Why won't my MA120 fast act amplifier turn on?


A pre-amplifier allows a range of components with different output levels to connect to an amplifier. Usually one is used to allow a low-level magnetic phono cartridge to be used with the line-level input of an amplifier. These used to be separate units; now integrated amplifiers combine control function with amplifying low-level signals. They also provide tone, volume and balance control.

Not powering on


To troubleshoot amplifiers when it's not starting up

check the base to base voltage of driver transistors might be too high.

Make sure that the amplifier's ground wire is tightly attached. If it doesn't look too good then take it out and clean it. Use a metal brush to clean that area.

Low power may cause your amplifier not to turn on. Make use of voltmeters to check if your amplifier is getting the right amount of power for it to work. Amplifiers need 110 volts or less to function if the power coming in does not reach that it means you have la defective power cable. If the power is alright and it reaches a minimum of 110 volts, and your amplifier still doesn't turn on that means that there is a problem with its power supply. Checking an inline fuse helps you to determine the appropriate amp ratings when you troubleshoot amplifiers. This is the best way to troubleshoot amplifiers with power problems.

To troubleshoot amplifiers that seems to be on standby mode

Look into your input sensitivity. An input control allows you to match output voltage that is coming from the main unit going to the amplifier then to the stereo speaker. The amplifier shuts down if the gains are
adjusted too high. This is simply because it overheats when it is set too high thus it automatically shuts off. When you troubleshoot amplifiers and this happens you will notice that the volume gets lower even if the setting is too high. Be aware of the optimal levels of the components when you troubleshoot amplifiers.

Your speaker's electrical impedance may also contribute as to why your amplifier may be turned on but doesn't seem to work. Impedance is the amount of current which flows with a specific voltage throughout the transistors, capacitors, etc. Just see to it that your amplifier and speakers equal in impedance range when you troubleshoot amplifiers. Use the voltmeter to check the impedance range when you troubleshoot amplifiers.


Take care..

Every time i hook up my coustic car amp the radio will turn on with out the radio on


THE GOAL HEAR IS TO DETERMINE IF THE INSTALLATION IS CAUSING YOUR PROTECTION FAULT OR IS IT THE RADIO OR AMPLIFIER ITSELF HAVING INTERNAL DAMAGE. REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL POWERS UP ON ITS OWN, THEN REMOVE THE REMOTE TERMINAL COMING FROM THE RADIO. IF THE AMPLIFIER SHUTS OFF, THEN YOU MAY HAVE A SHORTED TURN-ON TRANSISTOR WITHIN THE RADIO AND IT IS OUTPUTTING THE DC NEEDED TO TURN THE AMPLIFIER ON. IF YOU REMOVE THE REMOTE TURN-ON FROM THE RADIO TO THE AMPLIFIER AND THE AMPLIFIER STAYS ON, THEN THIS POINTS TO A FAULT WITHIN THE AMPLIFIER AND IT WILL NEED TO BE SERVICED. MAKES SURE THAT THE AMPLIFIER AND RADIO GROUNDS ARE 100%. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

How many watts is it


http://www.kenwoodusa.com/UserFiles/File/Global/Consumer/Manuals/kac528.pdf

Page 7 of the manual gives you all the different configurations of this amp, and it's MAX power. FYI; Kenwood rates their amps at MAX power, not clean. Hope this helps.

Need user manual for setup of the amplifier.


It should say next to the speaker terminals what impedance of speaker the amplifier is rated for. You can drive any speaker within reason with just about any amplifier as long as you are not trying to attain loud levels. Here is a link to the service manual for your amplfier. It states in the schematic power ratings for 2,4, and 8 ohm speakers so you can assume that this amplifier is compatible with those impedance speakers. NAD is generally known for their beefy amplifier sections. http://www.scribd.com/doc/7234868/NAD-3020-Service-Manual

Car amplifiers


Generally, the 120v AC to 12v DC power supply costs more than a mains powered amplifier.

Also, many automotive amplifiers have poor speaker protection. If the amplifier fails, the speakers could be damaged. In some instances (older paper cone speakers with paper voice coil formers), the speakers could ignite.

Connecting 4 bass speakers to one amp?


If you have a 4 channel amp and 4 speakers and each speaker is connected to each of the 4 channels you are just fine.
A stereo amplifier has 2 channels, typically labeled left and right and each channel has an amplifier. A 4 channel amplifier has 4 amplifiers. With one speaker on each channel, there is one speaker on each amplifier. Audio amps are referred to as amps or amplifiers, although if they have more than one channel it would be more correct to call them something like 'multi-channel amplifier' or 'multi amplifier speaker driver'. Semantics.
