Category: Inside Circuits Views: 609 Rank: 10 The schematic shown, does no need any power supply because is a simple low frequency passive filter. It could be usefull if you want to drive an extra subwoofer from your stereo system.  The circuit filters the frequency ranges above the 150Hz. The schematic is calculated to work with a 50 watts audio amplifier, but can be used with higher powers as well. The frequency can be adjusted with 2k2 potentiometer from 50 Hz to 160 Hz.
Related circuits Programmable bandpass using twin-t bridge The circuit gives a programmable bandpass where both the cut-over frequency and the gain, A, are controlled independently. In the twin-T bridge the resistors R and R/2 are replaced by two double FETs, 430, the channel resistance of the first one in the series, the channel resistances of the... Inrush Current Limiter Circuit Q1 is an npn Darlington and Q2 is a prip Darlington. MOV1 is a metal-oxide varistor and R8 is an thermistor for limiting inrush current. This circuit limits ac line current to a load. When a predetermined interval has passed, RY1 shorts out thermistor or resistance RB. R4 can be 150 kQ if R9 is... The circuit is basically a 555 astable circuit that divides two LEDs, LEDl and LED2. LED2 is switched on when the output of Ul is high, and LEDl is activated when its output is low. When Ul oscillates, LEDl and LED2 switch on alternately as the output of Ul switches from state to state.... A tricolor LED, acts as the visual indicator of the voltage level. The voltage to be measured is connected to the two comparators in parallel. The first 20-KO trimmer defines a voltage between ±5 V and this becomes the full-scale value of the reference voltage. The second trimmer is a fine... Engine Block Heater Minder Circuit If you live in the frozen north, knowing your engine-block heater is working is a comfort. This device will let you know if yours is okay. Plug in PL1 to your power outlet. NE1 should light. Then, plug in the block heater. Depressing SI should cause the indicator to get brighter. Oscilloscope-counter-preamplifier The circuit will provide a 20 ±0.1 dB voltage gain from 500 kHz to 50 MHz. The low-frequency response of the amplifier can be extended by increasing the value of the 0.05-JLF capacitor connected in series with the input terminal. This circuit will yield an input-noise level of approximately 10... Ir-Controlled Soldering Station An IR-sensitive phototransistor is used to sense soldering-iron temperature. The phototransistor must see t The circuit, a general-purpose system with many uses, vocalizes 59 allophones contained in the speech processor. After filtering and amplification, its pulse-code-modulated output can drive an 8-!l speaker. The processor"s address pins, Al to A6, define 64 speech-entry points. Closing the test...

Nice Schematic.
I think it must be between Pre and Poweramp right?

To Jezzus...you should know the answer, while you are trying to build a circuit for low power signal part..it means the 10 K Potentiometer is for the voulme level setting, and you dont need any resistor with specal high power. the most output devices provides an output with max 0,1 wat or lower.

What components would you have to change to increase frequency cutoff range to around 400hz?

Where to connect the circuit. i build the circuit and i connect before my sub woofer and also try to connect before my power amplifier input line but the circuit not working if i connect any 10k ,2k2 volume control(preset) please reply i have stereo amp ,sub-woofers 2*240w i want real bass effect

could any one can tell more details about this circuit were like this circut to connect amp and capacitor in volts so im a beginer to electronics.
asbn wrote on Dec 13, 2009
sorry.Rewrite!. Could anyone can tell more details about this circuit were like we have to connect this circuit and how this circuit works, role of each components etc

You would wire this up after you sub PRE-amp but before your sub POWER amp (ie between the two).
most setups this will be running between the source unit and the poweramp/subwoofer. In most cases this wire has RCA connections either side. Do NOT wire this after your poweramp.

Best circuits with punched bass.Modified circuit with single op amp with good LF tonal response available.
s.shahhul hameed wrote on Jan 15, 2010
you should remember that frequency is inversly proportional to passive components lke resistors &capasitors.Use the formula for cutoff freq calculations f=159.2/rc .substitude the resistence &capacitance value directly.
