M-AUDIO Delta RBUS - Manual (Page 29)

or pops in the audio stream as some data may be lost. Larger buffers
cause slightly more latency but prevent the pops and clicks that might
occur with smaller buffer sizes – the default settings are recommended
but you may desire to tweak these default settings to suit your tastes.
This buffer size must be set in the Delta Control Panel before you launch
your music software. When using ASIO with the Delta R-BUS, set the
buffer size in the control panel, then exit the control panel. After doing so,
launch your music software.
VARIABLE OUTPUT LEVELS
The software switches in this section allow the user to match the Delta
R-BUS’ analog output levels to the operating signal levels of the external
audio equipment. Two level selections are available: ‘Consumer,’ and
–10dBV. The ‘Consumer’ setting is the least ‘sensitive’ of the two settings,
and ‘–10dBV’ the most sensitive. Therefore, the ‘Consumer’ setting has
more headroom and can accept the hotter signals of the two settings.
Consult the user guide of your external audio equipment regarding your
equipment’s input line level.
INPUT AUDIO SOURCE
The Delta R-BUS breakout cable includes inputs for both analog and S/PDIF
connections. However, only one of these inputs, either Analog or S/PDIF, may
be selected and used at one time. This section provides a software switch that
allows you to select between “SP/ANA Ports.” Selecting “S/PDIF” makes the
S/PDIF hardware input the active input. Selecting “Analog” makes the the
analog hardware inputs active. Remember that when S/PDIF is selected as the
Input Audio Source, “S/PDIF In” must be selected as the master clock,
otherwise no signal can be properly recorded at the S/PDIF input.
“DISABLE CONTROL” CHECKBOX
When running a music program that utilizes the Delta ASIO drivers, the
music program will take control of some of the Delta Control Panel
functions. Checking this checkbox will “Disable Control of the Monitor
Mixer and Patchbay/Router in Audio Applications,” namely, these ASIO
capable applications. Some programs interpret Direct Monitoring
differently, and may result in undesirable configurations for monitoring.
Emagic’s Logic program, in particular, will switch the Patchbay/Router
into “Monitor Mixer” mode when Logic is switched into record. You may
want to click on this switch when using Logic , thereby disengaging its
control over the Patchbay/Router.
ON THE MAC: The Hardware Settings Page in the Macintosh version of
the Delta Control Panel also contains software switches that allow you to
select which Delta input and output stereo pair will be used by the Sound
