ground of electrical safety, contact the manufacturer instead to try to solve the problem.
- The electrical safety is due to its connection to safety ground. Before connecting and use the device,
make sure that the grounding system is efficient. NORMA is not responsible for any damage resulting from
wrong system grounding or inefficient directives and regulations or a disconnection in any way made,
ground security equipment.
- Check that the power cable network has the ground connection and do not remove it for any reason.T
- The new LED TV or PLASMA TV emit large amounts of infrared rays that can interfere with the IR remote
control signal.
2 - USE
2.1 NORMA IR REMOTE DESCRIPTION
The IR remote can access all operating functions, also contains controls for volume setting, built at two
speeds: Standard (fast, VOL - / VOL + +) and fine (slower VOL-/ VOL +) . On the remote control is also
present the MUTE key that completely mute the output signal. This condition is indicated by the flashing of
the POWER indicator to high intensity.
Some of the controls on the remote IR may be inactive for future use.
2.2 TURN ON \ OFF
The amplifiers of the REVO series are equipped with a sophisticated power on system, integrated with the
system remote control and electronic protections. This system consists of three phases: POWER OFF, STAND-
BY, POWER ON [OPERATE].
2.2.1 POWER OFF: In this phase, the rear control switch is in the OFF position and the amplifier is off.
2.2.2 STAND-BY: placing the rear control switch in the ON position, the amplifier is active in STAND-BY POWER
indicator on the front panel will lights up at low intensity. This condition can be maintained indefinitely, the
amplification stages are not powered, but the amplifier is ready to receive the command switch.
2.2.3 POWER ON [OPERATE]: the power is on to all intents and purposes, this can be determined by the
prolonged action on the front SEL button or IR remote POWER button. In both cases, initially the indicator
flashes for a period of time equal to approximately 10 seconds. Subsequently, the light indicator turns solid,
indicating the complete operation of the amplifier and the connection of the speakers.
2.2.4 STAND-BY: to bring the amp in STAND-BY, long press the SEL button [or the POWER button on the
remote control], the indicator will switch to low-intensity lighting.
2.2.5 POWER OFF: to bring the amplifier in POWER OFF condition, after having acted on the POWER
command, put the rear control switch in OFF position. Never work directly on the rear control without first
place the amplifier in STANDBY.
2.3 PROTECTION CIRCUIT
Inside the amplifier REVO IPA-70B are present some sophisticated protection circuits that control the
temperature of the heatsinks, the presence of any offset current exceeding the limit value and the
abnormal supply of output current (short circuit).
2.3.1 THERMAL PROTECTION
In case of intervention of thermal protection amplifier will automatically shuts down and the Power indicator
goes completely off. You can not in any way turn it back on until the temperature has returned at the
correct value, and this will be indicated by the restart of the POWER of low intensity. Only then you can
repeat the POWER ON procedure. The amplifier will not automatically restores the state of re-ignition.
2.3.2 DC OFFSET PROTECTION
In case of protections for the presence of DC component output, the amplifier turns off and the power
indicator switches to low intensity flashing. You can turn it back on only after switching off the appliance at
the rear switch and leaving it off for at least 10 seconds.
If the fault persists, the amplifier would run again in terms of protection. In this case, try to disconnect all
signal cables and repeat the process of restarting the unit. Should the situation persist, contact your service
representative.
The amplifier will not automatically restores the state of re-ignition.
