Chapter 1 – Introduction

Congratulations on your DUA II purchase. The DUA II is the smartest audio interface solution for Pyramix users, SOFTIMAGE®|DS users and audio professionals, designed to support a surround monitoring system.

Features include:

• In a single unit, using industry standard audio connections:

4 CH analog line inputs, 4 CH analog line outputs, 2 CH analog line outputs + headphones connector for monitoring, 4 CH AES/EBU inputs, 4 CH AES/EBU outputs.

• The signals from the inputs are also fed to the optical lightpipes in ADAT compatible format. This allows a direct connection to ADAT compatible multitrack devices and other devices such as digital consoles. These optical lightpipe connectors support up to 8 channels of 24 bit digital audio on one single optical fiber with no risk at all of line hum or any other electromagnetic interference.

• Rugged internal power supply. This unit accepts both 110 and 220 voltages for worldwide use.

• All audio connections are made using high quality balanced XLR type connectors.

• Clear and easy to use front panel controls.

• High quality 24 bit A/D and D/A using the latest generation in converter technology.

• High common mode rejection balanced input circuitry on all analog input for optimum rejection of power line

hum, RF interference, voltage drops and other externally generated noise commonly encountered with long audio cable runs.

• All analog balanced output circuitry incorporates the advanced "Twin Servo Drive" output stage for maximum output signal balance ratio performance, even under adverse asymmetrical loads.

• Fits into standard 1 unit 19” rack.

• Local control from the front panel (in stand-alone mode).

• Remote control from Pyramix Virtual Studio software.

• Selectable stereo monitoring of all 8 inputs and outputs.

• Very comprehensive choice of synchronization sources.

• Very low jitter and calibrated internal clock.

• Fully tested for CE compliance for guaranteed safety and stability.
