Parameters Used in the 960L Algorithms, Continued

FbckL,	Echo Feedback. Some reflection delays have echo capabilities. These appear as part of the
FbckR,	input path; echoes are passed to the reverberators as well as the reflection outputs. Also,
FbckLF,	echo signal is fed back through the input diffusors. This means that each echo will be more
FbckLS,	diffuse and spread than its predecessor. The control EchoLS sets the duration of an echo
FbckRF,	(that is, a feedback path) on the Left Surround Input and FbckLS sets the amount of feedback
FbckRS	for that path. Any echo pattern set with EchoLS and FbckLS will be heard in the surround
	reverb field and also in any reflection delay whose source is the Left Surround Input.
FbkMST	Echo Feedback Master scales all the echo feedbacks by a single percentage, allowing this one
	parameter to set the feedback of a complex pattern.
FrRoll	Front-channel Rolloff (surround algorithms only). Like Rolloff in stereo, it controls the cutoff
	frequency of a 6dB per octave low-pass filter at the output of all processing. In the Surround
	algorithms, there are separate controls for the front (LF, C, and RF) channels (FrRoll) and rear
	(LS and RS) channels (RearRoll).
FrRvb	Front Reverb Level (Surround algorithms only) controls the level of the reverberant tail, but to
	just the LF and RF outputs. This allows their levels to be set relative to the early reflection
	levels and the other reverb tails. We recommend setting the Front Reverb Level and the Rear
	Reverb Level approximately equal, with the Center Reverb Level less by about 4.5dB. RvbLvl
	is a master control for CtrRvb, FrRvb and RearRvb.
FSDly	Front-to-Surround Delay (Ambient Chamber only) In surround ambiences, there is a signal
	path from front inputs to rear early reflections and also from rear inputs to front early
	reflections. The level of this path (in both directions) is set by FSLvl. The high frequency
	rolloff is set by FSRoll. The delay in the path (in both directions) is set by FSDly.
FSLvl	Front-to-Surround Level (Surround Ambience and Ambient Chamber only) In surround
	ambiences, there is a signal path from front inputs to rear early reflections and also from rear
	inputs to front early reflections. The level of this path (in both directions) is set by FSLvl. The
	high frequency rolloff is set by FSRoll. In Ambient Chamber, the delay in the path (in both
	directions) is set by FSDly.
FSRoll	Front-to-Surround Rolloff (Surround Ambience and Ambient Chamber only) In surround
	ambiences, there is a signal path from front inputs to rear early reflections and also from rear
	inputs to front early reflections. The level of this path (in both directions) is set by FSLvl. The
	high frequency rolloff is set by FSRoll. In Ambient Chamber, the delay in the path (in both
	directions) is set by FSDly.
InLvl	Input Level sets level for all input channels simultaneously. Used to prevent processor
	overload by counteracting gain increases caused by high RTMid, BassMult, and Delay
	feedback levels. Unless extreme values of these controls are used, we recommend that you
	leave InLvl set at the factory preset position.
