A preamp is a component that converts low-level signals into more powerful ones before sending them to an amplifier. It also provides additional features such as equalization, tone control, balance, and volume control.
Essentially, a preamp is the primary control unit in a stereo or home theater system. It switches low-level signals from audio and video sources, such as a radio tuner, phonograph, tape recorder, or CD player, to the audio amplifiers.
The preamp is typically a standalone piece of equipment, but can sometimes be included with a speaker. It is a vital part of an audio system, because it makes it possible to have multiple sources of playback without needing to use an external amplifier.
You can easily connect a preamp to an amplifier by using RCA cables. These connectors are normally red on the right side and white or black on the left. Plug one end of an RCA cable into the preamp’s line-in inputs, and the other into the amplifier’s pre-outs.
An external preamp is a handy device to have on hand, especially if you are a podcaster. It can boost the signal coming from a microphone so that it is better suited for recording. It can help you record the sound more accurately and give it a better quality, making it easier to mix.
Many of these preamps also come with their own effects, such as EQs and compressors. These are great for giving your audio more flavor and character, which can save you a lot of time in the long run.
Another great thing about these preamps is that they often feature colored microphone inputs. This can make your voice more complex, which is useful when mixing because it allows the voice to find its place in the mix better.
Whether or not you want a colored mic input depends on what kind of music you listen to and the type of voice you want to capture. Generally, it is better to use a cleanly boosted signal from the source for recording, but a colorful option can be worth considering.
How to Connect a Preamp to an Amplifier
First, ensure that your preamp is turned off before you start hooking up the equipment. This will prevent you from running into any electrical hazards and allow the two devices to be connected safely.
The next step is to connect the mic to the preamp’s microphone input. XLR cables are ideal for connecting a microphone to an external preamp, because they feature a longer pin that attaches to the ground and two shorter pins that carry the mic signal. This allows you to connect and disconnect the cable without picking up any other external signals that may harm your microphone.
Once you have the mic plugged in, turn on the receiver and adjust the preamp’s volume until you are satisfied with the sound. Be sure to lower the volume a bit before turning it up again so that you don’t damage your speakers or hearing.
