Revision 1.11Prism Sound dScope Series III

Method

The test is firstly performed with the Sub ON and all the pother speakers set to "small". The other

parts of the test have the Sub turned OFF, the left and right speakers set to "large", and all

combinations of "large"/"small" for the other speakers.

For each test, play track 61 and when the track has started playing, immediately click the

[OK]

button

to start the test.

The dScope measures the amplitude of each output channel against track time (and hence against

level), using a 400Hz band-pass filter to reduce the effects of noise.

Specification

The following results should be expected:

No compression

Output decreases linearly

Line mode (variable)

Output is flat for variable line mode compression, then decreases

linearly.

Full Line Mode

Output is flat at -11dBFS for 11 seconds, then decreases linearly.

RF Mode

Output is flat at -22dBFS for 22 seconds, then decreases linearly.
