RM2/PM1A/CM1A Award 2012


PM1A Modular Microphone Preamp and DI

PM1A Description

The PM 1A is a combined mic preamp/DI, based on a classic TUBE-TECH design,

but featuring even higher fidelity and a few new features: An impedance switch to match the input perfectly to all types of microphones, an overload indicator and 2 dB gain steps.

 

Serious listening tests of the PM 1A have revealed a sound quality second to none, placing it among a handful of the worlds very best designs.


The PM 1A DI continues the TUBE-TECH tradition of extremely good sounding DI's, delivering world class sound for bass and guitar DI recordings. You simply won’t find a better DI than this!

 

Note: Due to the high quality of the TUBE-TECH RM Series power supply and the pristine audio circuits, the Modular Series products deliver exactly the same uncompromised sound quality as our 19” units.
 

 

 

 

 

 

 



Selected User statements PM1A

Markus Born, engineer for top German acts like Xavier Naidoo, Söhne Mannheims, Laith al Deen:


"The TUBE-TECH PM1A takes the philosophy of the TUBE-TECH preamps one step further in plasticity, openness and presence. The impedance switch lets you tailor the PM perfectly to every type of microphone, and both dynamic and ribbons sound sensationally well. Sources recorded with the PM 1A work very well in the mix and really shine due to a very rich harmonic spectrum."

 

John Garrison, singer/songwriter, touring bass player with James Blunt, session musician for One Direction, Christina Agullera, Robbie Williams.

 

John has for some time worked on his own project, Satellites under the artist name Johnny Vic and has released two albums by now:


"It just sounds better. My tracks sounds more like a record than with all the other preamps I have used. If you have a musical idea and good instruments, the recording sounds fantastic straight away, and then you can focus on being creative."

 

Gabriel Roth Producer, engineer, bass player, band leader, songwriter. Co owner Daptone Studios, Daptone Records.
Sharon Jones and the Dap Kings,Amie Winehouse, Antibalas, Michael Bublé, Charles Bradley, Naomi Shelton & the Gospel Queens, Menahan Street Band, Neal Sugarman, The James Hunter Six:


"I was blown away by how powerful and quiet the PM1A preamps were.
This preamp seems to have a lot of headroom, a lot of gain. They just sound great, man."

 

Sean Genockey, Producer, Mixer, guitar player, owner of Black Dog Studios.
IKO, Baddies, Tom McRae, Reuben, Manic Street Preachers, Suede,Tom Mc Ray:


"The TUBE-TECH's were awesome, I used them for drum recording at Rockfield. Great transients, tons of headroom, I love the transformer thing. They probably outperform the classic NEVE's , they have more headroom. tons of clean headroom, particularly for the snare. Really quiet, Yeah Impressed. I didn't once doubt it was the right mic amp!"

 
 
 
 
 
MP2A: ( Exactly same sound as PM1A )
 
Garry Boyle, Castlesound UK:

 

"I absolutely love the TUBE-TECH MP 2A! What a stunning mic amp. Used it on a record for vocal and double bass and then did all my overdubs on it and couldn't have
asked for any more from it.
As big and beautiful as any of the N**** mic amps (but with less noise) in the studio."

 

Wolfgang Stach, Producer and owner of Maarweg Studio 2, Cologne, Germany:


“I used the new Tube-Tech MP 2A in my current production of the German band Jupiter Jones and I am delighted: This new preamp has a charming but also very classy character which works excellent on various instruments I used it with. Really great (or “really cool”)!”
