BHI DESKTOP MKII DSP - Noise Cancelling Base Station Speaker

Dramatically reduce noise and interference and hear more clearly!

The DESKTOP MKII speaker is the perfect solution for radio enthusiasts seeking crystal-clear audio in their base station. Its sophisticated DSP noise cancellation technology identifies the speech signals and allows you to remove the unwanted background noise and interference while preserving speech clarity, making it ideal for challenging listening environments. The easy-to-use controls allow real-time adjustment of both volume and filter levels to match your specific operating conditions.

Built for versatility, this speaker seamlessly integrates with virtually any radio setup through multiple connection options. The speaker-level inputs (4mm terminals) handle traditional 4 to 8 ohm radio outputs, while the 3.5mm line level input socket is perfect for modern SDR radios and low level audio signals. The convenient side-mounted headphone jack allows for private listening without sacrificing audio quality. With its robust construction and professional-grade components, the DESKTOP MKII delivers exceptional performance that can transform your radio listening experience from frustrating to enjoyable.
