Compressor pages.
About the Compressor
The Compressor section of the DBMAX is divided into five
bands. This means that you are able to compress five different
frequency areas separately.
Based on a number of requests from initial users of the DBMAX,
the automatic Make-Up gain has been removed, even though it
partly still exists when using the Less/More handle.
Normally you should use the overall gain labeled OUT on Page 2
for Make-Up, and by having full control over the individual band
levels there is now a very efficient way of adding post dynamics
Equalization to your signal.
Dynamic Equalization can also be achieved simultaneously by
using different Threshold and Ratio values in the different bands.
If you want to off-set the spectral balance (EQ) of low level
signals, use the Band Levels in page no. 2 of the Compressor
block.
If you want to off-set the spectral balance of high level signals,
use the Threshold and Ratio in page no. 2 of the Compressor
block.

Less/More - Compression
An overall compressor intensity parameter. By using this function
you can increase or decrease the intensity of compression while
keeping the relationship between the Threshold and Band level
parameters in accordance to the specified Ratio settings.
Threshold, Ratio and Band level parameters are found in page 2.
Flag indication
Different letters (flags) will occur on the In and Out line in the
Compressor.
D - Delay time. (1-400ms) A “D” indicates that a Delay time has
been added in the In block page 1 for the digital Inputs/
Outputs. The first 10ms. works as a look ahead-delay to
increase the precision of processing.
Note! Please refer to page 19 for additional info on delay thru
the unit.
E - An “E” on the In-line indicates that Emphasis is present on
the Input signal. The DBMAX automatically removes
Emphasis present from the Input signal.
F - Input Hi-Cut/Lo-Cut filters active.
These filters are described on page 20.
S - Sample Rate converters on.
Gain Reduction
Graphical indication of the actual gain reduction performed by
the Compressor.

Threshold
Use the ADJUST wheel to change the Thresholds of the five
bands.
The Thresholds refer to “Ref. Level” in the Ref. Level menu.
Ratio
Use these parameters to adjust the Ratios of the gain
reduction in the five Compressor bands.
Band Level
The five band levels are used to adjust the spectral balance of the
Compressor. Below the five bands, the level of the Mid band is
displayed.
Out Level
With this parameter you can adjust the overall Output of the
Compressor. This is the parameter you would use as make-up
gain.
