Product introduction

MA-1 is a professional microphone preamplifier that operates on 48V phantom power, but does not pass phantom power to the microphone. This makes it ideal for ribbon and dynamic microphones alike. It made by cold-rolled plate, firm and durable. The four foam pads which raise the resist falling capability of microphone in a way. Its black looking makes it classic and graceful. All in all, MA-1 is a better choice for you to use.

Specification: * Gain:30dB* Frequency response:20Hz-20kHz±1dB* Input impedance:150Ω* Noise:

<3mv

* Size:100mmX50mmX38mm

MA-3:

MA-3 is a professional microphone preamplifier that operates on 48V phantom power, but does not pass phantom power to the microphone. This makes it ideal for ribbon and dynamic microphones alike. It made by aluminum, firm and durable. Its impedance adjustable and HPF switch enhance performance ability. Also OUTPUT LEVEL switch helps you to adjust the signal and reduce the noise. It made by alum, firm and durable.

1、Dynamic and passive ribbon mic preamp

2、Receive balanced line level signal from the recording system or mixer

3、High pass filter eliminates excessive resonance

4、Play pre-recorded tracks through amps

5、Offers +25dB gain without any coloration

6、On board level control for fine tuning amp level

7、Adopts JEFT FET amp circuit to amplify signal with low noise and quiet output

12DB/25DB two gains can be adjusted (MAX+25DB, MORE+12DB)

Free adjustment of impedance
Applicable to more microphones

Compared with MA-1, MA-3 adds the function of changing the input impedance (150Q to 15KQ), adjusting the impedance to match the impedance of the microphone, so as to find the ideal working state of different microphones. At the same time, you can creatively load the output voltage by adjusting the impedance, so that each microphone can get a wide range of sound quality changes. Usually the input impedance suitable for ordinary microphones is 1.5K or higher.

Adjustable variable high pass filter
Shaping more sound quality

When the MA-3 impedance and high-pass filter are combined and changed, the work can get more sound quality shaping and control. The cut-off frequency during operation is affected by the impedance setting. When the user rotates the impedance adjustment knob, the frequency range that can be swept is from less than 20HZ to about 200HZ. This is very important for the timbre properties and near-field effects of ribbon microphones or dynamic microphones.
