Description of SM4:

Samson’s SM4 is a half-rack, 4-channel line mixer designed to easily integrate into any installation or commercial sound system. This mixer is perfect for fitness clubs, gyms, restaurants, night clubs and schools. The studio-grade microphone channel features a 2-band equalizer (EQ) that allows you to adjust the tone of the microphone without affecting the music. The Music channel includes rear panel RCA inputs, and front-mounted stereo 1/4" and 1/8" inputs for connecting mobile devices. The Bluetooth connectivity lets you wirelessly stream music, while the USB port can integrate an optional Samson XPD Series wireless system or plug in a mobile device. A voiceover feature enables you to lower the music (up to 30dB of ducking) while talking through a microphone or USB port.

The Samson SM4 mixer incorporates a unique combination of features that just cannot be found in any other mixer at anywhere near the price. Featuring studio quality audio and exceptional build quality, the SM4 Voice-Music Bluetooth Mixer with Auto Talkover was designed for fitness studios, House's of Worship , schools, and business's where a vocal mic or headset/lavalier needs to mix with music and/or an AV presentation. The SM4 is built in a steel, half-rack chassis that was designed to mount next to a wireless mic receiver so all control sources are in one convenient location.

Many applications do not require a large mixer with multiple channels but may feed signal to large areas (auditoriums, churches, presentation-training rooms, restaurants and bars) or areas that need high power sound systems (fitness studios, spin classes, dance classes) . These applications need a mixer that is very easy to operate and incorporates a Talkover feature that ducks the music under the voice whenever signal is detected at the mic or USB input. It's like having a Front of House Sound Engineer working the system.

The integrated Bluetooth receiver allows for streaming from any Bluetooth equipped mobile device and the device can be continually re-charged from the front panel USB port. The SM4 can easily connect to existing systems via main mixer, floor /wall panel inputs, or even the single mic input on a DJ controller. Just switch The XLR and RCA stereo outputs to MONO and the mixer output can be sent to one mic or RCA input when used as a sub-mixer to a larger system.

Aerobics/Fitness Studios: Allows the instructor to mix the wireless headset with the music program (connected via Bluetooth, RCA rear jacks, 3.5mm front panel jack) and use the Talkover feature to duck the music under the mic rather than try to scream/yell over the music. This voice saving feature makes the SM4 the perfect partner for Samson Airline 88 and Airline 77 Fitness Headset systems.

Auditorium - Conference-Training Room / House Of Worship Podium Mixer: The SM4 allows the presenter to mix the podium mic with the computer audio signal via front panel (3.5mm stereo input) and send the mixed signal to the main system. The USB input allows a Samson XPD Series wireless lavalier, headset or handheld mic system receiver to be easily connected to the front panel.
