The Q (bandwidth) control for the high boost bell curve can go twice as wide as a normal Pultec and it can also do one thing I have never seen on any other Pultec or clone do. I see a lot of passive DIY designs out there and wonder if the designer has chosen xover points and slopes arbitrarily because of what looks good in the sims, or tested many variations. It is designed to be a fundamentally different EQ but incorporates the best strengths of Pultecs, choice console EQs, parametrics and graphics. But the EQ bands have to be laid out in a different way to the normal PEQ-1A to get the cut/boast on each EQ band. A graphic EQ is a set of fixed-frequency, fixed-bandwidth/Q filters set up so their frequency ranges match tidily at their half-power points, so that when they're all set to match, there are no "holes" or overlaps between the adjacent bands. I don't consider the preamp noise to be a problem in most applications as it is is at least 10 db below the surface noise of the record. Here the signal is attenuated or damped at low frequencies with the output increasing at +20dB/Decade (6dB/Octave) until the frequency reaches the cut-off point ( ƒc ) where again R = Xc. in three bands, although a fourth subsonic band could be added to allow very low frequency analysis. 3-band equalizer on each channel and 7-band graphic equalizer on the main. The GML 8200 EQ design is a good example of an EQ design that allow the Q to be varied while the amount of boost/cut remains constant. Phono Amp PSU Schematic Low-power supply for 2 and 3 tube preamps. For example, if a graphic equalizer has a fixed control at 20 Hz, a parametric equalizer can be adjusted to control frequencies at 10 Hz, 15 Hz, 20 Hz, 25 Hz, 30 Hz, and so forth.

The drums were recorded with three mics; the bass drum goes into Ableton Live and then through an EQ and gate, which then heads into the modular via audio to trigger the twin-T drum module. After the frantic soldering fest that was The Pagey Project, I figured it might be time for a nice, simple DIY wiring project. The passive filter consists of resistors in series and capacitors in parallel to closely achieve the proper component values. The equalizer pedals we recommend in this guide start at 3 bands (low mid and high), and go up to as many as 10. Here are the calculations needed for a vacuum tube RIAA phono equalizer of the RC-equalized, split passive type, for a triode with bypassed, or battery-biased, or grounded cathode: For the first section, with 75 and 3. It's a bit of a hack yet it's the only way I've managed to implement the controls as functional. Earning passive income is great but it can be tough in the beginning to see how amazing passive income is. All three bands (bass: 30hz, midrange: 650hz, treble: 5. Its called passive equalization because the frequency shaping is all done by attenuation using resistors and capacitors.
