Remember the Essentials
The proper system components are required. Make sure to get the proper system components for your needs.
Based on the MP 1A tube microphone preamp from Tube Tech, the PM 1A is a modular version that fits into their RM8 desktop power supply. The preamp also features a DI input and features extremely controlled and transparent sound.
The amplifier consists of a microphone input transformer with a step-up of +10dB, a dual tube preamplifier with 10dB/step coarse gain over a 20dB to 60dB range, augmented by a fine 2dB stepped attenuation of +/- 10dB, providing a total gain range of +10db to 70dB.
The output amplifier features 2 dual tubes in a push-pull configuration and an output transformer. The microphone input is provided with a switchable -20dB pad, selectable input impedance, switchable phase reverse and switchable +48V phantom power.
A Hi-Z direct inject input is unbalanced and placed in the circuit directly after the input transformer. The gain range for the DI input is 0dB to +60dB, with the microphone input disabled when in use. A high pass filter for the microphone and the DI input is switchable between off, 20Hz and 40Hz.
- All tube-based push-pull microphone preamplifier in a modular format
- Microphone gain available in 2dB (fine) and 10dB (coarse) steps
- 600/1200/2400Ω selectable microphone impedance
- Includes +48V phantom power, phase reversal and 20dB pad
- High impedance direct input
- Low-cut filter switchable as Off, 20Hz or 40Hz
- Utilizing the pad allows the unit to function as a unity gain line amplifier
- Overloading the input stage is not possible, while a red LED shows when output clipping is approaching
