Other one unit of graphic EQ. five bands. The basic difference with the other circuits is, that I use instead of IC, transistor and the power supply, go up in +/- 24V DC, ensuring low distortion and bigger margins of overloading. With switch S1, we can.... -
The EQ-2 it is a circuit of graphic equalizer 6 band of regulation. Each band is regulated from the potesometers RV1-6, that are, for better optical indicate of regulations, Fader. This does not mean that we cannot him replace with simply potesometer. In the.... -
The Boss GE-7 Equalizer pedal adjusts the harmonic contents of an instrument in 7 separate bands ranging from 100Hz to 6. 4kHz, with a boost/cut 15dB per band. The additional Level control knob helps you to set a different volume for normal and effect sound.... -
This discussion continues on from the audio tone control topic, which introduced both passive and active tone controls. The follow on topics might be a 2-Band Active Tone Control, or the 3-Band Active Tone Control. An audio equalizer is used to adjust the.... -
This topic covers a resonant equalizer which is a different style circuit than the common audio equalizer, although both produce the same result. The difference here is that the frequency response of both the high and low frequency equalizer covered on the.... -
An equalizer is a device that allows you to adjust the gains of individual frequencies. You may want to lower bass, so on an equalizer, you would go to the frequency range of bass, which may be around 500Hz and turn down the volume. If you want to increase.... -
The music equalizer display schematic is not a very difficult one to build. I managed to fit it all on a nice little breadboard. You will need all the parts listed out on the previous page to put it together. It is quite wire-intensive so make sure you have.... -
This is about as close as you can get to a real vintage Pultec EQP-1a. Built from the original Pulse Techniques Pultec schematic with the layout designed around modern replacement parts (filter caps and trannys); and utilizing best practices regarding lead.... -
The GS1674 is a high-speed BiCMOS integrated circuit designed to equalize and restore signals received over 75ohm coaxial cable. The device is optimized for performance at 270Mb/s and 1. 485Gb/s, and features DC restoration to compensate for the DC content.... -
