FUNCTIONALITIES
GENERAL INTRODUCTION
The processor static APG SPWX is designed to optimize the operation of DX12 & DX15 speakers and
subwoofers SB115, SUB138P & SUB238S in the applications of a floor or side fill or drum fill with sub.
It integrates all the functions of electronic filtering to optimize the frequency response of speakers
and subsonic protection.
This processor offers 4 channels, each one includes: a resonant high pass filter, a low pass filter, a
shelving filter and three cells of parametric equalization. The "sub" output includes a resonant high
pass filter, a low pass Linkwitz Riley 4th order (24 dB / octave).
The connection is made with a slope of 24 dB / octave with a cutoff frequency of 110Hz between
speakers and subwoofer.
This processor operates in two modes:
4 independent channels
2 full range monitoring channels and on 2-way active mono channel (mid/hi + sub)

WIRING
The processor is the last item in the chain before the amplifier.
The processor receives input signals from the console or effect rack. Its outputs are directly
connected to amplifiers.
1°) Mode with 4 channels:
2°) Mode with SUB:
NOTE : in this mode, input 3 does not operate, only the physical output is used for the sub processing

CONTROLS DESCRIPTION
FRONT PANEL
1) Hard-Bypass (1 +2) / (3 +4): This feature pairs to disable the processor, to isolate the amp and
can be used without other forums have changed the internal wiring.
2) DX15/DX12: This function is used to select the speakers DX15 or DX12.
3) Stand / Floor:
Pressing this key switches the mode "stand" when speakers are set up on a stand. Then, the
frequency response is useful for high precision vocal reproduction and medium throw
application (distributed sound system).
By disabling this key switches the mode "floor” when speakers are coupled with the floor. In
this case the effect of the coupling with the floor allows all kind of full range musical
application stage and near field monitoring.
4) HF EQ: This knob controls the clarity of the system to change the spectral balance of the system
depending on the acoustic environment, listening distance and coupling effects.
5) Signal LED: This LED is used to display the presence of a signal higher than - 20 dB on each output.
6) With / off Sub (3&4 only): Pressing this key activates a subwoofer channel on the output of
channel 3 and inserts a high-pass filter in the response of channel 4 for the crossover between speaker
and subwoofer.
7) Sub Level: This knob controls the sub level when the function 6° is activated. A centre position, the
trigger materializes the nominal level of the subwoofer. The range is from infinite attenuation to 6 dB
gain. It is advisable to adjust the subwoofer channel level after installation of speakers.
8) Power: This LED indicates the presence of voltage. The processor can be left running continuously;
there is no power switch.

REAR PANEL
9) Power supply connector : The base area is the IEC standard, the centre pin is grounded. For
security reasons, it must always be connected.
10 °) The rear panel has 4 channels. Each channel has an input and an audio output.
11 °) Audio input connector XLR female 3-pin: These connectors are wired as completely
symmetrical: pin 1: ground, pin 2: hot, Pin 3: COLD. Pin 1 of the two inputs is connected directly to
the chassis and feed the signal processing chains. You can use them with an unbalanced source by
connecting pin 3 to ground lug to the source.
12 °) Audio outputs Connector XLR male 3-pin: These connectors deliver the balanced outputs
processed signals and they are wired as follows: pin 1: ground, pin 2: hot, Pin 3: COLD. You can use
them with an unbalanced source by connecting pin 3 to ground lug to the source.
Note: pin 1 of the output is decoupled from the mass for audio frequencies but is grounded to
ensure the rejection of radio frequencies, ensuring electromagnetic compatibility of the processor.
Result: The amplifier connected to the processor provides grounding the cable shield connected to
their inputs.
Note: The processor uses a circuit ground loop eliminator. If a parasite snoring occurs in a facility, it is
not due to a ground loop.
During use of the subwoofer (activation of function 6) With Sub), the output of channel 3
is used for the Sub signal (the input 3 is deactivated). For speakers DX12 or DX15, only
input and output of channel 4 are activated.
The main fuse must be replaced only with the same type and value.
