Belden XLR Male-to-Female Cable, 15 Metre

Belden XLR Male-to-Female Cable, 15 Metre

The Belden XLR Male-to-Female Cable is a 15 metre balanced audio lead with a male XLR connector at one end and a female XLR connector at the other. That male-to-female arrangement is the standard form of a microphone cable: the female end connects to a microphone or to the output of a DI box or stage box, and the male end connects to a mixer, audio interface, stage box input or powered speaker. At 15 metres, it is a long run cable, suited to stages, halls and studios where the performer or microphone position sits well away from the mixing position. Belden is one of the long-established names in professional broadcast and audio cabling, and a ready-made lead of this type saves the time and variability of assembling a cable by hand.

Key features

• 15 metre length for long microphone and line-level runs
• Male XLR connector at one end, female XLR connector at the other
• Standard 3-pin XLR configuration used across professional audio
• Balanced connection for noise rejection over long distances
• Suitable for microphones, mixers, PA systems and stage boxes
• Single ready-made cable assembly, ready to connect

Why balanced XLR matters on a long run

An unbalanced cable carries the signal on one conductor referenced to ground, so any electrical noise picked up along the cable is added directly to what you hear. A balanced XLR connection carries the signal on two conductors, one of them inverted, inside a shield. Interference that affects both conductors equally is cancelled at the receiving input, a principle called common-mode rejection. Over a short desktop run the difference may be minor, but across 15 metres of stage, passing lighting dimmers, power cables and air-conditioning circuits, balanced wiring is what keeps a microphone signal clean. That is why XLR in this 3-pin format remains the default connection for microphones and professional line-level equipment worldwide.

Where a 15 metre lead earns its place

Fifteen metres reaches from a vocal microphone at the front of a stage back to a mixer at the side, from a drum kit or backline position to a stage box, across a hall for a speech microphone at a lectern, or from a studio live room to a control room wall box. Houses of worship, schools, conference venues and function bands all keep long XLR leads in the cable trunk for exactly these layouts. The same cable also works for line-level balanced signals, such as connecting a mixer output to a powered loudspeaker some distance away, provided the equipment at both ends uses XLR connections. Keeping one or two long leads alongside shorter patch cables covers most layouts without joining cables together, and every join avoided is a potential fault and noise source removed.

Handling and care for long cables

Long cables last when they are coiled and stored properly. Use an over-under coiling technique so the cable lies flat without twists, secure it with a tie, and avoid tight bends at the connector, which is where conductors fatigue. When running the cable across a walkway, tape it down or use a cable ramp so it is not crushed by feet, chairs or flight cases rolling over it. Keep long parallel runs alongside mains power cables to a minimum where the layout allows, crossing power at right angles when crossing is unavoidable. Before an event, test the full run with the actual microphone and mixer, listen for hum, crackle or intermittent dropouts while gently moving the cable near each connector, and swap in a spare if any fault appears.

Compatibility

The 3-pin XLR connectors fit the microphone inputs and balanced line connections found on mixing consoles, audio interfaces, PA amplifiers, powered speakers, stage boxes and microphone preamplifiers from all major manufacturers. Dynamic and condenser microphones both use this connection, and phantom power from a mixer passes through a standard balanced XLR lead to a condenser microphone that requires it. The cable does not convert between formats: equipment with jack or RCA connections needs its own appropriate lead or adapter. Checking that both the source and destination use XLR is the only compatibility step required.

The Belden XLR Male-to-Female Cable at 15 metres is a workhorse lead for live sound, recording and installed audio: standard 3-pin balanced connectors, a length that covers stage and hall layouts, and the noise rejection that balanced wiring provides over distance. It belongs in any PA or studio cable kit that regularly works beyond the reach of short patch leads.
