Outline GTA Quattro 4-Channel Touring Amplifier – 4 x 3000 W @ 4 Ω
The Outline GTA Quattro combines massive power with unmatched versatility. It is the ultimate all-in-one engine for subwoofers and high-output full-range systems. This is because of the universal multi-phase power supply, powerful on-board DSP and seamless Dante networking make
Gigantic Power, Compact Footprint
Firstly, delivering up to 4 × 3000 W at 4 Ω—or a staggering 10.4 kW in bridge mode—the GTA Quattro packs arena-level punch into one chassis. Furthermore, a damping factor >5000 and THD+N below 0.01 % keep every transient tight and transparent.
Universal Mains & Intelligent Protection
Moreover, the amplifier’s switch-mode supply with power-factor correction automatically adapts while balancing phase loads. This is from the 85 VAC club that feeds to 460 VAC three-phase stadium power. Additionally, comprehensive protection—thermal, short-circuit, DC, clip, over/under-voltage—safeguards your investment night after night.
Advanced DSP & Seamless Networking
An ARM Cortex-A8 processor plus TI C6000 DSP platform offers raised-cosine EQ, linear-phase FIR crossovers, TruePower™ limiters and up to 2 s of input delay. Route any analog, AES3 or redundant Dante stream via the 4 × 4 matrix, then take complete control over Ethernet, WiFi or the intuitive Armonía Pro Audio Suite™ mobile app.
