DFP-3000

B-Chain alignment is performed using the DFP-D3000, Setup Software, and your own test equipment. To
begin, connect your computer to the Decoder using a null modem cable, launch the Setup Software, and
“connect” the Setup Software to the DFP-D3000 using the Config>Connect to DFP… menus. Set up

your microphones and analyzer (THX R2 or other multichannel real time analyzer) in the theatre. Refer to
SMPTE Standard 202M, B-Chain Electroacoustic Response, for more detailed information on micro-
phone placement, theatre acoustics, and the “X” curve. Note that the DFP-D3000 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.

Open the Master DFP-3K Settings screen by select-
ing Master DFP-D3000 under the Master option in

the main screen menu bar.

Ensure that the Master Volume is set to 0.0 dB. Select
the appropriate output level for the DFP-D3000; this is
the absolute signal level that corresponds to the 

_20

dBFS reference point. In most cases you should chose
_10 dBu (145 mV).

Use your real time analyzer (RTA) to check the SPL in

the theatre and ensure that it is in the right range when

the Master Volume is 0.0 dB.

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.
