I am thinking about adding another compressor to my collection and I
started thinking about the Apex line.

Geez, Expressor, Compellor, Dominator, it's hard to keep them all
straight. I've heard some of them totally suck and that others are
really cool. Then there is one that supposedly sucks until Jim
Williams mods it, then it's really cool.

Other than staying away from anything that says "Tubessence", can
anybody suggest what the Aphex comps to look for are?

I know the Dominator is more aimed at broadcast apps, but what's the
diff between an expressor and compellor?

Thanks,

Analogeezer

The Expressor is their "real" compressor, with the ratio, thresh, attack,
release controls. It's got a hi freq expander (HFX) that boosts treble at a a
selected freq and ratio as the compressor vca attenuates, to compenste for high
end lost from compression. There's also a Lo Cut filter in the sidchain that can
be a handy feature. They track fairly well in stereo, but controls on both units
need to be matched (though there may be a way around that using sidechain
inserts, summing the detector signal, in master/slave mode, blah, blah, blah....
I never tried it...just thought about it in bed one night). It's a good, clean
sounding, useful unit. The "Tubessence" (eeew, that term...whenever I see it, I
hear it in my head with a lisp.) model has the addition of an Auto timing
circuit, but I don't know if it's worth going through that deprived tube for.


The Compellor is a slow compressor combined with an even slower leveler (gain
riding), with next to zero (compression) tweakability. I've always thought it
to be more of a broadcast tool to keep overall program levels consistent, though
I know many use it for recording and mixing.

I have the Dominator which I use only when mixing. I just strap it across the
mix bus and hit it very very lightly to prevent overs. Its the only limiter
I've ever used regularly in this app so I have nothing else to compare it to
but I think it sounds pretty transparent and does a good job with any peaks
that hit it. It's not a unit that you would use to color the sound
deliberately. Its a peak limiter only. There are two models: the 720 which is
the standard model and the 722 which has pre-emphasis for broadcast use.
The Compellor is their compressor and is suggested for use with the Dominator.
I have never used a Compellor but I've heard good things about it. Again, I
think it tends toward transparency, not color.

I have some Expressors here. A string bass player brought over his Jim Williams
modded Expressor & we compared the same passage through each. It's pretty
subtle. The modded unit had ever so slightly less low end, but there wasn't
enough detail-y kind of stuff on the bass to really hear what may have been
different in the mids or high end. The Williams mod may possibly have felt a
little more hi-fi but I'd need to hear some drums & cymbals to make that
opinion. The stock version doesn't suck, though it's no 1176. It's a clean VCA
compressor that does all right, especially for around $200 used.

<<I know the Dominator is more aimed at broadcast apps, but what's the

A Compellor is a leveler. Set a target output level & your meters go up to
there & stay there, though you won't perceive it as being dynamically altered
much. It's very transparent, doesn't sound squashed, but totally doesn't work
as a compressor ought to on individual tracks. Use an Expressor for that. The
Expressor has the usual VCA controls for attack, release, ratio, make up gain,
input level, etc. The Compellor gives you the most basic of controls & they all
operate fairly nonintuitively. It's pretty much a set once & forget device that
does one thing really well. Chances are you want the Expressor for most day to
day audio work.

I like my 661 Expressor, you can really squash stuff if you need to, yet it
remains very transparent. Definitely worth a look.

I've used the Compellor to send live and pre-recorded feeds to ceiling
distribution systems, and for that it's great. Handles a tremendous dynamic
range, and it's (almost) idiot proof . I believe its use in the studio is
extremely limited.

I really disagree regarding the Compellor in the studio. It is VERY useful,
but it's really a different bird altogether. It's not like any other
processor. I use it mainly for the 2-buss. It's extremely uncolored, and
useful when you want to really flatten the dynamic range on a mix without
really making it obvious. When I want 2-mix transparancy, I break out the
Compellor. When I want 2-mix glue, I use the Smart. It's nice to have both.
But if you're looking for single channel compression, you may want to look
elsewhere.

The Dominator (Dominatrix?) is just a nice limiter to use as the last
processor in the mix chain. Helps me to get hotter mixes to tape.

BTW for some good references, do a google search.

Y'know, the Jim Williams mod is weird to me, in the sense that it makes it
slightly more hi-fi and/or high quality, as you imply, but that to me isn't the
shortcoming of the unit (not that it's so hi-fi). I've got a pair (well, in
the closet) The first compressors that I actually went out and bought a pair
of, as opposed to using what belonged to the studio (probably the best buy in an
inexpensive quality pair at the time), and while their lack of coloration makes
them good for that role, I always had the feeling that if someone would mod them
to give them some real personality they could make some dough. Now that we all
record to disk and use plug-ins to keep levels safe once inside, who among us
could not use another box to make the sound bloom before it hits the platters??
I know you can't turn it into a Distressor with a few extra parts, but I'd pay
for someone to turn it into something that barks instead of acts transparently.


I know JW does a bunch of other improvements to it (power supply, etc) and it's
a quality mod, but Jim's thing seems to be to clean things up, which isn't what
I'd want out of an Aphex Expressor mod.

Anyone know of someone who mods them into not-transparent, beefy squashers?

I have a pair of the 651 Expressors (non-tube). They do well for
fairly clean compression, especially for vocals with wide dynamics
that need to be tamed. It can be hit hard with -20 dB of compression
with way less artifacts than, say, a dbx 160X. Nice utility
compressor for the money.

The rep of Aphex stuff is based on good sounding VCA's, which are very
transparent. You're thinking about adding another compressor, is it for a
specific appplication? The units you mention all do different things.

The Compellor is more of a leveling device than a compressor as most people
think of compressors. It actually brings up low level program towards where
you want it to be rather than merely squashing down loud levels and then adding
gain. And the way it responds to program isn't like a lot of compressors
either, where at a certain bass frequency point the compressor reacts
more(typical DBX thing), it's more evenly tuned, and sometimes it seems the
middle range of what you send it comes out just a tad more "forward" sounding
than it went in. If you wish to squash the dynamic range of acoustic or
classical music for broadcasting a Compellor is a pretty nice way to do it.
Film guys love to run dialog through them, and I have worked in broadcast
joints where the studio/gear combos sounded way bad until a compellor was put
on the 2 mix. Great for applications where other kinds of dynamics devices
have too many drawbacks. I like them.

The Dominator is a brick wall limiter. I have seen them used in
Cablecasting to prevent overs in audio transmission, in PA applications to
prevent people from blowing up a PA system and in studios (covertly inserted
inline) to prevent clients who love certain bass heavy material from blowing up
the good monitors. I would probably feel better about an in-ear monitor system
knowing there was a Dominator between the program source and my ears.

Never used an Expressor.

Not so. The Compellor is just so fucking transparent that you can't hear it
unless you push the crap out of it.

Want artifacts? get a DBX (or many other makes) Don't want to know it's
there, try a Compellor.

I like it a lot in the studio on the stereo buss... brings up average levels
without mucking anything else up and it's pretty transparent in the process.
Also handy just for automated gain riding, when you don't have enough hands.
But it's definitely not something you can use as an effect.

What's the difference between a compellor and a compellor?
Keep in mind there are a few flavours. The older ones are stereo
only while the newer 320s are also dual mono. I have one of the original
ones. Very nice, but I wish I could also use it dual mono.

I still haven't managed to find a manual. Plus, mine isn't even a

Yes... get the patent. It's freely available from the uspto patent
server and it's a very enlightening read. There's basically a control
in there to adjust the operating point of the device and they set it
for a given distortion level.

Thanks. Good thread. Of the products I've used, I agree with most of the
assessments. Compellor is pretty good and quite transparent across the 2
bus unless you simply are looking for a fucked up sound. Expressor does a
fairly good job taming some tracks that could use a little umph without
going overboard. As always, nothing serves every scenario, and if dollars
aren't a problem for a little more, you shouldn't have too much of a problem
with either one.

As always, fun to see Jim Williams is still paying attention. I'd thought
we lost him 6 months ago! <g>

Oh, yeah... Compellor on the drum overheads. Doesn't give you a huge drum
sound. Doesn't exaggerate the reverb tail. Doesn't make things more
punchy. But it does smooth out the sound of a drummer who doesn't hit
consistently, without doing anything to the overall tone.

I tend not to use the leveler side much (not that I've put in much time to find

Depends on whether it helps any. I find it's handy for levels that change
slowly.

It's a thing for levels that change gradually over time. It's like a little
guy inside with his hand on a level control, and basically is there to replace
manual gainriding.

I remember one AES show (pre Javitts Center days) when Aphex had the
Compellor, Exciter, and Dominator on display and they were handing out
buttons and T-shirts which said "Compel, Excite, Dominate." Laurel
Cash (Jones), a media person who's quite the babe walked out of the
show on a warm evening wearing one of those Aphex T-shirts and ducked
into a hotel bathroom to change shirts after realizing why she was
geting more than the usual amount of stares.
