Mercury EQ-H1 Program Equalizer

Pultec Equalizers are some of the rarest and most sought after studio tools in the industry today. Engineers lucky enough to be able to work with them find their musicality and warm tonality extremely important to their studio's "sound." The simple beauty of these EQs is unsurpassed!

The original Pultec equalizers were tools developed to deal with the limitations of recorded music. Limitations that most often manifest themselves in the highest and lowest frequencies of the program material. Pultecs were designed to bring back the life and musicality lost in the recording. Whether by accident or genius, nothing has been able to do it better. The interaction of the passive boosting and attenuating shelving eqs (not relying on negative feedback), as well as the transformers, tubes and other amplification circuitry all add to the incredibly musical character of the product. Working engineers try other types of equalizers, but always end up coming back to the Pultec as the equalizer of choice for those final touches.

Mercury EQ-H rear view Mercury Recording Equipment Co. is committed to recreating every magical nuance of the original in a modern production. The goal was that the Mercury EQ-H1 Program Equalizer would add that magic touch to music like the original, we achieved that goal. 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 we use 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-H1 has transformer balanced input and output, with a single ended gain make up amplifier. The EQ-H's passive EQ/gain make up amp topology provides a musically satisfying result unobtainable with active and parametric EQs, since it does not rely upon negative feedback (and all it's associated phase and dynamic distortions) to achieve equalization.

2, 3, 4, 5, 6, 8, 10, 12, 16 kHz boost, 0-16dB
10 kHz shelf attenuate, 0-16dB
Frequency response: 20 Hz- 20kHz
Noise: = -97 dB below OdBm
THD: = 0.15% at +10dBm @ 600 ohms

MERCURY RECORDING EQUIPMENT 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!
