MX-1646D is a professional mixing console with 8CH mono and 4CH stereo inputs. MX-1646D features studio-class FX processor, phantom power for individual input channels, USB audio input, and built-in audio player/recorder in a compact package.
Input channels have high-quality equalizer for convenient sound making. The built-in audio player/recorder uses a USB or SD card as a medium and supports WAV and MP3(Player only) format. MX-1646D has a contact closure input to mute audio outputs, making the professional audio system co-operate with emergency broadcasting systems. MX- 1646D is suitable for small to medium size applications such as multi-purpose halls, school auditoriums, and small churches.
