Historical Context and Positioning in the Range
"Spark Live" extends the DNA of Positive Grid's smart combos by adapting it for stage and events. Following models focused on practicality and studio use, this version enhances power, acoustics, and system versatility to cover rehearsals, live performances, and light sound reinforcement, while remaining compact.
Target Audience
Ideal for guitarists and bassists seeking consistent sound from the living room to the stage, it also suits singers and keyboardists thanks to dedicated inputs. Perfect for bands rehearsing, bar/club sets, mobile gigs with battery power, and home studio creators via USB. Targeted styles: pop, rock, funk, soul, blues, urban and acoustic music, where a clear, defined sound and sufficient headroom are desired.
Features and Innovations
Spark Live combines amplifiers, effects, and a mixer into a single combo. The Sonic IQ engine relies on a dedicated computational audio chip to automatically adapt the response according to the source (guitar, vocals, keyboards) and placement. Integrated processing includes dynamic range compression, auto-EQ via G sensor, virtual bass boost, vocal intelligibility enhancement, and stereo widening. Connectivity includes 3 instrument inputs in 1/4" format, 1 combo XLR/Jack input for mic/line, 1/8" headphone output, 1/4" line outputs L/Mono & R, 5-pin MIDI DIN ports (In/Out), Bluetooth 5.0, and a 2-in/2-out USB audio interface at 24-bit/48 kHz compatible with MacOS and Windows. The line outputs allow driving a front-of-house system while maintaining onstage control.
Sound
With its Class D amplification and FRFR (full range, flat response) configuration, Spark Live delivers a
precise, full, and balanced range, clear highs driven by horn-loaded tweeters, and deep lows thanks to dedicated woofers and reflex ports. The built-in amps and effects cover clean tones with high headroom, dynamic crunch, and controlled overdrive, while the Sonic IQ processing optimizes response and dispersion to maintain definition and impact at both low and high volumes.
