![]() Whatever your audio recording improvement needs, using a dedicated microphone preamp will result in a finer, cleaner and more transparent sound. If this is the case, a tube or valve microphone preamp would be ideal. You want to give more breadth, depth, dimension, detail and clarity to the sounds you are going to record.You want to increase the number of inputs to your interface or audio system.By the way, ribbon microphones, like dynamic moving coil microphones, have a very low signal-to-noise ratio, and therefore require more gain to optimize the perception of the sound signal at the input. Your mixer, sound card or audio interface has a microphone preamp built in, but it doesn’t have enough power to generate enough gain.Your premium professional microphone (dynamic or condenser) should only be connected to audio recording equipment with line inputs.However, its purchase is recommended for one of the following reasons: If you already have one and are using it, you may not need to purchase a dedicated microphone preamp. Mixers, audio interfaces and sound cards for professional use generally already have an internal microphone preamp. To do this, they will only need to be connected to a microphone preamp (input) and an audio amplifier (output) to distribute the sound through the speakers. Equalizers and compressors can also receive these types of signals. ![]() If you are using several multimedia devices, you should also consider purchasing a receiver, a UHF decoder, a signal splitter, and several converters so that you can truly have a complete studio setup.The microphone preamp and the conventional amplifier are not the only devices that can work with line-level signals. The same is true when you want to bring out the sound from a subwoofer with RCA connections. If you intend to connect your mixer or DJ mixer output to a home theater amplifier, the use of an adapter and specific cables may sometimes be necessary. ![]() Technically, by “line level” we mean the audio signal that is picked up and amplified from a few millivolts to about 1 Volt. This operational amplifier strongly accentuates the gain at its input to boost the sound that will come out towards the powerful 120 to 150 Watts speakers.Īn ordinary Class A amplifier is used to distribute the line level signal to all types of speakers (Hifi, Home Cinema, Subwoofer, wired or even wireless speakers…). You can also choose to bring out the sound to be able to amplify it further at the output with an Op-Amp. The sound emanating from the turntable with phono cell comes out clean, crisp and perfectly balanced to be amplified with a receiver and output to the speakers and to a headphone or headphone output for monitoring. ![]() And similarly for a phono preamp, it amplifies and embellishes the sound emanating from a turntable at the input via a dedicated mixing console. It’ s the classic audio amplifier, the power amplifier. The sound that has already been processed and that is to be output through the speakers must also be amplified.Ī microphone preamp cannot perform this function. The second ( the power amplifier) amplifies the sound at the output. The microphone preamplifier and the classic audio amplifier have (in common) an essential role which consists in amplifying sound, but the similarity ends there! The first, the mic preamplifier, amplifies the sound signal at the input to perfect the audio processing. The sound quality will be much better if you combine it with a mixing desk and a sound card with an internal preamplifier. The use of a good quality, high performance microphone preamp will guarantee an almost perfect recording quality.
