The D-911 VCA Fader Unit is designed to be used in
conjunction with the D-901 Digital Mixer. Connecting to the
D-984VC VCA Control Module permits volume adjustment
of all the channels and contact controls of the D-901 Mixer.
2. HANDLING PRECAUTIONS

modules mounted in the D-901 Digital Mixer. Connect
each of eight terminals to

1. Input volume controls
Adjust the volume of connected input equipment, such
as a microphone and CD player. Knob position 0
reduces the volume to its lowest setting and position 10
increases the volume to its highest setting.
2. Control keys
Used to recall preset memories or perform contact
controls. These keys light when the preset memory is
recalled or the contact turns on. (Functions can be
assigned to the contacts at the D-901.)
3. Remote (Activation) switch
Setting this switch to the ON position closes the Remote
(activation) output terminals on the rear panel, and
setting this switch to the opposite side opens the output.
4. Output volume controls
Adjust the output volume.
5. Name indication spaces

memory contents, and other features for convenience of
operation.
