What are the advantages of active over passive guitar pickups?

*actives have less hum which to an unexperienced player they wont hear it *active pickups are easier to swap, unplug the pickup, put the other in sort of like a video game controller... no wire soldering skills required. *there are 100s of passive pickups and only few actives pros use *passive pickups are cheaper *passive require no batteries like actives *passive pickups are cheaper to swap out (less work required is the reason) *passive pickups don't sound as sterile as say EMG pickups , blackouts are more real sounding though. to reduce hum look into pickup covers and copper shielding tape


Do you have to have a battery for the GSR200 ibanez bass?

no but the phat bass boost won't work. that is the active part. the pickups are passive and don't need a battery


Will an unpowered subwoofer work when plugged into an amplifier?

A passive sub-woofer does work when plugged in to an amplifier. In an active sub-woofer ("powered") the amplifier is built in.


What amps have two inputs?

I Have A Crate Bxr 80 And It Has Two Imputs One For Active(battery powered) Guitars And One For Passive(non-battery powered). Some Fender Amps Have Two Inputs The Work For Any Guitar But There Not Cheap.


How does the Fender S-1 switching system work?

If you have a guitar or bass with 2 single coil pickups, when they are both switched on they are parallel. The S-1 switch, or any other DPDT switch, changes this to series. This way your 2 single coil pickups will work together as 1 humbucker, creating a higher output and a warmer tone.

Will the active 3D glasses work with passive 3D tv We have an LG passive 3D TV and we need extra ones My friend has an active 3D TV though so I was wondering if I can just borrow his glasses.?

Active 3d glasses will not work with passive 3d TV. Active glasses use shutter 3D technology that requires a power source to power the lenses in the glasses. Passive glasses don't have electronics or batteries. Hence, they are lighter and more comfortable. Active and passive TV work using completely different technology and thus active glasses cannot work on passive TV.


Is this sentence written in a passive voice You can succeed if you set goals and work hard.?

No. Every verb in the sentence given is in the active, not the passive, voice


What is the main difference between active trasport and passive transport?

Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient. Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)


Difference between active listeners and passive listeners?

An active system has amplifiers and electronic crossover built in to the cabinet. A passive system has just the speakers and possibly a passive crossover (made up of capacitors and inductors) inside the cabinet. A passive system requires external amplifier(s) to work.


What is the Difference between active filters and passive filters?

Active transducers are those which require electric current (a source of energy) for working, while passive transducers are those which does not need an external source. Passive transducers directly produce electric signals without an external energy source.


Are active 3D glasses better than the passive 3D glasses because they have battery and are more expensive that active glasses seem to be more sophisticated and reliable?

Active 3D glasses are far better than passive glasses when used with an active 3D television. Similarly, passive 3D glasses work well with passive televisions. Active glasses have been criticized for their weight in the past. Later glasses are lighter than many passive glasses, have a battery life of over one hundred hours and are proving to be exceptionally reliable.

Diffrentiate between active heatsink and passive heatsink?

In a active heatsink system you have both a heatsink and a fan thus for the most part an active heatsink cools better with one exception. Should the fan fail the active heatsink will quickly overheat. Passive heatsinks relay on transferring heat without the aid of a fan. The advantage here is that a passive heatsink is fail proof and uses 0 electricity, however passive heatsinks don't typical cool as well. Passive heatsinks work great for supporting chips and RAM cooling. They are also found in servers because of the no fail aspect. EnzoTech produces some passive heatsinks you can read a bit more about them here: http://electricalninja.com/
