Most of the good subs are powered, have their own amplifiers so you do not need a amp for usb. A typical HT setting does not use passive subs.

it's active and is able to power HI level in speakers. You may need an RCA Y adapter since the line in consists of red and white RCA jacks. It is a good speaker though.

Yes, both the base unit and the cordless handset are amplified. Hope this helps.

Mono. The left and right outputs are passive. There is one output for the subwoofer on the rear or the amp. Read the directions.

I think white is neutral and the difference between red & yellow is the type of sound you want to emit. Pick one & disregard the other.

No, they are passive, not amplified speakers. They have banana plugs on the back of each speaker for connecting to a home theater type amplifier or audio power amplifier.

One is plenty loud. You'd only need two if you wanted the sound in stereo. I'm not sure if it will power a passive speaker.

No, this is an active sound bar because it has a built in amplifier. A passive sound bar will be just the speakers in a bar and it will require an external amplifier to deliver sound. This type are usually installed as a Center Channel.

NO. I think some are having trouble understanding the concept. The sound will be reduced by the same amount with the unit turned on or off. That's passive unlike active like noise-cancelling muffs like Bose. When turned on, it will amplify sound below 82db. (A busy street is more than 82db) Anything below 82db, like a range instructor's commands, will be amplified and you can turn the volume all the way up and leave it their. When a sound is above the cutoff of 82db, like a gunshot, the mics will shut off and go back into passive mode until the sound drops below the cutoff, and then go back to amplified mode. The mics will never amplify a sound greater than the cutoff of 82db. Hope this helps. NO. I think some are having trouble understanding the concept.

It is not offensive. It is loud enough to notice and only beeps once. I like it

It only amplifies the ringer. It is loud enough to enable those who are hard of hearing to answer their phone.

No noises or sizzle just amplified. I have had noises when the battery is low. Works good for me. Hope this helped.

Active.You do NOT need an amplifier.The amplifier is built into the speakers and each speaker needs power and each comes with its own power cordI love the clean sound and works well for near field monitoring.I am NOT a professional in music.

All audio files are mp3 and they play in a loop. So your greeting if loaded in a single file will take some time to come around.
