Frequently Asked Questions

Q: What AV receivers is this calibration microphone compatible with?

A: This replacement calibration microphone is designed to be compatible with Pioneer AV receivers that use a standard 3.5mm straight-plug omnidirectional condenser mic for their auto-calibration systems. It is also suitable for audio conferencing, computer, and desktop display equipment with a 3.5mm mic input.

Q: Why is the 5-metre cable length important for calibration?

A: 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.

Q: What does omnidirectional mean for a calibration microphone?

A: 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.

Q: Is this microphone wireless or wired?

A: This microphone uses a 5-metre wired connection via a 2.5mm 2-core shielded enamelled cable with a straight 3.5mm plug. It does not require batteries or wireless pairing, making setup simple and reliable.
