Tube-Tech PM1A Microphone Preamp Module

The Tube-Tech PM 1A Microphone Preamp Module, a true high end mic pre and DI amplifier featuring extremely controlled and transparent sound. The PM 1A is based on Tube-Tech's famous MP 1A.

Tube-Tech PM 1A Microphone Preamp Module Details

The PM 1A is an exceptionally smooth sounding microphone preamplifier and direct instrument input amplifier (for bass, guitar, keyboard, etc.). The TUBE-TECH PM 1A is a combined Microphone Preamplifier and Direct Instrument amplifier. The input provides a switchable +48 V phantom power, a select-able mic impedance of 600/1200/2400 Ohm, a phase reverse switch, a low-cut filter (20 Hz/40 Hz/off), as well as a switchable -20 dB pad. Gain is adjustable from +10 dB to +70 dB.

The Direct Instrument Input is unbalanced with a gain ranging from + 10 dB to + 60 dB. The amplifier is all tube. Input transformer is enclosed in a MU-metal can. Input and output transformers come with a static screen between the primary and secondary wirings. The input and output are balanced as well as fully floating.

The TUBE-TECH modular Mic pre/DI is based on Tube-Tech's classic MP 1A, but with some important new features. The tube amplifier is upgraded to even higher headroom than the earlier TUBE-TECH mic preamps.(Overload is now indicated with a red LED.)

By adding this feature, John Petersen also raised the audio quality of the amplifier to a level nobody would have thought was possible. The first listening tests of the PM 1A immediately showed improved transparency and fidelity. Recordings done by Tube-Tech and their users have also proven the quality of the PM 1A to be true state of the art.

The impedance switch perfectly matches the input to all different types of microphones, including the increasing amount of popular ribbon mics. The high quality power supply of the TUBE-TECH RM series racks makes state of the art sound quality possible from a tube based modular system.
