11 SPEAKER OUTPUTS CH1 - CH4
Four 4-pole terminal block connectors CH1 to CH4 for the connection of speakers in the previously selected operating mode (100 V, 70 V, 4 Ohm). You can find
the pin assignment corresponding to the speaker system on the label between terminal block connections. The packaging includes suitable terminal blocks.
Within DIP switch block no.12, use DIP switches 1 and 2 to select the desired operating mode.
HI-Z / LOW-Z AND PRESET
12
Use DIP switch 1 and 2 to select the operating mode for each pair of speaker outputs 1/2 and 3/4.
Speaker outputs 1 and 2: Move DIP switch 2 to the ON position for HI-Z operation (100V, 70V) and to the OFF position for LOW-Z operating mode (4 OHM).
Speaker outputs 3 and 4: Move DIP switch 1 to the ON position for HI-Z operation (100V, 70V) and to the OFF position for LOW-Z operating mode (4 OHM).
Use DIP switch 3 and 4 to select the DSP preset for speaker outputs 1/2 and 3/4. The description of the preset and corresponding DIP switch positions can be
found in the table below.

DIP SWITCH 1 STANDBY
To activate the automatic standby function, move DIP switch 1 to the ON position. If the standby switch is activated, the amplifier will automatically switch
to standby mode (energy consumption reduction) after approximately 20 minutes of no audio signal. If there is an audio signal again, standby mode
automatically ends and the amplifier is ready for operation again after about three seconds; the standby LED flashes white during this time. The STANDBY
LED on the front of the device is white during normal operation and red when standby mode is activated. Standby mode can also be manually terminated by
pressing the standby button on the front of the amplifier.
