Organist, always had the most critical and reliable ears. He was an ingenious design engineer, a strong contributor, who inspired and challenged many of us on our HP and unofficial design projects. Russ retired after over 40 years in R&D for HP/Agilent and now lives with his wife in a remote mountain valley, in a genuine log cabin, amongst pear, plum and walnut trees, berry bushes, chicken and deer, the sounds of a large creek, and the pine and fir trees that climb up the slopes. He died peacefully in his log cabin on December 6, 2010. 4 - Delay correctionA first order allpass filter section with flat amplituderesponse but phase shift that changes from 0 degrees to -180 degrees, or -180degrees to -360 degrees, is often used to correct phase response differencesbetween drivers. Multiple sections may delay the tweeter output and compensatefor the driver being mounted forward of the midrange. Active crossover circuitsthat do not include phase correction circuitry are only marginally useable. (allpass.gif,allpass2.gif, models.htm#E,38xo_eq1.gif) Top 5 - Shelving lowpassThis type of circuit is useful to bring up the lowfrequency response in order to compensate for the high frequency boost fromfront panel edge diffraction. It can also serve to equalize the low frequencyroll-off from an open baffle speaker. (shlv-lpf.gif,38xo_eq1.gif) TopA passive RC version of the shelving lowpass is shownbelow.6 - Shelving highpassA circuit used to boost high frequencies or to smooth thetransition between a floor mounted woofer and a free standing midrange. (shlv-hpf.gif,38xo_eq1.gif, models.htm#F) TopA passive RC version of the shelving highpass is shownbelow. 7 - Notch filterNotch filters are used to introduce dips in the frequencyresponse in order to cancel driver or room resonances. The three circuits abovehave the same response. A) is difficult to realize because of the largeinductor. B) is used to remove the peak in In the formulasabove. LR2 LR4 LR6 LR8 LR10 Q0 of stage 1 0.5 0.71 0.5 0.54 0.5 Q0 of stage 2 0.71 1.0 1.34 0.62 Q0 of stage 3 1.0 0.54 1.62 Q0 of stage 4 1.34 0.62 Q0 of stage 5 1.62 dB/octave slope 12 24 36 48 60 Crossover filters of higher order than LR4 are probablynot useful, because of an increasing peak in group delay around f0. Top 3 - 24 dB/oct Linkwitz-Riley crossoverThe 24 dB/oct LR4 crossover filter providesoutputs which are 360 degrees offset in phase at all frequencies. At thetransition frequency Fp the response is 6 dB down. The electrical network willonly give the targeted exact acoustic filter response, if the drivers are flatand have wide overlap. This is seldom the case. The steep filter slopes make thecombined acoustic response less sensitive to magnitude errors in the driverresponses, but phase shift errors usually have to be corrected with anadditional allpass network. (xo12-24b.gif,38xo_eq1.gif, models.htm#E) Top Russ Riley and Siegfried Linkwitz, September 2006, Douglas City, CA In the sixties, early seventies, I worked with Russ Riley at Hewlett-Packard's Palo Alto R&D laboratory for the development of RF and Microwave test equipment. Like many other engineers we had "G-Jobs", building such things as electronic ignitions for our VW bugs and vans, FM receivers, phase-locked pulse width FM demodulators, short-wave receivers, audio pre- and power amplifiers, third octave audio analyzers, headphone equalizers, and of course, loudspeakers. After measuring the acoustic and electrical responses of commercial speakers we equalized them and tried to understand why they were designed with strange looking driver layouts, used large baffles, were stuffed with a variety of internal damping materials and used various box stiffening and damping techniques. Eventually we completely redesigned them and built our own speakers. Russ and his wife, Vicky, an accomplished

Kirchhoff-EQ uses a technique called “Double-Double” to make precision of internal processing reach 117 bits! This is the first equalizer in the world to reach such precision. You can switch between 64-bits and 117-bits at any time. It satisfies the most demanding ears.* Linear-phase mode always uses 64-bits as it is an FIR(finite impulse response) filter, and does not support 117-bits.Filter Types15 Unique Filter Typeslow pass, high pass, band pass: continuously variable from 0 dB/oct to 96 dB/oct;bell, notch: continuously variable from 12 dB/oct to 96 dB/oct;low shelf, high shelf, tilt shelf: continuously variable from 6 dB/oct to 96 dB/oct;flat tilt and flat top;sword: has sharper slope than bell, specifically designed to “dig” out resonances.brickwall low pass, brickwall high pass, allpass low and allpass high.Continuously variable slopes FiltersThe slope of most filter types can be continuously changed from 0 dB/oct, 6 dB/oct or 12 dB/oct up to 96 dB/oct.

Creates a less regular delay period, and so more complex sound.Delay TypesFake stereo - Pseudo-stereo delay effect based on a single, monophonic delay line with summed L/R signal and 2 different tap points for L & R delay.True stereo - Echoes are stereo. The Left and Right channels are separately delayed. Offset controls pre-delays for the Left and Right channels to create left-right bouncing / panning effects. Feedback is likewise per channel, so the left and right channels stereo content is maintained.Ping pong - Echoes are mixed stereo, with the left and right channels alternately flipped on each delay loop to create the left-right bouncing effect. If you are using a stereo source you will hear the channels swap or bounce on each echo.

Full scale, -6db ishalf of full scale and +6dB would be twice full scale. Further reading: delay / delay lineA delay line (sometimes simply delay) is a device which delays asignal (such as an audio signal) by a fixed or variable time. At least inprinciple, a delay line reproduces (outputs) its input acurately at some latertime. Delay lines may have a fixed delay time, or the delay time may be varied(either by a user control, or using modulation such as a low frequencyoscillator). A delay line may be tapped at multiple points to yield multipleoutputs which are each a version of the input delayed by a different amount.dissonanceThe musical concept of two or more notes played simultaneously soundingdispleasing. For example, a semitone is said to be more dissonant than a fifth.The opposite of dissonance is consonance. See also consonance.distortionAn effect where the quality of an audio signal is modified or degraded, itis commonly achieved by overdriving an electrical circuit beyond its normalrange. There are as many types of distortion as there are circuits whichproduce it. Distortion always adds additional harmonics, which can make soundsmore harsh and raspy. Some kinds of distortion, like tape saturation and tube amplifier distortion, are considered more "musical" than others, as they add subtle levels of additional harmonics, or interact in complex relationswith the amplitude of the source signal. More extreme distortion effects are commonly used with electric guitar.doppler effect (dopplershift)The doppler effect happens when the pitch of moving sounds is perceived as a shifting pitch

Instructions on how you set your scanner up, that would be super useful. #7 Where can I find the delay settings? Also, I am monitoring about ~20 frequencies with different modulation types (P25 & FM). Southern New Hampshire is where I am scanning from as well. I’m on the road at the moment and not in front of my PC but in the top of the FMP24 scan list file it should give some examples. It should show the delay example in there. It may be listed in the notes.txt also, just open that and use the search feature and search scanlist. If you can’t find it, let me know and I’ll post mine when I get home. #8 Where can I find the delay settings? top of the FMP24 scan list file it should give some examples.
