High Sensitivity Reception and Squelch Circuit
The SDR-6220 employs dual-tuner automatic signal selection reception technology, offering superior performance and reliability. Its exclusive audio code and noise detection squelch circuit effectively prevent noise interference and improve reception distance. Users can adjust the reception sensitivity according to the environment to enhance reception distance or reduce noise interference, making it perform excellently in outdoor events, artistic performances, weddings, or sports competitions.
-
Multiple Audio Output Options
The SDR-6220 provides single-channel balanced (XLR) and unbalanced (Ø6.3mm) audio outputs, as well as mixed audio balanced (XLR) and unbalanced (Ø6.3mm) outputs, accommodating different audio equipment and application scenarios. Whether in theaters or large presentations, it delivers clear and powerful audio output. In educational and training settings, teachers can quickly connect playback devices for course audio, enhancing teaching efficiency and interaction. In corporate training and presentations, it provides stable audio output, ensuring every participant can clearly hear the instructions.
-
Flexible Volume Control Design
The SDR-6220 is equipped with a convenient volume gain control circuit, allowing precise adjustments for devices connected to MIC or LINE, providing MIC-LINE two-stage selection. This enables operators to adjust the volume to meet different audio needs in various events such as lectures and presentations, ensuring the best sound quality. Its intuitive control interface makes operation simple, even for non-professionals, meeting the needs of quick deployment. In sports events, it provides clear audio transmission, ensuring the quality of commentary and live reporting.
