Elysia MusEQ

The basic idea behind this analog EQ is the combination of premium sound shaping capabilities with optimally matched parameters which enables the user to find the desired results fast and precisely. The provided bands with their ample control ranges as well as some elysia-specific special features make sure that the museq can be used flexibly in any recording and mixing situation, and the stepped controllers are especially dedicated to mastering applications.

Each of the two channels offers three parametric bands with a switchable Q. The additional outer bands are low/high shelf designs which can be separately switched into a low/high cut mode with an extra resonance peak as a special finesse. Each gain controller of the two times five bands can be altered from boost to cut mode which results in a notably well resolution of the control ranges and twice the number of available settings. Both channels have a switchable option for a stronger coloration of the signal to complete the musical master plan.

The circuit design of the museq is completely based on discrete analog technology. The entire signal processing is realized with single transistors in permanent class A mode, and even the power supply is composed of fully discrete circuits. An oversized transformer, selected capsuled conductive plastic potentiometers as well as special current feedback amplifiers are part of the technical refinement. The combination of these elements aims at maximum signal quality and guarantees clean and powerful sound characteristics even when extreme settings are used.

100% DISCRETE CLASS-A:

As a true elysia specialty, the museq is completely based on discrete circuitry and does not use any integrated circuits at all.

ACTIVE BANDPASSES WITH FETS:

The filter stages are completely active and benefit from a puristic design approach without coupling capacitors - the basis for a truly musical EQ.

RESONANCE HIGH & LOW PASS FILTERS:

The outer shelving filters can be switched into high and low pass filters which feature an additional resonance peak as a very useful specialty.

PARALLEL FILTER DESIGN:

A special circuit trick makes it possible to leave the high and middle frequencies completely untouched when using the high and low pass filters.

WARM MODE:

The museq offers a second, switchable sound flavor by altering its frequency spectrum, harmonics and transient response.

PURE TRANSPARENCY PATH:

The puristic design of the filter stages with current feedback amplifier stages and without any coupling capacitors results in an outstanding sound quality.

BOOST/CUT MODE:

The boost/cut switch generates twice the number of values to be set with the 23 step potentiometers than the usual -/0/+ arrangement would offer.

SWITCHABLE FILTER QUALITY:

The filter quality can be switched from a wide to a narrow Q factor which remains independent from the setting of the gain controller.

STEPPED & MATCHED POTENTIOMETERS:

All potentiometers on the museq have 23 steps and are matched to build stereo pairs by a software routine that has been written just for this purpose.
