Pink (Noise) Gen(erator)
Pink noise can be routed to any output channel(s) by using the Matrix Switcher. In Figure 9 the Pink Gen input
has been assigned to (turned on) in processor channel D, which is assigned to Outputs 1 and 2, renamed Dining
- L and Dining - R. Pink noise is now playing on the speaker pair in the Dining Room, to assist in setting levels or
equalization.

Parametric Equalizer
The Lexicon DD-8+ features a 10-band parametric equalizer (PEQ) on each processor channel that can be used
to compensate for loudspeaker deficiencies, room acoustics, asymmetrical speaker placement and other factors.
Equalization can vastly improve the sound quality of an audio system when skillfully used. Used incorrectly, an
EQ can make a system sound bad and may damage the loudspeakers. Use caution when using the PEQ feature
particularly if you have little to no experience with their use. Be gentle, especially when boosting gain.
NOTE: If you do not have a Real Time Analyzer and/or do not have experience in setting up equalizers you
should not attempt to use the PEQ. Consult a sound engineer, retailer or integrator who has the necessary
equipment and experience. Misuse of the PEQ may result in amplifier and/or loudspeaker failure.
The interactive frequency response graphs above each PEQ control panel provide visual feedback of the changes
effected by the PEQ, Bass and Treble controls and Output Filters. Use a Real Time Analyzer with the DD-8+’s built
in PINK (NOISE) GEN(ERATOR) input to achieve flat measured response and pleasing audible performance. While
measurably flat frequency response is a great starting point, user and audible subjective preference should be
the final arbiter. Trust your ears.
