Hardware Warm Audio introduces BUS-COMP - Stereo Bus Compressor

Warm Audio introduces BUS-COMP - Stereo Bus Compressor-screenshot-2020-01-01-11.55.57.jpg

The Warm Audio BUS-COMP is an all-analog, 2 channel, stereo VCA compressor based on classic circuitry that has provided silky smooth tone for decades. Stereo VCA compressors are masterful at controlling dynamics on many sources, but they have become widely known for their magic touch on stereo mixes.

The BUS-COMP will perform well on stereo mixes, drum mixes, drum overheads, acoustic guitars, keyboards, piano, orchestral instruments, voice-overs and an array of other sources. The BUS-COMP is primarily designed for stereo use, but it can be used just as successfully on individual mono sources. VCA compressors of this type have become widely loved for their ability to control dynamics effortlessly but also for the added tone and depth they provide to the audio signal that passes through them, even when no compression is applied.

A Look Inside
Re-creating legendary VCA compressor technology was the focus of the BUS-COMP’s design, however, adding options and improvements was just as important to us during its development. One feature we are proud to boast is the BUS-COMP’s ability to have USA made CineMag transformers inserted into the signal path driven by fully discrete operational amplifiers. With a single push of a front panel switch, these custom USA made transformers are inserted into the audio’s path providing increased depth, tone and vibe!

Premium Components
As with all of the products we develop here at Warm Audio, the BUS-COMP was designed with a price point in mind. With efficient, modern manufacturing techniques we are proud to bring this boutique quality, classic VCA compressor to the market at a quality-to-price ratio previously unseen. More studios than ever before will now have access to analog quality VCA compression. Our desire is for all musicians to be heard the way they want to be heard and we feel the BUS-COMP is the perfect tool to perfect any mix!

I had a feeling this would be on the way! Looks like they took some inspiration from TK audio with the transformer option.

Looks very nice... I’m satisfied with my TK BC1, but the price on this is tempting. Wish it had wet/dry, but not a deal breaker.

Looks a bit like the SSL 4000 G Compressor.
Would be great if it sound like this one for that price.
Hopfully somone check it out this month!

It has a high pass filter instead low pass filter.
So cool.
Just compress the lows,if you want.

The high pass filter on a compressor like this just filters the low end from the detector of the compression circuit. You’ll still be compressing the lows AND the highs. I’ve never seen a low pass filter on a compressor before, so I’m not sure where you got that from.

Bah!

I'll believe it once it's been on the market for a year and people I trust say it's good, then hear it myself and agree.

This company has bounced the shiny ball at the kittens and watched them dive for it before.

You are wrong.From the user manual!!!

6. HPF Hz (High-Pass Filter - Hertz)
A high pass filter simply attenuates a selected low frequency (cutoff frequency) and
every frequency below it. All frequencies above the cutoff frequency are passed
through unaffected.
HPF-Hz
30
60
105
125
185
OFF
In this example, 105Hz has been selected as the cutoff frequency.
Therefore, the frequencies which will be attenuated are 105Hz,
and every frequency below 105Hz. All frequencies above 105Hz
will pass through unaffected

I stand corrected, I think. I haven't seen this on any other hw compressor.

I wonder if anyone has a whole studio setup with nothing but Warm gear.

The manual must be incorrect/poorly worded. It should attenuate the sidechain signal (at and below the HPF cutoff) that is going to the VCA's detector so it does not cause the compressor to overreact or pump. If it actually attenuates the frequencies below the cutoff and that shows up on the output in that manner...why do that on a buss compressor?

For example it should be saying something like: 105hz HP attenuates signal strength below 105hz going to the detector for the VCA, therefore the compressor is LESS responsive to frequencies at 105hz and below. That's what should be happening.

I think you were right originally. The wording is a little confusing. Look at all the other SSL style compressors that have a HPF in the sidechain circuit.

Perhaps. I think it’s worded poorly as well. IF it does what is described (however poorly written), then it would be just compressing at the crossover frequency and below.

I think the schematics for this are out in the open. It should be exactly the same as the 4000 G if they followed the schematics. Gyraf Audio even have the schematics available for download if you want to build your own. This more than any other compressor should be trivial to clone. I love SSL stuff but they've been taking the piss on the price of the rack mount G series. $4529 at Sweetwater!! GTFO here man! That's $400 worth of electronics for a design out of the 80s. They've made money with this over the years. I think it's about time they dropped the price a bit.

Here for the gear
 

I was thinking the same thing, it’s crazy I spent the past week researching how to build your own gssl 4000, then warm drops this. Only a couple hundred more and you don’t have to build it and the transformers are exciting. Agree, wet/dry would be a welcome addition. Now I just need to find an la2a diy kit

I can see why this could be confusing, they are describing the fundamentals of a highpass filter.

They are not describing the effect it has on the compressor.

The previous respondent was correct, this highpass filter is used to remove excessive low frequencies from reaching the detector / sidechain signal path. The audio path through the unit does not go through this filter.

Just to be clear, and in the case that this might be a typo, the filter does not affect the signal going to the VCA, it affected the signal going to the sidechain.
Program audio does not pass through this filter.

Why so many guessing?
Just ask Warm audio to be clear, what is correct or wrong.

Warm audio were already quite clear in their description, it's the misinterpretations here that are causing the confusion.

EDIT: The manual has problems. The description of the filter only describes the generic function of a highpass filter.

SO bad.
