Preamps are very useful devices for recording and live performances, shaping the sound of the audio that is captured through an input. Having a preamp with ADAT optical outputs installed will expand the options you have to work with.
ADAT may seem confusing, but it is simply an optical audio feature that is capable of transferring digital audio from two devices. ADAT stands for Alesis Digital Audio Tape and gets its name from the popular 8-track recorder released in the early 1990s.
The optical output that we call ADAT is capable of transmitting eight channels of 24-bit audio, uncompressed, and at 48kHz in one direction. This makes it easy to add additional mic inputs to your recording rig.

How We Tested
To test these preamps with ADAT optical outputs as accurately as possible, we began by monitoring the sound quality of the inputs. By connecting different mics and instruments to the preamps, we were able to rate their transparency and tone and identify any noise issues.
Next, we tested the quality of the onboard controls and parameters to see whether they contributed positively to the functionality of the preamps. Finally, we assessed the ADAT optical outputs and how effective this feature was.

Preamps with ADAT Optical Outputs Buyer's Guide
Due to a wide variety of preamps being available for different purposes, it’s easy to get confused by the many specs and features these devices boast. Preamps with ADAT optical outputs are great for expanding your recording rig beyond its current capabilities.
Preamps are devices that are unfairly categorized as complicated to understand, but this is simply because they can be used in many ways. In reality, a preamp is designed to improve the sound of your existing audio equipment.
Understanding the basics of how a preamp works and why ADAT optical outputs are such useful additions will allow you to maximize the positive impact the device you choose has on your overall audio rig.
Whether you’re recording music, capturing audio for podcasts or other content, or you want to expand your live sound setup, a preamp with ADAT optical connectivity is a must-have device.
You can find more detailed information on preamps with ADAT in our buyer’s guide below.
Things To Consider When Buying
Consider the number of channels
The more channels a preamp device has, the more sound sources you will be able to record or process simultaneously. For example, having six inputs will allow you to mic up each drum individually if you’d like to use the preamp for recording a live drum kit.
Think about coloration
Preamps that are installed on the mic and instrument-level inputs are designed to add color to the signal. Some sound more transparent, while others produce a warmer sound. It’s important to consider the sound you want because the coloration cannot be removed once it’s recorded.
Consider rack mounting
Depending on the specifics of your studio setup, you may want to consider purchasing a preamp with ADAT optical outputs that are rack-mountable. This will allow you to keep all of your outboard gear in one place and easily transport it for recordings or live performances.
Identify the effects you need
The best preamps and recording devices often come with onboard effects and processing tools. EQ, compression, reverb, and delays are four of the most common features that you’re likely to find on these devices.
Mic/Instrument Input Preamps
The quality of a recording device is largely determined by the microphone and instrument preamps installed on the inputs.
When you compare the preamps featured in our guide, you’ll commonly see preamps described as “Class-A.” This indicates that the preamp is of the highest quality, so it’s a good idea to look out for this description.
Some of these devices have vacuum preamps on the inputs for mics and instruments. This leads to a vintage-style recording sound, with the warmth of a tube-driven device.
High impedance instrument and line level inputs are also great for direct recording electronic instruments, effects, or samples into your preamp device.
Digital Conversion & Dynamic Range
Conversion is an integral process for any digital preamp recording device and is dependent on the quality of the converters used by the manufacturer.
Preamps that boast 24-bit/192kHz conversion will perform flawlessly, reducing the chance of lagging or glitching when connected to a computer.
The AD/DA conversion is even more important when looking for a preamp with ADAT optical outputs, as expanding your recording rig will require maximum efficiency to prevent any issues.
Another thing to look out for is the dynamic range of the preamp, as this will determine how much variation there is between the quietest and loudest signal it can receive.
A preamp with a dynamic range in the region of 110dB will give you plenty of headroom to record instruments and vocals without worrying about distortion.
How Many Channels Do You Need?
The number of preamp channels installed in a single unit will determine its flexibility. Indeed, you can use the ADAT connectivity to expand the number of inputs you have to work with, but choosing a device with an adequate number of inputs is a good idea.
For example, if you want to record an acoustic drum kit, you might need microphones for the kick drum, snare, toms, overheads, and a room mic to get a detailed recording.
Choosing a preamp with enough inputs to facilitate the recording you want to make will ensure you’re not limited to a certain number of microphones.
Preamps with ADAT Optical Outputs FAQs
How Does a Preamp Affect Sound?
A preamplifier can affect the sound of instruments and microphones significantly. Its role is to prepare the audio for amplification, and it does so by enhancing certain frequencies, adding warmth, or altering the coloration of the sound.
Every preamp affects the sound of recordings differently. For example, a tube preamp will produce a warmer sound than a solid-state preamp, which is likely to sound more modern and sharper.
Is a Preamp the Same as an Audio Interface?
Preamps and audio interfaces are often confused for one another, but in reality, these two devices are very different. An audio interface may include preamps on its inputs, but these components are just one part of the entire recording device.
A preamp is a specific device that comes before a power amp in the gain stage and can be used to shape the sound and dynamics of an audio signal. An audio interface is an all-in-one hub for recording, monitoring, and playing back audio.
How Much Gain Does a Mic Preamp Provide?
Microphone preamps vary in terms of how much gain they can add to the signal, but in most cases, they are designed to supply between 30-60dB of gain.
Preamps designed for low-level mics will provide more gain than those designed for recording with normal condensers and dynamic microphones.
