If you’re here to learn about preamps and channel strips, and the differences between them, you’ve come to the right place. While both are designed to improve audio signals, their functionality and applications differ. In this guide we’ll explore how the two types of units are different and offer some product examples to give you a better idea of what you may need for your studio or live performances.
What Does a Preamp Do?
The basic function of a preamp is to boost low-level signals from microphones and instruments to the right level for processing and amplification. Preamps are integral to a setup because they ensure that the signal is strong enough to be processed by other equipment without introducing noise or distortion. Preamps can also potentially add color to your sound and give it character by shaping the tonal qualities of your vocals or instrument.
It's worth noting that your audio interface comes with a preamp built in, so it’s unlikely that you’ll need an external preamp to complete your setup, especially if you’re working in a home studio. That said, if you’re unhappy with the sound of your current interface, or if you’re having a band come over and you need more inputs, a preamp can optimize sound quality and potentially accommodate a larger number of instruments and mics.

What Does a Channel Strip Do?
In its most classic form, a channel strip is simply a mic, instrument, or line input that translates to a channel on a mixing board. It features a column of knobs, buttons and faders that allow you to process the sound in a number of different ways. And if you think of a typical mixer, you’ll see a bunch of channel strips on the console. An average mixer has anywhere from 2 to 48 channel strips.
But channel strips are no longer limited to the large mixing consoles you see in studios and live venues. Now, you can find a single, standalone channel strip that has its own power supply. You can simply plug your mic or instrument into a channel strip unit and do all your sound processing on it (like equalization, compression, de-essing, etc.) without having to buy an entire multichannel mixer, which can be bulky and costly. In fact, it was partly for these reasons that channel strips were invented. Furthermore, a standalone channel strip also tends to provide a cleaner signal for recording.
How does this all tie back into preamps? The advantage of a channel strip over just a preamp is that it combines a preamp system with this extra processing functionality. This makes it a useful tool for not only amplifying your signal but also for shaping and refining sound during recording or live performance. In short, it’s an all-in-one solution.
But while channel strips are often essential in live situations, are they as necessary in home studios? As mentioned above, your interface will provide you with your preamp needs, while your DAW offers channel strips/plugins that can deliver the same functionality as an external channel strip. That said, some people prefer the tactile experience of dials and buttons, while also being able to choose the sonic character of the preamp before it reaches the digital domain. If you’re a studio nerd like me, it’s a fun toy to add to your collection.
Now, let’s look at some examples of preamps and channel strips to get a better idea of what you can expect from both types of devices.
Budget-Friendly Preamps
The Focusrite Scarlett OctoPre Rackmount Eight-Channel Microphone Preamp is a versatile and wallet-friendly preamp option. Focusrite makes solid technology in general, from their cheapest home studio interfaces to their more professional gear. Offering eight channels of preamplification, the OctoPre is a great choice for those who need more inputs than their interface can provide. If your room is big enough, you can invite your whole band without having to pay premium prices for studio space.
High-End Preamps
The Rupert Neve Designs is one of the most famous brands on the market, whether you’re dealing with preamps, channel strips or DI boxes. The 5025 Dual Shelford Microphone Preamp provides two channels of flagship preamps that offer a lot of versatility; the unit makes it easy to fine-tune the amount and type of harmonic content. So, whether you want something pure and transparent for your vocals or deep and robust for your electric guitar, this preamp will cover all your bases.
Budget-Friendly Channel Strips
One of the top sellers on the market is the dbx 286s Microphone Preamp/Channel Strip. It’s not only popular for being easy on the wallet, but it also delivers super clean sound, whether you’re using a microphone or instrument. It includes four processors that can be used independently or in combination, so you don’t have to mess around with patching together multiple processors on one track. In addition to switchable phantom power and a high-pass filter to reduce those low frequency rumbles, you’ll also get the dbx OverEasy compressor that can smooth out uneven acoustic tracks or deliver intimate sounding vocals. Another handy feature is the de-esser, which minimizes any pesky sibilance.
The Solid State Logic SiX CH500 Series Channel Strip uses the technology from the famous SiX console, offering a button that allows you switch between a mic, line or Hi-Z input. (Yes, like the example above, you can plug in your instruments without a DI Box). It provides phantom power in addition to simple two band EQ controls. Also, a single-knob compressor is included too. So, while it may be simple to use, this channel strip gets the job done skillfully.
High-End Channel Strips
I have to mention this brand again because it’s so well-known; like the Shelford preamp example above, the Rupert Neve Shelford Channel takes the classic Neve preamp sound and adds a bunch of tools to give you complete control over your signal processing. It’s also highly versatile in terms of what it can deliver, offering an uncolored, pristine sonic profile, as well as variable saturation modes to give you that renowned Neve vintage flavor. And of course, you’ll get the usual features found in a channel strip such as an EQ section, compressor and high-pass filter. Another nifty function is “fast mode,” which alters the speed of the attack and release.
If you’re looking for a particularly warm and fat sound, you can go with a tube processor like the Avalon Design VT-7373SP. It combines a tube microphone preamp, microphone and instrument input, along with a four-band EQ and a compressor that delivers full dynamic control. If you’re hungry for a vinyl feel, a tube preamp is always a great addition to your studio setup.
