Key Features of the Alter 500

New Settings and Advanced Functions

Its ratio selector offers six positions, including two additional options compared to the original 1:1 and 2:1 settings of the 1176. A "Slam" mode can be activated via a dedicated switch, independent of the ratio settings. Attack and release times are selectable among "Fast," "Mid," and "Slow" using a three-position switch.

Innovation and Precision

It features a front-panel relay bypass switch. The input benefits from modern low-noise op-amp balanced circuitry, while the output is equipped with a custom IGS transformer. The circuit includes two stages of discrete 990-based amplification with output control between stages. Gain reduction is visualized by a 20-LED bar graph.
