Rangkaian Audio Tone Control

Bass-treble tone control circuits
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 between 9V to 16Vand the output capacitors are 10uF/25V electrolytic.

the circuits provide some additional control over tone. They were origionally intended for use with synth modules but could be easily incorporated into most any effects circuit

Tree band aktiv tune control

A tone control circuit made with a single op-amp and having three ranges, bass, middle and treble controls.

5 Band Equalizer

BA 3812 chip 5 Band equalizer

Skema Rangkaian 5 band equalizer

In this part of the investigation in a series of 5-band Equalizer circuits with a single IC BA3812 L. a device used in the hi-fi. IC BA 3812 This is with 5-point Equalizer with all the functions integrated in one IC.

Equalizer has advantages, namely: small distortion, a small noise, dinamic local area, and is suitable for a series of hi-fi stereo. And with a wide voltage range from 3.5 volt to 16 volt. Voltage is the recommended 8 volt but according 9volt highest voltage.

The following 5 frequency channels from this series:

• 100 hz
• 300 hz
• 1 khz
• 3 khz
• 10 khz

5 band simple Equalizer

Skema Rangkaian 5 band equalizer

Following series can be used as a 5 channel Equalizer simple cheap. Working principle of this series is a series of band pass frequency with center frequency of 10 kHz, 2.5 kHz, 625 Hz, 40 Hz and 155Hz. By using potensiometer, the value of each frequency band pass possible change.

Digital Volume Control

Rangkaian Digital Volume Control

in this series can use a digital set the volume on the amplifier or tone control. although the tone control is the volume available, but we can make a volume control with a series.

to use this series, release potensiometer the tone control that serves to set the volume, and then connect the output volume of the series of digital control pin to the middle tone contrlol, input pin to the right and the left on the ground.

PIN DESCRIPTION DS1669:
