Chapter 6 The Extended Audio Matrix. PRELIMINARY Release MSD Software Manual.

To monitor the exact phase relation between any two signals in the Jelly-Fish™

these signals can be routed to the separate ‘Phase Correlation Meter’ which is

destination #53 and #54.

When using a factory preset on a surround sound format using a separate Low

Frequency Energy "LFE" channel (format 5.1 and 7.1) the MSD600M will

include this LFE channel on the PPM-bargraph but since the LFE channel does

not contain any frequency information that can be directional determined it is

NOT included in the Jelly-Fish monitor.

7.3 The Peak Programme Meter (PPM).

The ‘Peak Programme Meter’ is designed for direct measurement of the quasi-

peak level of complex electrical signals ocuring in the transmission of music

and speech, without varying the sensitivity of the device, to achieve optimum

technical utilization of the transmission channel, or the recording medium.

For this purpose a full-wave rectifier is used, and the integration time is chosen

to obtain an amplitude as high as possible, without overloading the

transmission link for a period long enough to give rise to audible non-linear

distortion of the programme. The return time is relatively long in order to avoid

unnecessary viewer fatigue.

The ‘Peak Programme Meter’ is capable of showing up to 32 input channels

simultaneously. The number of visible channels are configured in the Audio

Matrix. When PPM-bars are enabled or disabled the Audio Vector Scope

window is automatically scaled to fill the remaining part of the screen. See

section 4 for information on how to route audio channels to the PPM bars.

(Destinations #65 to #96.) Please observe that if the Jelly-Fish™ is active the

maximum number of active PPM-bargraphs is 16.

Please refer to section 6.3.1 for information on how to change the appearance

of the PPM bargraphs.

The configuration of the ‘Peak Programme Meter’ is done from the [Meter]

menu.
