THE FIBER FUTURE MADE AFFORDABLE
FIBOX FBAI-M
TWO CHANNEL ANALOG MASTER INPUT MODULE
The introduction of Fibox marks an extraordinary
breakthrough in the transmission of audio signals. For
the first time, all the advantages of 20-bit, full-bandwidth
digital fiber-optic transmission are available at cost levels
easily accessible to virtually any professional audio or
broadcast application – from the network teleproduction
facility down to the neighborhood church.
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 ideal 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
continuously 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 62.5/125µ multimode fiber with conventional ST
connectors, assuring ease of use and fast set-up 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 SYSTEM: CLEAR ADVANTAGES
• No line loss
• No ground loops
• Inherent immunity to EMI and RFI
• High common mode rejection ratio (CMRR)
• 20-bit A/D and D/A conversion: 108dB dynamic range
• 48kHz sampling
• Transmission distances up to 4km (2.5 miles)
• Modular design: expandable from 2 to 12 channels
on one fiber
• Analog or AES/EBU digital output
• Data interface for transmission of SMPTE,
RS232/422/485, MIDI
• Easy installation and field set-up
A complete Fibox system comprises one or more Input
modules, one or more Output modules (either analog or
AES/EBU digital), plus fiber-optic cabling and any required
power supplies, linking cables, and rack mounting
hardware. This data sheet contains detailed information
on Analog Input modules only.
Actual size.
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.
Available in master and slave models.
