Connecting two audio interfaces via ADAT?

As a musician, podcaster, or content creator, you know that having a quality audio interface is essential for recording high-quality audio. However, even the best audio interface can have limitations when it comes to the number of inputs available. Fortunately, there are several ways to add more inputs to your audio interface, and in this post, we'll explore some of the most popular options.

1.Upgrade Your Audio Interface

One of the easiest and most straightforward ways to add more inputs to your setup is to upgrade your audio interface. Many modern audio interfaces offer a range of input options, including XLR, TRS, and MIDI inputs, as well as digital inputs like S/PDIF and ADAT. When upgrading, make sure to choose an interface that fits your specific needs and budget. If you're a podcaster who needs to add one or two additional microphones, a two- or four-channel interface might suffice. However, if you're a musician who needs to record a full band, you'll likely need an interface with eight or more inputs.

2. Use a Mixer

Another option for expanding the number of inputs on your audio interface is to use a mixer. A mixer is a device that allows you to combine multiple audio signals into one output. Simply connect your microphones or instruments to the mixer's inputs, and then connect the mixer's output to your audio interface. Mixers come in a range of sizes and prices, from compact two-channel mixers to large 32-channel mixing consoles. Mixers can also provide additional functionality, such as EQ, effects, and routing options.

3.Use a Digital Interface (ADAT)

If your audio interface has a digital input, you can connect it to a digital interface like the Behringer ADA8200. This will allow you to add up to eight additional inputs to your setup. Digital interfaces are often more affordable than upgrading to a higher-end audio interface. However, it's important to note that using a digital interface can add some latency to your signal, so it may not be the best option for recording live performances.

4.Use a Preamp

If you need to add just one or two additional inputs, a preamp may be a good option. A preamp is a device that amplifies your microphone or instrument signal and converts it to a line-level signal that can be connected to your audio interface. Some preamps even come with built-in EQ and compression. This option is a great choice for those who don't need to add a lot of inputs but want to improve the quality of their recordings.

No matter which option you choose, it's essential to test your new setup before recording anything important. This will help you identify any issues and ensure that you're getting the best possible sound. It's also important to choose the option that best fits your needs and budget. Upgrading to a higher-end audio interface might be the best choice if you need a lot of inputs, while using a preamp might be the best choice if you only need to add one or two. Ultimately, the key is to choose the option that helps you achieve your recording goals while staying within your budget.

So ADAT?

ADAT (Alesis Digital Audio Tape) is a digital audio interface standard that was introduced in 1991 by Alesis. ADAT uses a lightpipe optical cable to transfer up to eight channels of digital audio between devices. ADAT was originally designed for use with Alesis' own ADAT digital tape recorder, but it quickly became a popular standard for connecting audio interfaces, mixers, and other digital audio devices.

ADAT uses a lightpipe interface that transfers digital audio data using light pulses transmitted through a fiber optic cable. The lightpipe interface can transmit up to eight channels of digital audio at a time, and multiple lightpipe interfaces can be daisy-chained together to increase the number of channels. The data is transmitted at a sample rate of up to 48 kHz and a bit depth of up to 24 bits per sample, which is the standard for most professional digital audio applications.

ADAT devices typically have both ADAT input and output ports, allowing them to send and receive digital audio signals. For example, an audio interface with ADAT input and output ports can be connected to an ADAT-compatible mixer to expand the number of available input channels. Alternatively, an ADAT-compatible digital recorder can be connected to an audio interface to record multiple channels of digital audio simultaneously.

One of the benefits of using ADAT is its ability to transmit multiple channels of digital audio over a single cable. This makes it a cost-effective way to expand the number of inputs and outputs on an audio interface or mixer. Additionally, because ADAT uses a fiber optic cable to transmit data, it is less susceptible to interference and noise than other digital audio interfaces that use copper cables.

In summary, ADAT is a digital audio interface standard that uses a lightpipe optical cable to transmit up to eight channels of digital audio between devices. ADAT is a popular choice for expanding the number of inputs and outputs on audio interfaces and mixers, and its ability to transmit multiple channels of audio over a single cable makes it a cost-effective option.

What’s the Catch?

While ADAT is a reliable and popular option for expanding the number of inputs on an audio interface or mixer, there are a few drawbacks to consider.

One potential drawback is that ADAT is limited to a maximum sample rate of 48 kHz. While this is suitable for most professional digital audio applications, some high-end audio interfaces and digital recorders support sample rates of up to 192 kHz. If you require a higher sample rate for your recordings, ADAT may not be the best option for you.

Another drawback is that using ADAT to expand the number of inputs on an audio interface or mixer requires additional equipment, such as an ADAT-compatible device. This can add to the cost and complexity of your setup, and may require additional cables and power sources.

Another potential issue is that using multiple ADAT devices together can introduce latency, or delay, in your audio signal. This can be especially noticeable when recording live performances, where even small amounts of latency can be noticeable and distracting.

Finally, it's important to note that ADAT is not compatible with all audio devices. Before purchasing an ADAT-compatible device, make sure that it will work with your existing audio equipment and software.

Despite these drawbacks, ADAT is still a popular and reliable option for expanding the number of inputs on an audio interface or mixer. Its ability to transmit multiple channels of digital audio over a single cable makes it a cost-effective option, and its optical interface reduces the risk of interference and noise. Ultimately, the decision to use ADAT to expand the number of inputs on your setup will depend on your specific needs and budget.

Additionally, it's important to keep in mind the limitations of certain digital audio interface standards, such as ADAT. While ADAT is a reliable and cost-effective option for expanding the number of inputs on your setup, it may not be suitable if you require a high sample rate or low latency.

Overall, the key to success when adding more inputs to your audio interface is to do your research, test your new setup before recording anything important, and choose the option that best fits your needs and budget. With the right equipment and a little bit of experimentation, you can take your recordings to the next level and achieve professional-level sound quality.
