It is also suitable for audio conferencing, computer, and desktop display equipment with a 3.5mm mic input.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Why is the 5-metre cable length important for calibration?\u003c\/h4\u003e\n\u003cp\u003eA: A longer cable allows you to position the microphone precisely at your primary listening seat — the sweet spot — while keeping your AV receiver in its cabinet. Accurate placement is key to getting the best room correction results from your receiver's auto-calibration program.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does omnidirectional mean for a calibration microphone?\u003c\/h4\u003e\n\u003cp\u003eA: Omnidirectional means the microphone picks up sound equally from all directions (360°). This is ideal for room calibration as it captures reflections, reverberations, and acoustics from every angle simultaneously, giving your receiver a complete picture of your listening environment to optimise audio output.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this microphone wireless or wired?\u003c\/h4\u003e\n\u003cp\u003eA: This microphone uses a 5-metre wired connection via a 2.5mm 2-core shielded enamelled cable with a straight 3.5mm plug.
