AMPLIFIER CONFIGURATION

LRx 4.300 configuration occurs through two switches, IN SELECT and X-OVER, located under the setting panel.

•IN SELECT switch (1 IN - 2 IN) permits to use the preamplified output (OUT) as additional input (IN B). In this case, you will be able to realise a Front + Sub system, where IN A input drives Front, while IN B input accepts the possible subwoofer output, to be filtered at 24dB through F1 Slope switch in the controls panel and to be adjusted through the head unit Fader. IN B input can also

be used to make a full range, Front-Rear system, which will be driven by two full range signals by bypassing crossovers (X-OVER on OFF). These signals will have to be suitably filtered through external crossovers.

•X-OVERswitch activates (ON) the two Lo-Pass and Hi-Pass filters, indicated by F1 and F2 respectively in the controls panel. When F1 and F2 crossovers are off (X-OVER on OFF), you have full range signals on the amplifier power outputs.
