This test shows the juicedLink frequency response 13dB better than Beachtek DXA-2S from 20Hz-20KHz.
The 15dB range tested for the Beachtek DXA-2S does not even meet it’s own specifications that accompanied the unit, of +/-3dB for this bandwidth.

Did you realize that in terms of frequency response, there’s about a 13dB difference between this brand new Beachtek DXA-2S Dual XLR Audio Adapter, and the juicedLink CX family of Camcorder Adapter/Preamps? Let me show you these tests …
We’re going to use the HP8903A Audio Analyzer. The first thing that it does is it has a generator that provides a signal to your device under test. Then, it has a receiver that will analyze the output of the device under test. Today, we’re going to measure frequency response.
FREQEUNCY RESPONSE MEASUREMENT OF THE BEACHTEK DXA-2S DUAL XLR AUDIO ADAPTER: The measurement shows a 15dB range from 20Hz to 20KHz (both pots turned up all of the way, mic position, mono position). Looking at the documentation that accompanied the Beachtek DXA-2S Dual XLR Audio Adapter, it specifies it’s frequency response as +/-3dB from 20Hz-20KHz. So, this is NOT EVEN CLOSE to meeting Beachtek’s own specifications.
FREQEUNCY RESPONSE MEASUREMENT OF A JUICEDLINK CX FAMILY CAMCORDER ADAPTER/PREAMPS: The measurement shows a 1.94dB range from 20Hz to 20KHz.
So, the Beachtek DXA-2S tested a 15dB range over 20Hz-20KHz, when their own specification is only +/-3dB. This is 13dB worse than what was measured for the juicedLink frequency response.
