Phonic IS16v1 Manual Del Usuario página 37

Input Channels
The Input Channels section allows users to view and edit the name
of the various input channels received from the USB/FireWire input.
Output Channels
By entering the Output Channels section, users can view and edit
the names of the sixteen return channels from the computer to
the IS16 digital mixer.
Synchronization
In the Synchronization section, users can adjust the sampling rate
and other synchronization properties. Many of these adjustable
properties, as they are, are set for optimum performance and,
unless you are sure of what you need to change, are probably
best left alone.
First off, the synch mode can be altered, though making this
alteration is not recommended for novice users. The sync mode
is basically the way the computer determines what the 'clock
source' (ie. device that your computer will use to determine the
timing of all digital signals received) will be. The default setting
for this feature is "CSP", meaning the IS16 is the "master" clock
source of the device. The other options allow users to make the
IS16 follow the "timing" of whichever device is the clock source.
IS16
Having two clock sources has the potential to cause undesireable
results to your audio, so it is best avoided. If the IS16 is the only
piece of digital audio equipment attached to the computer, there
is no reason this option should be changed.
Users are also able to change between automatic and manual
sampling rate settings. When the sampling rate is manually set,
users can select between sampling rates of 44.1, 48.0, 88.2 and
96.0 kHz per second. Many devices have sampling rates that do
not surpass 44.1 kHz per second, therefore, when using multiple
digital devices, users are advised not to exceed this level unless
they are sure the secondary device's sampling rate can match
the sampling rate.
Settings
Users are able to adjust various buffer times in the Settings
section. The Stream Buffer Depth is adjustable between 0.5 and
20 milliseconds. It adjusts the buffer used when streaming a signal
from the IS16. If the depth is set too high, an obvious latency will
become evident. If the depth is too low, various clicks and pops
may become obvious. It is best to set the Stream Buffer Depth
to a level that allows users to get the lowest latency, while still
maintaining an optimal performance. The default settings are ideal
for most computers.
The ASIO Buffer Depth is adjustable between 4 and 40
milliseconds. This allows users to adjust the latency of the stream
received by ASIO driver-based software (including Steinberg
Cubase LE).
The WDM (Windows Driver Model) Sound Buffer Depth is
adjustable between 4 and 40 milliseconds. This allows users to
adjust the latency of the stream received by WDM based programs.
Also in this section, users are able to view their "drop out statistics",
where the number of times either the USB or FireWire connections
have been interrupted can be viewed.
Streams
In the Streams section, the IS16 device properties can be
viewed. Each input and output stream can be scrutinized, and
the isochronous stream number and its supported sampling rates
can be viewed.
