The A500 Reference Amplifier is the ideal choice for recording studios, post-production suites, or anyone seeking audiophile-grade performance—without the audiophile-grade sticker shock.
Ultra-linear power amplifier for recording studios, post-production, live sound and HiFi application
2 x 300 Watts into 4 Ohms, 600 Watts into 8 Ohms in bridged mono operation
Servo-controlled design can drive virtually any passive speaker such as studio monitors, etc.
Advanced convection-cooling for absolutely noise-free and stable operation (no fan)
Precise level meter and clip indicators for accurate performance monitoring
Input connections on balanced XLR, 1/4'' TRS and RCA connectors
Speaker outputs on professional ''touch-proof'' binding posts and 1/4'' TS connectors
Ultra-reliable Toshiba / Fairchild power transistors
Independent thermal overload protection with LED indicator for each channel automatically protects amplifier and speakers
High-current toroidal transformer for absolute reliability and lowest noise interference
High-quality components and exceptionally rugged construction ensure long life
