Alto L-16 24-Bit 16-Channel Live Sound Mixer with Digital Effects – Used, Great Condition

The Alto L-16 is a feature-dense, professional-grade compact live sound mixer designed for demanding stage, studio, and installation environments. Offering a robust signal path, flexible routing, and a powerful onboard digital effects engine, the L-16 delivers capabilities rarely found in mixers of this size. This unit is well suited for live bands, small venues, rehearsal spaces, houses of worship, and mobile sound applications where reliability and control are essential.

Built around ultra-low noise microphone preamps and a 24-bit internal DSP, the L-16 provides clean gain structure with excellent headroom and clarity. The mixer features 10 mono input channels equipped with gold-plated XLR microphone inputs, balanced TRS line inputs, switchable +48V phantom power, and 75Hz low-cut filters to reduce unwanted rumble and stage noise. Channels 1–8 offer 3-band EQ with sweepable midrange, allowing precise tonal shaping, while stereo channels are equipped with 4-band fixed EQ for consistent and musical adjustment.

Each channel includes Mute and Solo functions, along with Signal and Overload LEDs, providing clear visual feedback and intuitive control during live operation. 60mm high-precision faders ensure smooth, accurate level adjustments. For advanced routing, every mono channel includes inserts and direct outputs, making it easy to integrate outboard processors, recording devices, or expanded sound systems.

The L-16’s internal 24-bit DSP effects processor features 256 effects, organized into 16 presets with 16 variations each, covering reverbs, delays, modulation, and more. Effects can be routed internally or externally via AUX sends, with dedicated monitoring control and DSP mute functionality. A 9-band graphic EQ on the main output allows for system tuning and feedback control, making this mixer especially effective in live sound environments.

Connectivity and routing flexibility are standout strengths. The mixer provides 4 AUX sends per channel—two switchable pre/post-fader for monitors or effects, and two post-fader for DSP or external processing. Additional features include 4 stereo AUX returns, subgroup outputs, control room and headphone matrix routing, balanced XLR and TRS main outputs, and 2-track I/O with flexible assignment options. A 12-segment LED meter ensures accurate level monitoring at all times.
