Page 9: Overview
Signature DAC 1 is a single stereo digital to analogue audio converter. Signature ADC 1 is a single stereo analogue to digital converter. Signature ADDA 1 is a bi-directional analogue/ digital converter containing 1 x DAC 1 and 1 x ADC 1. -
Page 10: Physical Installation
PHYSICAL INSTALLATION The Glensound Signature Series have been designed to be highly versatile for installation and can be installed in 19” racks with either their front or rear panels facing the front of the rack. They can also be mounted underneath desks or work tops and can be either permananetly mounted or stood (using the supplied feet) on top of desks or worktops. - Page 11 SWAPPING RACK EARS TO ALLOW THE REAR TO BE INSTALLED AT THE FRONT OF A RACK PART No Signature Series PWR ON Keeps Working PIN 1 = GND PIN 2 = +12V (100mA) PIN 3 = -12V (100mA) 100-240V +/-12V - - - 50/60Hz 2.7 Watts First remove the 4 silver button head screws that fix the rack ears onto the front of the unit as shown in the top picture above.
