Plug-in a wired microphone to the XLR-1/4" combo jack, or go hands-free by connecting a Samson XPD Digital Wireless* system to the front panel USB jack. The Music channel includes stereo RCA inputs on the rear panel, as well as front-mounted stereo 1/4" and 1/8" inputs. Lastly, stream audio wirelessly via Bluetooth.
Voice Priority:
The mixer includes a high-quality, bidirectional USB-C jack for interfacing with computers as well as tablets and smartphones that have USB-C ports. This allows you to record a mix, fly-in audio tracks for a presentation, or use the SM4U as a video conferencing mixer.
The Voiceover control offers priority ducking of up to 30dB while talking through a mic or using the XPD Wireless input. The Voiceover Hold knob lets you adjusts the active ducking hold time from 0.5 to 3 seconds. Whether you’re leading a group ex-class or making announcements, intelligibility is key.
Installed Sound:
The compact SM4U takes up just half of a 1U rackspace and can be installed using the included rackmount kit. It can be mounted adjacent to most Samson Concert 88/288 and Concert 99 series wireless half-rack receivers. The mixer includes stereo XLR and RCA outputs that can be configured for either mono or stereo operation. A rear-mounted Master Volume allows the overall output level of the mixer to be preset for the room or application without the worry of accidental changes.

Great small mixer for simple setups
Perfect for 2 mic setup (if you have the proprietary XPD wireless system). Simple setups allows you to set your max volume on the back of you don't want people cranking the volume too lound from the front knobs. Talk over feature only works for the corded mic. Would be nice if that feature also work...
