Mercury EQ-P1 Mono Tube Equalizer #0315 (Used)

The Mercury EQ -P1 Program Equalizer was designed to recreate every magical nuance of the original Pultec equalizers in a modern production. Mercury has tried to keep all elements in line with the original designer's ideas with only minor improvements. Adding a couple of extra frequencies for more flexibility, and using DC on the heaters (of the tubes) rather than AC for better performance as well as a new very quiet and stable power supply.

The Mercury EQ -P1 Program equalizer has transformer balanced input and output, with a fully balanced (push-pull) gain make up amplifier. Our new Mercury production utilizes only the highest quality passive components, while remaining true to the original production.

Interstage Transformer In/Out Switch
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 EQ -P1 Program Equalizer it is possible to do so with I.S.T. (Interstage Input Transformer) in/out switch, below the EQ in/out switch on the front panel. This takes the middle (interstage) transformer out of the circuit. Down, in the "in" position, it is more "vintage" like the original Pultec. Up, in the "out" position, it is a little more "open" and "airy" on the top. Either way, the input and output transformers are always in the circuit.

Mercury Recording Equipment Co. has gone to great lengths to recreate the pride and passion of the past, both sonically and aesthetically, while offering the reliability of a present day production. The choices made in looks, layout, functionality, features and build quality all answer back to one question: How would "they" have done it today?

Mercury Recording Equipment Co. products are hand wired and/or assembled using silver solder and no-compromise parts. All Mercury products are transformer balanced, inputs and outputs and there are no I.C.s (chips) in the signal path. The chassis and front panels have a very distinctive "vintage" look with custom powder coating finish. They look as good as they sound!
