Get the party started with the SM4 4-Channel Mixer. It can be easily integrated into any installation/sound system. The mixer is incredibly versatile. You can stream and play music by connecting your media players or mobile phones via a wide range of on-board inputs. Bluetooth connectivity means you can even stream tracks wirelessly! No matter how loud the music may be youll always be centre of attention. The inclusion of a voice-ducking system automatically reduces the volume of the music when you make an announcement using a microphone. You can even sculpt your voice with the on-board equalizer for maximum clarity. If you want a great sound at a cost-effective price then look no further than the Samson SM-4!
