Samson SM10 – 10-channel stereo line mixer in a 1U rack with 2 microphone preamps, 2 aux sends, and balanced XLR/TRS outputs

The Samson SM10 is a 19" rackmount line mixer featuring 10 stereo channels with balanced 1/4" TRS inputs, channel balance controls, and two channels with combo XLR/TRS mic preamps and +48 V phantom power . Each channel 1–8 offers +4 dBu / −10 dBV level switching to suit professional or consumer equipment. In the master section, the SM10 adds two aux sends ( MON pre-fader and EFX post-fader), balanced XLR and TRS main outputs , rear-panel stereo MON and EFX outputs , plus a front-mounted mono MON OUT with dedicated level and independently controlled headphone output and 6-segment meter . The MIX B bus can be reassigned via the MUTE/CLIP/MIX B button and selected as a monitor source, making it easy to create alternative submixes for recording, PA, or monitoring.

Built in a rugged 1U metal chassis with internal 120–240 VAC power supply , the SM10 is a reliable solution for fixed installation , keyboardists needing a submixer, guitar racks , multi-source podcast studios, or live sound where multiple stereo signals need to be grouped with flexible routing and low noise.

Frequently Asked Questions

• Are the MON and EFX sends stereo? Yes, they have L/R outputs on the rear panel; there's also a front MON OUT (mono) with its own level.
• Can I chain two SM10s together for more inputs? Yes. The LINE IN jacks on CH 9–10 allow you to link units without occupying channels 1–8.
• Does it have EQ per channel? No. It's a line mixer with level/balance controls and auxiliary sends.
