IMPORTANT NOTES

This manual is to be considered an integral part of the product, and must always accompany the amplifier 
when it changes ownership as a reference for correct installation and operation as well as for the safety 
regulations.

dB Technologies will not assume any responsibility for incorrect installation of the amplifier.

OPERATING PRECAUTIONS

-

Never force the control elements (switches, controls, etc.).

CAUTION

-

Make sure that the amplifier is positioned in a stable and secure way in order to avoid any 

dangerous conditions for persons or objects.

CONNECTION

-

For connecting the amplifier, use only qualified and experienced personnel having sufficient 

technical knowledge or specific instructions for making the connections correctly and thus 
preventing electrical dangers.

-

To prevent the risk of electrical shock, the amplifier must only be supplied from the mains after all 

connections have been completed.

-

Before powering up the amplifier, it is advisable to re-check all the connections, making sure in 

particular that there are no short circuits.

-

The entire sound system must be designed and installed in compliance with the current standards 

and regulations regarding electrical systems.

CAUTION

-

To prevent inductive phenomena from giving rise to hum or disturbance which would jeopardize 

efficient amplifier operation, the cables that transmit microphone signals or line level signals 
(e.g. 0 dB/V) must be screened and should not be run in the vicinity of:
1)

Equipment that produces strong magnetic fields (e.g. large power supply transformers)

2)

Electrical energy conductors

3)

Lines that supply speakers.

Unplug this apparatus during lightning storms or   when unused for long periods of time.

Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through 
openings.

Refer all servicing to qualified service personnel. Servicing is required when:
-

the power supply cord or the plug has been damaged; 

-

Objects have fallen, or liquid had been spilled into the appliance;

The appliance has been exposed to rain or moisture;

The appliance does not appear to operate normally or exhibits a marked change in 
performance;
