Availability:  


Warmth and accuracy for your condenser mics!

With the Electro-Harmonix 12AY7 Tube Microphone Preamp, Electro-Harmonix offers an affordable tube micrphone preamp that won't disappoint. Equipped with a 12AY7 EH tube and a 12AU7 EH driver, it gives microphones the widest dynamic range with the warmest possible tone and accuracy. The 12AY7 Mic Pre uses an actual 200V supply instead of the "faked out" 12 or 48 volts you'd get with common models and delivers 50dB of gain into a high impedance load or 40dB gain into 600 ohms.

The 12AY7 Mic Preamp's special FET current-balancing circuit allows the tubes to amplify the microphone signal to line level while eliminating noise and protecting against hum and hostile electrical environments. It has an extra TRS output for separate line control, which can be used as a splitter or an aux send for monitoring. Input connections are balanced in and out (XLR) with a 1/4" TRS balanced buffer out. The Electro-Harmonix mic pre unit also boasts a phase reverse switch and a +4dBm indicator light for setting optimal mic level. The 48V phantom power is soft starting and pop-free.

  • Equipped with a 12AY7 EH tube and a 12AU7 EH driver
    Wide dynamic range, warm tone, and superb accuracy

  • I love it!

    As reviewed by Vee on 5/29/2007

    I did quite a bit of research on the internet in search of a pre that offered the best perfomance to value. You can't go wrong with this pre. It sounds very warm and it's very quiet. Even my cheap mics sound expensive!

  • Its great and horrible at the same time...Listen closely...

    As reviewed by Jim on 5/23/2011

    First, it is a strange size, about the same size as all EH other pedals etc,...to save money i am sure...Its HORRIBE if your output goes to any unbalanced source, including compressers (FMR RNC RNLA etc), audio interfaces(old m-audio cards with RCA type connectors), reverbs units etc..., Now it's great if used with balanced sources like DBX 160a compressor, PBC 6-a compressor, anything balanced thaat has balanced inputs... the things is going into unbalanced, youll hear hum...HORRIBLE Going to a balanced source GREAT CLEAN SOUND.... I have one, but cant use it with my RNC, RNLA or my older DBX 163x compressors or my unbalanced Alesis QuadraVerb...

  • Does the job GREAT

    As reviewed by screamodude on 7/16/2007

    I was told that this little box would do the trick and so far, I havent had any problems with it. It may not be the best pre-amp but it curtainly went beyond my expectations. Its a good overall product, Pick it up
