Does crossover go after amplifier?

Does crossover go after amplifier?

Passive crossovers go between the amplifier and the drivers (tweeters, speakers, and subs). A passive crossover circuit is built with coils, capacitors, and resisters beefy enough to handle the high output power of most amplifiers. An active, or electronic crossover goes between the receiver and the amp.

What is an amplifier crossover?

A crossover is an electronics device that takes a single input signal and creates two or three output signals consisting of separated bands of high-, mid-, and low-range frequencies. The different bands of frequencies feed the different speakers, or “drivers,” in a sound system: tweeters, woofers, and subwoofers.

Do I need a crossover if my amp has one?

While you can typically get by just fine without a crossover in a situation where you’re just using a single amplifier, more complicated builds can really benefit from an active crossover. For instance, a 3-way crossover is a component that you actually wire between your head unit and multiple amplifiers.

Is a crossover necessary in car audio?

Why Do You Need A Crossover? Every audio system, including the one in your car, needs a crossover to direct sound to the correct driver. Tweeters, woofers and subs should get high, mid and low frequencies respectively. Every full-range speaker has a crossover network inside.

Does a subwoofer need a crossover?

While there are internal passive crossovers inside some PA speakers, you’ll need an active crossover to split signal to your subwoofer and mains. Most powered subwoofers include active crossovers, but they tend to be simple and feature a fixed crossover point (usually around 100Hz).

How do you avoid crossover distortion?

The problem of Crossover Distortion can be reduced considerably by applying a slight forward base bias voltage (same idea as seen in the Transistor tutorial) to the bases of the two transistors via the center-tap of the input transformer, thus the transistors are no longer biased at the zero cut-off point but instead …

Is a DSP the same as a crossover?

A DSP does the same thing and more, it usually adds many features like time alignment and EQ to further customize the sound, plus the crossover frequencies and slopes are variable, so you can adjust them to fit your environment, so you are no longer stuck with the passives that may or may not be ideal for your car.

What is the best setting for an equalizer?

20 Hz – 60 Hz: Super low frequencies on the EQ. Only sub-bass and kick drums reproduce these frequencies and you need a subwoofer to hear them, or a good pair of headphones. 60 Hz to 200 Hz: Low frequencies requiring a bass or lower drums to be reproduced. 3,000 Hz – 8,000 Hz: Upper mid-range frequencies.

What should subwoofer dB be set at?

Most people find that 70 or 75 dB on your SPL meter at your listening seat is a comfortable playback level. While 85 dB SPL is often used for THX movie theaters, that level is simply too loud for most listeners with test signals in the confines of an average-sized home theater or living room.

How does an active crossover work in an amp?

Active crossovers work with a line-level (RCA) signal either before an amp’s RCA inputs (in add-on external crossovers you can buy) or inside the amp. The signal output of an electronic crossover has to be amplified, unlike speaker (passive) crossovers that you connect between an amp and speakers.

How to set crossover frequency for car audio system?

Wherever the crossover controls are, try setting the lowpass crossover for the subwoofer and the highpass crossover for the mid/tweeter amp somewhere between 70 and 90Hz. If the crossover slopes can be adjusted, set both the low- and high-pass slopes to the same setting, probably 12 or 24dB per octave. Again, these are just starting points.

What are the different types of passive crossovers?

A passive crossover doesn’t need to get hooked up to a power source to work. There are two kinds of passive crossovers: component crossovers that connect between the amplifier and speakers, and in-line crossovers that fit in between the receiver and the amp. Passive component crossovers step into the signal path after the amplifier.

Do you need a crossover for an outboard amplifier?

If you plan on expanding your system in the future, it’s wisest to go with a separate outboard crossover, instead of relying on the ones built into your receiver and amplifier. While these built-in crossovers work well, they don’t offer the total system control of an outboard unit.
