Anleitung Zusammenfassung
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 previously 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. Constant bass circuit To mix sub-bass information into channels 1/2 and 3/4, select a low-pass crossover point, and use the level controls to set the level of sub-bass signal sent to channels 1/2 and 3/4. Using the AC502 (optional) The AC502 remote level control, available as an accessory from your a/d/s/ dealer, may be used with your PowerPlateTM to remotely adjust the level of channels 3/4, OR to remotely adjust the constant bass level. To use this feature, simply connect the AC502 into the DIN connector on the PQ40, and install the AC502 in the desired location. To adjust the constant bass level, Locate the AC502 control switch on amplifier and push IN, or leave it OUT to control the level of channels 3/4. This remote capability can also be used on channels 1/2 when the PQ40 is used in the 2-channel bridged mode. 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 biamping 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 recommendation for selecting the proper crossover frequencies. The throughput DIN connector allows easy access to Channels 1-4 inputs for routing to additional amplifiers in your system by using the optional AC202 (DIN to female RCA) or AC207 (DIN to male RCA) adapter. DIN throughput connections: pin 1 ch 4 pin 2 audio signal ground pin 3 ch 2 pin 4 ch 3 pin 5 ch 1 pin 6 not used pin 7 not used pin 8 remote power control system configurations All a/d/s/ PowerPlatesTM provide extensive features which make a variety of system configurations possible. It is not feasible to cover all of the possibilities within the few pages of this manual. There are a few system configurations, however, which are extremely popular when used alone or as a “building block” of a larger more elaborate system. Please review systems 1 through 4 described below for suggestions on how to configure the most popular combinations. Larger systems may be built from a combination of the simpler building blocks as shown in systems 5 and 6. button is disengaged control is non-operational button is engaged control is operational System 1 – PQ40 used in 4-channel mode with front and rear full range speakers. System 2 – PQ40 used in 3-channel mode with high-pass main speakers and low-pass subwoofer. Note: Although shown as 2-channel, the source unit may be either 2 or 4-channel depending on the setting of the 2/4 channel switch. System 3 – PQ40 used in 4-channel mode with 2 channels high-pass, 2 channels low-pass or bandpass. Depending on the crossover frequency chosen, this configuration may be used for satellite/subwoofer operation or to bi-amp a midrange/tweeter combination as shown. Note: Although shown as 2-channel, the source unit may be either 2 or 4-channel depending on the setting of the 2/4 channel switch. digital crossover frequency display To facilitate quicker system tuning, we have incorporated a digital display that shows the crossover frequency for each crossover s...
