\n
OPTAV bidirectional Balanced Audio over Fiber extenders deliver professional broadcast-grade audio transmission. Above all, this full product lineup covers 1 to 32 audio channels to match diverse studio and venue demands. Meanwhile, every unit adopts lossless full-digital encoding without any audio compression. In turn, it preserves original sound details without signal distortion or quality loss. Besides, the hardware supports 24bit\/96KHz high-fidelity sampling to restore rich, clear audio tones. Therefore, this Balanced Audio over Fiber solution works reliably for stages, broadcast studios, conference centers and large audio engineering projects. Furthermore, users gain true plug-and-play operation with zero driver setup for fast on-site deployment.<\/div>\n<\/div>\n
\n

Core Advantages of Balanced Audio over Fiber<\/h2>\n<\/div>\n
\n

1. Flexible Channel & Transmission Direction Options<\/h3>\n<\/div>\n
\n
First of all, this Balanced Audio over Fiber series supplies complete channel selections from 1CH up to 32CH balanced audio streams. Specifically, each model splits into one-way and two-way bidirectional transmission versions for different audio signal flow needs. Next, small-scale projects can pick 1CH\/2CH models such as OV11CA-1W and OV11CA-2W. To be precise, large broadcast venues can select 8CH, 16CH or 32CH units for multi-channel audio routing. On top of that, all variants adopt standard XLR balanced audio ports to fit mainstream professional audio devices. As a result, installers match mixers, microphones and speakers without extra adapters. Importantly, the series supports 16-bit digital encoding to meet standard broadcast audio requirements. For this reason, it delivers stable, interference-free audio signals across all transmission distances.<\/div>\n<\/div>\n
\n

2. Dual Fiber Mode & Multiple Distance Coverage<\/h3>\n<\/div>\n
\n
When it comes to optical transmission performance, this Balanced Audio over Fiber kit accepts multiple optical connector types. Correspondingly, buyers choose LC, SC, FC or ST fiber ports to fit existing cabling infrastructure. Even better, the dual-wavelength optical design uses 1310nm plus 1470~1610nm laser wavelengths for steady bidirectional signal delivery. Meanwhile, multimode fiber supports transmission up to 500 meters for indoor short-distance layouts. In effect, single-mode fiber extends signals to 20KM, 40KM, 60KM, 80KM, 100KM or 120KM for cross-building long-distance audio delivery. Fiber transmission fully blocks EMI and RFI noise from power equipment. In turn, it eliminates hum, static and audio dropouts common in copper cable wiring.<\/div>\n<\/div>\n
\n

3. Metal Housing, Low Power & Stable Hardware Design<\/h3>\n<\/div>\n
\n
In terms of structural design, every transmitter and receiver uses solid black metal casing. Moreover, the metal shell improves heat dissipation and extends long-term service life. The compact size simplifies rack mounting and hidden equipment cabinet installation. Separately, the plug-and-play hardware skips complicated software configuration. Thereby, field technicians finish wiring and signal testing within minutes.<\/div>\n<\/div>\n
\n

4. Wide-Range Temperature Adaptability<\/h3>\n<\/div>\n
\n
Last but not least, this Balanced Audio over Fiber extender adapts to various indoor and semi-outdoor working environments. In particular, it maintains stable audio performance at operating temperatures from -20\u00b0C to 50\u00b0C. In practice, it stores safely between -40\u00b0C and 85\u00b0C during off-season transport or equipment storage. Consequently, users avoid extra temperature control gear for event venues, broadcast studios and industrial audio control rooms.<\/div>\n
