Audient Nero Monitor Controller by Arthur Stone

Audient Nero Monitor Controller

This is the monitor controller you always wanted: better, cheaper, faster.

Wiki says:...Nero studied poetry, music, painting and sculpture. He both sang and played the cithara (a type of lyre)...Nero's devotion to music exceeded what was socially acceptable for a Roman of his class.
Typical gearslut!

Let's skip the rest of the (rather Machiavellian) biography having made the link between Roman Emperor Nero as the model for an effective controller and Audient's latest product.

Audient is a familiar name and the Nero as a product is backed-up by the company's reputation in audio engineering and electronic wizardry. Equally the Nero maintains Audient's reputation. They have really excelled here and produced an iconic product in my opinion.

Price (approx.): $349 US/ £369 UK/ Euro 380

12 month warranty; not user-serviceable.

Power supply: 12Volt DC (2 amps) Nice small 'on-plug' design that connects firmly to the unit. Accompanied by a metal Power On/Off toggle switch.

Weight: 2 kg/ 4.4 lbs Heavy enough to sit solidly on the desk but also relatively portable should the need arise.

Dimensions (w x h x d): 255 x 75 x 155mm/ approx. 10 x 3 x 5” Good, modest footprint given Nero's capability and spacious ergonomics.

Inputs: 2 pairs of TRS balanced line inputs on jack - these sources can be selected as SRC 1 and SRC 2.
One pair of TRS balanced jacks for CUE input; and AUX unbalanced inputs on RCA and/or 1/8” mini-jack. CUE and AUX also selectable. RAC inputs are overridden when the mini-jack is inserted. Neat. You can even plug your phone in.

In addition is a stereo (2-channel L/R) S/PDIF input on either TOSLINK optical or coaxial. Nero automatically locks to the source settings (from 44.1-192kHz up to 24-bit). This is high-quality and the conversion is very good. Definitely amongst the best conversion I've used; I like it.

The final input is a balanced XLR mic input (with 48V phantom-power selectable via a rear toggle switch); additionally, there is an in-built mic for talkback.

No phono/RIAA curve/grounding post input but it follows with the components logic and at this level you'll probably have specialised preamps for record decks.

Outputs: 3 pairs of stereo out to monitors – MAIN/ALT1/ALT2 - on TRS balanced jack; like the inputs these outputs are selectable (one selection only) from buttons on top panel. A rear mono sub out and 3 rear headphones out along with a front-panel console grade headphone out with a mini-jack mirror out.

The ALT outputs can be level-matched to the MAIN outs. Neat.

Functionality: There's waay too much to cover here. Put simply it's electronic control of analogue signal paths – that means recallability, presets, lower-cost, etc,

Basically you can route any of the inputs to any of the monitor outputs including 3 artist headphone outputs (with trim) and monitor the activity and routing from the engineers front-panel headphone output(s).

Usefully the Nero has a MONO button which sums the left/right channels; used with the POL button (which flips the phase/polarity of the left channel) it's possible to monitor the side signals which is useful for checking reverbs and side info using sum-and-difference. The DIM cut level can be user-defined.

Along with the CUE mix and TALKBACK facilities everything is trim adjustable and latch-able or momentary. In all a very neat package – with no sonic compromise.

The main level control – the large rotary attenuator dial – is smooth, weighted milled aluminium with a black coating. You can feel the high engineering values in your fingertips; again, a pleasure to use this easily-locatable dial. Despite the lack of detented positions, the white line on the dial can be used with the grid on the fascia for recall of level. A nice touch is that the white line is notched into the dial and can be felt with the fingertips unsighted.

Importantly the left/right channels are level-matched and I heard a balanced soundstage.

I've missed a lot out so please check the Nero manual for full details.

In Use: I'm super-fussy about what gear gets into my signal path; like many, I learnt this the hard way, but nonetheless it's a valuable lesson. I like the old BBC engineers ethos of the shortest signal path possible; in my experience this produces a full, clear sound (when the room/source are good). Dirt, broken gear, and long cables have their place too.

Out of the box, as soon as I physically held the Audient Nero, I had a positive vibe. Heavy enough; solid but portable. Robust folded-steel case; good dials with no wobble; quiet buttons; good-quality connections.

The layout is perfect for the controller task and the fascia is angled towards the user at arms reach. Great ergonomics. Nero works very well in low light.

I was a little hesitant about plugging it in; the last thing I wanted was to hear a flaw in the sonics and then have to describe that flaw to you using just words.

In the past I've used interface monitor controllers (high-end and budget); also the Mackie Big Knob Studio+, the KRK Ergo, and Audiolinear Axis (a passive desktop unit).

The Audiolinear AXIS , costing around 700 units of your currency, has been my favourite so far: I described it as “a beautiful instrument that produces silence.” In functionality, Audient's Nero is similar to the Audiolinear Axis: the major difference is that the Axis is passive (it requires no mains power input and make-up gain comes from the monitors) whereas the Nero is active. In practice, the Axis has a neutral sonic field (natural daylight as a metaphor) whereas the Nero introduces some artificial light (it's active circuitry) which diffuses and permeates the soundstage; like a photographers flash light which is only visible in the enhancement it makes to the picture.

A lot of the high-end monitor controllers are active and the Nero's sonics seem to be more similar to these than the lower-priced monitor controllers I've tried. My criticism of the lower-priced units is that although initially you get an exciting and vibrant signal, in time the sound becomes fatiguing and distortion can be discerned. In addition, reference accuracy is lost. Translation is affected.

The Audient Nero suffered from none of these issues, hence the comparison to higher-end monitor controllers. The Nero is a pleasure to use, all day and night, at any volume level. No fatigue. No noticeable colouration of sound apart from the aforementioned 'house sound' in comparison to other monitor controllers.

The Audient Nero is a flexible unit in terms of I/O connections; nothing seemed noisy or mismatched. Connected gear and levels worked perfectly and the gain trims on the Nero provided a useful range of control. I settled on connecting the last unit in my analogue 2-bus chain, a Sound Devices 702 digital recorder, into the Nero via S/PDIF at 192 kHz then into Mackie XR624 monitors.

The sound is stunning. Beautiful conversion. I have no problem using the Nero in my signal chain – analogue or digital. It works alongside, on a par with, the iZ RADAR and Sound Devices conversion.

Conclusion: Nero was a full on dude; likewise the Audient Nero desktop monitor controller offers full control with a very light sonic footprint. Faster. Better. Cheaper. The monitor controller you always wanted...
As with more expensive monitor controllers, you not only get great 'invisible' audio quality but a comprehensive routing mixer too.
My experience with the Nero left me interested in the sonic potential of Audient's consoles.

Gearslutz Score.
Sound quality: The Nero didn't adversely affect the audio – that's a big, big plus. The ambience/silence sounded 'active' (in comparison to passive monitor controllers) but very clear and lucid. The best active controller I've heard.
Ease of use: Lack of XLR out to monitor will annoy some (on the plus side it saves space and cost); the ergonomics (slight tilt), the beautiful buttons and dials make the Nero a pleasure to use even in low light.
Features: Routing; trim; meters; lit buttons, are perfect for the monitor controller task. Importantly, the volume dial is comfortable to use. Great manual and support from Audient.
Bang-for-buck: Very good. Nero doesn't mess up your sound. Well-built. Does the job without fuss. Timelessly-stylish. Good investment in your studio's signal path.

Audient Nero Monitor Controller

I had a Presonus Monitor Station V2 that I had modded by Revive Audio. New op amps and caps in the audio path as well as the power supply. I didn't have any complaints until the volume knob and the aux selector switch (as well as the headphone selector switches) started being scratchy and unreliable. De-oxit didn't seem to get in there, and after opening it up to try and deoxit the pots and switches, I somehow broke it. Anyways, long story short, I realized that the knobs and switches were crap anyways.

The Nero is the opposite in that regard-- the main volume knob as well as the smaller knobs are very solid and have no wiggle. Time will tell if they perform well for years, but they feel to be of high quality. The volume really does track accurately to both channels throughout it's range (as Audient claims). The selector buttons are also very nice, and remind me of the classic square light up buttons on SSL consoles, Otari tape machines, etc. You can hear the relays clicking as you select different speakers/sources. Nothing clicks or pops, but seems to have gentle gain ramps. Even the main big volume knob seems to have a little slight delay ramp up when you bring up the gain....I may be imagining that, I didn't test it or anything. Anyways, the result is pleasing. The feel of the main knob is great-- just enough smooth resistance. It's not detented, but prefer it not to be. It does have bold silk screened tick marks that make it easy to have set monitor gain for different applications.

The sound quality is very good. When my Revive modded Monitor Station V2 bit the dust, I rented a stock one locally while I waited for the Nero to be available in the US. I noticed a palpable difference after using the Revive modded one for so long, so props to those guys-- they do great work. So, to hear the Nero after working on the stock Presonus for a couple weeks, it just sounds completely transparent and much better in regard to stereo image. The converters sound very usable and transparent to me as well, and is one of the features I was glad it has, especially optical in. Audient claims that headphone 1's amp is "monitor grade", whereas 1-4 are loud but lower quality, and this does appear to be true-- headphone one sounds fantastic on my Audio Technica M40X's and consumer Sol Republics.

Ok, so I gave it 4 stars on features for a couple reasons-- none of which were deal breakers for me. The first being that the unit has talkback (int or ext mic) that you can route to headphone amps 2-4. It also has a "cue in" that would presumably be your headphone mix, that you can route to the headphones, and or route it to your monitors to check it/set it up. However, there is no "cue out", as in balanced L/R to go to your headphone system....I don't know why you would need talkback if you just have people in the same room with you all plugged into this unit....people like me need talkback because the players are in the other room....and I need balanced out to go into my headphone system! So the ****ty workaround is to use one of the headphone outs (unbalanced, impedance issues, etc). The second thing is the built in talkback mic really sucks. It's just crazy noisy...the presonus is way better. However, there is a mic input with selectable 48v. I plugged in a dayton omni test mic, and that sounds great. Ideally, I'd prefer to not have a mic taking up space, but I get that they had to make sacrifices to hit this excellent price point and still have the audio quality to the speakers be top notch (more important obviously). The final odd design choice is that the talkback dims the monitors, which is standard, but does not dim the headphone feed (why not make this selectable like many of the other features?). Basically they missed the mark for my use on the talkback features, but I'll still be able to deal with it.

Overall very happy with this unit.
