Either way, you have just calibrated the system so that the maximum system out put occurs at the same point as the maximum output from the source. This will give you minimum system noise yet the system will reach its maximum output capability. 8. Reduce the source unit volume to a comfortable listening level. With the balance and fader controls still centered, adjust the remaining level controls for the proper system balance. If you are adjusting a system with multiple amplifiers, it is easiest to adjust the controls in the following order: 1. Front speakers 2. Rear speakers 3. Subwoofers 9. If using an AC502 remote level control, adjust the subwoofer level with the AC502 in the mid position. This will give you the ability to boost the subwoofer level approximately 6dB when the AC502 is turned fully clockwise. 10. Double check your system levels by increasing the source unit volume control to the previous ly determined maximum position. If you hear distortion from any of the channels, reduce the PowerPlateTM input level for those channels until the distortion goes away. Adjusting the input levels in this way will get maximum undistorted output from your system and will make it unlikely that you will cause damage to any of the components of your system by overpowering them. System 3 – P650 used in 3-channel mode. Channels 1/2 and 3/4 are high-passed and bridged for front speakers. Channels 5/6 are low-passed and bridged for a single subwoofer. P850 system diagrams Using the AC502 (optional) System 1 – P850 used in 6-channel mode. Channels 1/2 are high-passed for front speakers channels 3/4 are high-passed for rear speakers, and channels 5/6 and 7/8 are bridged low-pass for sub- woofers. Although shown with 4-channels of input, the source unit can be either 2- or 4-channel. System 2 – The P850 is used in 8-channel mode. Channels 1/2 are high-passed for front tweeters. Channels 3/4 are band-passed for front midrange. Channels 5/6 are high-passed for rear speakers, and channels 7/8 are low-passed for subwoofers. Although shown as a 4-channel input, the source unit can be either 2- or 4-channel. The AC502 remote level control, available as an accessory from your a/d/s/ dealer, may be used with your PowerPlate™ to remotely adjust the level of your subwoofer. On the P450, the AC502 will control the level of the low-pass output of the 3/4 crossover. If the 1/2 crossover switch is in the 3/4 position the 1/2 level will also be controlled. You can use P450 as a bridged two channel subwooofer amplifier this way. On the P650 the AC502 will control the level of the low-pass output of the 5/6 crossover. On the P850 the AC502 will control the level of the low-pass output of the 7/8 crossover. To use this feature, simply connect the AC502 into the DIN connector on the Powerplate and install the AC502 in the desired location. Refer to the "adjustments" section for information on setting up the AC502 for the appropriate adjustment range. tuning tuning the crossover All of the crossover controls in the multi-crossTM crossover section are marked at four reference frequency points. These are 45Hz, 175Hz, 600Hz and 5,000Hz. Specific crossover points should be chosen based on the operating range recommended by the manufacturer of your speakers. The 85Hz position is a good starting point to use for subwoofer low-pass or midrange high-pass use. When bi-amping a/d/s/ loudspeaker components 2500Hz is a good starting point for the midrange low-pass, and 3500Hz is recommended as the tweeter high- pass. Once installed, you can fine tune the crossover points using your ears or with the aid of an RTA to achieve maximum performance. With any loudspeaker, minor deviations from the recommended frequency ranges may provide superior results, depending on your speaker locations and your vehicle’s acoustics. Setting crossover frequencies higher than recommended will not cause damage and may provide good results. However, DO NOT set high-pass tweeter crossover points below the tweeter’s recommended operating range. Doing so will likely cause damage not covered by the manufacturer’s warranty. If you are using non-a/d/s/ speakers, refer to the manufacturer’s recomme...
