TUBE TECH - MP1A

This combined dual microphone preamplifier/DI amplifier contains two independent amplifiers for microphones or instruments.

The microphone inputs are balanced providing switch able 48 V phantom power and a switchable -20 dB pad. 
Gain is adjustable in 5 dB steps from +20 dB to +70 dB. 
The DI-inputs are unbalanced with a gain ranging from +10 dB to +60 dB. 
No pad provided.

The amplifiers are all tube (valve) based and the heaters are fed DC-voltage to avoid hum. 
All transformers (except the main transformer) are enclosed in mu-metal cans. 
Input and output transformers come with a static-screen between primary and secondary wirings.  Microphone inputs and outputs are balanced, and are fully floating.

Features :

  • Gain from +20 dB to +70 dB in 5 dB steps.
  • Pad in front of input transformer (-20 dB).
  • Tube (valve) push-pull output-amplifier.
  • CMRR >60 dB @10 kHz.
  • Microphone input impedance = 1200 ?
  • DI input impedance >1 M ?
  • Built-in 48V phantom-power.
  • Noise figure typical 5 dB @ 200 ?
  • Frequency-response 15 Hz to 60 kHz (-3 dB).
  • Jack-socket DI-inputs for various instruments.
