Page 5: Basic Structure
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. -

Page 7: Short Cuts
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.. -
Page 8: Ad-Dd Source Button
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. -

Page 12: The Da Source Button
If you want to use the ADDA 2408 for monitoring 5.1, you have to install one 4 channel D/A expansion card. (Use the monitor mixer to route channel 5 and 6 to the analog stereo output. -
Page 13: The Monitor Mixer
The Monitor Mixer Solo shortcut Pan shortcut The Monitor menu button The monitor Mixer can be used to mix down the 8 channels chosen at the DA Source button, into a stereo mix. At the Monitor mixer you can adjust output level, pan, solo, master level, solo level, and solo pre/post. For two channels at a time (1/2, 3/4, 5/6, or/and 7/8) it is possible to chose between a normal L/R output or a MS decoding of the signal. -
Page 14: Head Phone Amp
Head Phone Amp A high quality analog headphone amplifier with 1/4 inch jack is located on the front panel. The source for the headphone output is the stereo mix from the monitor mixer. The headphone output level on the front panel and the stereo XLR line connectors on the back panel, may be adjusted individually. -
Page 15: Sync Alarm
Sync alarm Sync alarm The ADDA 2408 can detect if the converter is in correct synchronization with your hard disk recording system. It is doing so by counting the incoming and outgoing samples on the digital I/O cards. If the connected hard disk recording system is not in sync with the converter, the sync alarm will light up and the LED for the digital interface at the DA source will flash. -

I/O modules A variety of expantion cards can be added to the ADDA 2408, including: * Dual AES3-S/PDIF digital I/O * 8 ch. AES3 digital I/O * 8 ch. TDIF digital I/O * 8 ch. ProTools Mix 24 compatible I/O * 8 ch. -
Page 19: The 4 Ch. Da Converter Interface
The 4 ch. DA converter interface One or two DA interfaces can be mounted in the ADDA 2408 for additional 4 or 8 ch.of analog outputs. The DADI/O-4DAC-XLR or the DADI/O-4DAC-XLR-L. On both cards the output line level can be adjusted to a reference level for 0 dBFS between + 12 and + 27 dBu via individual potentiometers on the modules. -
Page 20: The Protools Mix 24 Compatible I/O's
In the Hardware set-up menu of the ProTools system the ADDA 2408 is showing itself as an 888 /24 interface, and has to be set up as an 888 /24 interface. However the ADDA 2408 (888 /24 ) has to be set to internal sync in the ProTools menu. -

ADDA 2408 directly to the ProTools system with a normal 25 Pin D-Sub cable. It is also possibly to connect the ADDA 2408 to ProTools HD with a TDIF interface or a ProTools Mix 24 compatible interface, solely at 44.1 or 48 kHz. The ProTools Mix 24 compatible interface can be connected to the legacy port on the ProTools HD system. -

TDIF machine. Some old TDIF machines need Word Clock in order to run on ext. sync. Connect the WC out on the back panel of the ADDA 2408 to the WC in on the TASCAM recorder, set the ADDA 2408 to internal sync and set the TASCAM machine to WC sync. -
Page 23: The Adat Interface
The ADAT interface The ADAT I/O interface is a dual wire 96 kHz SMUX interface. If mounted in the ADDA 2408 it will identify itself as ADAT in the AD-DD source and the DA source menu. -
Page 24: The Aes,S/Pdif Interfaces
The AES,S/PDIF interfaces Two types of AES interfaces can be mounted in the ADDA 2408. An 8 channel AES I/O with a D-sub connector, or the stereo AES / S/PDIF / Optical S/PDIF interface. Both interfaces is single wire at 96 kHz.
