is necessary to configure the Speaker Impedance Switch as well as wire up the speakers according to the specific
speakers you are using. Wiring examples for each of the available configurations are as follows:
Low Impedance (4-8ohm) Stereo Speakers:
Low Impedance (8ohm) Mono Speaker:
High Impedance 70V Speakers:
High Impedance 100V Speakers:

Amplifier Output
The NPA70DA amplifier is capable of outputting the same
power at both 4 ohms and 8 ohms. The amplifier output
power varies depending on the input power supply or PoE
adapter connected to it, it does this by adjusting the internal
gain to allow you to get the most of the amplifier. Please
ensure that you select the correct impedence option via
the speaker impedence selection switch on the rear of the
device.
