Description
The Samson SM4 is a 4-channel mixer designed for installed and commercial audio systems that require simple control and flexible input options. Its compact half-rack design allows it to be integrated into racks or mounted alongside compatible wireless receivers. The mixer features a microphone channel with a 2-band shelving EQ, allowing users to adjust bass and treble without affecting other audio sources. A 15V phantom power supply supports compatible microphones connected via the XLR-¼" combo input.
The music channel includes multiple input options, such as rear RCA inputs and front-panel 1/4" and 3.5mm stereo inputs, making it easy to connect devices like smartphones, tablets, or media players. Bluetooth connectivity allows for wireless audio streaming without additional cables.
A built-in voice priority ducking function automatically reduces music levels (up to 30 dB) when speech is detected, helping improve clarity for announcements. The adjustable threshold control allows users to set how long the ducking remains active.
For installed sound systems, the SM4 includes a rear-panel master volume control, allowing system integrators to set a fixed output level and prevent unintended volume changes. It also includes stereo XLR and RCA outputs, along with a mono/stereo switch for different system configurations.
The front-panel USB port can be used for charging devices or connecting optional Samson XPD wireless systems, adding flexibility to the setup.
