Logic ground is distinct from audio ground. Make all logic ground connections to this pin, including power supply
ground of external logic circuitry. To avoid switching clicks, do not connect logic ground to audio, chassis or rack
grounds. Logic controls are accessed through the high density DB-15 multi-pin connector on the rear panel (Figure
5). Pin connections are shown in the following table.
