Basic structure

With the DA source button you select the source for the built in 8/2 mixer and for your
analog outputs. You can choose between the input selected on the AD-D button or any of
the digital interfaces. If a valid digital signal is present the green “Carrier” LED will light up.

If you have installed a ProTools Mix 24 compatible I/O card you have to choose this
interface as Multi 1 or Multi 2.

With the AD-D source button you can choose the input (for 2 channels at a time) which
will be availably as a digital signal on all digital multi-channel
rate, dither and sync selected at the sample-rate, dither and sync buttons.

outputs with the sample-

If you choose an analog signal the converter will work as an A/D converter.

If you choose a digital signal the converter will work as a sample-rate and/or a format

converter. If the incoming digital signal is not in sync with the converter it will be detected
and the signal will be sample-rate converted.

If a valid digital signal is present the green ‘Carrier’ LED will light up.

The Level/data controls are used for all selections and adjustments. For adjustment of a
parameter related to a channel (1-8) use the corresponding Level/data controls. For adjustment
of an ‘over-all’ parameter use the Level/data controls and the LCD display for channels 7 & 8.

All primary functions are available by pressing only one button!

The short cut buttons provide fast access to the primary functions in the AD-DD and Monitor

The short cuts are only active when the short cut button is pressed. After releasing a short cut
button the ADDA 2408 returns to the function prior to short cut activation.

If for instance the Mic gain in dB is selected and a short cut is activated, the corresponding
function may be adjusted using the Level/Data knob for one or more channels. By releasing the
short cut button the ADDA 2408 returns to the Mic gain in dB function. It is therefore easy at all
times to identify the active functions of the ADDA 2408..

It is recommended to set the ADDA 2408 into Mic gain in dB or Monitor level mode while
recording.

AD-DD Source Button

AD-D source button

With the AD-DD source button you can choose between the different analog or digital interfaces
for two channels at a time.

The selected input will be available on all
synchronization chosen at the Sample-rate, Dither and Sync buttons.

This way the unit can be either an A/D, a sample-rate, or a format converter between the digital
I/O’s mounted in the ADDA 2408.

If the selected digital input has a different sample-rate or synchronization than the sample-rate and
synchronization chosen at the Sample-rate and Sync buttons, the unit will auto-detect the
difference and use the built in sample-rate converter automatically.
