The Mini MicBooster provides 20dB of microphone level gain. It is powered by 48V phantom power which it will then pass on to the microphone. No batteries are required – just plug it in and you are ready to record. It is particularly suitable for use where a low output microphone is used with a recorder which has inadequate gain or a noisy built-in preamp.
The MicBooster has a strong Neutrik alloy case and panel-mount Neutrik XLR connectors which are suitable for mating with cable connectors.
Specifications:
Audio:
* Gain: 20dB fixed
* Gain accuracy: ± 0.5dB
* Frequency response: 20Hz – 20kHz ± 0.25dB, 150 ohm source
* Equivalent input noise (EIN): -115dBu at 20dB gain, 150 ohm source, flat weighting, 20Hz – 20kHz
* Output clipping level: -10dBu with 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 solely from 48V 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 2.6V and no shunt current used. For a non phantom powered mic there will be a phantom voltage drop of 2.6V and a shunt current of less than 1.5mA.
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)
Dimensions and weight:
* Dimensions: 78mm (l) x 26mm (w) x 31mm (h)
* Weight: 88g
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 -10dB distortion will begin to occur.
* 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 by 48V phantom power which is normally switchable on the microphone input of professional recorders and mixers. It cannot be used with other forms of microphone power.
