Wireless microphone transceiver

A “wireless microphone transceiver” refers to a microphone system that uses a transmitter‑receiver pair to send audio wirelessly (no cable) from the mic to a receiver which outputs the sound to a recording or amplification device

Specifications

• <p>When evaluating a wireless microphone set (transmitter + receiver), these are the main specifications you should look at:</p><p><br></p><p> • <strong>Frequency / Carrier Frequency / Frequency Range</strong> — the radio frequency band on which the mic transmits (e.g. UHF 500–700 MHz, 514–596 MHz, etc.). This determines where in the radio spectrum the system operates.</p><p> • <strong>Modulation / Transmission Method</strong> — typically analog FM (for many traditional wireless mics), though some modern wireless mics may use digital transmission. Modulation affects how audio is encoded over radio.</p><p> • <strong>Number of Channels / Channel Spacing / Channel Options</strong> — how many distinct frequency‑channels the system supports (useful when many wireless mics are used simultaneously).</p><p> • <strong>Transmission / Operating Range</strong> — how far the wireless signal will reliably travel (line‑of‑sight). For good quality: often 50 m up to 150 m+ depending on system and environment.</p><p> • <strong>Audio Frequency Response</strong> — the range of audio frequencies the system can carry without too much loss/distortion (e.g. ~40 Hz–18 kHz, or ~45 Hz–20 kHz, etc.)</p><p> • <strong>Signal‑to‑Noise Ratio (SNR) / Dynamic Range</strong> — indicates how clean the audio is (how much noise vs actual signal). Higher SNR (e.g. &gt; 100 dB) is better.</p><p> • <strong>Total Harmonic Distortion (THD)</strong> — amount of distortion introduced by system. Lower is better (e.g. ≤ 0.5%).</p><p> • <strong>Output &amp; Output Connectors</strong> — how the receiver outputs audio (balanced XLR, unbalanced ¼″ jack, 3.5 mm, etc.), and output level (mic‑level, line‑level, output voltage).</p><p> • <strong>Power / Battery / Power Supply</strong> — what powers the transmitter (e.g. AA batteries or built‑in rechargeable battery) and receiver (AC mains or DC supply); also gives an idea of battery life / continuous use time.</p><p> • <strong>Transmission Power (RF output power)</strong> — sometimes given (e.g. &lt; 10 mW) — influences range and signal strength.</p><p> • <strong>Receiver Sensitivity</strong> — how good the receiver is at picking up weak signals (lower dBm is better sensitivity).</p><p> • <strong>Latency / Delay</strong> — time delay between speaking into mic and audio output (especially important if used for video or live monitoring).</p><p> • <strong>Operating Conditions</strong> — e.g. working temperature range, which may matter for outdoor or tour use.</p><p><br></p>
