D-911 VCA FADER UNIT
Thank you for purchasing TOA's D-911 VCA Fader unit.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.
1. GENERAL DESCRIPTION
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
• 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 D-984VC's terminal of
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
the fader unit.
The firmware version number can be confirmed on the D-
901's front panel-mounted display.

If your firmware version is old, download the latest
software program and the "D901 PC software instruction
manual" from the TOA Internet product data site
[http://www.toa-products.com/]. For the update
procedure, refer to the instruction manual.
• For channels with stereo link or group settings
established at the D-901, the lowest numbered channels
in the stereo linked or grouped channels are enabled.
• Control's knob position 10 of the D-911 provides the
channel gain set by the D-901. As a guide, knob position
8 provides about 10 dB below the gain set by the D-901.
