M-S....................... Switches the side chain inputs to M-S (sum and difference). 

LINK...................... Hard links the side chains after the time constants. 

ON........................ This control enables the high frequency limiter. 

FAST..................... This control makes the release time shorter.

HF THRESHOLD......Adjust this control to set the amount of high frequency limiting.

BYPASS..................Galvanic bypass of the unit. The meters show, with reduced intensity, the gain reduction that would occur if the unit was

not in bypass

Maselec MDS-2 De-Esser High Frequency Limiter

The MDS-2 is a High Frequency Limiter which is often used as a De-Esser. It can also replace Acceleration Limiters for vinyl disk cutting,

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.
