ANALOG SOUND, DIGITAL CONTROL

True ANALOG sound with extremely convenient control!

TRUE QUAD VCA THAT 2181

The ngBusComp stands out as a fully analog device, boasting an impressive +24dBu of headroom for superior audio quality. While offering advanced digital control, the compressor maintains an entirely analog signal path, ensuring the renowned VCA compression sound.

Equipped with four THAT 2181 VCAs in the signal path and an additional VCA for each channel’s sidechain detector, this design ensures high-performance and precise compression.

Versatile Stereo/Dual Mono Compression

The detectors can be linked or unlinked at any time, enabling true stereo bus compression or dual mono compression as needed for ultimate flexibility.

Relative Channel Linking

The channels can be linked or unlinked at any time, allowing for independent settings on each channel while still maintaining relative control. When working in Mid-Side mode, each channel can be adjusted individually, but for quick adjustments to the overall balance, engaging the “parameter link” automatically adjusts both channels’ makeup gain while preserving the volume difference.

Flexible Mid-Side Compression Settings

The compressor offers mid-side operation, allowing you to apply different compression settings to the side channel than to the middle channel, providing greater control over the stereo image.

Selectable Output Stages

With the compressor, you have the option to choose between electronically balanced or transformer balanced output stages, with precise control over the output PAD for optimal sound shaping.

 

Carnhill Transformer Drive

In IRON mode, the makeup gain can be used to drive the transformers, while a dedicated output PAD allows you to attenuate the signal. The PAD, a passive attenuator controlled by a relay cascade, offers up to 15dB of attenuation in 1dB steps for precise level management.

MIX Knob: Easy Parallel Compression

With the MIX knob, achieving parallel compression is easier than ever. The ngBusComp allows you to automate the MIX setting directly in your DAW. Want to apply more compression during the chorus? It’s simple — just record automation using the touch-sensitive encoder or draw automation lines within your DAW for complete control.

Enhanced THD Control for Refined Analog Saturation

THD (Total Harmonic Distortion) enables you to saturate your signal with rich analog color. With ngBusComp, you can adjust THD from subtle warmth to prominent saturation using a dedicated knob, allowing for precise control over the distortion effect.

Predefined Sidechain Filters

The sidechain filter functionality allows you to shape the signal before it reaches the compressor’s detector. This includes three high-pass filters at 60, 90, and 150 Hz, along with two specialized tilt filters designed for fine-tuned control.

Five Ratio Settings

The compressor offers selectable ratio settings, including 1.5:1 and 2:1 for smooth mixbus compression, 4:1 and 10:1 for versatile applications, and an INF mode to aggressively clamp down on transients.

External Sidechain

The compressor allows you to create custom sidechain signals, giving you independent control over each channel for more precise compression management.

 

Hardware A/B/C

Even when using the compressor as a pure analog signal processor, you can seamlessly switch between three memory settings with the simplicity of a button press.

USB or Ethernet Connectivity

ngBusComp supports direct USB connection for easy setup, or you can manage it over your local network by simply connecting it to your router via an Ethernet cable.

Detailed Metering

Each channel provides detailed metering for input, output, and gain reduction. Additionally, the analog metering is fully mirrored within the plug-in instance for convenient monitoring.

Analog Automation

We’ve all wanted to adjust device settings based on different song sections, and now it’s possible! Simply draw automation lines in your DAW, and your analog device will follow suit. Plus, you can use the five touch-sensitive encoders to record automation directly into your DAW for seamless control.

Total Recall and Plugin Control

Along with its analog compression, the unit offers TOTAL RECALL, allowing instant recall of all settings for seamless workflow.

Supports VST2, VST3, AU, AAX, and AAX DSP formats, ensuring compatibility with most major DAWs for easy integration.

Full DAW integration and total recall will transform how you work, offering unparalleled control and efficiency.

FAQ

Frequently Asked Questions

Should I uninstall WesAudio application before installing new release?

There is no need to uninstall the WesAudio application before installing a new release. The update process will seamlessly overwrite the existing version.

ng500 Module (e.g. _DIONE) is frozen and doesn’t react to encoder moves – Factory reset is needed

If the module doesn’t react to any changes to the knobs on the front panel, the first necessary step is to rewrite firmware into the flash memory (Factory reset procedure re-writes firmware into internal flash memory – it doesn’t affect anyhow unit configuration). To proceed with factory reset, please follow below steps:

  1. Connect unit either:
    1. Through front panel USB socket,
    2. Or keep the unit in ng500 chassis – _TITAN, but please note that chassis has to be connected to the PC/MAC either via USB or Ethernet cable.
  2. POWER OFF your 500 series chassis.
  3. Depends on the product please press following front panel control:
    1. _MIMAS – RATIO button,
    2. _DIONE – RATIO button,
    3. _RHEA – THD button,
    4. _PROMETHEUS – HIGH CUT encoder (top-right encoder),
    5. _HYPERIONLMF GAIN encoder,
    6. _CALYPSO MENU encoder,
    7. _PANDORA – HIGH SC FILTER (right button).
  4. While keeping this control (button/encoder) pressed, POWER ON your 500 series chassis.
  5. LEDs should present a strange pattern.
  6. Now open GConManager:
    1. WIN: C:/Program Files (x86)/WesAudio/GConManager.exe
    2. MAC: /Applications/WesAudio/GConManager.app
    3. Or click on the WesAudio “Tray” icon, and select “Open GConManager”
  7. Go to _UPGRADE application.
  8. Hit start!

    2. MAC: /Applications/WesAudio/GConManager.app
    3. Or click on the WesAudio “Tray” icon, and select “Open GConManager”
  7. Go to _UPGRADE application.
  8. Hit start!
Unit passes signal only when bypassed

This is a very common issue and in most cases the root cause lies in the connection of the unit and audio interface. If that happens it should be checked if audio interface input isn’t connected to the chassis input and if audio interface output isn’t connected to chassis output. As this initially would seem to be entirely wrong and shouldn’t work at all, as all our units implement “True Bypass” via relays, the unit will pass a signal when the bypass is engaged. The reason for that is that the relay is in fact hard wiring input to the output, and thus the unit will pass the signal, as it doesn’t go through any active circuit of the unit.

Plug-in doesn’t connect to hardware when a plug-in instance is created

This is actually how it is supposed to work, so after the plug-in instance is created, please use a small triangle button which usually is on the bottom side of the plug-in and select proper HW ID from the drop down menu. If the drop down menu doesn’t list any hardware units, please check Your connectivity and other possible root causes in this FAQ.

Unit can’t connect to a plug-in

This is a wide topic, and there may be at least several root causes, but there are few things that should be checked. However, the first and most important thing is to double check that GConManager doesn’t list this device in the _CONFIG app. If this is the case, it means that WesAudio unit can’t connect on the OS level, and some of the below steps may help:

  1. First of all double check if module connection is properly executed, this procedure is described here.
  2. USB specification indicates that USB 2.0 works up to 5 meters. This is however not entirely true, as it strongly depends on the peripherals that unit is connected to. Even if our modules are USB 2.0 compatible, your USB port could support USB 3.0 – USB is a backward compatible protocol, so it may be that USB 3.0 cable length limit should be considered which is 2 meters. We would recommend having a USB cable up to 2 meters to remove those limitations from the equation.
  3. USB HUB is very common root cause to those problems, if module can’t connect via HUB – just for the sake of the test, it is mandatory to connect unit directly to PC/MAC to verify if the problem isn’t caused by it.
  4. Please note any system warnings attached to “WesAudio Tray Icon”.
Unit disconnects by itself

As USB controllers have limited capacity it could be a reason for random unit disconnection. Usually, it happens when a lot of USB devices are plugged into the PC/MAC. The usual behavior would be that the unit works normally, and after reboot it doesn’t, but it strongly depends on the OS implementation so exact reaction could be a little bit different. If this is suspected, just for the test, it would be good to disconnect most of the devices from the USB ports, reboot PC/MAC and double check the connectivity from stability point of view. If it leads to the conclusion that this is the root cause of the problem, we would recommend using a decent USB hub, and ideally a TB/USB dock station which tends to offload a lot of responsibilities from our PC/MAC.

Unit can’t connect anymore

If the unit was working fine, and suddenly it couldn’t connect (it is not visible in the GConManager _CONFIG app) that could lead to the conclusion that some devices were added to our USB line, and we could have problems with the USB controller inside PC/MAC. In that case please check the description in the above “Unit disconnects by itself”.
