ACTOR ADX 112 A
4 Connections and Control
Features
4.1 ACTOR ADX 112 A
1 Power Switch
Handling: This is the on/off switch for the active
system. When engaged, the system controller's
display lights up orange.
Always switch the ACTOR DX active system on last,
that is, after powering up all other components, and
switch it off first before powering down all other
connected devices.
2 Mains Input
Connecting cords: Use the factory-included Power-
con cable to connect this socket to a wall receptacle.
Caution! Make sure the local mains voltage matches
the voltage specified on the device. If you connect
the system to the wrong mains voltage, you may
destroy the ACTOR DX system's electronic
components.
3 Link (only 220-240 V version)
Connecting cords: The Powercon Link socket is wired
in parallel to the Mains Input. Connect other load
consumers (for example, another ACTOR DX
mid/high unit or an ACTOR DX Sub A bin) to it.
Heads up: The Powercon Link socket can handle
loads up to 8.6 A and 2060 W (at 230 volts). This
means you can use it to power up to but no more
than two additional ACTOR DX components.
Note: Always switch on ACTOR DX components one
after another to prevent a sudden spike in the
venue's power supply. Otherwise the power surge
may cause the house circuit breaker to trip.
4 Ground
Ground lift button for separating the signal and
9 chassis ground in the event of humming noises.
In the event of low-frequency hum, engage the
9
Ground Lift switch. The ground circuit is severed
when this button is pressed. If this doesn't solve the
problem, check all cords connected to ACTOR DX as
well as all signal cables routed to the mixing console
for damage (see also Tips and Tricks).
5 Input Sensitivity
This selector matches the preamp's input sensitivity
to the mixer's output signal level.
Engage this switch to select either -10 dB (for exam-
ple, for unbalanced 1/4" jacks and consumer level
devices) or +0 dB (for example, for balanced XLR
ports and professional mixers).
Recommendation: Select +0 dB when using a
professional-grade mixer sporting balanced outputs.
This lets you take advantage of console faders' full
control range and helps prevent overloads.
Opt for -10 dB A when using a console with a lower
output level (unbalanced 1/4" output).
6 Input Overload
This LED lights up when the input level is too high
and the entire system (preamp and controller) is
being overdriven. Not only does this result in
unpleasant distortion, it can also harm the system's
components. If the red LED lights up, reduce the
level (volume) at the mixer!
7 Line In
Connecting cords: Connect cords carrying signals
from your mixer (master left/right, line out, or a
similar circuit) to the balanced inputs using a mic
cord equipped with XLR connectors.
Ensure XLR connectors are wired as follows:
1= ground, 2= +, 3= -.
8 Through
Connecting cords: Use this parallel output to route
the incoming line signal to other components (for
example, to additional ACTOR DX mid/high units)
via XLR cords.
9 Limiter LEDs
These are the active system's "rev counters," serving
to indicate the limiter's operating status.
10 Subwoofer Output
Connecting cords: Use this output to send the
subwoofer signal from the DDO™ controller to an
ACTOR ADX 115 Sub A via an XLR cord.
Ensure XLR connectors are wired as follows:
1= ground, 2= +, 3= -.
