low pass is for subs only it tells the amp to play low frequency only dont run subs on high pass or off

What should I do to install a low pass filter if my amp doesnt have one?
A: Installing a low pass filter is only required if the frequency are not there or to eliminate the low frequency, If it is an audio amplifier you never will need low frequency since your mine hears cannot hear those frequency.
Will loading effect occur in cascading of LR low pass and LR high pass filter?
Yes, you have to use an op-amp buffer to prevent the loading effect.
How do you set your qsc amp for your club subwoofers?
set the dip switches on the back to low pass filter and put limiter on to save overdriving
What should the low pass filter be set to?
If it is a subwoofer amp then set it at about 80 hz.
What is an Op amp Circuit?
op-amp rolloff is an inherent low pass filter built into op-amp chips. Because op-amps have such a high gain, they are prone to breaking into high-frequency oscillation; therefore limiting the gain by frequency with a built in low pass filter helps stop this from happening. Imagine a super small signal is leaking into an op amp, because of the high gain it becomes no longer negligible and we have a high frequency signal when the output should be zero. The low pass filter lowers the gain at these High frequencies. Now, this will naturally create gain limits when designing circuits, forcing an upper bandwidth. This is adjusted for by lowering the gain you design into your circuit for the bandwidth you are dealing with (which is one of many reasons we build multi-stage amplifiers)

What does decade means in opamp?
In the op-amp decade means falling down . it is used when we talk about active filter whether it is band pass or low pass or whatever the gain after that (undesired frequency) how falling down is measured in decade for example -20 db decade.
How-do i ground my amp?
amp by pass harness
How do you remove front door speakers of 1999 eclipse?
You have to remove the door panel. After you will see the speaker which sits in 4 screws. Remove the screws disconnect the speaker and in the reverse order for your new speaker. Keep in mind, whatever new speakers you get, the stock amp on this vehicle has a low pass filter to the door speakers (and a high pass filter to the dash) so they won't deliver any highs.
Where is the 20 amp inline fuse for the fuel filter in a 1988 firebird?
A fuel filter does not have a fuse.
To design a second order low pass filter?
Although there are many filter types and ways to implement them, here's an active low-pass filter that's greatly simplified if R1=R2 and the op amp stage is a unity gain follower (RB=short and RA=open). Designing a 2-pole Butterworth filter requires just a few steps. 1. Choose a cutoff frequency fo (Hz). As an example, select fo=10 kHz to reduce a noise signal at 50 kHz and pass your desired signals below 5 kHz. 2. Pick a convenient cap value C2 between 100pF and 0.1 uF. Suppose you've got plenty of 1000pF caps in stock, select this value for C2. 3. Make C1 = 2 x C2 C1 = 2 · C2 = 2000pF 4. Calculate R1 = R2 = 0.707 / (2 · π · fo · C2) R1 = R2 = 0.707 / (2 · π · 10kHz · 1000pF) = 11.2 K ohms ......Rajiv......(scet)
Is the low voltage increase the amp?
Yes
