Mic Pre EQ

Mic Pre/EQ


The Mic Pre/EQ is a single channel high end, all discrete Class A transformer balanced (input and output) unit that combines a great mic pre and world class EQ in one single rack unit. Separate mic and line inputs can be selected from the front panel “line” switch without changing wires in back. Both inputs are combo XLR/ 1/4 in TRS. High gain of 70dB handles all types of mics from ribbons to dynamics and condensers. Switched phantom enables secure ribbon mic use and 20dB pad switch prevents overload on high output condensers mics. Front panel Phase switch for inverting input phase and large overall mute button and bypass button help the work flow.

“Mr. Daking,
I have been a fan of your work for quite some time now. Just wanted to drop a line saying how much I love and appreciate what you’ve done for the audio world. I own a pair of 52270B Pre/EQ’s and use them quite often. They have become staples in my studio. The amazing sonic clarity in the pre and razor sharp precision EQ are unprecedented and unmatched. I’ve used your gear to record for such artists as Rod Stewart, Zac Brown, Ani Difranco, Better Than Ezra and Dr John just to name a few. I actually even used the 52270B to record tracks for the Grammy Nominated Steve Riley and The Mamou Playboys record last year. Please keep up the great work and wonderful contribution to the forward advancement of a higher standard in the art of recording. Please feel free to use my name in your list of professional users. I’d be honored to have my name associated with your products and fine work. ”

Geoff Daking’s famous Mic Pre EQ has Four (4) individual EQ bands and Five (5) Stepped frequencies per band with frequencies specially chosen for effective results. This is thought to be some of the best EQ available for tracking, mixing or mastering. Continuously variable EQ boost or cut of 15dB. 25Hz High Pass 6 db/octave filter for getting rid of low end rumble that ruins tracks and 12dB per octave Low Pass filter at 15kHz helps get rid of extreme top end edginess. Separate overall output level control makes up gain lost in extensive EQ cuts. All relay switching with gold bi-furcated contacts for long term life. Steel construction for strength and noise immunity. An outboard “in line” universal power supply remotes the power to keep the noise floor low.
