1 ACTOR System Components

The ACTOR AT 112 A Mid/High-range Unit
Used on its own, the ACTOR AT 112 A mid/high-
range unit is a full-fledged sound reinforcement
module. Normally placed directly atop the bass bins,
this cab is often called a top. This top can be
operated in full-range mode where it reproduces the
entire frequency range including the low frequencies
for smaller gigs and rehearsals. When several tops
are placed side by side on larger stages, the
trapezoid-shaped housing assures a proper
projection angle.
The ACTOR AT 115 Sub A Bass Unit
The ACTOR AT 115 Sub A bass unit - also a called
subwoofer - not only provides the foundation for the
ACTOR sound, it is also equipped with casters that
make it easy to transport the tops, which can simply
be strapped onto the bass bins. In addition, the
housing features a mounting collar designed to take
a mounting pole if you wish to position the tops at a
higher level.

2 Set Up

If you're planning to operate the system in its
standard configuration, place one subwoofer verti-
cally and the other subwoofer on top of the first.
This set-up provides a stable base for the top and
assures good directivity (see Ex. 1). If you're placing
the ACTOR system on a fairly high stage, the bass
bins can also be laid down horizontally on the stage -
you may even place one bass cabinet on the ground
in front of the stage (Ex. 2a and 2b). Incidentally,
placing the subwoofer directly on the ground delivers
an extra 3 dB. In smaller venues, you can set up a
system with just one subwoofer and a top. In this
case, you should place the subwoofer horizontally,
i.e. lying rather than standing, and use an (optionally
available) mounting pole to position the top at the
proper height (Ex. 3). Both subwoofers and tops are
equipped with mounting collars, making it easy, if
desired, to operate the top as a stand-alone system
when mounted on a speaker stand (Ex. 4).
When you're using two ACTOR systems for larger
venues (e.g. tents or larger halls that hold audiences
of 800 to 1,000) the trapezoid-shaped housing of
the tops automatically assures a wider angle of
projection when these are set up as depicted in Ex. 5.
3 Control features AT 112 A/
AT 115 Sub A
1 Lowcut. The Satellite/Full-range switch lets you set
the system to the right operating mode when you are
running it either with or without the ACTOR AT 115
Sub A subwoofer. When you're operating a system
with AT115 Sub As, the switch should be set to
"Satellite" to activate a low-cut filter that kicks in at
110 Hertz to filter low frequencies out. When you do
not have AT115A subwoofers connected, you want the
entire signal including the bass frequencies to pass
through to the top, in which case you would set the
switch to "Full-range".
2 Ground. Ground-lift switch that separates the
signal ground from the chassis ground in order to
eliminate hum. Press this button to sever the ground
circuit.
3 Input. Electronically balanced XLR socket designed
to accept the output signal from the mixing console
(Line).
4 Trough. Parallel output used to route the Line
signal out, e.g. to other systems, individual
components, monitor power amps, etc.
5 Gain. This knob serves to match the power amp to
the input signal level; use it to prevent distortion
when the incoming signal level is too high.
6 Circuit Breaker. This automatic circuit breaker
serves the same purpose as the standard fuses that
you may be familiar with.
If it trips, once you have identified the problem you
can reset the circuit breaker by simply pressing it.
Caution: Always switch the system off before you
reset the circuit breaker (take a look at the mains
power switch and make sure it is set to Off )!
