A21 Signature Line and Integrated Amplifier
The Sugden pure class A design provides affordable high-end performance from a beautifully engineered single box integrated amplifier. Compact in size with a simple but stylish design, the A21 is possibly the only amplifier you will ever need. With many of the original A21’s still in daily use after fifty years, it could also last a life time. Providing a large soundstage and depth to all types of music, the A21 is an amplifier you can listen to for hours without fatigue. The single ended voltage rail circuit provides impressive dynamics and incredible bass.
The A21 Signature integrated amplifier is available with or without a MM/MC phono input. Without a phono input it is designated the A21L (line input only). A21aL models can be fitted with a phono input at a later date.
Facilities
Inputs Five line level (four on A21 Integrated)
Optional mm/mc phono
Outputs One pair of stereo multi-way binding posts
Pre-out (variable), tape out (fixed)
Remote Control Volume up/down
Earth terminal
Specifications
Line Input Sensitivity 170mV for max. out
Phono Input Sensitivity 3mV/mm, 0.2mV/mc for max. output
Phono Loading MM 47K MC 100 Ohm
Power Output 23 Watts into 8 Ohms
Frequency Response +/-1dB 10Hz-20kHz
Bandwidth 6Hz-200kHz
Signal to Noise >83dB
Gross Weight (packed) 11kgs
Dimensions 92 x 430 x 350mm (hwd)
Tipper ut fra andre rene Klasse A forsterkere at Output Power halveres ved 4ohm kontra 8ohm. Dvs ca 11watt. Så da er høyttalermatch viktig. Mine er på 95db og typist 8ohm. Aldri under 4ohm. Burde derfor gå bra.
