Overview
2.1. Introduction
The DMA 8X8 is equipped with several core technical features to facilitate the
work of audio engineers. DSP-based remote audio equipment is routed, processed
and controlled by computer. The Tecnare DSP Controller is a Windows-based
application, which is used to conduct configuration and control of DSP
hardware. DSP Controller has 16 built-in presets, and the modules and
sequences for each preset can be flexibly designed in accordance with the
designer’s requirements. After the design is finished, it can be saved for
future use. The sequences and parameters of DSP Controller’s built-in
processing modules accord to most of the application scenarios without any
change. DSP Controller is a full-featured application, including the parameter
adjustment and peripheral acces- sory settings of all modules, such as RS232,
RS485, click-and-drag panel configuration and optional Dante network audio
control. The most interesting part is the user interface, which allows the
engineer to customize user interface so that the Integrator can edit it or the
on-site technicians or end users who have no idea of relevant techniques can
operate it. Superior safety functions make it possible for the end users to
access to the controls allowed by the engineer or designer.

features a couple of removable balanced 12 pin Phoenix terminal strips .
Unit gain (0dB) is set through volume control, and the analogue output section
is corrected to +4dBu with 20dB headroom. That is to say, 0dBFS digital signal
is equivalent to +24dBu output signal. If other signal levels are required,
you may change the volume to achieve it.
3.3. Audio Wiring Reference
- Balanced Connection
The HOT, + or ‘in phase’ connection should be made to pin + on the terminal
strips or pin 2 of the XLR connector.
The COLD, – or ‘out of phase’ connection should be made to pin – on the
terminal strips or pin 3 of the XLR connector.
GND Pin, corresponding with Pin 1 of the XLR connectors is internally
connected to the chassis.
The shield of the input cable should always be connected Pin 1 to ensure the
EMC performance and
Note: For one XLR interface, the female connects to the output device and the male connects to the input device.
- Using unbalanced connection
Please note that the use of unbalanced connections is not recommended, however when connecting the matrix to an unbalanced audio source, the signal conductor should be connected to XLR pin2. The ‘Cold’ conductor or cable screen should be connected to pin 1 with a short connection made between pin 1 and pin3 as shown in Figure 8.
