PARASOUND HALO A21+ Stereo Power Amplifier Designed by legendary circuit engineer John Curl, the Halo A21+ refines Parasound's most celebrated power amplifier for today's systems - blending raw current delivery with effortless musicality. High-bias Class A/AB topology, dual-mono construction, and 2 ohm stability make it a benchmark choice for both demanding stereo systems and home theater front-channel duty. KEY FEATURES - High-bias Class A/AB topology designed by John Curl for pure, detailed sound - Dual-mono construction with separate power supplies per channel for low distortion and high channel separation - 1.3 kVA toroidal transformer with 108,000 uF of filter capacitance - Stable down to 2 ohms - drives demanding, low-impedance loudspeakers with ease - Balanced XLR and unbalanced RCA inputs, plus single-ended loop output for multiamping - Bridgeable to mono for up to 1000W into 8 ohms - 12V trigger input and auto turn-on circuit for system integration - Heavy-duty five-way binding posts, hand-tighten capable SPECIFICATIONS Power Output 300W/ch @ 8ohm, 500W/ch @ 4ohm, 1000W @ 8ohm (bridged) Topology Class A/AB, Dual-Mono Frequency Response 20Hz - 20kHz, +0/-0.25dB Voltage Gain 29dB (unbalanced), 35dB (balanced) Input Sensitivity 1V (balanced or unbalanced) Damping Factor >1100 @ 20Hz THD <0.1% @ full output Signal/Noise (A-weighted) >115dB Inputs Balanced XLR / Unbalanced RCA, with loop output Dimensions (W x H x D) 448 x 197 x 508 mm Net Weight approx. 32.2 kg Warranty 5 Years, Parts & Labor BRAND HERITAGE Founded in 1981 by Richard Schram, Parasound's flagship Halo line was developed with circuit designer John Curl beginning in 1988. The A21+ succeeds the original A21, which held a fifteen-year run as a benchmark of price-to-performance in high-end power amplification - refined with a larger transformer, increased filter capacitance, and lower distortion for today's systems.
