Wiring And Ac Power Supply - Toa DA-1250D Operating Instructions Manual

Wiring and AC power supply

Power & Wiring distribution
The amplifier power supply isn't a non-resistance load and its use on unstable music signal, so it can not
calculate with "Voltage x Ampere=Watt" ,the actual power consumption can not be fixed formula .
Referring to the power dissipation and power supply/AC of different product for wiring
We suggest the users to match not less than the following wiring size specifications, to obtain the better
comprehensive properties.
The Standard Voltage 100-240V

DA-1250D 1100W
When you use 1 power supply socket for many amplifiers, the power cable of the outlet should be bigger
and also the internal cable of socket.
Please check the power voltage remark in the rear panel:
220V/240V = voltage range between AC200V to 240V.
Stable power supply voltage can ensure the amplifier works steadily.
The output power will be adjusted according to the difference voltage of power supply
More than one installation
When in the same AC power supply and its total power is more than 10kW, we suggest you use three
phase and five wires in power distribution and the null wire can not use with Ground wire together.
Check after powered
For the first time powered, you have to use the multimeter to measure voltage, and confirm
whether meet the requirements of the product. And do not connect signal and speaker after
you confirm everything is ok, then power off the amplifier.
The importance of Ground wire
You should connect Ground for safety use.
If you don't have qualified Ground connection or not use the Ground, you may have a electricity shock.
To avoid such thing happen, please connect Ground when you use.
