MIDAS - The Legend
in Sound Quality

Ever since its formation in the 1970s, MIDAS has
had a long history of innovation and leadership
in the world of audio mixing consoles.
Employed by the most famous touring acts
and installations worldwide, legendary MIDAS
consoles such as the XL4 and Heritage H3000
quickly became industry standards.

MIDAS has earned their impeccable reputation

due to their no-compromise approach for
audio and build-quality and in particular for
their Award-winning Mic Preamps, which are
considered by industry experts as the industry’s
best sounding designs. Building on this legacy,
the XL8 and PRO Series of Live Mixing Systems

continue this great heritage of Award-winning audio quality.

KLARK TEKNIK is proud to incorporate MIDAS designed input and output transformers for the

ultimate in high-quality audio reproduction in both live and studio environments. Find out

Compressors/Limiters

76-K T

Classic FET-Style Compressor with
Class-A Line Level Amplier and
MIDAS Transformers

Sublimely Easy to Operate

The compression ratio is selected by pushing any, or all, of the Ratio buttons located to the left of
VU meter. Ratios available are: 4:1 for moderate compression; 8:1 for severe compression; 12:1 ratio for
mild limiting; and 20:1 for hard limiting. Using the “All-Button” mode can be especially eective when
applied to drums, bass, guitar, and room mics – or for more aggressive “in your face” vocals.

Attack & Release

76-KT’s Attack knob adjusts the amount of time it takes the compressor to respond to audio that
exceeds the threshold. The response time is slower at the fully counterclockwise position and faster
when turned clockwise. The Release knob adjusts how long the compressor remains engaged after the
incoming audio falls below the threshold. The response time is also slower at the fully counterclockwise
position and faster when adjusted clockwise.

Vintage Style VU Meter

In keeping with the design of the original processor, the 76-KT features an illuminated,
vintage-style VU meter for visual conrmation of gain reduction (GR) and output levels. A meter reading
of 0 corresponds to an output level of +4, +6 or +8 dBm, depending on which button is engaged.
