Any deterioration of the amplifier caused by an evident presence of dust and/or
internal humidity, will EXCLUDE of any right of application of the Warranty for this
product.
5.6 Protections
Temperature
An inadequate installation or any other anomaly related to cooling may cause that
the amplifier’s temperature exceeds their safe limit (>90ºC), exposing its internal
components to failure. The temperature protection would activate the corresponding
limiters to reduce (balance) the output power with the over-temperature, in order to
keep the amplifier working safely without undesirable stops. In case the temperature
keeps rising, the corresponding protection circuit will cause a stop during a certain
time according to the seriousness of the anomaly detected. The PROTECT led will
light on and the output of the affected channel(s) will be disconnected.
Before the amplifier completely stops because of temperature problems, it will
reduce the output level by 6dB approximately. Once the temperature reduces to
normal parameters, the normal output level will be re-established.
Short circuit
In case of very low impedance or short circuit in any loudspeaker output, the
PROTECTION led is activated and the output will be disconnected.
Direct Current
In the case that due to some malfunction the power module tries to de- liver direct
current (DC) at the output, the protection circuit will immediately disconnect the
module to avoid damage to the loudspeakers. In that case, the PROTECT led will
light on and the output will be disconnected.
Other causes that could prevent the normal work of the amplifier can also activate
the PROTECT. Under those circumstances, the installation has to be revised
according to the basic principles described below:

Disconnect all the connected peripheral equipment (sources, pre-amplifiers,
and loudspeakers). Leave the amplifier “alone” and verify if the anomaly
disappears or if it remains in only one channel or both.

Temperature: Cooling (possible air obstruction. Check if the fan is working
and make an internal cleaning).

Short circuit: Check the state of the loudspeaker line (possible short circuit,
disconnect and check if the anomaly disappears).

C.C. at the output (DC): Possible serious breakdown. Contact an authorized
technical service.

In all cases it is recommended to go through all previous checkpoints before
contacting the authorized technical service and reporting the observed
problem
