Audio Solution Sound Project: Model 2-2022 (SP2) 2-Channel Analog DJ Mixer

Audio Solution Sound Project SP2 Analog Rotary DJ Mixer

The Audio Solution Sound Project Model 2-2022 (SP2) is a handcrafted Italian 2-channel analog rotary DJ mixer for vinyl enthusiasts, DJs, and hi-fi listeners. It pairs discrete analog circuitry with ALPS RK27 Blue Velvet controls, a 3-band master isolator, and a brushed aluminum chassis with solid wood side panels.

Settle into a vinyl listening session or shape your next mix with rotary controls, dedicated booth and master levels, and an effects send/return loop that puts hands-on adjustment at the center of your setup.

Handcrafted in Italy. Available in Canada, the USA, and Mexico.

Key Features

• Italian craftsmanship: Heavy-duty, laser-engraved brushed anodized aluminum faceplates and CNC-machined solid wood side panels finished by Italian carpenters.
• Discrete analog construction: Traditional PTH (Pin-Through-Hole) assembly with no SMD components, built on a 70 µm dual-layer PCB.
• ALPS RK27 Blue Velvet potentiometers: Used on the primary controls and 3-band master isolator for smooth, tactile adjustment.
• Nichicon MUSE capacitors: Audio-focused components throughout the listed circuit design.
• Low-noise design: Precision 1% metal film resistors and a heavily filtered power bus.
• External linear power supply: Isolated supply with an adjustable 110V–220V selector, designed to reduce electromagnetic mains interference.
