OVERVIEW
This handbook covers three products with the ADDA basically being a product that
combines both the DAC and the ADC in one unit.
Signature DAC is a single stereo digital to analogue audio converter.
Signature ADC is a single stereo analogue to digital converter.
Signature ADDA is a bi-directional analogue/ digital converter containing x DAC and x
ADC .
The Glensound Signature Series converter range are professional audio digital and analogue
converters. They are manufactured using high quality components and low noise audio
circuits to provide many years of trouble free use.
The primary job of the converter range is to interface analogue and digital audio equipment
together.
Although traditionally a broadcast manufacturer, Glensound’s products are equally at home
in professional and high end home studios, industrial installations and live pro sound
environments. The converter range can therefore be used in a number of applications.
The converter range are powered from internal switch mode mains power supplies fed from
filtered IEC mains plugs suitable for use Worldwide. They have an internal fuse for safety. The
units can also alternatively be powered from external +/- 2V DC power sources (such as the
Signature Series PS ). If both mains and external DC power sources are present then, if one
power source were to fail the unit would continue to work seemlessly from the other source.
