Hello! I was wondering if anyone could recommend or knew of a single or combination of 1U rack mount units that would allow me to split my signal into a at least 2 channels (High and low) with an adjustable crossover point, then recombine at least those 2 channels before sending to my power amp? Also if anyone can recommend a solid 3 channel compressor that has separate controls for each channel, that would be awesome. I'm not afraid of too many knobs! The goal here is to use a nice multi channel rack mount compressor as a multi band compressor with the aid of the crossover/splitter and mixer/summing unit. Thanks! Max
I've yet to find a multiband compressor that offers the adjustability that I'd like. That being said, I'm open to suggestions. I was eyeing the BECOS Twain, but at $370 and a bit large on the pedal board, combining a rackmount crossover, rackmount compressor, and rackmount or pocket sized mixer seems reasonable. So far I've found the following: Mixers to recombine: Behringer Micromix MX400 Line Mixer ART SPLITMix4 Passive 4-channel Mixer / Splitter Nady RMX-6 Rackmount 6-Channel Microphone / Line Mixer | Crown Music | Reverb ART - Applied Research & Technology PowerMix 1 - 4 Channel Passive Mixer - Used | Guitar Hangar | Reverb Nady MM-141 4-Channel Mini Mixer | Delta Roots Used Instruments | Reverb Crossovers: DBX 223xs Stereo 2-Way/Mono 3-Way Crossover Rackmount (LOOK) | eBay Peavey PV Series PV23XO Precision 2/3 Way Crossover | Bill's Music | Reverb ART Model 310 Stereo 2-way / Mono 3-Way Electronic Crossover | Toms Sound / Birmingham AL | Reverb dbx 223s Stereo 2-Way/Mono 3-Way Crossover | Reverb Compressors: DBX 1046 Rackmount Quad Compressor | BinghamTone | Reverb dbx 166A 2-Channel Compressor/Limiter | Reverb Alesis 3630 Dual-Channel Compressor / Limiter with Gate | 1220 Music | Reverb I really like the look of the Alesis 3630, as it has all of the adjustments that I'd like to have, however I wish it were a three band so I could make the most use of the typical 3-way crossovers. Something like this would be sweet, minus the $1700 price tag: Drawmer Electronics - 1973 Three Band Stereo FET Compressor
Track down a Rane DC-24. They’re no longer made but are usually available on the used market. They’re very high quality and pretty flexible.
I have 2 very versatile units in my rack that I sometimes used this way. A Behringer Ultragraph Pro FBQ1502HD that comes with a built-in crossover. A Behringer MDX4600 which is essentially 4 compressors in a single rack space. You patch the outputs from the crossover into 2 of the compressors and back to the mixer or straight to the power amp. Not high end gear at all but 2 well working units that thanks to the rise of digital mixers can be bought for next to nothing these days.
Woah those look awesome. I'm trying to read the manuals but for whatever reason they're always a bit jarbled. Does the 4 channel compressor have the following controls on each channel? Attack time Release time Threshold Ratio Input level Output level Also that graphic EQ with built in crossover, does it act as a two-band or a three band? All this being said, I'm still considering the BECOS Twain because such a rackmount system might be a bit... How do you say. Clunky?
Just won an auction on a Peavy 3/4 rackmount crossover. It is a stereo 3 or mono 4 way crossover. Now I just need to decide if I go with a 4 channel compressor, or do I stack two 2-channel compressors. I'd like to go with a single 4 channel, IF it has all the controls I'd like to have. So the Rane does look good, but between it being around $200 or so, the proprietary power supply, the fact that it is only two band, and the fact that the compressor controls themselves don't have the full tweakability that I'd like to experiment with, I think I'm going to go with a multi unit setup.
Might be hard to find because they haven't been made for a while, but what you are describing is the Drawmer THREE-SUM.
So I've got the Peavy XD 3/4 1U crossover coming. It can do two channels of 3 way crossover, or mono 4 way. Also got a dbx 166XL dual band compressor coming. I'm probably going to pick up another 1U dual band compressor, or possibly the Behringer MDX 4600 4 channel. I'd prefer to have a single 1U 4 band compressor, but I don't see many options for that, and the reviews of the MDX 4600 don't look great, plus it doesn't have individual threshold, ratio, attack, and release controls for each channel, which is one of the main goals of this setup. I'm probably going to pick up this mixer: https://www.guitarcenter.com/Nady/MM-242-4-Channel-Mini-Mixer-1274034485907.gc Or maybe this one: https://www.guitarcenter.com/Behringer/MICROMIX-MX400-4-Channel-Line-Mixer-1274115050370.gc Or maybe this guy: https://www.guitarcenter.com/Used/Shure/SCM268-Unpowered-Mixer-117143216.gc?rNtt=shure mixer&index=3
Just out of curiosity, since this is posted in the recording gear forum, is this intended to be used as part of the signal path when tracking or for mixing? If the latter, what are you using for a DA and secondary AD to push it back into the box?
This is meant for live application. I only posted it here hoping that the recording gear guys might have a broader base of knowledge with regards to rack mount gear.
