About Burl Audio: Founded in 2006, BURL Audio is a pro audio gear engineering and manufacturing company located in Santa Cruz, California. Based out of Paradise Recording and spearheaded by Rich Williams, BURL Audio’s gear is designed in a commercial recording studio, by professional recording engineers, for recording engineers. The philosophy of BURL Audio is to provide the best possible recording devices, in modular outboard units, to all levels of recording engineers at a reasonable price.
B2 BOMBER ADC IN THE BOX: • • • • • • • • • • • • • B2 BOMBER ADC IEC Power Cable 4 Rack Screws with Washers B2 ADC FEATURES: 44.1 kHz to 192 kHz, 24 bit, 2 channel ADC Proprietary, high definition, BURL Audio BX1 transformer input All class-A, discrete transistors signal path with zero feedback, zero caps Audiophile quality 6 position attenuator with standard headroom settings High definition metering with simultaneous RMS and peak indication Dante, 2xAES, SPDIF and Toslink output, dual wire at 176.
B2 ADC FRONT PANEL CONTROLS: Figure 3 1 2 3 4 5 6 7 1. Input Level Attenuator- ***POST TRANSFORMER*** Allows quick selection between analog +4dBu = -12, -14, -16, -18, -20, -22 dBfs digital headroom. 2. Dual Wire- Sends LEFT to AES1, RIGHT to AES2 at 176.4kHz and 192kHz only. With Dual Wire off, L and R are sent over both AES1 and AES2. Dual Wire must be off for all sample rates other than 192/176.4 kHz. 3. High Resolution Meter- 30 segment meter shows RMS level and Peak simultaneously. 4.

L & R (with dual wire “off”), Ch. 1 (with dual wire “on” for 192kHz and 176kHz). 3. AES 2- Digital Output for Ch. L & R (with dual wire “off”), Ch. 2 (with dual wire “on” for 192kHz and 176kHzt). 4. TOSLINK- Digital Output for Ch. L & R. 5. S/PDIF- Digital output for Ch. L & R. 6.
B2 BOMBER ADC Getting Started: 1. Connect XLR cables to analog input. 3. Connect Word Clock cables if clocking via Word Clock (clocking via Dante, SPDIF or AES is also possible). 2. 4. 5. 6. 7. Connect desired digital output (Dante, AES, SPDIF or Optical). Set clock to Int. or Ext. (Internal clock recommended whenever possible). Set sample rate on front panel, when clock master. Select Dual Wire On or Off. Set input level. We recommend starting at -18 dbfs.
About Imagine the possibilities when all audio devices can be networked. Large facilities with multiple control rooms and studios can have easy access to each other. Imagine one control room runs out of outboard gear for a mix. No problem, route audio to the AD/DA in the next control room, utilizing its outboard gear. Need to use two studio main rooms with one control room? Easy, one DAW has total access to the other studio’s AD/DA.
About Dante Controller: Dante Controller is a software application provided by Audinate which allows users to configure and route audio around Dante networks. It is available for PCs running Windows 7 (SP1 and above), 8 and 8.1, and Apple Macs running OS X 10.7.5, 10.8.5 and 10.9.
DANTE QUICK START 1. Download and install “Dante Controller” and purchase “Dante Virtual Soundcard,” or Dante PCIe Card. Dante Virtual Soundcard -Go to www.audinate.com/products/software Dante PCIe Card -Focusrite Rednet PCIe card recommended 2. Using Cat6 Ethernet cable, connect the B2 Bomber to a gigabit switch. Connect your DAW computer to the same switch with CAT6 cable. For best results, start by removing all other connections to the switch. Dante should be on it’s own network. 3.
Figure 8: Example with 2 ADCs and 1 DAC 7. Click on DEVICE INFO, double click on B2 Bomber ADC/DAC (Figure 9, below). Figure 9: Example shows Device Info, with 2 ADCs and 1 DAC.
8. Click on DEVICE CONFIG. then select sample rate and select lowest latency (With the Dante PCIe Card, latency of 150 usec is possible. With the Virtual Sound Card, latency is 4msec). (Figure 10, below). Note: you will have to set sample rate for each device! Figure 10: Example shows Device Config for first ADC. Note: With multiple units, sample rate needs to be set for each unit, including the DAW. Note: Actual latency used between two endpoints is the larger of the two endpoint settings.
DANTE CLOCKING There are 3 ways to clock the B2 Bomber ADC/DAC with Dante: 1. B2 ADC/DAC set to Internal. Brooklyn II (BKII) card set to External (Recommended) 2. B2 ADC/DAC set to External Clock, BKII card set to External 3. B2 ADC/DAC set to Dante, BKII card set to Internal SEE FIGURE 12 (NEXT PAGE) FOR B2 INTERNAL CLOCKING DIAGRAM CLOCKING B2 BOMBER ADC/DAC TO INTERNAL WORD CLOCK: 1. 2. 3. 4. 5. 6.
