Introduction
Automatic setup is now available in the Evolution 707. The new Krell Automatic Room
Equalization System (ARES) analyzes the speakers’ capability, position, phase and distance
relationships to determine ideal crossover points, delay, and volume settings. Listening room
surfaces, speaker positioning and construction play a pivotal role in the overall sound quality
of a system. ARES measures these effects against the inherent performance of the system’s
speakers and corrects for irregular surfaces, problematic speaker locations, and unusual floor
plans. Using the included calibration microphone, the ARES will automatically determine
the location and capability of the system’s speakers and optimize them to work ideally in the
room they are located. System memories allow multiple setup configurations for different
musical styles, seating positions, and speaker configurations. For older Evolution 707 units,
new firmware must be loaded into the unit. Please contact Krell for help in performing this
operation. Please read this document to learn how to take full advantage of them.

memories save the following information:
