bhi DESKTOP DSP 10 Watt Noise Cancelling Base Station Speaker

The bhi DESKTOP 10 Watt DSP noise-canceling base station speaker removes noise and interference to leave clear speech. It works on all types of radio, transceivers, receivers, and SDR radios, giving a new listening experience. The intuitive rotary controls make it very easy to use and set up to your own operating conditions.

The DESKTOP speaker comprises a 4" bass driver and a 1" tweeter unit with an amplified bhi DSP noise canceling unit capable of producing up to 10 Watts audio (peak). There are rotary controls on the side of the speaker for volume and filter level control.

The DESKTOP accepts either a standard speaker level audio signal from an extension speaker socket (4 or 8 Ohm) or a line level input signal can be connected via the separate "Line Level" socket on the rear of the speaker (useful for SDR radio and connection to Elecraft and Flexradio products). There is a 3.5mm headphone socket below the main controls that can accept either 3.5mm mono or 3.5mm stereo headphones.

The speaker is supplied with a quality 1.2 meter audio cable with a molded 3.5mm jack plug on one end and 4mm banana plugs on the other, as well as a 2.1mm fused DC power lead and user manual.
