Buyer’s Guide

The choice of any equipment may become a tough challenge, if you don’t have enough background knowledge about its construction and performance. If you would like to purchase a reliable preamplifier under $500 from a reputable brand, here are some of the things to bear in mind.

Preamplifier Notion

The preamplifier is designed to convert a weak signal into a stronger one. The sound amplifier is located near the signal source itself. This makes it possible to receive the signal and immediately transmit it without changes to the power amplifier. A weak signal output can come from a microphone, pickups, turntables, and even a receiver. The device is most often used in Hi-Fi and High-End audio systems to connect individual components of an audio system, as well as to increase the voltage.

You can adjust the device’s functionality with the help of the front panel toolbar. In the rear part, there are connectors for linking an amplifier, a microphone, a turntable, and other devices. To get a number of sound options, the devices are equipped with knobs for reducing or amplifying sound, timbre, and various frequencies.

Preamplifier Purpose

The main task of the device is to amplify the signal to a level that is more acceptable for amplification by power amplifiers — end amplifiers. The preamplifier selects the same signal level from different sources, that is, a signal from any source is connected through the amplifier. By enhancing the power of the signal, the device changes the sound timbre. With the help of reproducing equipment, linearity is achieved with minimal distortion.

With some preamp models, users can change the sound performance and get new tones. It is achieved by overloading some internal components of the device. These models are designed in such a way, so that it is possible to turn on the necessary overload mode.

Preamp Functionality

What technical capabilities should a preamplifier provide? The number of input channels is an important quality indicator. However, to choose the best model, you have to take into consideration the properties of your system and how many elements it possesses.

The option to provide phantom power for the microphones is almost always present: it should be possible to turn off the power if necessary. The model should have manual gain control: it can be smooth or stepped.

The preamplifier may have a low pass filter. This function allows you to cut off all possible low-frequency interference from the signal, including various kinds of interference, the hum of some instruments, etc.

Another parameter that shows the quality of a product is the signal-to-noise ratio: it should be as high as possible. The main thing here is that the preamplifier itself has a minimum noise level.

FAQ

Does preamp influence the system’s sound quality?

Of course, a lot depends on the functionality of the model you have/will choose. On the one hand, this device is considered to simply perform the function of cleaning the signal from hums and bringing to the desired quality level. On the other hand, it can include such adjustments as bass and treble controls that obviously affect the sound performance.

Can a preamplifier be a substitute to an amplifier?

The functionality and general purpose of preamps and amplifiers are totally different. Preamplifiers can’t be used on their own, while amplifiers are more independent in this case. Without a doubt, a preamp is an auxiliary device.

Conclusion

A lot of equipment do have built-in preamps already. However, if you desire to boost up the power of your system and increase sound quality, then it is a beneficial investment. With the help of our guide, you can select the best models that will suit your budget and objectives. Just give them a try!
