Forskjell på mikrofon

[Ludde]

Hver er forskjellen på Beta 58 og beta 58 A?


Snakka med en tekniker som sa at Beta 58 var best for mannlig vokal og sm 58 var best for kvinnelig. Ett par dager etterpå traff jeg på en annen som sa det stikk motsatte..

Noen som vet?

beta58a veier hele 20 gram mindre enn beta58.

Er det det eneste?

sm58 cardioide og b58a en supercardioide... ulike frekvensresponser... kanskje litt viktigere enn vekt???

edit: Beklager en "liten", men vesentlig trykkfeil fra min side. Jeg sammenlignet de som var listet opp, sm58 vs b58a. Men kom i skade for å skrive b58 i stedet for sm58...

[aslak.skarderud]

definitivt.

[Ludde]

sikkert..

hva er forskjellen på supercardioide og cardiode??

Bare så det er sagt: Beta 58 og Beta58A er begge supercarioider. Gode gamle SM58 derimot, er en cardioide.

De tekniske spesifikasjonene Kenneth har gjengitt litt lenger opp på siden gjelder så vidt jeg kan se også SM58 vs. Beta58A.

Forøvrig fant jeg dette hos http://www.shure.com:

"Originally the Beta 58 was available as the the Beta 58C (chrome grill) or the Beta 58M (matte grill). The Beta 58C was eventually discontinued and the Beta 58M became just the Beta 58. The Beta 58 was then discontinued and replaced by the Beta 58A." ... "The Beta 58A has a completely new cartridge in it. While the new cartridge is meant to mimic the old cartridge as far as polar pattern, output level, and frequency response goes, it is a different cartridge and will sound slightly different. Two major differences are that we removed the hum bucking coil on the new model and added an output transformer."

Ikke mye å bli klok av der heller Personlig mener jeg forskjellene er så små at det ikke er verdt å bruke energi på å finne ut av Er vel bare SM 58 og B58A som selges nå om dagen uansett...
