Thoughts on the Focusrite VRM box…..

Focusrite VRM Box: What EXACTLY does it do?
focusrite vrm

OK, the VRM Box from Focusrite has been available since Spring of 2011, and even earlier if you include its incorporation into the Sapphire Pro 24 DSP, and many people have asked me a) What it is and b) what does it do…

So here’s my answer…

First, I own one of these.
I bought it,
with money.

Second, you need a decent pair of headphones. (But you should have these anyway..)

Third, Its a fairly simple idea, that gets lost in translation.

In the old days of home studio recording, you would run happily between Hi-Fi, Car stereo, Beat box etc playing your brand new mix, trying to see if it sounded equally good on all.
The idea being of course, that ideally the mix would sound brilliant on everything.
The reality was somewhat different. Each system you played it on brought its own colour and eq to the party, and you invariably ended up more confused than when you started.

So to the Focusrite VRM box.
A virtual way of doing the same thing, without leaving the studio.
The Focusrite VRM box simulates the sound of your mix, as it would be heard through 13 different types of reference monitor, including Japanese White Classic (an NS-10 algorithm), KRK Rokit6 and VXT8 models, Auratone, American Passive, British Studio, Genelec 1031A, plus Adam S2.5A and Rogers and Stirling LS3-5A monitors and in a choice of 3 different rooms, bedroom, living room, studio control room.

Thats it.

for £79.00.

Only thats not just it.

You see, its REEALLY useful…..

Lets try and understand exactly why.

First off, the whole idea of mixing / mastering is hugely subjective.
(As a side note here, its long been said that Mastering in your own studio is like home dentistry, the whole idea of taking your stuff to a professional mastering engineer is to allow an impartial professional pair of ears, with massive investment in gear designed solely for the task at hand, to alter your sound to fit the most amount of environments..)

Thats the reason there are so many different types of reference monitors on the market.
Some people just prefer the sound of one to another.

I personally still rely on an old original pair of Mackie HR824’s.
I know I’d love a pair of Adam A77x’s, but I dont need them, my stuff is broadcast on TV, Radio and in Cinemas, It’s mixed in my basement studio.

So what is the use of the Focusrite VRM box…… ?

Simply this…..

It will never hurt for you to hear your track in different circumstances. Just the lifting of a Bass section can show how well or not it works with aa Keyboard part, just aboost to a string line can reveal clashes that didnt seem apparent before….

Here’s something else thats cool……

Take a well mastered album or song you know well…   I mean REALLY well.

Play it through your headphones using the Focusrite VRM box, and pick a room setting and 3 speaker settings.

Listen to what it does to the reference track.

First of all this is fun. It brings out all sorts of things you’re not used to hearing, and that’s a good thing.

So, listen hard to the track……

Write notes.

Does the reference track lose or gain anything when listening to the familiar track?

Now play your own mix.

Listen to how it compares.

If the same Focusrite VRM settings are having the same sort of effect on your mix, you can be reasonably sure you’re in pretty good shape. If however, the different speaker settings are giving wildly different results, you may need to start moulding your finished mix to suit.

To recap, if you play a properly mastered album through the Focusrite VRM box settings, you should still be able to hear all the constituent parts, albeit some may be louder or quieter than you expect. If your track starts to lose bass lines or you develop a hump in the mid range, it may be time to look at a different set of reference monitors.

New Focusrite VRM Monitoring Guide

Last year one of the more interesting peices of kit released into the market place was called simply the Focusrite VRM Box where the VRM stands for “Virtual Reference Monitoring”.

We like this solution as it goes some way towards helping you carry out that age old ideal of testing your mix on as many reference systems as possible without having to record a copy off each time. The VRM box does this by emulating a selection of classic speakers and room modes so that you can audition your music in various situations without ever leaving the comfort of your studio chair. If you were to go out and purchase all of the speakers emulated to set them up in your own studio then the chances are you’d be out of room and money before completing such a project so this techknowledgy offers some great benefits that you simply wouldn’t be able to recreate with any real ease in the real world.

The Science of VRM

The Problem

Accurate mixing has until now, required expensive monitors and a carefully designed and treated control room. Currently, both professional music producers facing budgetary limitations and project music makers without access to such, frequently encounter mixing and “auditioning” difficulties.

The Solution
The Focusrite VRM Box solution allows you to choose from 10 pairs of industry standard nearfield and main monitors in an acoustically treated control room. Engineers routinely A/B their mixes by burning CDs and taking them into untreated rooms to reference on consumer stereos. The Focusrite VRM box eliminates this process by simulating two extra rooms; a large living room and a smaller bedroom. You can choose between a range of speakers including quality hi-fi, computer, cheap stereo and television speakers.

The Method
The Focusrite VRM Box uses standard headphones to reproduce the direct sound, together with software running on your computer that is used to simulate specific monitoring scenarios. VRM’s room models are mathematical models which provide greater flexibility in the possible combinations of loudspeakers. The loudspeaker simulations are created using convolutions of impulse responses measured using the original loudspeakers. The accuracy of these simulations in different environments is taken care of by the impulse responses themselves and the way they are calculated and manipulated.
