Wide range of application scenarios: compatible with all kinds of microphones, for mpa M6 is a multifunctional microphone amplifier, suitable for a variety of scenarios with strong compatibility, suitable for both condenser and dynamic microphones. 48V phantom power: using digital timing control, precise timing control, not only can not hear the impact noise, but also can reduce the impact on the microphone and the microphone amplifier, extending the service life of the equipment. Powerful EQ vocal adjustment: improve the dynamic details of the microphone, EQ vocal adjustment enhances the appeal of the singing voice. The three-band equalization can make up for some deficiencies of the microphone or vocal frequency. Full power and long-lasting battery life: if a 3500mAH 18650 lithium battery is used to connect a dynamic microphone, when the +48V phantom power is not turned on, the battery life is about 50 hours. When a condenser microphone is connected and the +48V phantom power is turned on, the battery life is about 24 hours. It is powered by a power adapter and used with 220v indoors; powered by a power bank; powered by DC 5v-12v.
