Back: Controls (Compact Amplifier without DSP)
PA-S 230
1 IEC Connector (Power cord is included)
2 Speaker outputs
Fix the speaker cables to the screw-type terminals.
The speaker impedance should not fall below 4 ohms.
3 Cinch Inputs
4 EXT. ON/OFF – N/C (short circuit plug).
The EXT. ON/OFF-contact must be closed to activate the
amplifier. It may either be closed by a shorting bridge
(delivery condition) or by an external potential-free switch
or contact.
With this contact one or multiple amplifiers in parallel can
be switched on and o via media control or voice alarm
systems.
5 AUTO ON/STEADY ON – DIP switch
In the upper position the channel pair operates in AUTO-ON/
OFF mode and switch into an idle state (SLEEP) automatically
if the input signal is absent for over 10 min. This reduces
power consumption significantly. In the lower position the
channel pair is active permanently (STEADY ON).
6 GROUND LIFT-Switch
In the GROUND position (down) audio ground is
directly connected to the mains ground. If the signal source
is also grounded this may cause humming noise. In this case
the Input connector can be separated from mains ground (LIFT
position)
