Sound system outdoors this time discuss about the techniques BTL.Bridge Transformer Less (BTL) in the power amplifier is a combining two into one amplifier to both amplifier actively working with each other opposites.Could be use inverting op-amp circuit or often or commonly used is combining it with a 10k - 40k resistors ( R - BTL ) . If your amplifier is very powerful then the generated power can be up to 4 times as much ( 2x current results , voltage power 2x = 4x ) .
Then.. where we would put a resistor 's ( R - BTL ) ?
We will put ( R - BTL ) at the foot of R33K (which is on track speakers) in power ch 1 and others to power ch2 with R33 .
Please see the next picture , the values here in accordance with the value of the component that is in the power amplifier circuit .
The input to the power ch 2 does not use or you can connect it to ground .
Usually R - BTL same / close to the value of R - gain , here 33K
What is the power supply that we need can we adjust , if using a series of 2 x 150W , try using a transformer that is capable of delivering a power of 600watt -10 amperes , but better to use a second power supply ( power supply ) , 2 x 2 x 300watt or transformer 5ampere . This is the most minimal transformer , apply power to test our strength and power Bridge is usually used to test large speakers( 18inch ) in a sound system outdoors, and no more than 2 units of the speakers alone.
