AEA R84

AEA R84 Ribbon Microphones

The AEA R84 is one of the large ribbon microphones produced by Californian company AEA and run by ribbon guru Wes Dooley. Ribbon microphones have always had their adherants and when they started to loose ground in the 60s as mic design began using transistors, then the ribbon mic industry went into slow decline with RCA the great American manufacturer finishing production in 1976. With original microphones exchanging hands for large sums, Wes Dooley started AEA in 1998 with the intention of bringing a range of new ribbon microphones to todays sound engineers and the AEA R84 is un-ashamedly styled on the distinctive art deco looks of the RCA 77. Based on large ribbon geometry, behind the mesh grill is a corrugated ribbon of aluminium 2.35 inches long but an amazimg 1.8 microns thick, capable of handling a massive 165dB SPL. The microphone comes in a durable and functional foam-lined case useful for storing the mic upright to prevent the ribbon sagging and includes an integral shock-mount and 10-foot captive cable. As with all ribbon mics it is a figure 8 pattern and AEA have exploited this in the design by using two layers of grill cloth on the rear side of the mic but only one on the front to create a subtle but useful character change between the front and the rear of the microphone.

Recording

Reelsound bought a pair of R84 ribbons after reading some great reviews and I realised immediately that they needed a good preamp with a lot of gain to use them effectively. I eventually settled on a Focusrite ISA 428 which has a lot of quiet, clean gain and which immediately brought the mics to life. As an aside the first Focusrite I received was part of a faulty batch (They are now made in China like everything else) and it was returned to Studiocare in Liverpool where I bought the unit. Unfortunately the replacement was part of the same batch and that one failed halfway through its first session. Studiocare were brilliant throughout and replaced this with another brand new unit which has performed perfectly over the past few months and I have grown to really like this pre amp. It is really versatile and flexible with instrument and line ins as well as the mic inputs and it really brings a class sound to some of the mics we have. Recommended..
In practice using them with the mobile for the first time I found it quite difficult setting up the R84s because they are large heavy mics and prove quite difficult to set up as a coincident pair though this is of course no fault of their own and infact AEA make a stereo version of the mic, the R88, specifically for this purpose. The first time I tried them with the mobile was with a small Brass Band in Salisbury and infact I ended up setting the mics up side by side in an ORTF-pattern directly underneath the Soundfield mic to compare the two. The difference between the two mic set ups is profound with the Ribbon mics having a completely different frequency response to the Soundfield. Initially I was really surprised by the sound of the AEAs and disappointed at their lack of brightness but back in the studio when I could hear them more clearly on my Rogers LS/35As then I began to hear where I would use the AEAs to their strengths. What at first seemed a disappointing lack of top end proved not to be a great problem as the mics take EQ very well and with a little judicious EQ I had a very smooth and pleasant stereo picture of the band without any of the harshness of the cymbals from the percussionist.
So far I have only tried the mics out as a stereo pair on this one mobile recording but I am looking forward to a string session that is coming up and I have recently bought a 3 metre lighting stand which I have adapted to make the stereo use of the mics easier. I realised that I wasn't really using the R84s to their strengths so I persuaded John Spence to take them and try them in the studio ( He didn’t need a lot of persuading it has to be said) JR

I’ve had the opportunity over the last 3 months or so to try these mics extensively during sessions at Fairview Studio with differing degrees of success. By success I mean recording a sound that has character and quality and which retains it’s tonal integrity throughout the recording and overdubbing processes, yet has enough in its frequency and spatial content to be manipulated at the mixing stage.
All too often an instrument which sounded great on its own with the just the basic backtrack can slowly disappear as more overdubs are added and when it comes to mixing you begin to wish for a bit more depth, tone and reality in the sound.

If part of the quality of a microphone is judged by its physical appearance then this is a big plus in favour of the AEAs. They never fail to impress clients when I whip off the cute little pyjama cases that come with them. The first question is usually “how old are they?”. Good looking mics!

These mics need a fair amount of gain at the pre-amp stage but I’ve had no problems using them with a Focusrite ISA 428 and a TLA Valve mic pre-amp. On loud sound sources such as drums there is also plenty of gain to be had from the studio Soundcraft 2400 desk mic amps. Having said that they are not the quietest mics for use on low level signals so care and judgement is needed at the recording stage.
If it’s accuracy of reproduction you’re after for a recording then it may be time to reach for something else, but if you are looking for some character and individuality in a sound then the AEAs can certainly bring something to the party. You only have to look at the frequency response curve in the accompanying paperwork to realise that the sound will be coloured. The question will always be “is that colouration worth having” and of course in some cases it is and in others it isn’t!

What I really like about these mics is the mid-range detail. They clearly have an accentuated low frequency response (from the specified 20hz through to around 1Khz) which can be quite “lumpy” if not treated carefully with some kind of attenuation, and the high end begins to roll off from around 2.5Khz but in a very smooth and controlled way. Fairview’s main monitors-JBL 4350s- are spec’d down to 30hz so you can actually hear all that bottom end and deal with it accordingly. Of course the low end boost is greatly affected by positioning and I’ve found that experimentation is the key. I think the advantages of using ribbon mics generally are probably that, given a good high-pass filter and the mics natural HF roll off, they leave that all-important mid-range exposed but with enough solidity to be EQ’d to sit comfortably into a mix. Of course there is more to this.

I would never judge a microphone by its published technical specification or indeed price tag but understanding its characteristics is valuable ammunition to anybody using it on a recording.
Given that these mics have a “figure of eight” pickup pattern with the negative (or generally rearward side) having a slightly increased HF response, then managing the recording environment becomes increasingly important. Obviously the distance from the sound source will determine the ratio of direct sound to reflected sound greatly, the advantage being that the reflected pickup is of good quality and in a nice sounding room can provide natural space which helps sit instruments or voices into a mix. So it’s back to experimentation.

I have recorded vocals with the R84s and positioned the singer about a foot in front of the mic and put up a screen with a blanket over it about 3-4 feet behind the mic to lessen the room “boxiness” effect.
Again careful use of a high-pass filter is needed but I tend to err on the side of caution working on the basis that I can filter out more low end at the mix if required. It’s much harder to put back in later!
I recently used them on all the guitar recordings of an album by Breathing Space. The guitarist didn’t vary his sound too much from song to song but I was able to find a distinct character for each overdub by repositioning the microphone relative to his amp. Also I recorded his Babitz acoustic guitar using an R84 and the real test is that throughout a 6 minute song that starts with solo acoustic guitar and builds to a climax which has drums, bass, double-tracked distorted guitars, Hammond organ, strings, four vocals and assorted sound f/x you can always hear the original acoustic guitar part in there without it being unnaturally loud in the mix. This track will appear on the site shortly. Also for vocal recording check out Anya Thomson’s session on this site.


I started this review by thinking I was going to say that these mics were good for some things though not for others but actually I think it’s the other way round. Some sounds bring out the best in these mics and some don’t. I like the AEAs and I will write more about them as my own experience with them accumulates)

 

With all the interest in ribbon mics over the past couple of years we eventually got hold of a pair of AEA ribbons for the studio to complement our range of quality condensers and to see what all the fuss was about. I’ve used them now on a variety of different instruments, vocals and on different sessions and I have to say I have become a massive fan. I’m currently 7 weeks into an album session with the band Mostly Autumn www.mostlyautumn.com and this has given me the opportunity to experiment and compare the ribbons against our favourite studio mics.
Mostly Autumn’s music ranges from acoustic tracks with guitars, pipes, whistles, bodrahn and assorted percussion to songs featuring drums, bass, guitars, keyboards, Hammond C3, stacked vocals and the kitchen sink!. Recording all this stuff is easy but balancing and mixing it is somewhat trickier and you have to take special care when laying tracks not to get a build-up of frequencies in the same sonic area.
The AEA ribbon mics have been invaluable in this respect and you can accurately tune what high-end there is by tilting the mic in the vertical plane aginst the sound source. I’ve regularly put up an AEA ribbon, a Neumann U47 and a Neumann U87 to compare and many times chosen the AEA based on its perceived warmth and lack of “peakiness”.
On some instruments the ribbons are stunning and acoustic guitars, flute, Uilleann pipes and tin whistles all benefit from the beautiful smooth top end that the mics impart.
Pipes and whistles on the session were played by Troy Donockley, (Iona, Barbara Dickson, Maddy Prior) and whilst Troy is an excellent player I’ve always had problems dealing with the very bright, peaky sound of the instruments, trying to control certain frequencies without over-using compression. Positioned about two feet away from the pipes and directly in front of the seated player the sound was wonderfully smooth and rich. Running the mics through a Focusrite isa428 pre and and into a very old Audio Design compressor the sound was totally sorted. Against this setup the U87 sounded thin and reedy and the U47 was only a little better than that. No contest really.
The only other action I took was to drape a heavy blanket between two mic stands about three feet behind the microphone to deaden the back side slightly and eventually I took the Neumanns down after listening to the whistles in order to get Troy nearer to the ribbon mic.
With minimal compression and recorded direct to the Radar system with no eq at all these overdubs sound stunningly real and people who visit the session are being very complimentary about the monitor mixes they are hearing.
But before we get carried away and to illustrate the point we make about there being no “perfect” mic for everything let me tell you that I used an AEA ribbon on Mostly Autumn’s female singer Heather Findlay and it sounded fantastic. Loads of real mid-range body and just enough presence in exactly the right area. The same mic used on the male singer, Bryan Josh did him no favours at all and I ended up using a cheap Joe Meek condenser costing a tenth of the AEA and it sounded wonderful!.
If I have to try and sum up my experiences with the AEA ribbon mics based on extensive usage over the last year or so and my instinct right now is this.
If someone said “you can choose three mics to make an album with-what are they?” then an AEA ribbon would definitely be in there!
One of the others would probably be a ’57 and I’m not at all sure what the third would be but I’m working on it.
