Signal Processors

The DPX Series was created to provide a simple solution

for systems requiring general EQ and comp/limiting. Two

products are available, the DPX-100 Graphic Equalizer &

Compressor/Limiter and DPX-200 Parametric Equalizer &

Compressor/Limiter. The equalizer section and compressor/

limiter may be used independently or chained together in

series. Audio connections are balanced XLR and ¼” TRS.

Using proven circuitry from our popular MQX and PQX

series equalizers and combining these features with our

CLX series compressor/limiters provides two tools no audio

system should be without. By combining the features and

benefits of two processors into one unit, the result is two

powerful tools providing a simple solution to everyday audio

applications.

The EQ section of the DPX-100 is a 15-band, constant Q,

2/3 octave, ISO center, precision wein bridge filter design.

Other EQ features are: frequency range from 25Hz to

16KHz, selectable 15dB or 6dB range, 25mm faders with

‘center off’ position, EQ in/out switch, signal present and

clip LEDs and switchable 18dB/octave -20Hz high pass filter.

Two separate inputs are available in the DPX-200; a micro-

phone preamp with input pad and a line input. The EQ

section consists of 4 bands of filtering; two full-bandwidth

parametric EQs as well as a low-shelf and high-shelf filter.

Other EQ features are: in/out switching for each filter, cut

and boost of 15dB, signal present and clip LEDs, and mas-

ter EQ level control.

The compressor/limiter section uses peak detection circuitry

and has individual controls for gain, threshold, ratio, attack,

release and output level. More compressor/limiter features

include: in/out switch, 11-stage LED gain reduction meter,

selectable 11-stage LED input/output level meter, and a

detector patch point for frequency-selective limiting or

ducking.
