Stereo power amplifier is less in the bass tones, but if a speaker that sounds just feels solid bass sound, there are several possibilities, the first one speaker cable upside down, try alternating bass and tone tests. If still, you need to use 2 power supply or attempting to use this circuit. Note this circuit works for a power amp that is less power transformer with 2 speakers (stereo). One of the speaker cable (output) should be reversed, this is okay, just a game to lighten the work phase transformer from the blow bass. We recommend that before you try this circuit, turn one speaker cable and a second test speakers with bass tones, the bass should be mutually reduce (bass-bass = 0). Next remove the driver from boknya and turn the speakers (the speaker drivers facing into the wall), the bass should grow (bass + bass = 2bass). One record store in the town of Indramayu is taking this simple way, certainly looks magnet speakers, great. The heart of this circuit using IC with 2 op-am...

The LM1036 is a DC controlled tone (bass/treble), volume and balance circuit for stereo applications in car radio, TV and audio systems. An additional control input allows loudness compensation to be simply effected. Four control inputs provide control of the bass, treble, balance and volume functions through application of DC voltages from a remote control system or, alternatively, from four potentiometers which may be biased from a zener regulated supply provided on the circuit. Circuit diagram : Bass Treble Tone Control Circuit Diagram Each tone response is defined by a single capacitor chosen to give the desired characteristic. Features: Wide supply voltage range, 9V to 16V Large volume control range, 75 dB typical Tone control, ±15 dB typical Channel separation, 75 dB typical Low distortion, 0.06% typical for an input level of 0.3 Vrms High signal to noise, 80 dB typical for an input level of 0.3 Vrms Few external components required Note: Vcc can be anything be...
