M-AUDIO DELTA 66 - Manual (Page 24)

VARIABLE SIGNAL LEVELS: The software switches in this section allow the user
to match individual input levels and global (as in ‘all’ or ‘across the board’) output
levels to the operating signal levels of the external audio equipment. Three level
selections are available: +4dBu, ‘Consumer,’ and –10dBV. The ‘+4dBu’ setting is
the least ‘sensitive’ of the three settings, and ‘–10dBV’ the most sensitive.
Therefore, the ‘+4dBu’ setting has the most headroom and can accept the hottest
signals of the three settings.
Consult the user guide of your external audio equipment regarding your equipment’s
line level. If for instance your audio equipment is consumer or semi-pro, and you
find that its input level is a little too hot for the Delta 66’s ‘-10dBV’ setting, try
switching to the ‘Consumer’ setting. Conversely, if your –10dBV gear is receiving
a signal from the Delta 66 that is too hot, try switching the Delta 66’s output levels
from ‘Consumer’ to the ‘–10dBV’ setting.
S/PDIF Page
The S/PDIF page of the Delta Control Panel configures the S/PDIF output format
and displays the status of the S/PDIF input. To display this page, click the “S/PDIF”
tab of the Delta Control Panel software.
DIGITAL INPUT: This group box displays the current S/PDIF input status. The
Delta 66’s S/PDIF receiver is capable of recognizing a valid input signal versus an
invalid, corrupt or non-present one. When a valid signal is detected at S/PDIF In,
this group box displays “Valid Input Detected.” When an invalid signal is detected
or no signal is present, the group box displays “Invalid or Not Present.” Below this
