A must for all professional Surround Studios * ITU-775 Surround Standard * Surround Scope , to control the power of the signal in the surround mix (see demo avis) * 6 Level Meters with 6 RMS Level Meters with different scales * DIN 45406, Nordic N9, BBC PPM, EBU PPM, digital PPM * K-System K-20, K-14, K-12 by Bob Katz * Reverence Level: 0dBFs, -18 dBFs (european broadcast), -20 dBFs (american broadcast) * All the 10 possible Correlations displayings (display as Bars or Lines with Max hold) * Compatible with all MME Windows driver ( see soundcards recommends below) The commonly applied DIN45406 with a head room of 6 dB referred to digital 0, Nordic N9, BBC PPM, EBU PPM and the K-System (K-20, K-14, K-12) by Bob Katz are easily and individually recallable by using the Windows-function keys F1 to F 8. PAS-Surround Meter can be configured in a number of different ways, to accurately model the ballistics, responses and graphics of a wide range of standard peak programme meters. These meters currently include the following: IEC 268-10 Type I - Nordic N9 IEC 268-10 Type IIa - BBC PPM IEC268-10 Type IIb - EBU PPM DIN 45406 K-System by Bob Katz K-20 K14 K12 Provides information about mutual phase-frequency relations between the signal of the left and right channel and allows us to spot any possible irregularities. These 'irregularities' may not have any significance in the case of stereo playback, but it should be remembered that the material we record can also be played as a mono signal (for example, on TV or on one of the radio stations which are broadcast or received in mono), and is worth sounding at least similar to what we imagined. However, you have to learn to read the indications of the correlation meter.
