Soundking AM20 Mixer digital

Soundking AM20 — Compact Digital Mixing Console for Live, Recording, and Broadcast

The Soundking AM20 is a compact digital mixing console engineered for small-to-medium live sound, studio recording, livestreaming, and corporate meeting rooms. A 4th-generation 40-bit SHARC floating-point DSP at 450 MHz pairs with an ARM Cortex-A53 quad-core SOC for low-latency 20-channel processing. Sixteen local inputs (12 XLR + 4 Combo), eight balanced XLR outputs, and AES/EBU digital I/O feed a 10.1-inch 1280×800 capacitive touchscreen that drives the workflow.

What Sets This Console Apart in Its Class

Two architectural choices distinguish this digital mixer from typical compact desks. First, the dual-processor design pairs a dedicated 40-bit floating-point SHARC chip with a quad-core ARM Cortex-A53 SOC, so DSP-heavy channel processing and UI tasks never compete for the same silicon. Second, the 10.1-inch capacitive touchscreen runs the interface with an RTA spectrum display on a professionally customized Android system.

Inputs and Outputs — Flexible Connectivity for Hybrid Setups

Sixteen local inputs split into 12 XLR and 4 Combo jacks, each with individually switchable +48 V phantom power. Eight balanced XLR outputs are freely configurable, and independent AES/EBU input and output carry digital signals without an extra converter.

• Local Inputs: 16 channels (12 × XLR + 4 × Combo) — covers band, panel, or studio mic counts without stage boxes
• Local Outputs: 8 × balanced XLR, freely assignable — drive main PA, monitors, and recording feeds
• Digital I/O: AES/EBU in/out + USB recording and playback — digital patching and USB flash drive capture
• Phantom Power: individually switchable +48 V per channel — adapts to dynamic and condenser microphones

DSP Engine and Channel Processing — Studio-Grade Headroom

The 40-bit floating-point word length preserves headroom through aggressive EQ and dynamics moves, while the 450 MHz SHARC clock keeps round-trip latency low for in-ear monitoring. Each input channel ships with a 4-band parametric EQ, a gate, a compressor, high- and low-pass filters, switchable phase inversion, and adjustable input delay.

• DSP: ADI 4th-gen SHARC, 40-bit floating point, 450 MHz — ample headroom for complex shows
• Coprocessor: ARM Cortex-A53 quad-core SOC — keeps UI and network tasks off the audio DSP
• Channel EQ: 4-band parametric per input — surgical tone shaping on every source

Control Surface, Buses, and Effects — Hands-On Workflow

Nine 100 mm motorized faders, SEL/SOLO/MUTE buttons per channel, and a dedicated master section give engineers familiar analog-style control in a 475 × 364 × 156 mm chassis weighing 7.3 kg. Five user layers reassign the eight physical channel faders to any inputs, groups, or auxes, while 12 user keys map common actions such as scene recall or channel mute. Bus architecture covers 4 AUX, 4 GROUP, 2 FX, and MASTER L/R, supported by 4 DCA and 4 mute groups.

• Faders: 9 × 100 mm motorized, auto-positioning on scene recall — fast scene changes
• Buses: 4 × AUX / 4 × GROUP / 2 × FX / MASTER L/R — covers monitors, effects, and sub-mixes
• Effects: 8 modules — 2 reverb, 2 delay, 2 modulation, 2 graphic EQ — assignable anywhere
• Groups: 4 DCA + 4 mute groups — efficient control over sub-mixes

Who Should Choose This Digital Mixer

The AM20 is the right choice for sound engineers, AV integrators, and small-to-medium venue operators who need powerful processing in a compact footprint. Houses of worship, corporate AV teams, broadcast studios, livestreaming setups, and touring bands running their own FOH will find the 16-input / 8-output architecture generous without being oversized. HTML5 browser remote control means a tablet or laptop can mix from the audience, while dual-console hot backup over a wired or wireless link protects critical events.

Soundking — Expandable Compact Console

Soundking pairs a dedicated SHARC processor for audio with a quad-core ARM SOC for system control, bringing processing typical of larger desks into a compact chassis. An expansion slot for optional Bluetooth or stereo sound cards, USB recording and playback, and scene import and export keep the platform ready for changing needs.
