WesAudio ngBusComp Analog Bus Compressor with Digital Recall

Stereo/Dual Mono Bus Compressor with Digital Control

Next-gen Bus Compressor with Digital Recall

The WesAudio ngBusComp is a stereo/dual mono bus compressor with full digital control via its advanced companion plug-in that runs on your Mac or Windows computer. WesAudio based the circuitry on a legendary industry-standard bus compressor that has provided the punch and glue for countless hits over the last four decades. Driven by four THAT 2181 VCAs in the signal path (plus one in the sidechain detector), the ngBusComp is a 100% analog device with a massive +24dBu of headroom. Packed with useful features, the WesAudio ngBusComp brings modern innovation to the party with a host of innovative features designed for today’s hybrid studio.


Legendary sound of Stereo Bus compressor has been true companion on countless recordings since 40 years. Often recognized as “mixbus glue”, this particular compression sound have become industry standard. Now, we improve this design creating whole new level of versitality with unbeliveble modern DAW integration –
We present ngBusComp – fully analog, dual mono, stereo, mid-side compressor, with digital recall.



First and most important point – ngBusComp is 100% analog device with +24dBu of headroom.
Regardless its digital control nature, fully analog signal path provides top VCA compression sound.

Four THAT 2181 VCA in signal chain, and one in side chain detector for each channel!

STEREO / DUAL MONO compression!

ngBusComp detectors can be linked and unlinked anytime – what allows us true bus compression behavior, as dual mono compression when needed!

Relative channel linking!

 Channels can be linked/unlinked anytime! It is allowed to have different settings on both channels and still manage those in a relative way!

We can work on Mid-Side mix separately for each channel, but if we would like to change ballance of whole track, it is enough to engage “parameter link” and both channels Make Up gain will be adjusted relatively keeping same amount of volume difference!

MID-SIDE operation mode

ngBusComp supports mid-side opeartion, you can give your side channel

diffferent compression settings then middle channel!


With ngBusComp you can select your output stage to be either

electronically balanced,

or transformer balanced with preceise output PAD!

Drive Carnhill transformers!

In IRON mode it is possible to use Make up gain to drive the transformers, and special output PAD allow to turn signal down!
PAD – passive attenuator managed via relay cascade up to 15dB with 1dB step.


With MIX knob at your disposal, parallel compression has never been simpler to achieve!

With ngBusComp your MIX setting can be automated in your DAW, ever wanted to push your compressor harder in chorus? Nothing simpler! Just record automation using touch sensitive encoder, or draw your automation lines in DAW!

Proprietary THD implementation with very detailed variable control!

 THD stands for “Total harmonic distortion” and it allows to saturate your signal with beautiful analog color. For ngBusComp it can be dialed in very gently or very appearent thanks to variable control with dedicated knob!



ngBusComp Side chain filter functionality allows to modify signal going into the compressor’s detector.

It includes 3 high pass filters at 60,90 and 150 Hz, and 2 tilt filters which are special “curve” designed filters.


ngBusComp provides selectable ratios of 1.5:1 and 2:1 for gentle mixbus processing, 4:1 and 10:1 for large variety of applications, and INF mode – to hit and crash your transients!


External Side chain!

ngBusComp allows to create custom side chain signal to control each channel of compressor!


Even using ngBusComp as pure analog signal processor you can easily switch between three memory settings with a magic of a simple buttons.


USB or Ethernet connectivity!

ngBusComp supports direct USB connection, or you can also managed it in your local network,

just plug in ethernet cable to Your router!

Detailed metering!

Each channel shows detail metering – IN / OUT and Gain reduction!

Of course analog metering is forwared to plug-in instance!



Along with classic analog compressor You receive most demanded feature in audio industry – TOTAL RECALL.

Full plugin control through VST2/VST3/AU/AAX/AAX DSP – makes ngBusComp compatible with most, if not all major DAWs.

Total integration with your beloved DAW will change your workflow forever!


With WesAudio’s ngBusComp you can select your output stage: electronically balanced for a transparent, modern sound; or choose transformer-balanced IRON mode for a beefy, authoritative vintage British console sound. The ngBusComp’s IRON mode uses makeup gain to drive the transformers, and a special output pad (IRON PAD) to attenuate the signal. The IRON PAD is a precise passive attenuator enabled in IRON mode that lets you drive the output transformer to taste for sweet, musical saturation.

Relative channel linking

The Left and Right channels of the ngBusComp can be linked or unlinked at any time. With relative channel linking, you can have different settings on both channels and still manage them in a relative way. You can work on a mid-side mix separately for each channel, but if you want to change the balance of the overall track, simply engage “parameter link” and both channels’ makeup gain will be adjusted relatively, maintaining the same relative volume relationship.

100% analog, full digital control

WesAudio, a company masterminded by Radoslaw Wesolowski and headquartered in Poland, spearheaded an initiative they call “ng,” which stands for next-generation. The company’s first ng products were designed around 500 Series modules with a special connector that mates with receiver connectors in the company’s _TITAN NG500 Recall chassis. On its rear panel, the _TITAN is fitted with a USB jack for connection to your computer, as well as Ethernet for networked setups. All ng500-compatible modules in the rack are able to communicate with your computer via a single data cable.

Now, the ng program has been extended to 19" rack equipment like the ngBusComp. The gear — both 500 Series and rackmount — includes free downloadable software that appears in your DAW session as a standard plug-in and lets you control your analog hardware with software precision. Every setting and automation move is saved along with your DAW session file. How cool is that? Engineers at Sweetwater are deeply into the concept: an elegant marriage of hardware and software, designed for modern hybrid analog/digital workflows.
