Riaa characteristic
http://www.soundfountain.com/amb/ttcartridge.html WebbA wide frequency characteristic and high magnetic noise exclusion capability are acquired by 78% permalloy L type core, and balanced winding structure. There is 2 sets of 10-ohm winding in a primary of the transformer. Primary impedance will be set to 40 ohms if 2 sets of winding is connected in series.

Webb8 feb. 2009 · Here are the RIAA EQ curves as applied to constant amplitude recording and playback: Curve A is for recording, curve B for playback by a constant amplitude (crystal or ceramic) cartridge. Note that this curve looks a LOT different from all the other RIAA curves that you've seen published and that there is much less level deviation from flat.

WebbThe RIAA equalization is split into two halves. The 2130 Hz pole is created by C3 (330pF) and the combination of R4/R5 and the output impedance of the first stage. This should solve the high frequency overload problem in the second stage. WebbGy at low frequency is boosted by the RIAA characteristic and deter. 3d a8 follows, ay = Rice + Rios Rage + Fas (at ow frequency) {is the frequency where Gy decreases 348, 1 Bri Rion ‘This functions to eliminate supply voltage ripple. Cross Cros, Rios, and Rios determine the frequency characteristic of the equlizer amplifier.
WebbImplementing this characteristic is not especially difficult, but is more involved than a simple amplifier. Practically every 20th century hi-fi preamplifier, integrated amplifier and receiver featured a built-in phono preamplifier with the RIAA characteristic. Webb23 jan. 2003 · I think that using the 2SK170 (I have the 2SK240 for the RIAA) should probably require an adaption of the R1, R2, R4 resistors in the input section to get the same wide bandwidth result. Distortion: at 6 dB output, -100 dB second, -120 dB third, no higher harmonics. This is thanks to EUVELs nice sim settings I can assure you.
