The SEZ5600A II valve microphone by SE Electronics is an absolute must have for any serious sound recordists/producers/engineers. This multi-pattern workhorse executes articulate recordings with ease and precision. As you'd expect from the heavyweights behind this awesome microphone, it is built like a tank and ready-for-action straight out the box.

Updated components

The updated model follows the same design pattern set out by its predecessor, equipped with a dual-diaphragm capsule - back-to-back cardioids -, which is a cosy 1.07" in diameter. A dual-triode ECC83 tube feeds into an output transformer to give a warmth and texture that embodies tube mics perfectly. The SEZ5600A II make look quite plain but it is anything but cold, breathing life into every recording.

The improved design to the power supply unit and internal circuitry has lowered the noise to 12dB A-weighted, while the maximum SPL handling level is an impressive 135dB. Along with the smooth frequency response from 20Hz ~ 20kHz, these details ensure that vocal recording is as smooth as you can get, capturing the subtlest nuances in a singer's voice.

Polar opposites

The ability to switch between different polar patterns makes this already awesome microphone truly brilliant. The cardioid response offers fantastic clarity in the higher frequency range. In omni mode, you have an excellent mic for capturing room ambience and close miking acoustic instruments. With the figure-of-eight mode, the low-end is slightly exaggerated based on proximity to the sound source, ensuring the full character is retained. The polar pattern selection switch is on the power supply unit, reducing the number of component parts on the mic itself. The mic also comes with a specially designed shock-mount prevent external vibrations from affecting the signal feed, and preserves the longevity of the valve.

Though it is unlikely that you'll ever need to, the ECC83 valve inside is relatively easy to get to and change, so if you're an engineer who links to tinker with your equipment, this is another fantastic design feature.

Attention-to-detail is key with SE, and the SEZ5600A comes in a wooden presentation case within a full aluminium flight case. The new power supply unit is finished in stylish brushed aluminium.

If you're a producer, artist or engineer who is looking for a solid, reliable, versatile, accurate and articulate multi-pattern microphone, the SE Electronics SEZ5600A II valve is an absolute must have. It is built to last, captures the natural timbre of an instrument perfectly and looks pretty cool too.
