5. OPERATION ILLUSTRATION

7. Speaker Connection

Before turning on the device, please carefully confirm that the load is constant-voltage or

constant-impedance speakers and set the amplifier to the corresponding output mode. It is

forbidden to switch the constant voltage and constant impedance state arbitrarily when the

power is on.

Constant voltage mode: Turn the switches corresponding to CH1/CH2: 4-16Ω and CH3/CH4:

4-16Ω to OFF.

Constant impedance mode: Turn the switches corresponding to CH1/CH2: 4-16Ω and CH3/CH4:

4-16Ω to ON.

The operation method is as follows:

① When the 100V and 4-16Ω speaker output

mode selection switch is set to the 100V

position, as shown in the figure below:
