The secondary function for the MIX 2 knob sets the Dual Delay configuration. Press and hold both TAP and BYPASS footswitches while turning the MIX 2 knob to adjust. Turn left for Series, center for Ping Pong, or right for Parallel configuration.
In Series configuration, Delay 2 feeds Delay 1. This is equivalent to putting two single delay pedals in succession on your pedal board. A mono input feeds both left and right channels.
In Ping Pong Mode, the delays are configured in a series ‘ping-pong’ configuration. When using a mono output signal, this configuration is the same as the Series configuration. In stereo, each delay acts as a ping-pong delay, and they interact when both Mix knobs are turned up.
In Parallel configuration, the delays do not interact with each other, but produce their outputs ‘side-by-side’. In Stereo, Delay 1 outputs to the left channel, and Delay 2 outputs to the right channel. When the right output is not used, the wet signal sums to mono so that both parallel delays are heard from the left output.
