This massive analog unit has every mix buss feature known to man, and is controlled via your DAW!

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

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
