After another computer restart, a small BCA2000 control panel
icon appears in the task bar (Task Bar Notification Area). This
concludes the installation procedure.
2.3 ontrol panel software
The control panel soft are gives you access to all global
B-CONTROL settings and is integrated into your computer system
during driver installation. To launch the control panel soft are,
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, ith the exception of the Driver Latency/Buffer Size
setting: if you move the fader, a message pops up informing you
that the ne latency/buffer size setting ill be effective after
you close the control panel.
ADAT® 96 kHz operation is indicated in all indo s (right
field), along ith the current sample rate, ASIO and USB driver
version and firm are version.
The follo ing settings can be made in the Setup wind w:
Dig. 2-Ch. Output Format: The format for t o-channel digital
output is s itchable bet een 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 ordclock synchronization source.
DIG. 2-CH./ADAT enables external synchronization via the optical
or coaxial input ( hich input serves as the synchronization
source is determined by the DIGITAL IN button ( ). ADAT®
synchronization is only possible via the optical input ith 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
soft are.
MIDI Port B Select: In this field, MIDI OUT B can be configured
as a MIDI THRU. When THRU mode is activated, this output
for ards incoming data ith 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 hich signal is
monitored during recording. If Digital is selected, only the input
signal ill be heard ith no latency (delay). In Anal g mode,
both the recorded tracks and the input signal (the signal being
recorded) are heard simultaneously; the mix bet een the t o
can be adjusted via the MONITOR BALANCE fader ( ). In both
modes, only the output signal is heard hen the audio soft are
is in playback mode. S itching bet een recording and playback
mode is accomplished via your audio soft are.
Driver Latency/Buffer Size: Here you can adjust the latency
(system-inherent audio signal delay) in order to optimize your
computers performance. The lo er the latency (and
consequently the buffer size), the higher the CPU usage. When
the processor orkload is too high, you ill notice frequent
pauses in audio playback (as the processor catches up). If you
change this setting, a message ill appear stating that your
changes ill take effect only after you close the control panel.
The USB INFO wind w (fig. 2.2) allo s you to adapt the B-
CONTROL to the USB connection you are using. If you are running
your B-CONTROL on Full-Speed USB, only limited functionality is
available. The table sho s hich input/output combinations are
possible ith your USB interface.
The BLOCK DIAGRAM wind w (fig. 2.3) sho s the entire
audio signal flo of your BCA2000 and serves as a good source
of information if you dont have the users manual handy.

3. CONTROL ELEMENTS AND CONNECTIONS
The various control elements of your BCA2000 are described in this chapter. All controls and connections are explained in detail,
and there are several useful tips on their use.
3.1 ontrol surface
Fig. 3.1: The BCA2000s control elements
3.1.1 In ut section
The TRIM control adjusts the level of input signals.
The C IP and SIGNA LEDs sho the input signal level.
SIGNA illuminates hen there is an incoming signal,
hereas C IP illuminates hen the level is too high and
could cause distortion. If this happens, turn the TRIM control
counterclock ise slightly und the C IP LED no longer
illuminates.
The +48 V button activates phantom po er for a condenser
microphone connected to the XLR input.
+Be sure t mute y ur audi system bef re y u
activate the phant m p wer supply t prevent
audible and p tentially damaging switch- n thumps
fr m reaching y ur m nit r speakers.
PAN positions the signal in the stereo field. If the INE
STEREO button is pressed, the PAN control adjusts
the BA ANCE bet een L and R signals in the stereo input
channel.
The 100-mm channel faders control the level of the input
signal that is routed to the A/D converter.
MIC A and INE are the t o possible positions of this
s itch, hich controls the input that is routed to a particular
channel. The corresponding LEDs indicate the input you
selected. If GUITAR HI-Z s itch is pressed, the left
MIC A/LINE L s itch is deactivated.
The GUITAR (HI-Z) button feeds the guitar signal from the
guitar input into the mono input channel. This button
overrides the MIC A/LINE L button : hen GUITAR
(HI-Z) is activated, MIC A or LINE L can no longer be
selected.
The GUITAR IN (HI-Z) input allo s you to directly connect
an electric guitar or other high-impedance signal
(e.g. passive pickups of acoustic instruments).
MIC B/ INE R is the input selection button for the stereo
input channel. Select bet een MIC B and INE R (the right
line input). The corresponding LEDs indicate the selected
input.
3. CONTROL ELEMENTS AND CONNECT ONS

9
B-CONTROL AUDIO BCA2000
The INE STEREO button feeds the stereo signal of both
line inputs ( ; see page 10) into the stereo input channel.
If the LINE STEREO button is pressed, channel t o
becomes a stereo channel, and the PAN control assumes the
BALANCE function (see 4 above). This allo s a maximum of
three input signals (1 x mic/guitar and 1 x stereo) to be processed
simultaneously (see also ch. 4.1).
3.1.2 Main/Monitor section
The 100-mm MAIN fader controls the output signal
(MAIN OUT).
The PHONES controls adjust the volume of connected
headphones.
The CTR ROOM control adjusts the volume of the control
room outputs .
The PHONES outputs (individually adjustable; see 12) are
used for connecting headphones. You can listen to the
main output, the input sum or the mix of both signals.
The MONITOR button activates the direct monitoring
function, and the DIR I/O LED lights up. When the button is
not pressed, auto monitoring is active.
With auto monitoring, s itching bet een input and recorded
tracks is done automatically by your host soft are (audio
sequencer/soft are mixer). System-induced latencies occur
bet een the recorded signal and computer playback. To avoid
this, you can s itch to DIRECT I/O during a recording session.
This provides you ith delay-free signal routing (see also ch. 4.3).
ISTEN s itches the monitor signal (control room and
phones) to mono (e.g. to check mono compatibility).
DIM lo ers the level of phones and control room outputs
by -20 dB.
The MUTE button mutes the phones and control room
outputs.
The MONITOR BA ANCE control adjusts the volume
balance bet een the input sum and the output signal (main
out). The control is only active if the MONITOR button
is pressed (direct monitoring).
The AUDIO ROUTING diagram sho s the audio signal
flo of your B-CONTROL. The integrated LEDs sho the
current selection of inputs and the status of buttons - .
The DIGITA IN button lets you select a digital input source
(COAXIAL or OPTICAL).
OPTICA OUT selects the format for the optical output
. Available choices are ADAT (eight-channel or four-
channel ith ADAT S/MUX) and 2-CHANNEL.
CH. 1-2/CH. 7-8 button: if OPTICAL OUT is set to
2-CHANNEL, the CH. 1-2/CH. 7-8 button lets you select
hich USB output channels are played back via the digital
optical and coaxial outputs. If OPTICAL OUT is set to ADAT,
the CH. 1-2/CH. 7-8 setting only applies to the coaxial output.
The status LEDs for buttons to are located in the
audio routing diagram .
SAMP E RATE LEDs: All digital inputs and outputs have
the same sample rate, hich is determined by your host
soft are (unless you are synchronizing to an external
ordclock source). If you change the sample rate in the
soft are, the display on your BCA2000 automatically
s itches to the ne value. For example, if you select
44.1 kHz in your soft are, the 44.1 kHz LED illuminates. If
an external ordclock signal is connected, the DIGITA
IN LED illuminates. If this external signal also has a sampling
rate of 44.1 kHz, both the 44.1 kHz and the DIGITA IN
LEDs ill illuminate.
The METER button lets you s itch the LED level meters
( and ) bet een input and output signals.
The LED level meter displays either the input sum signal
post-A/D converter or the digital output signal pre-main
fader, depending on the position of the METER button .
The LEDs for channels 3 - 8 indicates signal presence in
the digital channels 3 - 8 (green SIG LEDs) or if levels are
too high and may cause distortion (red C IP LEDs).
These status LEDs display the follo ing:
MIDI IN, OUT A and OUT B illuminate if MIDI signals are
present at the respective connectors.
USB FU and USB HIGH LEDs indicate status and type of
the USB connection. The appropriate LED ill remain
illuminated as long as your BCA2000 is connected to your
computer via USB (and the computer is po ered up).
3.1.3 Dynamics section
Your BCA2000 features a combined noise gate/limiter
(dynamics) section for the analog input signal. This section is
located directly pre-A/D converters.
The ON button activates the dynamics section.
The NOISE GATE control adjusts the threshold or signal
level belo hich the noise gate is activated; signals belo
this level are muted. Turning the NOISE GATE control fully
counterclock ise (-∞) deactivates the noise gate.
When the level of a signal falls belo the threshold value,
this red THRESHO D LED illuminates (noise gate active).
The limiter limits the signal to a maximum level, hich can
be adjusted. Turning the IMITER control fully clock ise
deactivates the limiter.
The IMIT LED illuminates hen the limiter is active.
+If y u nly want t use the n ise gate, set the
LIMITER c ntr l t zer (fully cl ckwise). If y u nly
want t use the limiter, turn the NOISE GATE c ntr l
t -¥ (fully c untercl ckwise).
+The n ise gate/limiter secti n w rks in fixed
stere , i.e. the left and right channels always
functi n j intly. When pr cessing tw m n signals,
these signals may be pr cessed inaccurately.
