Samson 4-Channel Mixer with USB and Bluetooth Capability

The Samson SM4 is a four-channel mixer able to handle microphones, instruments, line-level signals, and Bluetooth streaming. On its front panel, you’ll find a stereo 1/4" connection for line-level sources, stereo 3.5mm jack for MP3 players, USB port for digital wireless receivers and smartphone charging, and a pairing button for Bluetooth devices. Controls offered on the front panel include separate volume knobs for microphone and music signals, a knob for bass boosts/cuts, and a similar knob for treble. You’ll also note the Voiceover knob, which automatically ducks the music channels when detecting signal on the microphone channel.
