LINE IN L/R
3
Analogue audio inputs with balanced terminal block connections. The +, - and G poles are for the
balanced input signal (suitable for unbalanced cabling). The signals of the inputs L and R are
internally mono summed. Terminal blocks are included in the packaging content.
OUTPUT
4
The loudspeaker output with terminal block connection (terminal block included in the packaging
content) enables the use of low-impedance loudspeakers with an impedance of at least 4 ohms
(switch LO-Z/HI-Z in position LO-Z) as well as 70 V or 100 V loudspeakers (switch LO-Z/HI-Z in
position HI-Z). Please observe the correct assignment of the terminal block poles (see TERMINAL
BLOCK CONNECTIONS in this manual). The total power handling of the connected speakers should
be approximately equal to the amplifier power.
HI-Z / LO-Z
5
Before operating the unit, make sure that the switch is in the correct position!
Low impedance loudspeakers: LO-Z
70 V and 100 V loudspeakers: HI-Z
SETTINGS
6
DIP switch 1 STANDBY: Move the switch to the ON position to activate the automatic
standby function of the unit. If the standby function is activated, the amplifier is automatically
set to standby mode if no audio signal is detected for about 20 minutes. This reduces power
consumption in a sensible way. As soon as an audio signal is present, the amplifier is
automatically booted up from standby mode and is fully operational again within approximately
3 seconds. The power symbol on the front panel lights up red in standby mode. If the power
symbol lights up white, the unit is ready for operation.
DIP switch 2 HPF: Move the switch to ON position to activate the high-pass filter (HPF 110 Hz).
STANDBY
7
Standby mode can be activated manually with the help of an external button (momentary
switch). Press the button to activate standby mode and mute the speaker outputs. Press the
button again to end standby mode. The standby function via external button has priority over
the automatic standby function (see SETTINGS).
VCA
8
Terminal block connector for the use of an external volume control. The maximum volume is set
on the VOLUME control on the front panel. Once you have set the maximum volume, you can use
the external volume control to adjust the volume of the unit from the minimum value to the
preset value as desired. Please observe the correct assignment of the terminal block poles
(see TERMINAL BLOCK CONNECTIONS in this manual).
