Know before you buy
ShowLink allows you to make real-time adjustments to your transmitter settings, such as frequency changes or gain levels, directly from the receiver. This eliminates the need to physically handle the microphone during a live performance or broadcast.
High Density mode optimizes the transmission signal to allow for a significantly higher number of active channels within the same frequency space. This is ideal for large-scale productions where spectrum congestion is a concern.
Yes, the transmitter features AES 256-bit encryption. This ensures that your audio signal remains secure and protected from unauthorized interception, making it suitable for government, corporate, or sensitive broadcast environments.
Using the SB900A rechargeable battery, you can expect up to 9 hours of continuous operation. The system also provides precise remaining runtime data, so you can monitor battery health throughout your event.
The ADX2/B58 features a wide tuning range of up to 184 MHz, which provides significant flexibility. However, you must ensure the specific frequency band you purchase aligns with the local wireless regulations of the region where you intend to operate.
Frequency Diversity allows the transmitter to send audio simultaneously on two independent frequencies. If one frequency experiences interference, the receiver automatically switches to the clean signal, ensuring your audio never drops out.
