THE COMPRESSOR
The compressor is available in all programs, except
Dynamics. (Dynamics uses a different compression
mechanism, explained on page 4-33.) The compressor
sits in the wet component of the signal in front of the
effects in the loaded program. It is controlled with four
parameters: CmpRatio, Threshld, CmpAttk, and
CmpRels. These parameters are located on the last Edit
Page for each program, except those in the Cmprssr
Bank.
The ratio (CmpRatio) parameter can be set to ratios of
1:1 (off), 2:1, 3:1, 4:1, 5:1, and 10:1. The threshold
(Threshld) parameter can be set within a 0 to -32dB
range. These settings are relative to 0dBFS (digital
saturation). The compressor is disabled if either the ratio
parameter is set to 1:1 or the threshold parameter is set
high enough to prevent the incoming signal from
crossing the compression threshold.
The attack (CmpAttk) and release (CmpRels) parameters
determine how fast the compressor responds, within
3dB of the output level dictated by the incoming signal.
For most music material, the release time should be
about four times longer than the attack time. Both must
be long enough to accommodate the bass content of the
music.
If the compressor is set to react faster than the waveform
of the music itself, the resulting changes in output level
will re-shape the waveform enough to produce
undesirable audio effects. For example, 80Hz has a
period of 12ms. If this is a dominant component in the
music, set both the attack and release parameters to at
least 12ms, even higher for better results. The
compressor acts on both the left and right channels at
the same time, using the sum of the two channels as its
trigger.
Compression presets are available in the Cmprssr Bank
(see page 4-31). For other compression-only effects,
send compressor output into a Dly/Eko program with
the Delay parameter set to 0. The compressor does not
add propagation delay to the audio path. (Note the
converters introduce about 2ms of propagation delay.)

CMPRSSR
In all Cmprssr programs, the "Adjust" parameter controls
gain within a range of 0 to 9.5dB. It can be used to
match volume levels between the dry, bypassed, and
compressed output obtained with typical music
material.
If the System Mode parameter Mix Mode is set to
Program, the Mix parameter will automatically be set to
Wet, allowing the compressed delay signal to be the only
output signal present. If the System Mode parameter
Mix Mode is set to Global, the Mix parameter must be
set manually.
The five compressor-reverb presets offer a reverb
component in parallel with a zero-delay dry component.
The compressor acts on both. The Mix parameter should
be set to Wet, and the effective mix should be adjusted
with the Efx Bal parameter.

Might be getting one to replace a Microverb4 Im considering using them both and using one for vocals only. I know what the verb4 does but never used the 550. Which one would you put on the mics? Also the way I would hook it up is directly out of the compressor....

Do you not have a mixer with Aux send/returns? Just curious as to why you would run the effects inline with the mic - you would only be able to effect 1 mic (with the particular effect). The MPX550 (I am assuming) is a great little unit. Very programmable - kind of confusing in some of the parameters. It has been discontinued, not sure for which model replaced it. I would use both processors for vocals if my mixer could handle both - but that just me :D

Yup using a DFX12 thats how the verb4 is routed. I would rather do it that way on the vocal then you still have a wet and dry input and easier to control.. Just mulling some things over Ive always wanted have separate vocal FX even if only on mic1.. I thing the MX300 is the one that replaced it and think I would rather have it for it also has a usb connect..

The MX 300 did not replace the MPX 550, the little MX 300 is only a single engine processor. If i were you and going to get a Lexicon i would get the new MX400. It is a fantastic unit, and a very good choice. It is USB compatable. Also, i would look at the TC Electronics M350 processor for around $200, it's also puter compatable for recording software. I bought a little t. c. Electronics M350. Easy to use right out of the box, and it sounds great, and is whisper quiet, and you save a few bucks.

Yea I think so Itll run circles around the verb4 I downloaded the manual and skimmed thru!!! Its gonna take me a year to learn how to run it and learn all the features LOL I think I will modify the old dfx12 again and separate the fx2 sends on mic1 & 2 from the rest of the bus to proc the mics only maybe return to aux2 return. I got in the new slider from Mackie but it hasnt cut out for 2 or 3 weeks. I might just go ahead and change it out anyway. When I do Ill take some photos and give a short tutorial on the mod and slider change.

Quote: Sounds great karyoker...it will be great to watch someone else work for a change. Then when you're done, since you're a pro. I will just let you change a couple out on my old Carvin board. Man i just couldn't keep sliders in that board. And i have always cleaned them, and use CaiLube which did make'em last a little longer. They are 60MM Panasonic sliders. But man they sure didn't hold up to the test. I never had that trouble with Mackie or any other board i've owned. I use it for a back up board. As an old tv tech and broadcast eng I still like tuner cleaner prob not as good as cailube... shacks Im not familiar with those sliders although you could find a Bourns or a real one I used to know the manus that met military specs (expensive)here that would stand up better than most. Ive actually redrilled the ckt brd for the difference in leg placement And hard wired. I used to charge immense of amounts of money for knowledge like this but Charmin and Babs and others have me totally whipped and I totally confess.. Is the dust cover slots that the slider arms slide thru still tight? Actually compact audio mixers are fairly simple Ive worked on huge video and audio switchers in tv studios. Well I havnt worked on the grass valley 3200 I have worked on the 1200 all video inputs have to be synced with time delays and balanced with respective audios. The overall gain from black to highest shades of gray are critical then we will consider color. The video and audio levels in this desk has to be precise If you will notice there are Tektronix 528 scopes above to constantly monitor levels..

Actually after reading the manual I am going to replace the DBX 266xl with the lexicon 550 It has a builtin compressor. Here are a couple of pages from the manual The dynamics they refer to are studio only (audio expansion etc) and the compressor even has a few presets which apply reverb of course others can be applied and stored into a program.. There is a mix (wet/dry) ratio on all in global which would work with the insert mode but I an debating using the sends to have a quick adjustment wet'dry on the mixer.

Quote: You can send me your old one Very Happy No kidding I think about the only knob I ever turned on it was the output gain!! And sit there and watch the red lights that told me how much it was doing I aimed for 2 or 3 lights blinking with loud singers but after while it didnt bother me if half a dozen or more were blinking part of the time.

Got in today when I plugged it it in ( replaced the verb 4)it was on small plate since I like plate on country music I called up Jim reeves Blue side of lonesome It was awesome And this was only one!!!

Karyoker..trust me, yur gonna love that 550......Just glansing through that manual page. It looks like what we use to refer to years ago as "Soft & "Hard" knee compression. I'm sure with the release times given, it's similar. Being from the old school i know you are familar with that. They are great units.

Post subject:	Re: Lexicon 550
Will use it sat night. I have it in the insert mode with mic 1 & 2 And input in dual stereo. With the mix at full wet it doesnt overdo it. It puts a very subtle touch on it. Im going to try chorus reverb, male vocal (delay & reverb), female vocal, and vocal plate. I have these programmed in user bank 1-16 On all the compressor ratio 3:1 thresh at -5 db.. All Ive heard it is headphones with dj music Will what does for vocals at the gig....

It is AWESOME... Unless the singer is one of your regs and you know how they sound on certain songs you really dont think its doing anything. But if you leave it on female vocal and a male starts singing then everybody including the singer is wondering whats going on cuz something aint right...One has to be far enough from the singer or FOH in front of a main to adjust the mix (wet/dry)... This is a system that to be fully utilized should have a separate sound man...It could be the best addition to this system yet..
