B-CONTROL AUDIO BCA2000
1.2.2 Outline of functions for Full-Speed USB
Audio inputs:
s Simultaneous recording of three analog signals (1 x mono,
1 x stereo) and one stereo digital signal.
s Alternatively, simultaneous recording of four ADAT ® channels
at 44.1 and 48 kHz.
s Support of S/PDIF, AES/EBU and ADAT ® digital audio formats.
Audio outputs:
s Simultaneous reproduction of two stereo signals, available
in parallel on the analog and digital outputs.
s Alternatively, reproduction of four ADAT
®
channels at 44.1
kHz or 48 kHz via the optical output, also available in parallel
on all analog outputs and on the coaxial digital output.
s Support of S/PDIF, AES/EBU, ADAT ® , DOLBY ® DIGITAL and
DTS
®
digital audio formats.
MIDI:
s Additionally, simultaneous use of all MIDI functions.
2. INSTALLATION
2.1 Hardware connection and
driver installation
s Before you start the setup.exe program, close all
applications, including any virus scanners
s Via a USB port, connect the BCA2000 to your computer.
However, do not yet power up the B-CONTROL!
s Unzip the setup.zip file. To start the installation process,
double click the setup.exe icon. Then, follow the on-
screen instructions!
+
Before you continue, switch off the BCA2000. At the
appropriate step of the installation process,
setup.exe will prompt you to switch on the BCA2000.
If you opened “Found New Hardware Wizard”, close
this wizard.
+
Although setup.exe repeats the installation process
for each driver, setup.exe guides you through each
step of the relevant installation processes.
+
If the message “Driver software has not passed
Windows ® -Logo testing” appears during the
installation process, ignore this message and click
“Continue installation”.
2.2 Control panel software
The control panel software gives you access to all global
B-CONTROL settings and is integrated into your computer system
during driver installation. To launch the control panel software,
click on the BCA2000 control panel symbol in the task bar at the
bottom right of your screen.
Any changes to settings in the control panel are immediately
effective, with the exception of the “Driver Latency/Buffer Size”
setting: if you move the fader, a message pops up informing you
that the new latency/buffer size setting will be effective after
you close the control panel.
ADAT
®
96 kHz operation is indicated in all windows (right field),
along with the current sample rate, ASIO and USB driver version
and firmware version.
SETUP window:
Fig. 2.1: Control panel software SETUP window
The following settings can be made in the Setup window :
Dig. 2-Ch. Output Format: The format for two-channel digital
output is switchable between AES/EBU and S/PDIF . Format
selection has an effect on both the coaxial and the optical output,
unless the OPTICAL OUT button ( ) is set to “ADAT”.
Clock Select: Selects a wordclock synchronization source. DIG.
2-CH./ADAT enables external synchronization via the optical or
coaxial input (which input serves as the synchronization source
is determined by the DIGITAL IN button ( ). ADAT
®
synchronization is only possible via the optical input with an
ADAT
®
signal present. To synchronize to a 96 kHz signal, select
S/MUX (ADAT IN) . When set to INTERNAL , the BCA2000
synchronizes itself to the sample rate selected in your audio
software.
MIDI Port B Select: In this field, MIDI OUT B can be configured as
a MIDI THRU. When THRU mode is activated, this output forwards
incoming data with no additional processing. If OUT is selected,
the OUT B/THRU connector can be addressed by the computer
as a second MIDI output, giving you a total of 32 MIDI channels.
ASIO Direct Monitoring: This setting determines which signal is
monitored during recording. If Digital is selected, only the input
signal will be heard with no latency (delay). In Analog mode,
both the recorded tracks and the input signal (the signal being
recorded) are heard simultaneously; the mix between the two
can be adjusted via the MONITOR BALANCE fader ( ). In both
modes, only the output signal is heard when the audio software
is in playback mode. Switching between recording and playback
mode is accomplished via your audio software.
Driver Latency/Buffer Size: Here you can adjust the latency
(system-inherent audio signal delay) in order to optimize your
computer’s performance. The lower the latency (and
consequently the buffer size), the higher the CPU usage. When
the processor workload is too high, you will notice frequent
pauses in audio playback (as the processor catches up). If you
change this setting, a message will appear stating that your
changes will take effect only after you close the control panel.
