9.

 

Connect only to AC power outlets rated 230-240V (or 100-120V), 50-60Hz.

10.

 

Do not use this amplifier if the mains cable is damaged or frayed, particularly check where the
mains cable exits the amplifier and the mains plug.  Protect the mains cable from being walked
upon or rolled over by heavy objects.

11.

 

Only use accessories specified by the manufacturer.

12.

 

The amplifier is intended to use in a 19” rack. Follow the mounting instructions. When racks with
wheels are used, use caution to avoid injury from tipping when in motion.

13.

 

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

14.

 

Do not connect an amplifier output in parallel or series with any other amplifier’s output. Do not
connect the amplifier output to any other voltage source, such as a battery, mains outlet, or
power supply, regardless of whether the amplifier is turned on or off.

15.

 

Do not run the output of any amplifier back into another amplifier's input.

16.

 

Refer all servicing to qualified personnel only. Servicing is required when the apparatus has been
damaged in any way such as:

 

Mains cable, or plug is damaged

 

Liquid has entered the amplifier

 

An object has fallen into the amplifier

 

The amplifier has been exposed to rain or moisture

 

The amplifier does not operate normally

 

The amplifier has been dropped or the enclosure is damaged

17.

 

Do not remove top or bottom covers. Removal of the cover will expose hazardous voltages.
There are no user serviceable parts inside and removal may void the warranty.

18.

 

An experienced person should always supervise inexperienced adults or minors when using
professional audio equipment.

User responsibility

3.5.1

 

Loudspeaker damage

 

Your amplifier is very powerful and can be potentially dangerous to both loudspeakers and humans

alike. Many loudspeakers can be easily damaged or destroyed by overpowering, especially with
the high power available from a bridged amplifier. Always check the loudspeaker’s continuous

and peak power capabilities.

 

Even when using the amplifier’s front panel attenuator to reduce the gain, it is still possible to reach full
output power, if the input signal level is high enough.

 

3.5.2

 

Loudspeaker output hazard

 

Power amplifiers are capable of producing hazardous output voltages. To avoid the risk of electric

shock, do not touch any exposed loudspeaker wiring, when the amplifier is operating. See page

12 Connecting loudspeakers.
