MODES OF OPERATION
Principal of Operation
The Model V610 “COMPLIMITER” is the first compressor/limiter that allows for the professional the widest
range of separate and distinct mode of operation. The attainment of this flexibility is based upon being able to
easily and precisely set the input and output level controls. This is a result of interaction among the following
principals of operation:
1.
Accurate monitoring of peak vs. average input signal levels using visual “threshold” LED indication and
Vu meter, respectively.
2.
Constant threshold attack level for any compression slope setting.
The following modes of operation result from interaction of the above principles and are recommended for
actual use to demonstrate the simplicity of obtaining both maximum performance and maximum versatility with
the Model V610.
1.
Normal linear amplification.
2.
Peak limiting only (maximum level below fixed amplitude without affecting dynamic range).
3.
Compression and limiting simultaneously.
4.
Compression only.
5.
Limiting and compression with additional fixed amplitude protection, (maximum percent modulation).
Through variations of these separate and distinct modes of operation, innumerable audio signal combinations
are obtainable. For each mode of operation there follows an explanation of the interaction of the principals of
operation, control settings and typical applications.
Normal Linear Application
This mode of operation always occurs when both the average and peak level of the signal waveform are below
the threshold attack level of -40 dBu. Since neither the compression nor limiting functions of the Model V610
will be activated, the slope control and release time settings will have no effect on the output, and 20 dB of
normal linear amplification will be provided. In addition, whenever the slope control is set to the minimum
compression/limiting ratio of 1.1 to 1 (“100” slope control setting = fully clockwise), normal linear
amplification occurs for all input signal levels above the -40 dBu threshold attack level. This latter condition of
operation above the threshold attack level provides the maximum signal-to-noise ratio for the device.
