The River Cable Difference
Audio Cable Specific Tests
Bandwidth Uniformity Test
To ensure uniformity, we test our audio cables at video frequencies by passing a multi-burst video signal through the cable, with a maximum frequency of 4.5MHz. These frequencies exceed the defined analog audio bandwidth by a factor of 200! This ensures that your cable's frequency response performance is uniform far beyond the audible range! Up to 1dB rolloff at the highest burst frequency is permitted. In the graph for your cable look for the top of the bursts to be very nearly straight across.
In this demanding test a multi-burst signal is generated on a single video horizontal line. For relative differential loss, a variation of up to only 1dB is allowed for your cable. Differential loss is length dependent.
