Why do Escort/Bell/Cobra detectors require a different cable than the Valentine One?
The Valentine One audio break-out box has a headphone jack that is a stereo output and uses a 3.5mm stereo jack. Other detectors are monaural output and thus require a mono cable. Most others (notably Escort, Bell, and Cobra) also have ungrounded outputs and require isolation. Other products sell isolation cables at ridiculous prices, while the Mix-It2 has the isolation built into two mono inputs.
