This feature is designed into the 6500 to eliminate system turn-on pops that can occur when several components turn on at the same time. 2. ( ((+ ++) ))1 112 22V VV C CCo oon nns sst tta aan nnt tt P PPo oow wwe eer rr - This is the main power input for the 6500 and must be connected to a (+)12V constant power supply. DO NOT connect this to a switched 12V source or the system may pop when the key is turned off. 3. R RRe eem mmo oot tte ee T TTu uur rrn nn O OOn nn I IIn nnp ppu uut tt - This is the input for turning on the 6500 and system amplifiers. It should be connected to the (+) 12V remote turn on output of the system head unit. The 6500 has a built in turn off delay to prevent turn-off pops. When the remote turn on signal from the head unit shuts off, the amplifiers will turn off immediately and the 6500 will stay on for five seconds before turning off. This feature is designed into the 6500 to eliminate system turn off pops that can occur when several components turn off at the same time. DO NOT connect this to a (+)12V constant power supply. 4. G GGr rro oou uun nnd dd - Connect this terminal to a quality ground location, preferably the chassis of the head unit, which must itself be properly grounded to the vehicle chassis. It is not recommended that the factory radio ground be used for after market audio components. 5. P PPo oow wwe eer rr F FFu uus sse ee - This fuse protects the 6500's on-board electrical components. Never replace this fuse with one of higher value or damage to the 6500 could occur and result in loss of your warranty. 6.

When set to high pass output the front and rear output crossovers are separately variable from 30 to 400Hz, by using the high pass frequency control knob (#5) on the front panel. © 2002 Directed Electronics, Inc 8.

Make sure the main source unit is connected to the Source 1 inputs, then adjust the main source units volume to just below maximum. 2. Adjust the Source 1 input gains (top of unit) to the minimum setting and the 6500 master volume control to the maximum setting. N NNO OOT TTE EE: ::If connecting more than one input source to the 6500, use the Source 1 gain controls to match the input level of both sources. 3. Set the filter gains to the flat (center) setting. 4. Complete all signal and power connection to the 6500. 5. Turn the system on and increase the gain on the Source 1 inputs until audible distortion can be heard. The system should be very loud at this time. 6. Reduce the 6500 master volume level and test for well-balanced and linear volume adjustment when using the Source 1 volume control. 7. When connecting a second source unit to the Source 2 input, the source one input gains (top of unit) may need further adjusting to achieve a close signal level match. © 2002 Directed Electronics, Inc CROSSOVER AND FILTER ADJUSTMENTS The crossover and filter gain adjustments can be performed two different ways, by using a piece of audio test equipment called an RTA (Real Time Analyzer) or by listening to a familiar piece of music. The RTA is most commonly used to achieve the flattest possible system response in preparation for a sound-off competition. Although an RTA may help in setting a flat system response, it does not allow for your personal listening preferences. When setting the EQ filter and gain controls using a familiar piece of music, adjustments can be made according the way you like the music to sound in relation to the vehicles acoustics and the type of drivers in the system. 1. Set all filter gain controls to their flat setting by adjusting all the filter knobs to the center or 0 setting when they are extended and set to their in position. 2. Set all frequency controls to their flat setting by adjusting all the filter knobs knobs to the flat or 0 setting when they are extended and set ...
