1 INTRODUCTION
The DPA 28X is a complete 2 input - 8 output digital loudspeaker management system
designed for the touring or fixed sound installation markets. The absolute latest in
available technology is utilized with 64-bit floating point processors and high performance
24-bit Analogue Converters. The high-bit DSP prevents noise and distortion induced by
truncation errors of the commonly used 24-bit fixed-point devices. A complete set of
parameters include I/O levels, delay, polarity, 8 bands of parametric EQ per channel,
multiple crossover selections, compressor, Limiter, USB and Ethernet port connection.
Precise frequency control is achieved with its 1 Hz resolution.
The DPA - 28X can be controlled or configured in real time on the front panel using the
previously stored presets or with the intuitive PC software via the USB or Ethernet
interface. The Ethernet port allows controlling the device from a long distance using just
an Internet connection.

The Tecnare PCC Controller advanced series software application provides real-time
control and configuration editing for the DPA-28X using a laptop or other PC-compatible
computer.
In addition, the application provides control over each individual input channel: Gain,
Graphic EQ, Compressor, main delay, and over each individual output channel:
Crossover, 8 bands parametric EQ, phase inverter, mute, and delay.
In addition, the application provides a powerful real time analyzer with pink noise
generator capability.
Changes made in the PC software are immediately executed in the DPA-28X.
To start the application click on the PCC Icon on your desktop

SIGNAL GENERATOR
By selecting active in the dropdown list, a pink noise signal is generated by the 8 output
channels.
The output level is controlled by the fader control.
INPUT LEVEL
Main delay in ms, meters or feet can be adjusted in this section. The input level is
adjusted by the fader control, it provides signal and clipping indicators.
TECNARE DPA 28X OWNER’S MANUAL
INPUT COMPRESSOR
The input compressor has four controls: Attack, Release, Threshold and Ratio. Click on
the dropdown list to adjust each parameter. Click the Bypass button to turn it off.
About Compression: A compressor is used to reduce or limit transient peaks in a signal.
As the input level to the compressor increases, the output level increases linearly until the
threshold point is reached. After that point, the output level no longer increases linearly,
but increases at a reduced rate that is determined by the ratio setting.
• Threshold: This control determines the level at which the compressor begins to act on
the incoming signal. It is calibrated in decibels, with a range from –-40.0 dBu to 17 dBu.
• Attack: This determines how fast the compressor reacts once the threshold has been
exceeded. It is calibrated in milliseconds, with a range from 1 ms to
90 ms.
• Release: This determines how fast the compressor turns off once the signal falls below
the threshold. It is calibrated in milliseconds, with a range from 10 ms to 2500 ms (2.5
seconds).
* Ratio: This determines the change in output level as a function of the change in input
level, once the threshold has been exceeded. It is calibrated in decibels, with a range
from 1.2:1 (off) to 30:1.
