1. INTRODUCTION
Welcome to the family of BCA2000 users and thank you for expressing your confidence in BEHRINGER products by purchasing the B-CONTROL.
The BCA2000 is an extremely flexible USB audio and MIDI interface with a unique design concept that will effectively support you in your computer-based music and audio endeavors.
Our goal in designing the B-CONTROL was to create an intuitive, flexible and optically attractive product that gives you comfortable control (instead of those tiny knobs and buttons found on so many interfaces) and plenty of connectivity options, so that you can concentrate on what’s really important: your music. That’s why we started by creating a mixing console with a clean, concise layout: ultra-precise 100-mm faders, a highresolution LED level display, rugged construction, our ultra lownoise IMP “invisible” microphone preamplifiers and an extensive monitor section—features you’ve come to expect from a BEHRINGER mixing console. Then we added a multitude of interface functions: full 24-bit/96 kHz support in multichannel operation, optical and coaxial digital connectors that support all common formats, simultaneous reproduction of eight input and eight output channels, 6 analog outputs for subgroup/stem or 5.1 surround reproduction and a simultaneously usable USB MIDI interface. All of this makes the BCA2000 a one-of-a-kind high-speed USB audio/MIDI interface featuring a comfortable mixing console design.

2.INSTALLATION
2.1Driver installation—Part 1
Start your Windows® XP computer and insert the BEHRINGER driver CD.
Install the Microsoft Hotfix Patch:
sIn Windows Explorer, select the CD/DVD drive in which the BEHRINGER driver CD is located
sOpen the “KB822603” folder
s Double-click the command file in your language (e.g. “English.CMD”)
sFollow the instructions in the dialog box by clicking “Next >”
sAfter the final step, click “Finish”. The computer will now restart.
2.2 Hardware connection/ driver installation—Part 2
Connect your computer via USB to the BCA2000 and power up the B-CONTROL. The “Found New Hardware Wizard” opens up.
sSelect “Install from a list or specific location (Advanced)” and click “Next >”
sSelect “Search for the best driver in these locations”
sCheck the “Include this location in the search” box and click “Browse”
sSelect the CD/DVD drive with the BEHRINGER driver CD and the folder “Drivers”* and click “Next >”
sIf you now get an error message (“Driver software has not passed Windows Logo testing”), ignore the message and click on “Continue anyway” (whether or not you get the error message depends on the configuration of your computer)
sAfter software installation is complete, the “Behringer BCA2000 bootloader” prompt appears; click “Finish”.
The “Found New Hardware Wizard” will automatically start again. This procedure is almost identical to the previous one:
sSelect “Install from a list or specific location (Advanced)” and click “Next >”
sSelect “Search for the best driver in these locations”
sSelect the “Include this location in the search” box and click “Browse”
sSelect the CD/DVD drive with the BEHRINGER driver CD and the folder “Drivers”* and click “Next >”
sIf you get the same error message again (“Driver software has not passed Windows Logo testing”), ignore the message and click on “Continue anyway” (again, whether or not you get the error message depends on the configuration of your computer)
sAfter software installation is complete, the “BEHRINGER BCA2000” prompt appears; click on “Finish”.
After another computer restart, a small BCA2000 control panel icon appears in the task bar (“Task Bar Notification Area”). This concludes the installation procedure.
*If you downloaded the driver from the internet, you will first need to decompress the file. During installation, select the location on your hard drive where you saved the decompressed driver.
2.3 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.
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.
The USB INFO window (fig. 2.2) allows 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 shows which input/output combinations are possible with your USB interface.
The BLOCK DIAGRAM window (fig. 2.3) shows the entire audio signal flow 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 Control surface
Fig. 3.1: The BCA2000’s control elements
3.1.1 Input section
The TRIM control adjusts the level of input signals.
The CLIP and SIGNAL LEDs show the input signal level. SIGNAL illuminates when there is an incoming signal, whereas CLIP illuminates when the level is too high and could cause distortion. If this happens, turn the TRIM control counterclockwise slightly und the CLIP LED no longer illuminates.
The +48 V button activates phantom power for a condenser microphone connected to the XLR input.
+Be sure to mute your audio system before you activate the phantom power supply to prevent audible and potentially damaging switch-on thumps from reaching your monitor speakers.
PAN positions the signal in the stereo field. If the LINE STEREO button 
is pressed, the PAN control adjusts the BALANCE between 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 LINE L are the two possible positions of this switch, which controls the input that is routed to a particular channel. The corresponding LEDs indicate the input you selected. If GUITAR HI-Z switch 
is pressed, the left MIC A/LINE L switch 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 
: when GUITAR (HI-Z) is activated, MIC A or LINE L can no longer be selected.
The GUITAR IN (HI-Z) input allows you to directly connect an electric guitar or other high-impedance signal (e.g. passive pickups of acoustic instruments).
MIC B/LINE R is the input selection button for the stereo input channel. Select between MIC B and LINE R (the right line input). The corresponding LEDs indicate the selected input.
