Never connect either output terminal to ground or to some other output or input terminal (see warnings in chapter 1)
For normal
Keep the loudspeaker cables as short as possible and use good quality stranded cable. Do not use shielded wire, such as microphone or guitar cable. Remember that the speaker cable reduces the power of the amplifier in two ways:
It increases the load impedance and introduces resistive power losses.
WARNING: To prevent electric shock, do not operate the amplifier with any of the loudspeaker cable conductors exposed.
8 OPERATION
8.1Operation precautions
•Make sure that the power switch is set to “OFF ” before connecting any input or output or operating the switches on rear panel. See pages 9 about installation.
•Make sure that the AC mains voltage is correct and is the same as the one printed on the rear panel of the amplifier. See pages 9 and 10, about operating voltage and power consumption.
•Make sure that the switches on the rear panel for the different operating modes and the clip- limiter switches are in the correct position. See page 7 about operating modes and page 14 about clip limiters.
•It is always a good idea to turn down the gain controls during
