Audibax BSM100 - 100m Balanced Microphone Cable Reel (Silver Series, Black)

Audibax BSM100 - 100m Balanced Microphone Cable Reel (Silver Series, Black)

The Audibax Silver BSM100 reel offers 100 meters of professional balanced audio cable, designed for fixed installations and intensive live use. It features two OFC (oxygen-free copper) conductors, each with a 0.24 mm² cross-section and a 20 × 0.12 mm structure, ensuring stable signal transmission with low noise susceptibility. The cable is further enhanced with an OFC copper shield and internal paper/cotton layers for improved electrical and mechanical insulation. Its 6 mm outer diameter and flexible, durable PVC jacket facilitate routing, winding, and termination with standard connectors (XLR or TRS), while maintaining resistance to bending and pulling. Operating temperature range: -20°C to +70°C .

Product benefits

• Clean signal transmission thanks to OFC copper and copper shielding that reduces electromagnetic interference over long distances.
• Flexibility and resistance of the 6 mm PVC cover, designed for assembly, disassembly and guiding in conduits.
• Reliability in balanced connections (two conductors + shield), ideal for microphones, level lines and stage sends/returns.
• Easy termination on common connectors (3-pin XLR or 6.35 mm TRS jack), optimizing wiring times.
• Thermal versatility for working environments from -20 ºC to +70 ºC.

Use cases

• Fixed installation in auditoriums, conference rooms, temples, theaters or studios.
• Live sound and rental : microphone arrays, sub-machines, stage boxes and patch panels.
• Studio and broadcast : low loss balanced lines for preamps, interfaces and patchbays.
• Custom wiring and manufacturing of custom XLR/TRS patch cables.

Frequently Asked Questions

• Is it really a balanced cable? Yes. It has two internal conductors plus shielding, the standard topology for balanced microphone and line lines.
• Can it be terminated in XLR and TRS? Yes, its 6mm diameter and OFC construction make it compatible with standard 3-pin XLR connectors and 6.35mm TRS jacks.
• Is it suitable for DMX lighting? It's a balanced microphone cable. For DMX protocols, specific cables with a nominal impedance of 110 Ω are recommended.
• Does it withstand heavy use? The flexible PVC cover and copper screen provide good mechanical and flexural strength for frequent assembly and disassembly.
• Temperature range? It works between -20 ºC and +70 ºC.

Materials and construction

Oxygen-free copper (OFC) conductors minimize losses and oxidation, while the OFC copper screen provides continuous shielding against interference. Internal paper/cotton layers stabilize the assembly, reducing mechanical microphonic noise. The PVC jacket combines flexibility and abrasion resistance, facilitating installation in conduits and ducts.
