Versatile 4-Channel Mixer with USB and Bluetooth
The Samson SM4U MediaTrack is a powerful and compact 4-channel mixer designed to meet the needs of commercial sound installations, fitness centers, restaurants, nightclubs, schools, and more. Whether you need a reliable solution for background music, live announcements, or wireless audio streaming, this half-rack mixer offers a streamlined design with a user-friendly interface, making it an excellent addition to any professional audio setup.

Flexible Connectivity for Any Setup
The SM4U allows seamless mixing of up to four audio sources, featuring a balanced XLR-1/4" combo mic input with 15V phantom power, RCA inputs, and both 1/4" and 3.5mm stereo line inputs. The mixer's built-in Bluetooth receiver ensures quick wireless pairing with smartphones, tablets, and laptops for easy music playback, while the USB port supports the integration of Samson's XPD digital wireless microphone systems.

Voice Priority and Auto-Ducking for Clear Communication
Designed with professional environments in mind, the SM4U features a priority voiceover function that automatically lowers background music when the microphone is in use. This ducking feature ensures clear and intelligible speech during announcements or fitness instruction, making it ideal for gyms, restaurants, and event spaces where vocal clarity is essential.

Rack-Mountable Design for Easy Installation
Perfect for permanent installations, the SM4U includes a rackmount kit, allowing for easy side-by-side mounting with other audio equipment such as Samson’s CR88, CR288, or CR99 wireless receivers. The rear-mounted Master Volume control prevents users from adjusting levels too high, protecting both your audio system and speakers.

Optimized Sound Control with Built-In EQ
For enhanced tonal control, the mixer's mic input features a 2-band EQ with separate bass and treble adjustments. This allows you to tailor the microphone’s sound without affecting the overall music mix, making it particularly useful for instructors, presenters, and DJs who need a clear and well-balanced mix.

Multiple Output Options for Any Audio System
The SM4U is equipped with balanced stereo XLR and RCA outputs, along with a Mono/Stereo switch to accommodate a variety of speaker configurations. Whether you need stereo output for a full-range speaker system or mono output for a PA system, this mixer ensures compatibility with different professional audio setups.
