DK-Technologies MSD600C-III
Color Master Audio Meter for Surround Sound
(Desktop Version)

• Features Peak program Meter for audio level measurements.
• 7 scales selectable to conform with standard used.
• PPM peak-hold function shows maximum level in a recording.
• Vectorscope display supports aural impression at a glance.
• Phase correlation meter indicates proper phasing to allow for downmix.
• 2 analog audio and 2 AES-3 inputs are readily available for choice of input format.
• 2 analog audio and 2 AES-3 outputs connect via the internal matrix to inputs, internal audio generator, and sum and difference amplifiers.
• Choice of 1024 point FFT spectrum analyzer and 1/3-octave analyzer for display of frequency distribution of each channel over full audible range.
• AES-3 bit stream status display indicates characteristics of the digital audio signal.
• Bright, VGA color display with adjustable backlight allow adaptation to environmental light conditions.
• VGA output connects to external monitor for remote or larger display.

The Level Meter has direct selection of 7 PPM/VU scales. All the standard scales are available including Nordic, EBU, BBC, ABC, NBC, DIN, VU, Digital and others. Each scale can be configured individually concerning overload level and reference level. Furthermore the color and width of each PPM bar can be set by the user.

The DK-SCALE software program for Windows contains a large library of scales, which can easily be downloaded to the meter. Modification of existing scales or designing of new scales according to your own specifications are also possible with the software. For easy identification each channel can be named individually with up to 4 characters.

Stereo Sound
The oscilloscope shows the stereo image in the Lissajous-format, where a perfect stereo signal would be represented by a circular figure, or a ‘ball’, and mono would be a vertical line.

Phase Meter
The phase meter is of the “center-zero” type and immediately advises out-of-phase errors by pointing towards the [-1] area and changing to red color.

Signal Generator
Another strong point of the instruments is the built-in signal generator. It has a tone generator variable in frequency from 31 Hz to 20000 Hz, and the level in steps of 0,1 dB.

In addition it can generate the EBU test signal, pulse signals, and white and pink noise signals for use with the spectrum analyzers. Use the generator to turn the instruments into a powerful measurement tool for analysis of linearity and distortion.

Spectrum Analyzer
The spectrum analyzer section has both an FFT-analyzer and a 1/3 octave analyzer.

The FFT is primarily used for accurate measurements and exact identification of problem frequencies. To this end a cursor is available and level and frequency will be shown for each cursor position across the frequency range on the display.
