GUIDE TO INSTALLATION AND OPERATION

62 | DAP-1781

Miscellaneous

Tone generator 1 kHz sine wave interrupted on left channel (250 ms / 3 s)

EBU R49

Signal presence threshold from –72 to –48 dBFS (6 dB steps)

No signal delay from 0 to 255 s (1 s steps)

Fixed delay 0 to 2.4 s

Steps: ms (coarse) & sample (fine)

Tracking delay 0 to 8 video frames

GPI inputs (via A-BUS only) The GPI information is transmitted to the DAP-1781 at the

switch line. The User Preset Load command needs less

than a frame (about 28 ms) to be completed.

Note that this time will increase when a Dolby module is

installed: about a frame for each modified parameter inside

the Dolby module.
