel.
NOTE: Turning the amplier o from the user interface (1/0 switch) does not disconnect the amplier from mains.
Disconnecting the amplier from the mains can only be achieved by physically removing/disconnecting the mains
cable. The mains cable therefore has to be freely accessible at all times.
Attention: Never unplug the powerCON® connector while the amplier is playing music. Always turn the amplier o
from the front panel before disconnecting the powerCON® connector.
Alternatively, you can disconnect the amplier from the mains via an external all-pole disconnection (e.g. mains breaker).
Disconnect the mains cable during a lightning storm or when the amplier remains unused or unsupervised for a
prolonged period of time. If a power cut occurs while the amplier is switched on, it will restart automatically once the
mains distribution has been restored. All settings prior to the loss of power will be maintained.
For more information regarding the mains protection refer to chapters 4.2 - 4.3 (p. 28).
