Fibox FBAI-M
Two Channel Analog Master Input Module
Download Specs
In one compact unit, the FBAI-M incorporates a two-channel preamplifier, 20-bit delta-sigma A/D converters, a digital multiplexer, and a fiber optic transmitter. The FBAI-M accepts either microphone-level or line-level signals on balanced XLR inputs. The microphone preamplifier offers performance comparable to the finest studio mixing consoles, making the FBAI-M idea for extremely demanding applications such as direct-to-digital remote recording of classical music. Phantom powering (48V) is provided for condenser microphones, selectable on/off with a front panel switch.
Also on the front panel, each channel of the FBAI-M is provided with a Mic/Line input selector switch, a continuosly variable gain control (4 to 70dB boost in "Mic" position only), and "peak" LED to indicate input overload. A rear panel input polarity ("phase") reversal switch is provided for channel 1.
Output of the FBAI-M is standard 1310nm wavelength on 62.5/12µ multimode fiber with conventional ST connectors, assuring ease of use and fast setup in the field or on the sound stage. A DB-15 multipin connector is provided to link the FBAI-M with up to five additional FBAI-SL slave units using the LKI-6 linking cable.
Fibox FBAI-SL
Two-Channel Analog Slave Input Module
The FBAI-SL is identical to the FBAI-M except it does not contain circuitry or connectors for fiber optic transmission. Instead, the digital audio output of the FBAI-SL is fed through a linking cable to an FBAI-M master unit. A single FBAI-M master can accept, synchronize, and multiplex audio signals for up to five additional slaves, thus providing 12-channel capability on a single fiber
link.
