ALL IN ONE CHASSIS
A preamplifier, amplifier, phono stage, and digital to analog converter all in one chassis, the GSi75 combines with your favorite speaker to deliver a singular and simple solution to control your listening system. Unlike other integrated designs that make performance – sacrificing compromises to fulfill a price point or form factor, the GSi75 harnesses the power and technologies developed by Audio Research into an authoritative platform to reveal the performances in your media.
Powered with the new KT150 output tube, the GSi75 supplies finesse and control that belies the 75-watt per channel power rating. The digital-to-analog converter will handle almost any sampling frequency including DSD. The phono stage and headphone amplifier round out the GSi75, providing total system control and integration. The elegant, understated industrial design will complement the rest of your system both visually and sonically.
Podrobnosti o izdelku
75 watts per channel continuous from 20Hz to 20kHz. 1 kHz total harmonic distortion typically 1.5% at 75 watts, .05% at 1 watt. Approximate actual power available at “clipping” 80 watts (1kHz). (Note that actual power output is dependent upon both line voltage and “condition” i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
POWER BANDWIDTH (-3dB points)
12Hz to 70kHz.
FREQUENCY RESPONSE (-3dB points at 1 watt)
