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 to OFF.
Constant impedance mode: Turn the switches corresponding to CH1/CH2: 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:
