CROSSOVER ROUTING OPTIONS
The Crossover User Interface is shown in FIG. 2B. Labels 1 and 3 indicate the selected way and outputs (Fig 2B shows
way 1 selected, outputs 1 AND 5). Each way has five modifiable parameters:
•
Pass-Band ‘a’ frequency in Hertz,
•
Slope ‘a’ (Butterworth 6, 12, 18, or 24; Linkwitz Riley 12 or 24) in dB/Oct.
•
Pass-Band ‘b’ frequency in Hertz,
•
Slope ‘b’ (Butterworth 6, 12, 18, or 24; Linkwitz Riley 12 or 24) in dB/Oct.
•
Gain (from –INF to +20) in dB.

CROSSOVER MODULE
Label 2 displays the selected parameter. Using the left-right keys in the Navimec changes to the next parameter, while
the up-down keys changes the parameter value. As shown in label 3, the effect of the changes to the parameters will be
refreshed in the graphic representation. The selected way is always displayed with a solid line, while the other ways are
displayed with a dotted line.
SUBHARMONIC SYNTHESIZER (SUBH)
The Subharmonic Synthesizer was developed to enhance the low frequency response of the audio. The module analyzes
signals in the range of 50 to 170 Hz, and generates lower frequency harmonics with a relationship to the main signal
determinate by the user-selected percentage. To direct-access this module, press the SUBH key, or select
Subharmonic Synthesizer in the main menu.
The Subharmonic Synthesizer User Interface is shown in FIG. 3. Label 1 indicates the parameter to enable/disable
synthesizer. Label 2 indicates the percentage of subharmonic content to be added. Use the up-down keys of the Navimec to
select the parameter, and the left-right keys to change the value.

SIGNAL COMPRESSOR (COMP)
The Signal Compressor processes the input signals in such a way that the amplitude of the signal changes at the user-desired
rate when the input signal is above the user-defined threshold. To direct-access this module, press the COMP key, or select
Compressor in the main menu.
This module features four modifiable parameters: Softknee, Threshold, Ratio, and Gain. The parameters affect both inputs
simultaneously.
