MASELEC MDS-2
High Frequency Limiter
Page 2 of 4
DESCRIPTION
The MDS-2 is a dual mono, linkable, high frequency limiter. It is housed in a 1U
19" rack mount alloy case. It is primarily intended for use as a de-esser, reducing
unattractive high frequencies, with minimum coloration and loss of clarity.
Automatic time constants and optimisation techniques for the gain reduction
minimises the number of controls. The advantage is not only simple operation but
also increased performance for highly dynamic and inconsistent materials without
the need for continuous readjustments.
With wide input range, up to +29dBu input and low noise, the MDS-2 can be used
in many different applications.
The side chain can be switched to M-S, which can be used to “zoom” in on high
frequencies in the centre of the stereo image. With this function switched in the
threshold is 6dB lower for the centre image compared to extreme left and right.
The M-S function does not affect the actual audio path.

Output frequency response when
the HF limiter is adjusted for max.
high frequency reduction.
4dB reduction: 5msec attack.
10 dB reduction: 1 msec attack
This shows how the attack time
becomes shorter when the high
frequency reduction is increased.
