✔ Ganancia activa de limpieza
✔ Alimentado por fantasma.
✔ Plug & Play
✔ Reduce el ruido.
Dinámico y potente:
El amplificador de micrófono OFCOSH puede funcionar con casi cualquier micrófono de cinta dinámico o pasivo.
【Da un micrófono dinámico de hasta 25 dB 】
El preamplificador de micrófono OFCOSH aumenta enormemente la intensidad de la señal del micrófono dinámico, ayuda
micrófono dinámico para grabar voces suaves e instrumentos acósticos.
Sin daños al micrófono de 48 V.
El amplificador de micrófono OFCOSH protege a los micrófonos de los efectos adversos de la potencia fantasma.
Compatibilidad perfecta:
Perfecto para podcasts, transmisión en vivo, transmisiones de radio, sonido en vivo y grabación de estudio.
¿Cómo funciona? 】
1. Conecta la salida del amplificador de micrófono a un dispositivo que puede suministrar +48 V fantasma
potencia, como un preamplificador, consola de mezcla o interfaz de audio.
Dependiendo del equipo utilizado, el amplificador de micrófono puede estar más cerca del micrófono o el preamplificador cuando se utilizan cables largos.
2. Conecta cualquier micrófono dinámico, cinta o tubo a la entrada del amplificador de micrófono.
El amplificador de micrófono no pasa a través de la alimentación fantasma, por lo que es seguro para
micrófonos de cinta delicados. Para micrófonos que requieren +48 V,
como condensadores, es necesaria una fuente de alimentación fantasma externa separada.
3. Comienza con la configuración de ganancia más baja, luego activa la potencia fantasma de +48 V.
en tu dispositivo (preamplificador, mezclador, interfaz, etc. ).
Aumenta gradualmente la ganancia a tu nivel preferido.
Nota:
★ No es compatible con micrófonos de condensador.
★ Se necesita alimentación Phantom de 48 V, no incluida en el paquete.

I've been playing music for over three decades. I've done my share of shows, and being on the instrument side of recording. Recently (3-4 years ago) I started writing and recording my own stuff.I'm not an audiophile, or perfectionist, but I do have a good ear and try to keep things sounding as good as I possibly can.That said:This little bugger does increase the signal from the dynamic mics I'm using. I have unplugged it, recorded a minute or two, then plugged it in and recorded a minute or two. I do notice a slight difference, but if your vocals are going over music, or the instrument you are recording will be mixed with other tracks, the difference is negligible. I mean, if you have a perfectly sound dampened studio and really nice studio monitors, you might notice a little difference in tone.But, the majority of people that will hear your music will listen on stock car stereos, bluetooth speaker, or earbuds. You will get more tonal differences between two brands of bluetooth speakers than from the preamp.If you're a pro and listen to every track independently through good studio monitors, this might not be for you. If you're a prosumer that loves to write and record, and aren't as worried about slight tonal differences, -or can EQ and mix for them- it is a great little preamp.Not that a stronger signal does my off-key attempt at singing any favors...

I have been doing audio recording for well over 20 years, microphones being the first thing I learned to use - with Shure dynamic & condenser mics - and a variety of microphone preamps which were mostly pretty terrible compared to the average mic preamp you'll find on even $100 USB audio interfaces today, which are OK. I am explaining this because any professional audio engineers will tell you that obtaining a good microphone signal sound depends on the quality of the preamplifier (aka "preamp") almost as much as the microphone itself. Many budget/portable recording interfaces or mixers have built-in mic preamps which are lacking in the amount of gain (preamplification) and/or +48V phantom power (often as low as 12V) they can provide. Sometimes you don't have a mic-level preamp at all - such as on my Roland MC-909 or Behringer UCA-202 - so I thought this neat little in-line preamp could provide such gain in a pinch but after testing it and thinking it over more, it doesn't make much sense because this device requires +48V phantom power over an XLR cable and I cannot think of a single product I've ever seen / heard of which is capable of providing this but doesn't do preamplification as well (more often you'll get only the preamp, but no phantom power).This can't be used with condenser mics, at least not without a second XLR with +48V phantom and second XLR cable, because condensers require the phantom power and this uses it for preamplification. So then the only cases in which it'd be helpful are if you're using it with a ribbon mic (these are notoriously low output) on an interface/mixer's mic preamp as these often have +48V but only 50 to 55db of gain. Its unlikely you'll get a good sound with an inexpensive ribbon mic, so if you're going to use a ribbon mic I'd suggest getting a dedicated mic preamp. The other situation when it could make sense is if your dynamic mic has got a weirdly low-level output or if you're working with XLR connectors for a stagebox and you need to boost the signal coming from your line-level device (sampler, looper, keyboard, etc)In my brief testing it did not seem to provide 25dB of gain, maybe 18-20dB of gain. Fortunately I wasn't able to notice any degradation to the sound of my singing with an Electrovoice microphone via my RME Babyface preamp/interface.

This product does work as intended, but it produces some buzzing noise that is not ideal. I have tried the preamp with 2 microphones, the Shure SM7b and the Rode PodMic, so if you have these microphones and you don't want any humming or buzzing, please increase your budget and go with something like a triton fethead, or a cloud lifter. Both of those products would be better if buzzing and humming is not something you want. But, if you do not care about that and only want some extra gain for your gain-hungry microphone then this preamp is for you, though I will say, the buzzing is extremely noticeable in something like a podcast or a recording session.

I used to have my soundcard gain on level 60 to have a good mic gain but with this little gadget, I o ly have my gain on level 25 and my mic picsy voice like a condenser mic..without picking any external sounds from within.
