HEAR IT DESKTOP SPEAKER

Product Description

Dramatically reduce unwanted noise and interference!

The HEAR IT DESKTOP 10 watt DSP noise cancelling base station speaker will work with most radios, transceivers, receivers, and SDR radios, giving a new listening experience.  The new 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  DSP noise cancelling 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 speaker can be connected to a stereo line level audio input signal, or to a standard speaker level audio signal from an extension speaker socket. There is a 3.5mm headphone socket below the controls that can accept either a 3.5mm mono or stereo jack plug.

The speaker is supplied with a quality 4 foot  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.
