11. AC 230V:
The power cord is plugged in to the panel connector containing an integrated fuse (8A/M).
The device becomes active, when a voltage of 230V AC is applied
12. DC IN 24V:
The 24V DC power supply is connected to the terminal block. In case of a breakdown of the
230 V supply a switch to the 24V DC supply is carried out without interruption. As long as
a supply via 230V AC is made the power consumption at the 24V DC input is kept at a
minimum level (40mA for measurements).
13. CH 1 Volume:
Volume control for channel 1; adjustable with a little screwdriver.
14. 1 IN1:
Balanced signal input for channel 1.
15. 1 IN2:
Second, symmetrical signal input for channel 1. If the corresponding terminal is „Switch IN2“
to set to GND, this signal is alternatively used instead of “1 IN1”.
16. SWITCH IN2:
Used for switching from 1 IN1 to 1 IN2. Becomes active when contact is set to GND.

17. PILOTTONE:
A pilot tone signal connected to this terminal (unbalanced) is added to the input signal 1.
The volume control has no effect on the pilot tone.
18. CH 1 OK:
Floating contact, closed in case channel A works in proper conditions. After switching on the
contact remains open for a few seconds until the protection mode is terminated and the
speaker
output
is
enabled.
19. 24V OK:
Floating contact, closed when 24 V DC is applied properly
