Internal Mixer
Clicking on
Call Internal Mixer
in the
File
menu inside
External Links
will launch
the Windows Mixer (SNDVOL32.EXE) to control the
Internal Mixer
section of the
card.
The
Internal Mixer
on the DSP24 ADAT represents basically an additional
soundcard which has been 'added' to the audiocard functions. You can use this
section to play Windows sounds, or the metronome from a sequencer. You can also
use it for consumer applications such as games, or for internet phone usage. Since
the
Internal Mixer
even supports DirectSound, you can use it also for some
conventional software synthesizer applications. The Windows Mixer is used to
control these functions. These functions are represented by an AC-97 codec chip
that is on your DSP24 ADAT card. AC-97 has been defined as standard by Intel for
consumer audio applications on modern PCs. The AC-97 codec ST Audio is using
works with a 18bit ADC, a 18bit DAC and an analog mixer. The output of the
Internal Mixer
is audible via the analog monitoring output
only
.
Note that you would never use the
Internal Mixer
for high quality recording or
playback for music production. This means: if you have no need for consumer
audio applications (as mentioned above) or if you are using a separate consumer
soundcard in your PC for such applications, you would never use the
Internal
Mixer
and you can stop reading this section now. The
Internal Mixer
is a nice
addition to the main function set of the DSP24 ADAT card - not more, not less.
The following channels are available:
Master
Controls the
Master
output volume of the
Internal Mixer
. This signal is
sent out via the analog monitoring output.
Wave
Controls the
Wave
volume. The signal you play via the MME device
ADSP24 Int. WaveOut
(or
ADSP24 Int. Audio Device
) is controlled here.
Signals from pro audio applications (using ASIO or GSIF for example) are
not controlled by the
Internal Mixer
of course. By default this device is
selected as output for Windows system sounds under
Control Panel >
Multimedia > Audio > Prefered playback device
.
CD In
Controls the volume of the internal analog CD input (3-pin).
Aux
Controls the volume of the internal analog Aux input (3-pin).
