QSC’s award-winning MXa Series amplifiers combine ultra-clean audio performance and unsurpassed reliability while delivering maximum power under the most demanding conditions.
FEATURES: • High-efficiency stepped linear outputs reduce amplifier cooling requirements and AC current draw by greater than 40%* Independent power supplies on each channel for greater reliability (split secondary on MX 1500a) • Power transistors direct–mounted metal-to-metal to heatsink for superior thermal performance • Level 1 Open Input Architecture for cost–and space–saving signal processing accessories* • Independent DC, subsonic, ultrasonic and thermal overload protection on each channel automatically protect amplifier and speakers • Patented Output Averaging short circuit protection • Automatic two-speed fan matches cooling capacity to thermal requirements. Rear-to-front air flow prevents rack overheating. • 1/4″ TRS and barrier strip balanced inputs for low noise • Comprehensive LED array monitors operation and performance • “Touch-proof” binding post output connectors THX approved for cinema applications • 3-year warranty plus optional 3-year extended service contract • Distortion (SMPTE-IM) Less than 0.05% • Damping Factor greater than 200 • Dynamic Headroom 3 dB at 4 ohms • Input Impedance 10 K ohms unbalanced, 20 K ohms balanced • Controls Front: AC Switch, Ch 1 and Ch 2 gain knobs • Back: Parallel/Stereo/Bridge Switch • Indicators POWER: Green LED • SIGNAL: Yellow LED, 1 per channel • CLIP: Red LED, 1 per channel PROT: Red LED, 1 per channel • Connectors (each channel) Input: 1/4″ TRS and Barrier strip • Speakers: Touch-proof binding posts • Amplifier Protection Full short circuit, open circuit, ultrasonic, and RF protection. • Stable into reactive or mismatched loads. • Output Circuit Type Complementary linear outputs: 2-Step Class H on MX 1500a • Power Requirements 100, 120, 230 VAC, 50-60 Hz • MX 1500a:19″ (48.3 cm) rack mounting, 3.5″ (8.9 cm) tall (2 rack spaces), 17.9″ (45.5 cm) deep
