Z&H DESIGNS ME-250DX

The Unrivaled Circuitry Build

We have redesigned all the circuitry, and included 12 all-discrete opamps inside. Compared with the traditional IC opamps, the all-discrete opamps offer unrivaled bandwidth and dynamics. The circuitry is composed of precision transistors that are accurate to 1% throughout, with multiple layers.

Even without any noticeable colourisation, you can still immerse yourself in the beauty of analog.

M/S Encoder/Decoder Onboard

We acknowledge and agree that M/S processing is essential for many engineers' workflows. Therefore, we installed a premium full analog M/S encoder/decoder, which is all made with THAT chips, into ME-250DX.

In M/S mode, the channel on the left becomes the mid channel, while the channel on the right becomes the side channel. You can also bypass the entire channel in either M/S mode or Left/Right mode.

Precisely Matched to <1%

Each unit takes days to stereo-match by hand. We make sure every step and frequency point is accurate to less than 1% for mastering standards.

When tested with Audio Precision or other tools, the curves will precisely merge as one.

Independent linear power supply

Each channel receives its own 56V high-voltage linear power supply. Such timeless power solution has been proven to be the bedrock of a clear and punchy sound. It helps handle a higher dynamic range, offers more headroom, and reduces noise effectively.

Each band per channel marks a unique set of frequency points, collectively forming over 100 frequency points.

Both gain knobs and frequency knobs are custom-made with 21 steps.

The Q knobs at the top also have 12 steps between 0.6 and 4, with the iconic shelf option on the Low band and the High band.
