5. B-Chain Alignment.
B-Chain alignment is performed using the DFP-D2500, Setup Software, and your own
test equipment. To begin, connect your computer to the Decoder using a null modem
cable, run the Setup Software, and "connect" the Setup Software to the DFP-D2500
using the Config>Connect to DFP... menus. Set up your microphones and analyzer in
the theater. Refer to SMPTE Standard 202M, B-Chain Electroacoustic Response, for
more detailed information on microphone placement, theatre acoustics, and the "X"
curve.
Note that the DFP-D2500 must be set up with the Master Fader nominally set to 0.0 (not
7) and that from this position 10 dB of boost and full cut is available, with an audio/dB
fader taper.
1. Move all Channel Level Trims to the
center setting (0.0 dB). Center all
equalizer sliders at 0.0 dB. To quickly
set all EQ levels to 0.0 dB, access the
Reset Channel function in the Tools
pull-down menu located in the main
screen menu bar. The illustration shows
the main screen of the Setup Software
in this condition, for the Left output
channel.
2. Link the channel mutes to the
channel selects using the Tools
selection of the main screen and
selecting Link Mute Channels to
Channel Select.
3. To bring up the DFP Test Signal
Generator screen, select the Signal
Generation option under the Test
item on the main screen menu bar.
