Notes:
• Both the 4 - 16Ω and 100V terminals cannot be used at the same time.
• Impedances indicated in the figures represent the total speaker system (load) impedances.
• Loads presented to the amplifier must be equal to or greater than listed above. Speaker
impedances must be measured using a true impedance meter, do not standard multimeters.
Connection With The Mains
Connect the unit to the mains via the IEC mains
inlet using the 13A UK - IEC cord supplied.
The earth has to be connected.
Switch the unit on. After switching on the speaker system, wait 8 - 10 seconds before you turn the volume control
up in order to avoid speaker damage.
CAUTION!
Increase the level of each channel up to the point where the clip LEDs illuminate.
Always check the sound pressure level with a meter in order to keep to the legal threshold.

WARNING!
Be sure to attach the supplied terminal cover attached after connection.
Because high voltage is applied to the speaker terminals, care should be
taken never touch these terminals to avoid electric shock.
All speaker connections should be made using bare wire or suitable insulated
crimp terminals. Please ensure no loose strands are present as these may
short across terminals causing damage to the amplifier.
