Mercury EQ-H1 Equalizer Pair – No Longer Available
The Mercury EQ-H1 Program Equalizer has transformer balanced input and output, with a single ended gain make up amplifier. The EQ-H1’s passive EQ/gain make up amp topology provides a musically satisfying result unobtainable with active and parametric EQ’s, since it does not rely upon negative feedback (and all it’s associated phase and dynamic distortions) to achieve equalization. The new Mercury production utilizes only the highest quality passive components, while remaining true to the original production.
The Mercury EQ-H1 has a different amplifier than the Mercury EQ-P1 thus it has a different tone. The EQ-H1 and EQ-P1 sound different on the same application. The EQ-H1 is more punchy and robust and the EQ-P1 is more open and silky.
The Mercury EQ-P1 also has transformer balanced input and output, with a fully balanced (push-pull) gain make up amplifier. The only modernization feature on the unit is a user switchable (in/out) interstage transformer. In the original Pultec EQP this transformer was always in the signal path, however, realizing that some of today’s engineers might want to remove it with the Mercury EQP1 Program Equalizer it is possible to do so with in/out switch on the Front Panel. This takes the middle (interstage) transformer out of the circuit Up, in the "in" position, it is more "vintage" like the original Pultec. Down, in the "out" position, it is a little more "open" and "airy." Either way, the input and output transformers are always in the circuit. The new Mercury production utilizes only the highest quality passive components, while remaining true to the original production.
