What to look for when buying Thunderbolt audio interfaces buying guide

Formal aspect

Most audio interface housing materials are comprised of aluminum, steel, or metal. Plastic is rarely used to make devices. In this situation, your preference is a question of taste or is determined by the manufacturer.
The Antelope Audio Discrete 4 is an example of one of these devices that may be used as a desktop or mounted on a rack. Everything hinges on your needs.

Sources and recipients

Vocals are the only sound sources that can be captured by a microphone, followed by acoustic or electric guitar, piano, and hardware synthesizers, or instruments of a similar nature.

To put it another way, you typically require a maximum of two channels at once in various fields of endeavor, including microphone preamps for recording in mono or stereo – depending on the instrument.

On the other hand, the audio interface needs to have at least eight or more inputs if you wish to simultaneously record entire bands with drums. Depending on the size of the formation, even huge audio interfaces with ten inputs reach their limits because the drums alone frequently consume four or more input channels.

If many signals are to be played out of the DAW at once, it appears the same on the outputs side. For example, this may be used to add summing to an analog mixer, add a second summing mixer for a fuller sound, or simultaneously play multiple independent headphone mixes.

You should always account for enough inputs and outputs as well as any expansion options in your budget, depending on the size of your recordings in terms of inputs and outputs.

microphone preamps

A microphone preamp is a need whenever you want to record using microphones. As a home recorder, you must have at least one preamp. At first, the electrical signal that the microphone emits is far too faint and silent to be adequate for high-quality recordings.

A microphone preamplifier is thus always required. The microphone signal is first amplified to a level that is considered to be the working line level.

The fundamental criterion is that an audio interface’s built-in microphone preamplifier operate tonally as neutrally as feasible, or without coloration and noise.

This indicates that the audio interface is sound-compatible with all devices. External preamplifiers can be utilized first, as is traditional practice, if more preamp sound coloring is needed.

It does, however, cost a lot of money. As an alternative, certain audio interfaces include built-in sound coloring options, such as the Apollo Twin X QUAD from Universal Audio with its unique Unison preamp technology.

We especially advise external microphone preamps if you wish to have a “fat” vintage sound full of overtones. This can be done in conjunction with an AD/DA converter and integrated into your audio program.

Condenser microphones require an additional supply voltage of 48 volts on phantom power in order to operate at all. As a result, in order for a condenser microphone to emit a signal when attached to a microphone preamplifier, the 48-volt phantom power must be turned on.

A brief digression: Dynamic microphones and condenser microphones are the two main categories of microphones. The use of dynamic microphones makes it the simplest to explain how it all works. Similar to a bicycle dynamo, these operate on the basis of a moving coil or ribbon.

As a result, when sound waves strike the membrane of the microphone, an induction coil is moved, which produces a very modest alternating voltage. In order to provide the extremely high amplification power necessary to raise the weak output signal to a sufficient working level, particularly with ribbon mics, an additional microphone preamplifier is needed.

Contrarily, capacitor microphones produce slightly louder output signals than dynamic mics, in part because of their various design principles. However, a microphone preamplifier is also necessary in this situation in order to provide the operating voltage for condenser mics as well as to reach the line-level required for useable recordings.

As a result, a switch for said supply voltage, also known as phantom voltage and operating at a standard 48 volts, is always present in a microphone preamp. The name comes from the fact that this supply current is typically only utilized to operate the microphone capsule, which is constructed in the shape of a capacitor, and not any further built-in amplifier circuits.


You shouldn’t experience any issues with sound performance using the interfaces we’ve chosen for this tutorial. Watch out for reviews that criticize other models for having sound quality problems, such as preamp hiss. Preamps on non-professional interfaces can occasionally be of middling quality. They could “blow,” or create undesired interference, if pushed too hard to make up for a weak audio stream.


Regardless of whether it’s an Apple or Mac computer, a thunderbolt audio interface must of course work with it. The majority of the gadgets in our study of audio interfaces work with both iOS and macOS. But be mindful of the operating system’s age: Older versions cannot be used with many models.

Depending on the device, different audio interface software may be included. While some audio interface models only include about three programs and tools, more flexible devices typically include a far wider selection of programs, tools, and samples. Find the ideal gadget for you by comparing, for instance, Universal Audio’s products with those of other manufacturers.

Sync Sources

You have Word Clock, the PreSonus Quantum 2626, and the Zoom TAC-8, for instance, as sync sources. However, sync sources like ADAT, Internal, and S/PDIF are combined in the Apollo Twin X QUAD. But what are DAT, Internal, S/PDIF, and Word Clock?


Even with a little catch, ADAT is still still less expensive than an extension through an additional interface instance. The format has a limit on the audio resolution. This means that a maximum resolution of 48 kHz/24 bit is the only one that can be achieved when all eight of the available ADAT input and output pathways are used concurrently. The fact that modern ADAT interfaces offer an additional data transfer extension known as S/MUX, which only allows higher sample rates when the number of available channels is limited, is a tiny consolation. You can select either two channels at a time at 192 kHz or up to four channels at a time at a sample rate of 96 kHz when using S/MUX mode.

On the other hand, you cannot avoid cascading with additional audio interfaces if you wish to reliably record at the highest resolution on all available channels at the same time. Typically, this is more expensive than an ADAT converter. However, the complete interface network’s unfettered, full channel power is accessible in terms of recording quality and convenience. Another benefit of the ADAT interface, in addition to the economical system expansion, is the lossless, digital data transmission across optical fiber optic cable.

The plus: Sound changes could occur if the data stream from and to the linked peripheral device had to be translated back and forth between analog and digital signals. Instead, everything continues to exist in a wholly digital format of zeros and ones, and the shipment of optical fiber optic cable has no impact on this.


Currently, the S/PDIF interface primarily uses chinch or RCA cables, although it also operates entirely digitally. This is from the consumer or home theater sector, where optical TOSLINK communication is typically used to send data. Similar to ADAT in S/MUX mode, this transmits a stereo signal, or two channels at once, with a maximum frequency of 192 kHz and a word length of 24 bits. In contrast to ADAT, only two channels are broadcast, however thunderbolt aes/ebu interface are of good quality overall, and the data is often transferred by a cinch or RCA cable connection rather than an optical link. High-quality mono or stereo recordings, such as those made with a digital mixer or a high-end AD/DA converter, as well as fully digital signal forwarding to studio monitors with S/PDIF capability are examples of possible applications. Therefore, you can employ lossless digital data transmission if you prefer the specifically designed converters in your studio speakers with S/PDIF interface to AD/DA converters in your audio interface.

BNC (World Clock)

Last but not least, word clock inputs and outputs make up the third digital interface after ADAT and S/PDIF. They come in the form of so-called BNC sockets if they are offered by the corresponding audio interface model. However, they don’t transmit audio signals this time. However, they send a signal to a world clock, or “word clock,” to synchronize the digital sampling rate throughout a network of various digital devices.


Different thunderbolt audio interfaces have different storage needs. The Antelope Audio Discrete 4 only needs 10 gigabytes of storage, compared to the PreSonus Quantum 2626’s 30-gigabyte need. In any case, the sweet spot is 8 gigabytes. Nevertheless, 4 gigabytes can also operate your applications without stuttering and without taxing the computer to its limits. However, you’ll require drive space.


Naturally, your options will be more varied the greater your budget. Nothing, however, precludes you from starting out with an entry-level model in the home studio market. However, make sure you select models from reputable and well-known manufacturers. (Focusrite, Steinberg, Behringer, Universal Audio, RME, etc.). As a result, you will have a greater chance of getting a good tool. Budget between $1,300 and $1,500 if you want a high-end thunderbolt audio interface like the Apollo Twin X QUAD. A budget option, such the Zoom TAC-8, can be purchased for half that much.

What is a Thunderbolt interface?

Thunderbolt is a high-speed input/output (I/O) technology developed by Intel that allows for fast data transfer between computers and peripherals, such as external hard drives, displays, and audio interfaces.

How fast is Thunderbolt?

Thunderbolt 3 has a maximum data transfer rate of 40 Gbps (gigabits per second), which is twice as fast as Thunderbolt 2 and four times as fast as USB 3.1. This allows for lightning-fast transfer of large files and data sets.

What devices can I connect to a Thunderbolt interface?

Thunderbolt interfaces can be used to connect a variety of devices, including external hard drives, displays, audio interfaces, and other peripherals. Thunderbolt 3 interfaces also support USB-C connectors, so you can connect USB-C devices as well.

Do I need a Thunderbolt interface if I have USB-C?

While USB-C and Thunderbolt 3 use the same physical port, Thunderbolt 3 offers faster data transfer speeds and more connectivity options than USB-C. If you require high-speed data transfer or need to connect multiple devices simultaneously, a Thunderbolt 3 interface may be a better choice.

Can I use a Thunderbolt interface with a Mac or a PC?

Yes, Thunderbolt interfaces are compatible with both Mac and PC computers, as long as they have a Thunderbolt 3 port or a Thunderbolt 3 adapter.

Are Thunderbolt interfaces expensive?

Thunderbolt interfaces tend to be more expensive than other types of interfaces, such as USB or FireWire. However, they offer faster data transfer speeds and more connectivity options, making them a good choice for professionals and power users who require high-performance I/O.

Can I daisy-chain devices with a Thunderbolt interface?

Yes, Thunderbolt interfaces support daisy-chaining of up to six devices, so you can connect multiple peripherals using a single port. This can help reduce cable clutter and simplify your workspace.

Is a thunderbolt audio interface better than a usb audio interface?

Thunderbolt connections have a few advantages over USB connections, including higher data speed, which lowers latency while monitoring audio and boosts the capacity to handle audio effects and plugins in real time.

Why should I use a thunderbolt interface?

Thunderbolt offers its own set of benefits. It is closer to the hardware and produces much larger bandwidths and slightly lower latency, but this is only visible with multi-channel interfaces, which are not included in this group. Thunderbolt is also a pain in the neck when it comes to hot plugging, so you might have to restart the computer every now and again if it loses connectivity — not cool on stage. However, Thunderbolt has a big advantage: it can transmit substantially more current. As a result, high-quality, compact interfaces don’t need a separate power supply. That’s cool in any situation, not just when you’re on the road a lot. The Thunderbolt version of the Universal Audio Apollo Twin X is the greatest example here.

Are Thunderbolt audio interfaces also compatible with Linux?

Thunderbolt audio interfaces are primarily intended for use with Apple and Mac computers. If you require a Linux audio interface, consider the Behringer Xenyx Audio Interface, Yamaha AG03 3- Audio Interface, Focusrite Scarlett 2i2 (3rd Gen), Tascam US-44, or Native Instruments Komplete Audio 6 Mk2.
