What is the voltage gain of a transistor amplifier that has an output of 5 rms and an input of 250 mV rms?
The voltage gain (Av) of a transistor amplifier can be calculated using the formula ( Av = \frac{V_{out}}{V_{in}} ). In this case, the output voltage is 5 V rms and the input voltage is 250 mV rms (which is 0.25 V). Therefore, the voltage gain is ( Av = \frac{5}{0.25} = 20 ). This means the amplifier has a voltage gain of 20.
How do you match amplifier and speaker watts?
Short Answer: Try to get speakers with an RMS wattage rating roughly equal to the RMS wattage rating of the amplifier (per channel). Further Information: If you amplifier puts out 75 W RMS per channel, get a speaker that can handle 75 W RMS. If you get a speaker that handles 150 W RMS per channel, you will find that the amplifier doesn't have the power to make it sound as good as it could / should. Also, lower frequencies (where the amplifiers wattage rating is put to test) could burn out your amplifier. The opposite is also true. If the speaker can only handle 25 W RMS and you hook it up to a 100W RMS amp the amp might send so much current through the speaker coil that the coil wires heat up, burn off their coating and short together. This, in my opinion, is much less likely to happen though. NOTE: An amplifier doesn't put out its rated wattage all the time. The amount of wattage dissipated by the speaker varies directly and greatly with the music. A flute solo for instance being played with a huge 1000 W RMS amplifier might just put out 20 W RMS during the solo. But when the big organ kicks in jumps to over 900 W RMS.
What and where is the best 1 RMS or PMPO?
rms is the best because 1 RMS = 100 PMPO
Can you run speakers with an amplifier that has a bigger rms rating than the speakers rms rating For example run an 80 watt rms speakers with a 120 watt rms amplifier?
Yes you can. Contrary to popular belief, an amplifier rated with a higher output than the speaker rating rarely damage the speakers. If the amplifier overdrives the speakers, the sound quality will be dramatically affected. Most listeners will turn the level down to reduce the distortion being heard. The amplifier's power rating is the maximum power that it can produce and it does not mean the output power will be at that level. On the other hand, an amplifier that is overloaded will deliver distorted signals to the speakers. At high power levels, the distortion can be damaging to the speakers in a way that simply over driving a speaker is not. Therefore, it is as safe to use an overpowered amplifier with speakers as it is an amplifier that is rated at the same power or even lower power than the speakers.
What amplifier should I get for my 4 Pioneer TS-A1680R speakers -- 220 watts peak and 50 watts RMS?
Scroll down to related links and read "Why there is no such thing as 'RMS watts' or 'watts RMS' and never has been".
What speakers match a 300 watt 4 channel amplifier?
The ratings for the speakers will depend upon what '300 watts' means. If the amplifier develops 300 watts RMS total across 4 channels, this would indicate 75 watts RMS per channel. Speakers rated at 100 watts should suffice for this amplifier.
Best match of amplifier with speakers?
I always try to match an amplifier or receiver that is rated within the following range: from .8 times to 1.5 times the RMS rating of the speakers. The impedance of the speakers should not be rated below 5 ohms unless the amplifier/receiver is conservatively rated as 4 ohm stable.
If you have two 1400 watt subwoofers that have a 700 watt RMS should you get an amplifier that has the watts of both of the subwoofers together 2800 or should you get an amplifier with only 1400 watts?
get the 2800
What size amplifier will power 3 JL audio 8w7's?
1000 watts rms should be plenty
What power of amplifier will you need to for 1000 watt subwoofers?
Find out what the rms is for that sub woofer,if it'1000 then find out what the max is,then you could go between the rms power and the max power to get the right amount of watts.
How many watts is alpine v12 mrv-f505 amplifier?
The Alpine v12 MRV-F505 amplifier puts out up to 200 watts of RMS power at 4 Ohms and using 12 volts. At 14 volts, it puts out up to 400 watts of RMS power with a bridged 4 Ohms ratio.
What kind of amp do you need for one 10 inch Alpine Type X subwoofer?
Alpine offered up until last year the PDX-1000 wich is a 1000 Watts RMS amplifier designed with the type X subwoofer series in mind. Now the best match would be the PDX-M12. Set the amplifier gain carefully as this amplifier is a bit strong for this subwoofer.
