Phantom powered mic preamp with phantom passed on to the microphone.

3 input connector options available, standard, extended female and locking female XLR

  • Superb audio quality, ruler flat frequency response, low noise.
  • No batteries, no mains, no switches, knobs, presets or controls
  • Pocket size
  • Strong Neutrik alloy case, gold plated Neutrik XLR connectors
  • 20 dB of mic level gain
  • Operates from 12-48 V phantom power
  • The preamp behaves in DC terms as if it was
  • Input (female XLR) connector options:
  • Standard - accepts a cable mounted standard XLR
  • Extended - can be connected directly to a microphone or panel monted XLR
  • Locking - extended female XLR for direct connection to microphones and other panel XLR's, the ring can be tightened to ensure the unit is fastened securely to the microphone, it can then be locked in place with a hex head screw

Specification

Audio
Gain 20 dB fixed
Gain Accuracy ±0.5 dB
Frequency response 20 Hz - 20 kHz ± 0.25 dB, 150 ohm source
Equivalent input noise (EIN) -115 dBu at 20 dB gain, 150 ohm source, flat weighting, 20 Hz - 20 KHz
Output clipping level -10 dBu with 600 ohm load
Input clipping level -30 dBu at 20 dB gain 600 ohm load
Input - electronically balanced, 1K ohm input impedance
Polarity - input to output is non inverting, polarity is preserved
Output - electronically balanced 200 ohm output impedance

Power
Powered from 12 to 48 volt phantom power (DIN 45 596).
The amplifier is equipped with self sensing power circuitry and depending on the source microphone will adjust between the following worst case scenarios:
For a phantom powered mic requiring maximum current there will be a phantom voltage drop of 2.6 volts and no shunt current used; for a non phantom powered mic there will be a phantom voltage drop of 2.6 volts and a shunt current of less than 1.5 mA.

Physical
Strong Neutrik extruded aluminium case with laser engraved legend.
Internal circuitry encapsulated for robustness and maximum moisture resistance.
Connectors all Neutrik gold plated 3 pin XLR.
Pin 1 -ground
Pin 2 - signal + (hot)
Pin 3 - signal - (cold)

Operational Guidelines
The preamplifier is designed to boost low level mic signals before they go into the microphone input of a recorder or sound mixer. It is not designed for and should not be used to amplify a signal to line level. At levels above -10 dBu distortion will begin to occur. A typical situation may be an effects mic which would normally have 60 db of gain at the mixer. Instead the mixer gain could be reduced to 40 dB with 20 dB provided close to the microphone by the Mini MicBooster.

The preamplifier is best positioned as close to the microphone as possible, in this way the maximum signal to noise benefit will be achieved.

It is powered from 12 to 48 volt phantom power which is normally switchable on the microphone input of most professional recorders and mixers. It cannot be used with other forms of microphone power.
