An advance replacement program is also in place. For an additional fee an upgraded unit with 24-bit DACs will be
sent to the customer in exchange for their original unit(s).
Contact Digidesign Technical Support for the upgrade.

How can I use the 888/24 in Stand Alone mode & how can I tell if it is in Stand Alone mode?
To use your 888/24 as a ‘stand alone'24 bit Analog-Digital or Digital-Analog converter:
- Quit Pro Tools if it is launched.
- For Analog-Digital conversion, be sure to disconnect or turn off any external digital devices (DAT machines, effects
processors, etc.) that may be providing word clock information to the 888/24’s AES/EBU or S/PDIF channel 1 & 2
inputs.
- An AES/EBU (or S/PDIF -- see below) word clock signal is necessary for Digital-Analog conversion in Stand Alone
mode. Be sure to have a digital device providing word clock connected to the AES/EBU inputs 1 & 2 of the 888/24
interface.
In Stand Alone mode, the 888/24’s default word clock input port is AES/EBU, unless changed to S/PDIF via the
corresponding internal jumper setting. Please refer to the 888/24 I/O Installation Guide for specific instructions and
guidance.
To verify that the 888/24 is in Stand Alone mode:
- Check to see that the "analog" LED display for meters 1 & 2 is flashing. The LED flashes between a half-lit state to
full display.
-Turn off your CPU.

The default sample rate in Stand Alone mode is 44.1 kHz, how can I change that?
The factory default sample rate of the 888/24 is 44.1kHz. You can change this default sample rate to 48 kHz by
moving an internal jumper on the circuit board. This requires careful removal of the 888/24’s top cover and
physically moving the jumper corresponding to the desired sample rate.
Please refer to the 888/24 I/O Installation Guide for specific instructions and guidance.

Why are the inputs on my 888/24 distorting when connected to my Mix Farm card, but operate correctly
when connected to another audio card?
This is due to a change made in Revision N of the 888/24 that affected all interfaces through Revision Q.
Revision R fixes the problem. Contact Digidesign Tech Support for repair information.

Why am I getting clicks and pops when recording a digital input?
When 2 digital devices are connected via AES/EBU or S/PDIF and recording in either direction, a common clock is
required (For example: 1 device’s clock must be slaved to the other’s)
If you are recording into Pro Tools via the AES/EBU or S/PDIF inputs (such as a DAT or any other digital device),
the Sync Mode in the Hardware Setup window should be set to DIGITAL.
