Positive Grid Spark EDGE — Portable 4-Channel Smart Amp and PA System

The Positive Grid Spark EDGE is a 4-channel smart amp and PA system engineered for musicians needing a compact unit that handles guitar, bass, vocals, and acoustic instruments on stage, in rehearsal, or on the street. It pushes 65 Watts of Class D power through a custom 6.5-inch woofer and 1-inch horn tweeter, with a 120° sonic spread to fill small to medium rooms without a separate PA stack. This model is ideal for working solo performers and small bands wanting amp-grade tone, vocal capability, and looper functionality in a single 6.2 kg cabinet.

What Sets the Spark EDGE Apart

Inside the cabinet, a dedicated Sonic IQ computational audio chip manages dynamic range compression, bass enhancement, stereo widening, and Auto EQ. The amp reacts intelligently whether placed on a desk or tilted back as a floor monitor. Hardware arrives with 16 customizable presets divided into two banks per channel, and the Spark app unlocks 36 amp models, 50 effects, the Creative Groove Looper with hundreds of drum patterns, Spark AI tone generation, and ToneCloud access with more than 100,000 user-uploaded patches.

Power and Speaker Architecture — Loud Enough to Draw a Crowd

Surviving a real gig depends on power and cabinet design, not just bedroom playability. Spark EDGE pairs a 65W RMS Class D amplifier with a bass-reflex enclosure (two reflex ports) and a wide-dispersion coaxial-style woofer/tweeter combo, reaching 116 dB SPL RMS and 120 dB SPL peak at one meter.

• Power Output: 65 W RMS Class D — enough headroom to compete with an acoustic drum kit in a small rehearsal room
• Speaker Configuration: 1x 6.5-inch custom woofer + 1x 1-inch custom horn tweeter — handles low-end punch and articulate highs in one box
• With a Frequency Range of 45–20,000 Hz, the amp serves vocals and acoustic instruments as well as guitar.
• Max SPL: 116 dB RMS / 120 dB peak @ 1 m — projects clearly across a small to medium venue

Channels, Connectivity, and Battery — Perform Anywhere

Four channels and a generous I/O panel make this amp a true mini-PA. Channel 1 hosts the full 36-amp / 50-effects engine for electric, acoustic, bass, and vocals; Channel 2 is tailored for vocals, bass, and acoustic; Channels 3 and 4 accept stereo line-level sources such as keys or a drum machine.

• Inputs: 2x XLR / 1/4" combo, 2x 1/4" instrument, 5-pin DIN MIDI — covers mic, instrument, and MIDI control in one rig
• Outputs: 1/8" headphone, 2x 1/4" line out (L/Mono + R) — silent practice plus feed to an external mixer when needed
• Wireless: Bluetooth 5.0 + WiFi — streams backing tracks and pulls over-the-air firmware updates without a computer
• The Battery option (6,000 mAh Li-ion, up to 10 hours playtime, sold separately) unlocks cable-free busking and outdoor gigs.

Tone Engine, Looper, and App — A Modern Practice and Gig Ecosystem

What gives EDGE its edge over conventional combos is the DSP engine and Spark app ecosystem. Channel 1 supports up to three pre-amp effects, three post-amp effects, and one amp model per preset, while the onboard looper records up to 60 seconds on Channel 1 only.

• Amp Models: 36 on Channel 1, 3 on Channel 2 — covers electric, acoustic, bass, and vocal voicings from clean to high-gain
• Effects Library: 50 effects including Noise Gate, Compressor, Distortion, Modulation/EQ, Delay, Reverb — full signal-chain shaping without external pedals
• USB Audio: USB-C, 2 in / 2 out, 24-bit / 48 kHz — doubles as a Mac/Windows recording interface
• The Spark app features Smart Jam, Auto Chords, Spark AI, ToneCloud (100,000+ tones), tuner, and video capture for practice, songwriting, and sharing.

Who the Spark EDGE Is For

Designed for gigging solo artists, singer-songwriters who run a vocal mic plus an acoustic or electric guitar, and small-band rehearsal leaders seeking a single box that can keep up with drums. Buskers benefit from the optional battery, recessed carry handle, and the tilt-back monitor position. Coffee-shop and small-club performers get a real 65W PA with vocal presets instead of a fragile practice amp. Players already using a Spark 2 or Spark LIVE will find EDGE slots into the same app ecosystem, so existing presets and ToneCloud patches transfer over with a swipe.

Positive Grid and the Spark Ecosystem

Positive Grid built the Spark line around a connected app-and-amp ecosystem: the Spark app drives the Spark 2, the larger Spark LIVE PA, and now EDGE, with shared ToneCloud patches and over-the-air firmware updates. Positioned as the portable middle of that family — lighter than the 150W Spark LIVE, louder and more PA-capable than the Spark 2 — EDGE is designed to grow with optional accessories such as the Spark Battery, Spark Control X footswitch, Spark LINK, and swappable limited-edition grilles.
