SETUP SPEAKERS 1. Speaker Size The speaker setup menu defines how many speakers are installed in the system, the relative size of the speakers, and their location in the room. This is the most important setup procedure that will be performed. The preamplifier comes from the factory setup for 7 small speakers and a subwoofer . If this does not match[...]

2. Setup Speaker Location Ideally the speakers should be positioned at an equal distance from the listening position. However , physical limitations usually require placing the speakers in other than optimum locations. The surround processor contains a means to electronically move each speaker’s location. This allows for superior reproduction of [...]

LFE (0.1) channel level - Usually this will be set to 0.0 dB (default). However , if there is no subwoofer you may wish to reduce the Low Frequency Effect s (LFE) channel to lessen its contribution to the bass going to the remaining large speakers. Or , even with a subwoofer , you may just wish to reduce the overall LFE level, especially in a small[...]

The situation is different for large low-frequency peaks. These peaks are what tend to shake the knick-knacks off the shelves and result in an overall tubby sound to the bass. Fortunately , this CAN be remedied electroni- cally…and without drastically altering the characteristic sound of your speakers. T ypically a room will have 3 large peaks du[...]

SETUP INPUTS This menu allows you to tell your preamplifier how you would like each input to operate. Y ou may repeat the following steps for each input by changing input s on the top line of the menu or with the supplied remote control. 1.
