Digital input and output – optical & coaxial
The ADDA 192-S offers digital connectivity via the digital
interface port provided on the rear panel. Connections for
coaxial and optical S/PDIF formats are provided.
Digital Output
Converted analog input signals are converted to a digital (A/D)
stream and routed to both the coaxial and optical S/PDIF output
connectors. Connect either of these connectors to the digital
input of your destination device (DAT, workstation, sound card,
etc).
Digital Input
The coaxial or optical S/PDIF format digital input connectors are designed to accept a digital
signal from your digital recorder, workstation, or other compatible digital device. The built in
digital to analog (D/A) converter then routes the converted signal to the analog and headphone
amplifier outputs.
* Note: This signal can be blended in with the analog input signal via the Digital and Analog
rotary mix controls.
4. FRONT PANEL CONTROLS & INDICATORS
4.1 Independent (2x) rotary gain controls and peak LED indicators
Rotary gain controls
Each of the ADDA 192-S’s input channels feature a rotary gain control for variable adjustment of
the desired pre-amplifier level. Clockwise rotation increases the gain, whereas anti-clockwise
rotation decreases the gain.
* Note: Always begin using the ADDA 192-S with all gain controls set to the minimum value. This
way you can increase each channel gain gradually to the desired level without experiencing
possible unwanted and unexpected loud signal surprises to both you and the rest of your audio
equipment!
Peak LED indicators
A peak LED indicator is provided for each of the ADDA 192-s’s input channels. The peak LED
momentarily illuminates to indicate when incoming signal strength has reached an optimum
input level.
