of all the channels and contact controls of the D-901 Mixer.
2. HANDLING PRECAUTIONS
• The D-911 Fader Unit is connected to the VCA control
modules mounted in the D-901 Digital Mixer. Connect
each of eight terminals to

the same name by way of
the fully-connected straight
cable as shown on the
right.
• Use the D-901 firmware of version 3.0 or later. Firmware
versions earlier than it cannot be used in conjunction with
