Lfe (Sub Woofer Speaker); Linkwitz-Riley (Linkwitz) - Yamaha DME Designer Owner's Manual

Chapter 6 Component Guide
Knee
In compressors, de-essers, and expanders, sets the way in which compression or expansion will be
applied after the signal exceeds the threshold. The following range of settings is available: HARD, 1,
2, 3, 4, 5.
If Hard is set, the signal level changes to a straight line following the specified slope when the trigger
signal exceeds the threshold.
If a value between 1 and 5 (5 = softest) is specified, the curve gradually changes when the threshold
is exceeded, producing a more natural sound.
Components: Compander, Compressor, Ducking, Expander, Gate, Limiter

LFE (Sub Woofer Speaker)

This is a special speaker for playing back low frequency sounds.
Component: Surround 5.1, Surround 6.1

Linkwitz-Riley (Linkwitz)

One type of filter characteristics. As second-order filters, the sum of the output voltages for LPF and
HPF have a gain of 0bB across the entire band. The pass band is flat, but the cutoff frequency gain is
-6 dB.
Components: Crossover, Crossover Processor, Crossover Processor II, Programmable BPF,
Programmable HPF, Programmable LPF, Speaker Processor
Pan
Sets the distribution ratio of the input signal between right and left.
Components: LCR, LR, SPX
Pan Nominal Position
Sets the 0 dB reference for pan. There are two selections available, [Center] and [LR] (LR Nominal).
Center nominal uses the center volume as a reference. The means the center volume is 0 dB, and the
LR speakers are -3 dB.
LR nominal uses the LR speaker volume as the reference. The means the LR speaker volume is 0 dB,
and the center is +3 dB.
Components: LCR, Surround 3-1, Surround 5.1, Surround 6.1
Phase
Reverses the phase of the signal. If you turn this ON, signal is inverted. If you turn this OFF, the signal
is not inverted.
Components: Crossover, Crossover Processor, GEQ, PEQ, BPF, HPF, LPF, Notch,
Programmable BPF, Programmable HPF, Programmable LPF, Fader, Auto Mixer, Delay Matrix,
Matrix Mixer, Slot Output, Unit Output
Q
Sets the frequency bandwidth that will change the sound. As the value gets larger, the width gets
narrower and the curve becomes steeper.
In the parametric equalizer, this sets the frequency width where the gain will be cut or boosted. When
Q is widened, the gain is boosted or cut along a wide range centering on the frequency set by the
frequency setting, resulting in a large change in the tone quality. When Q is narrowed, only a specific
frequency is boosted or cut.
