Special Design Features
Since each channel of the amplifier is delivering current into its load only over a limited range of frequencies, several forms of distortion are reduced as com- pared to each channel handling the full range of musical information

Wisdom System Configuration
Follow the on-screeninstructions, as shown below
When you select a particular speaker location, the chosen speaker will be high- lighted and the right-handpanel will change to show you the various possibili- ties available for that speaker, as seen below
A “GenSW” option is also provided, so as to accommodate the use of one or more non-WisdomAudio subwoofers

Do not connect the microphone to the SC-1at this time, since feedback may result that could potentially damage your loudspeakers
Once you reach the Job Information screen shown above, you can safely con- nect the microphone to the SC-1
The Measurement screen is where MultEQ Pro collects the data it requires for accurate room correction. At this point, your installer will connect an XLR cable between the mic preamplifier LINE OUT connector and the Left input of the SC-1the top-leftcorner as seen from behind
phone was calibrated at “grazing incidence” and should point to the ceiling, not at any of the speakers
Measuring some distant corner where no one would be listening, or close to a room boundary such as a wall or floor, is actually counterproductive. It will compromise the quality of the resulting room correction
Distance can be displayed in feet, in milliseconds, or in meters cycle among these choices by clicking the blue underlined column label. Which one is best depends on the information your surround processor’s menu system needs. Use the appropriate value to set the distance delay in the preamp/processor
Once the room measurements are completed, MultEQ Pro calculates an equal- ization filter for each loudspeaker channel, including the subwoofers. The role of these filters is to achieve a particular frequency response within the entire listening area for each loudspeaker. This curve is determined based on several acoustical and program material considerations and is called a target or calibra- tion curve
boost in the bottom octave before you get too carried away with this setting
Once the software finishes calculating the optimal correction filters for the target curve you have selected, you will be presented with the Save Results screen shown above

This response would blend nicely with a subwoofer, crossing over at 50 Hz. It would also be improved by moving the microphone around as you normally do, so as to give the system more information about what is going on in the room
