TUBE-TECH PM 1A Mic Preamp

What engineers think:

The TUBE-TECH modular Micpre/ DI is based on our classic MP1A but features improved fidelity and new features.

The PM1A tube amplifier is upgraded to even higher headroom than the earlier TUBE-TECH micpre''s.  

By adding this feature, John Petersen also raised the audio quality of the amplifier to a new level .

The first listening tests of the PM1A immediately showed improved transparency and fidelity.

Many recordings has proven the quality of the PM1A to be true state of the art.

The micpre also features an impedance switch that perfectly match the input to all different types of microphones, including the increasing amount of popular ribbon mic''s.

Overload is now indicated with a red LED.

The high quality power supply of the TUBE-TECH RM series racks and no compromise quality of the audio circuits makes State of the Art sound quality possible from a tube based modular system.

PM1A DI delivers absolute top quality for Bass and Guitar DI recording.

It doesen''t get any better!

Technical Description

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 are 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.
