How to Choose the 4 Channel Audio Interface?

how to choose the best 4 channel audio interface

Mic Level, Instrument Level, and Line Level Inputs

While the overall number of channels is very important, you also have to know the type of inputs included on the line level (low impedance) and instrument level (high impedance) of the audio interface. The latter is there for electric and bass guitars that don’t have an active preamplifier. Meanwhile, line-level inputs allow you to connect keyboards, amplifiers, and other instruments. XLR ports are typically paired with preamplifiers that allow using mics. Mixed XLR/TRS inputs come with embedded preamps, meaning they arrive microphone-ready. Finally, select audio interfaces allow you to switch between high and low impedance inputs for specific ports.

Preamp and Phantom Power

Integrated preamplifiers enable you to use mics and can supply power to condenser microphones when required. In addition to their connectivity purpose, preamps can change the nature of the sound and help keep noise at a minimum. Companies rarely save costs on preamp quality, typically adding the preamplifier included in their flagship audio interface to all their products. Keep in mind that not all ports come with a preamplifier so check the number of included preamps when choosing the best 4-channel audio interface, especially if you plan to record sound using condenser microphones.

Power Options

As the number of channels gets bigger, the circuit included in the audio interface as well as its complexity gets larger too. That’s why most models featured in this overview can only function with a wall power adapter. That said, there are still some audio interfaces that can receive power by being connected to your PC or laptop via USB, but even those models won’t let you use an iOS device for this purpose, meaning you’ll have to rely on the provided power adapter.

Analog to Digital Bit Rate and Sample Rate

This characteristic is defined by the resolution of the converted digital sound. Typically, the larger the sample rate, the more detailed the audio. Nowadays, the premium industry standard is 24bit/192kHz but users tend to often have a different opinion when discussing the optimal sample rate for their setup. If you’d like to learn more about this subject before choosing the best 4-channel audio interface, watch the Science of Sample Rates. The main thing you have to remember is that a 44.1kHz sample rate is high enough to encompass all hearable frequencies. It’s also worth noting that preamplifiers typically have a larger impact on the recording quality than the sample rate on its own.
