CDSVAN Digital Conference Solution
The B8 AD/DA Break-Out-Box
Description
The B8 is your interface to the digital world and of course, vice versa.
The B8 AD/DA interface offers you a high quality audio conversion from analogue to digital (AD) and digital to analogue (DA) in one single 2HU housing. Almost all digital sound processing systems offer a large amount of digital channels, but due to space restrictions the AD/DA conversion has to be outsourced, if more channels are required.
At this point the B8 starts its work. Feed in the analogue signals, using the analogue input sockets at the rear side of the B8. Depending on the available patch cable, either XLR or ¼ inch jacks can be used.
All inputs are electrically balanced to avoid electromagnetic interference (transformer balanced version available on request).
The B8 operates line and microphone level signals. The 8 inputs are individually adjustable to the level of the incoming signal. Even phantom power is provided by the B8 and switch able to all microphone inputs. High quality microphones (e.g. condenser microphones) can be connected directly to the B8 without any additional power supply. All input channels are equipped with individual level adjustment of +/- 9dB. All level are easily adjusted and saved by the use of a software interface within CDSVAN or any common MIDI tool
– no extra cabling and tiny knobs or buttons are required.
To deliver you the best audio performance the analogue-to-digital conversion works with a 24 Bit resolution and selectable sample rates of 32, 44.1 or 48 kHz.
The B8 offers the common digital multichannel interfaces ADAT® and of course an interface to the CDSVAN system – EDAT.
With the EDAT (RJ45) connectors the number of in- and outputs can be extended to 16, linking a second B8 to the first one.
The B8 can also be used as a digital 32 channel (16 channel in and 16 channel out) audio distributor independently of the CDSVAN conference system.
Operating Controls
Front view
-
The front side of the B8 is equipped with 3 LED’s per channel to indicate the following items:
- MIC or LINE level selected (MIC if red)
- AF –(Green LED) audio signal available at analogue input
- PEAK (Red LED) indication for maximum audio level
- Phantom power for all microphone level inputs.
- A Power switch with “power-ON” LED is dedicated on the right hand side of the front panel.
Rear view
- 8 analogue inputs XLR/ ¼”
- 8 analogue outputs XLR
- Main power connector
- Ground connector
- 2 EDAT (RJ45) sockets for VAN I/O and LINK
- 3 ADAT® sockets for ADAT IN, OUT and TRU
- Wordclock connector (BNC)
- MIDI IN and OUT
- 12 DIP switches for B8 set-up
Audio Control
All audio settings concerning the sensitivity of the analogue inputs of the B8 are done via the CDSVAN software:
Using the B8 Control, all inputs at the B8 can be individually switched to microphone or line level. For a smooth adjustment to the signal source, the B8 Control is equipped with a rotary knob for each channel to in- or decrease the input level with +/- 9 dB.
