Zapco Z-1100.1 AP Class AB Full-Range Mono Amplifier

Highlights

Description

The Ultimate SQ AmpFor the new Z-AP series amplifiers ZapCo took the best of their LX amps and tweaked the circuitry to perfection. In the signal path they replaced the electrolytics with the high-end WIMA poly caps and used a new low-noise audio op-amp for the input stage with the smoothest audio op-amp they could find. They doubled the output drivers and increased the operating voltage of the matched final output devices. To get heat off the output devices faster and increase efficiency they used a new aerospace insulator. At the differential input stage they used 0.1% resistors not 1% but 0.1%… to assure the lowest possible floor. They developed our own patented multi-ground RCA connectors with extra heavy gold plating for perfect signal transfer. Zapco even improved the low noise gain pots had added detents to make watching levels a breeze. To top it all off they gave it a new look with a matt black finish and a solid copper plate with the logo and serial number engraved for posterity.FeaturesClass-AB Full-Range Mono AmplifierPower @ 4: 650 wattsPower @ 2: 1100 wattsPower @ 1: 1600 wattsSignal to noise ratio of over 110dBCoupled the output driversHighest HFE (Gain) Sanken selected output devicesDifferential balanced input stage0.1% resistors for lowest possible noise floorTI LME49720 (BJT) op-amps on the inputsTI LME49720 (BJT) op-amps in the signal pathWIMA MKS2 series caps in the signal pathExtremely low ESR caps throughoutProprietary patented RCA connectorsWhat’s in the BoxZ-1100.1 AP Class AB Full-Range Mono AmplifierManualSpecificationsPower @ 4: 650 wattsPower @ 2: 1100 wattsPower @ 1: 1600 watts *THD @ Rated Power: 1%Signal to Noise Ratio: 110dBFrequency Response: 10Hz to 30000Hz 1dBInput Sensitivity: 1v to 9vDimensions (W x H x D): 7.48 x 2.44 x 18.89*AP amplifiers are stable at 1 only when used with music signal and with proper ventilation.
