Predojaèevalec Phase Linear 4000 II - razlaga funkcij pomoè

[makra28]

Tale predojaèevalec mi že dolgo služi in mi je kar nerodno povedati, da nekaterih funkcij ne razumem najbolje, za to se obraèam na vas za pomoè.
Dokopal sem se do operating manuala in podajam opise funkcij v slikovni verziji.

Ali mi lahko kdo razumljivo razloĹľi delovanje naslednjih funkcij in njihovo soodvisnost:
Unlimit threshold (potenciometer)
Correlation threshold adjustment (potenciometer)
Low frequency calibration (potenciometer na “šraufciger”)
PK unlimit
Correlator switch
Infrasonic filter

Na prvih dveh slikah je fronta s kratkimi opisi funkcij, na naslednjih štirih pa je podrobneje razloženo delovanje.

Kot kaže ta mašina ni samo goli predojaèevalnik.
Meni so te funcije poznane iz pro audia, sicer z drugaènimi imeni.
Equalizer, compressor, limiter , expander, de esser.
Pogruntaj kako se vse to odklopi v nulto pozicijo - bypass. in ba zadevca še najbolje zaigrala.

V tem èlanku sicer predhodnega modela je razloženo.
-----------------------------------------------------------
The most interesting feature of the amplifier is a noise suppression system using 'auto-correlation' technique.

This is as effective as the Dolby noise reduction system but different. The auto-correlation can be used with a tape recorder which is already fitted with a Dolby system and the overall noise reduction will be a cumulative effect.

---
Even this is not the end of the features. A third one is a volume expander which can undo the volume compression which often has to be used in the recording process to reduce signals of exceptional dynamic range to a relatively constant signal level suitable for recording.
