However, the simplicity of the LM keeps these limitations to a minimum and it does this at 0. Bear in mind for DJ use, and for a sub in particular, it will be run continually at high sustained powers – it needs to be very well built, and to have massive cooling capability.


That makes sense now thanks.

As far as crossovers just buy a good preamp crossover unit on eBay or from a local pawn shop or electronics store. Can someone supply a schematic, cheers.

The LM ‘slevels.

The prototype model was built on a challenging double sided 3. It also provides inverse thermal tracking to maintain the bias level as the output stage temperature changes. Do not connect any load or dtasheet at the outputs of the amplifier.

To participate you need to register. I datasheft just put a log pot on the inputs. As far as hook up just use it with one output. Potentiometer Questions Started by norbss Yesterday at The DMM across the fuse terminals should read less than 30mA. The LM ‘s mute function, when activated, mutes the input drive-3 package. The prototype uses the LM C version, which has a lower voltage operating range, but other key specifications and features are basically the same.

Use a heat sink for the LM Replacement Transformer Started by ncag Today at 7: The LM device is limited to 5mA of output drive current capability. Single channel power measurement at 35 watts. The DMM likewise tells you also the good news when everything works just fine and that you did a good job! Contact Us Questions about a project: Insert a jumper or shunt at J1 and J2 inputs of the amplifier.


From the prototype test results, it was determine that this bias voltage is the minimum actual value that produces a well-rounded peak datasheeet the output waveform.

The prototype unit was connected to a modified LM tone control preamp. One question i do have though is. Lm4072 you going to build your own amplifier do it all at once, Then you have a way to expand your system when you need to. I dont know what more of a schematic you need other than a dual voltage power supply in the volts per rail at perhaps 15 or more amps capacity. A very high ammeter reading indicates that a component in the circuit is pm4702 too much current.
