Name: Rode NT-USB Mini USB microphone
Price (RRP): $149
Manufacturer: Rode Microphones

For obvious reasons, we like to highlight Australian brands here at Especially when they’re as prominent in a field as Rode Microphones is in its. The company is one of the world’s leading developers of quality microphones. And its newest microphone is an affordable model for podcasters, and others who want quality. The Rode NT-USB Mini is priced at less than $150.

And check the end of this review. You may be able to win one of these microphones from Rode (closes 6 March 2020). (BTW, the name Rode uses is “Røde”, but we’ll just run with the simpler form of the name.)

UPDATE (a short time later): I kind of assumed that while designed in Australia, the microphone would have been made in China. But I’ve just looked at the bottom of the box and it turns out that Rode manufactured the microphone here.

Rode NT-USB Mini features

The Rode NT-USB Mini is a studio-style microphone, but with a built-in digital interface. It is designed chiefly for plugging into a USB slot on a computer. The digital standards are absolutely standard. It operates at 48kHz sampling and 24 bits of resolution. Accordingly, it’s compatible with just about any computer out there.

Being studio style, it’s a side-address microphone. You don’t speak into the end of it but at its face. Or perhaps across its face, according to your style and preference. It’s quite small. The microphone part is roughly a rectangular prism measuring 52mm wide, 100mm tall and 42mm deep. This is mounted into a U-bracket in which it can swivel freely, but with sufficient friction to maintain its position. At the bottom of the U-Bracket is a hole threaded ready for a standard microphone mount. It’s provided with an adaptor for the smaller threads used on some mounts.

But chances are you won’t use those because the Rode NT-USB Mini comes with its own stand. A rubbery insert in the standard mount hole is pre-installed, and this mates with the upper protrusion on the included desktop stand. A fairly strong magnet in the base keeps the microphone in place on the stand, yet able to removed with a simple tug.

As it happens, the importance of this magnet was proved by the first review sample that was provided. Somehow the magnet had been left out in manufacture, and the microphone stood on the stand only uncertainly, and easily toppled when the microphone was tilted. The replacement with the proper magnet in place worked perfectly.

Inside the Rode NT-USB Mini microphone

Inside the Rode NT-USB Mini microphone is an electret condenser microphone capsule, an analogue-to-digital converter with USB interface and a digital to analogue converter along with a headphone amplifier. There are no batteries. The unit is powered via its USB connection to computer or other device.

On the back is the USB connection – it uses USB Type-C. That’s welcome. The faster we move to the USB Type-C plugs and socket the better, although the higher speed isn’t needed in this application. Also on the back is a 3.5mm headphone output. This proved perfectly capable of driving my 80-ish ohm impedance headphones, along with lower impedance models. In an application like this you’d typically choose closed-back headphones for good sound isolation.

On the front – that’s the side that also picks up your voice – is a level control knob which doubles as a push button. This control is for controlling not recording level, but playback level for the headphones plugged into the unit. In normal position, the sound the headphone output delivers is that provided by your computer. Press it, and the sound from the microphone is routed directly to the headphones. This eliminates latency. Converting the analogue signal from the microphone to digital, sending it to the computer, waiting for the computer to do whatever with it, receiving the digital sound back from the computer and converting it to analogue … all of that takes time. There are plenty of situations in which you want to hear what the microphone hears without dozens of milliseconds of delay.

Even when delivering a direct feed from the microphone, the headphone output still also delivers any audio being provided by the computer. So you should switch off the monitoring function, if any, of your digital audio workstation.

Rode NT-USB Mini recording levels

So, how does one set the recording levels in the absence of a hardware control? You do that in either your recording software – if it has that control – or with your device’s operating system input level control. For those interested in such intricacies, I should make it clear that you install no drivers for the Rode NT-USB Mini microphone. That means no ASIO on Windows. ASIO isn’t really required because the microphone doesn’t attempt challenging high resolution sampling frequencies. The microphone DAC runs at a fixed 48kHz sampling and 24 bits of resolution. Some high-resolution enthusiasts may complain, but that’s a solid setting for high quality audio. In particular, the 24 bits of resolution allows one to leave a little more headroom in play then when using 16 bits.

So you use standard Core Audio on Macs or Direct Sound or WASAPI in Windows to handle the sound. If you are using recording software without a built-in recording level control – for example, Reaper or my ancient favourite, CoolEdit 2000 – then you may use the level control in Core Audio or Windows.

In Windows, that means delving into the creaky Windows audio interface to set the level. That’s not the easiest thing to find. One way: right click on the speaker icon in the system tray, click “Open Sound settings”, scroll down to “Input”, click “Device properties” and you’ll have a panel with a level slider on it.

Do you need to set the level?

If you’re using high-end audio production software like Reaper, you don’t really need to set the recording level. You adjust the relative levels of the tracks when mixing. If you’re using something simpler to capture the audio and don’t really plan mixing, then you may want to fine tune using the OS level control mentioned above.
