Introducing the E3 ER-3000 Karaoke Microphone

The E3 ER-3000 is a wireless microphone system using the UHF 610–920MHz band, equipped with PLL (Phase Locked Loop) technology to precisely lock the frequency, reduce frequency drift, and ensure continuous connection.

The Micro E3 ER-3000 receiver boasts a signal-to-noise ratio of up to 105dB, low harmonic distortion below 0,7%, a frequency response of 45Hz – 18kHz, and reproduces vocals naturally, clearly, and with rich detail.

Technical parameters of the product to consider:

• UHF technology ensures stable signal transmission: The E3 ER-3000 operates on the UHF band of 610–920MHz, which helps reduce interference and signal loss. This is especially important in stages, auditoriums, or karaoke rooms where many wireless devices are operating simultaneously.
• Phase-locked PLL technology increases stability: The PLL (Phase Locked Loop) system precisely locks the frequency, minimizing frequency drift during use. This ensures the microphone maintains a stable connection, reducing the risk of signal loss or audio interruption.
• Operating range up to 300 meters: With a maximum transmission and reception range of approximately 300m, the E3 ER-3000 is well-suited for large spaces such as outdoor stages, large auditoriums, conference centers, and professional event venues.
• High signal-to-noise ratio and low distortion: A signal-to-noise ratio above 105dB combined with harmonic distortion below 0,7% results in clean, clear output sound, minimizing static and maintaining the fidelity of speech and vocals.
• Wide frequency response: The 45Hz – 18kHz frequency range allows the microphone to fully reproduce the sound spectrum from low to high frequencies, resulting in a rich, bright, and clear vocal sound, suitable for many musical genres.
• Long battery life: Using 2 AA batteries, it provides approximately 12 hours of continuous operation, allowing users to confidently use it during extended programs without needing to change batteries frequently.
