"frequency out of range"

The audio amplifier(s) output 20hz/20khz.

The speakers reproduce 45hz-18khz.

Hi Ethan,

What you're looking for is called a "crossover". A crossover is an electronic filter for an audio or speaker circuit. In an audio circuit, a crossover is used to prevent or pass certain frequencies or a range of frequencies from passing through it. Since your sub will reproduce the bass or low frequencies, you don't want other speakers to reproduce them. A band pass filter on your door speakers will do this for you. A band pass filter passes only a range or "band" of frequencies and blocks those that are above and below the range or band of frequencies selected. Installing a band pass filter will prevent the very high & very low frequencies from getting to the door /dash speakers. Likewise, you should consider connecting a low pass filter to your subs, too. The low pass filters work a little differently from of the way band pass filters work - they only allow low frequencies to get to the sub - blocking all the other higher frequencies (your other speakers are better suited to reproduce those). Lastly, you would install a high pass filters on tweeters. Tweeters are designed to reproduce only the high frequencies - sending mid and low frequencies to them is wasting power and can cause damage to them.

You purchase the filters for specific crossover points (the block / unblocked point) as determined by the individual speakers. If a sub has a frequency response of 20Hz - 100Hz, a low pass filter of 100Hz would be ideal. Remaining filters would need to begin at 100Hz - assuming the mid-range speakers have a frequency response beginning at 100Hz. A band pass filter of 100Hz - 3KHz would fit the bill nicely if the mid-range speakers go up to 3Khz Match the high end of the band pass to the high end of the frequency response of the mid-range speakers. Next, a high pass filter at 3KHz would allow only the high frequencies to your tweeters. Basically, you want to have the entire audible range 20Hz - 20KHz covered by the speakers and have the crossover points that match the frequency response ranges of the speakers.

I hope this helps & good luck!

INPUT SIGNAL OUT OF RANGE
This OSD may appear to inform you that the signal being sent to the display is not within its frequency range. In this case, you would need to check the resolution and refresh rate you have your video card set to, and adjust to be within the range of the display

As you computer boots up, press the F8 function key several times. Then select boot up in Safe Mode - go to Control Panel - Display - Settings and change the screen resolution lower such as 1024 X 768 - Apply and Shut down computer.
Reboot the computer.

Those are the center points of its varous controls. Each one has an effect that spreads out from there. No worries.

Its as simple as it looks. Th eq butom activates the EQ control. Turning it off bypasses the EQ which is helpful for comparative listening. A lot of destruction can be done with improper equing so sometimes its a good idea to just turn it off and evaluate what the recording originally sounds like with out being tampered with. Some units have a tuneable frequency selection so you can digitally hone in on the desired frequency range that you want to bump or reduce but those are labeled frequency more often than not.

Sounds like there is an issue with the video card settings versus your monitor.

Try the following:

1.) Press F8 on boot and select VGA mode then once into the OS reset the video card options

2.) Try another monitor

3.) If you have video card, swap it out. If you have onboard graphics put a card in

Cheers...please post your results.

press the "prog" key followed by the "Trunk" key then the number "1" key.
Press the "down arrow" key until you see the initials Ed on the screen
Press the "E" key.
Enter the frequencies (including the decimals)
you must press the E key and the Prog key after each frequency, after you finish entering your frequencies, press the scan key.

If you need to clear your scanner, turn it off, press and hold down the number 2 and number 9 keys, while holding them down turn the scanner back on, "clear" should start flashing on the screen, once "clear" stops flashing you can enter the frequencies.
