Reflector6 is an extremely versatile delay and boundary effect for multichannel applications. Since it features no less than 6 outputs, it is compatible with a wide variety of audio formats, including 6.1 surround, 5.1 surround, LCR and stereo. Even though the 6.1 format uses 7 channels, you will still be able to use the Reflector 6 algorithm, as the sub channel is practically never treated with delay effects.
