Mix It Up

Samson's SM4 is a half-rack, 4-channel line mixer designed to easily integrate into any installation or commercial sound system. Perfect for fitness clubs, gyms, restaurants, night clubs and schools, the SM4 features a balanced microphone channel with 2-band EQ, voiceover priority ducking, stereo line level inputs, as well as Bluetooth® and Samson Stage XPD wireless connectivity.

    • Bluetooth Streaming - The Bluetooth receiver has a range of approximately 100’ (30m)
    • USB Port - For Samson Stage XPD Series USB Digital Wireless Systems (sold separately) or charge your phone

Convenient Connectivity

The SM4 allows you to mix up to four channels of crystal clear audio. The mixer's studio-grade Mic channel features a 2-band EQ (Bass and Treble) to adjust the mic's tone without affecting the music. The Music channel includes rear panel RCA inputs, as well as front-mounted stereo 1/4" and 1/8" inputs for easily connecting mobile devices. Bluetooth connectivity lets you wirelessly stream music, while a USB port allows you to integrate an optional Samson Stage XPD Series wireless system.

Voice Priority

Whether you're leading a group exercise class or making announcements at a restaurant, intelligibility is key. The Voiceover feature enables you to lower the music (up to 30dB of ducking) while talking through a mic or using the XPD Wireless input. The Voiceover Threshold knob lets you adjusts the active ducking hold time from 0.5–3 seconds.

Installed Sound

For fixed installations, the SM4 can be installed using the included rackmount kit. It can be mounted side by side with a Samson CR88, CR288 or CR99 wireless receiver. The mixer's rear-mounted Master Volume control allows you to set the overall output level of the mixer, and stopping users from playing the system too loud and destroying your speakers. It also features stereo XLR and RCA outputs, and a Mono/Stereo switch for use with a mono sound system.
