A setting of off doesn´t dampen thefeedback signal at all, while higher values generate a heavier dampening effect.5.1 Surround Delay Types The Surround Delay Types are only available on the FX2 unit.Along side current wide-spread use of stereo recording technology, multiple channel recordingtechniques have recently established themselves particularly in film audio. Thanks to the rise of DVD,consumer expectations of audio in general have increased. Music-only recordings done as surroundproductions are not unusual anymore. For this reason, the effects in the Q have been expanded toinclude two Surround Delays.The term „5.1“ means that 6 channels will be supported at the same time; 2 front speakers, 2 rearspeakers, and one center channel speaker build up the normal 5 tone channels (5.x) where theloudspeakers surround the listener in a circle. The sixth channel supports the so-called LFE channel(Low Frequency Effects) which is almost always connected to a subwoofer (x.1).To use the full performance of the surround delays please connect the Q´s audio outputs to yourmixing unit or to a special surround amplifier as follows:☞ Output setup of the Q when using the surround delays:• Main Out L+R outputs the signal for the front speaker L+R• Sub Out 1 L+R outputs the signal for the rear speaker L+R• Sub Out 2 L outputs the signal for the center speaker• Sub Out 2 R outputs the LFE signal for the subwoofer5.1 DelayThis delay type produces different echoes of the input signal and sends them to the correspondingaudio outputs of the Q (refer to the text above).Delay !Feedback1.48 s | 100.0 %Delay 1.4ms…1.48sSets the length of the SurroundDelay in milliseconds.Feedback 0…100%Controls the amount of signal that is routed back into the Delay line. Lower values therefore producefewer echoes than higher values.
