About the GFA-7805
The Adcom GFA-7805 is a five-channel solid-state power amplifier designed for high-performance audio applications. It delivers 300 watts per channel into 8 ohms and 450 watts per channel into 4 ohms at 1% THD across the full audio spectrum (20Hz-20kHz). It features switch-selectable RCA and XLR inputs for each channel, 12V trigger input for remote power control, and multiway binding post speaker terminals. The amplifier is noted for its clean power delivery, wide and deep soundstage, and smooth handling of dynamic changes, although it has a slightly softened high-frequency response which can be beneficial in brighter listening environments. It weighs 88 lbs and measures 17" W x 8.75" H x 19.75" D. The GFA-7805 is praised for offering high power and sound quality at a relatively low price point, suitable for both two-channel and multichannel systems.
