The Power Dynamics PDM-M604A is an analog 6-channel studio mixer with a usb player, Bluetooth receiver and 7-band graphic equalizer. You stream music via Bluetooth or play the music from a USB stick. This allows you to easily add sound recordings that you then edit with the equalizers or effects. You record sound with a condenser microphone thanks to the 48V phantom power. This means that you record high-quality sound with a studio microphone. You connect a total of 6 microphones or 6 instruments to the mixer. There is a 7 band graphic equalizer on the master channel. With this you remove and accentuate frequencies, so you can easily find the balance between the high, medium and low tones.
