Frequently asked questions
What's the practical difference between Band B and Band D?
Band B operates at 537.9 MHz and Band D at 540.4 MHz. This separation allows both systems to coexist in the same venue without interference. Choose based on your local frequency coordination, venue requirements, or if you already own compatible equipment on one band.
Does one frequency sound better than the other?
No. Both deliver identical audio specs: 105 dB(A) signal-to-noise ratio, 0.8% total harmonic distortion, and 30–20 kHz bandwidth. The only difference is the radio frequency channel, not the sound quality.
Is Band D really better for acoustic instruments?
Band D is marketed for acoustic and classical use and explicitly noted as not ideal for high-output electric instruments requiring sustained RF range. However, the audio circuitry is identical to Band B; the recommendation reflects typical RF range and interference patterns in those frequency bands rather than tone shaping.
Will either system work for live gigging?
Yes. Both include 30-hour battery life, reliable 10 mW RF output, ultra-compact design, and professional-grade SNR. Either suits live performance; frequency choice depends on your venue's RF environment and any existing wireless systems.
