It's entirely possible to use four 70W speakers with a 150W amplifier but the method will depend on the speakers and the amplifier specification. We will assume that the amplifier will deliver up to 150W per channel, so two speakers will be used on each channel. If the amplifier is rated to drive a 4 ohm load, then two 8 ohm speakers can be wired in parallel and connected. In this instance, take care NOT to drive the amplifier too hard. It will overdrive the speakers at about the same time that it will begin to show a distorted output. This is a condition that can easily damage speakers so be very conservative with the volume control. If the speakers are 4 ohm speakers, they can be wired in series to provide a total impedance of 8 ohms. If the amplifier is rated to deliver 150W into 4 ohms, then the total power to the speakers will be lower than to a single speaker. The benefit is that no speaker can be over-driven and there is a good amount of headroom for safety.
An amplifier head is needed to drive a cabinet of speakers to make up an amplification rig for playing bass guitar through. Heads can be bought separately from your local music shop or on-line supplier.
Amplifiers are rated to operate within a range of impedances. Typically, a domestic amplifier will drive a minimum impedance of 8 Ohms or 4 Ohms. Using speakers that have an impedance lower than the amplifier rating is likely to increase distortion and can damage the outputs of the amplifier if the levels are too high. Using speakers that are significantly higher than the minimum rating will not cause damage to either the amplifier or speakers but it will reduce the power that is delivered to the speakers. In most domestic systems, this limitation of the power output is not likely to be an issue. Any amplifier rated to drive into 4 Ohms will work well with speakers of between 4 and 8 Ohms. An amplifier with an 8 Ohm rating should be used only with speakers of 8 Ohms or higher.
impedeance matching methiod is used to drive a speaker by any amplifier.
Depends on what your definition of "receiver" is, but most of the time - to the amplifier. Consider: if the receiver is some form of a device that receives some signal, and then decodes it to audio, then the receiver will hook into the amplifier, which in turn will drive the speakers (so the speakers go to the amplifier) if, on the other hand, the receiver is a part of a wireless connection between the amplifier and speaker, then it really serves the role of a cable, so in essence you're again connecting the speakers to an amplifier (only using the receiver as an intermediary) You would have to specify your case.
Maybe. If you need to drive passive speakers, you will need an amplifier. If you have powered speakers, you might not be able to control the volume of the signal.
Depends on the amp and type of speakers brand and ratings would be nice info u also need to look at ohms of the amp and the speakers
A: No speakers are not at risk. what it maybe a risk is the amplifier if it try to drive 180 watts load. but as long as you keep the level at 10 watts output it should work fine
You need a 5.1 Decoder and an amplifier to drive the speakers, most companies build these items into their RECEIVERS which comes with the switching you heed with most home theater systems.
Xenyx 802 is not a powered mixer, you need a separate amplifier with it to drive the speakers
Insert a music CD in the optical drive. A. Check the volume controls on the speaker amplifier.
Its indeed an amp with all high qualities, Can drive any moderate to current hungry speakers
