1176-style analog compressor with digital recall

Since 1968, FET-style compression has been a dominant force in countless recordings, remaining one of the most popular processing techniques to this day. Known for its lightning-fast attack and release times, it has become an essential tool for audio engineers. Wes Audio proudly introduces _MIMAS — an ng500 series processor that incorporates the legendary FET design, now enhanced with the highly sought-after feature of digital recall.

Main Features

_MIMAS: A Modern Take on a Legendary Compressor.

ANALOG SOUND, DIGITAL CONTROL

Same legendary fet compression

_MIMAS – Powered by Carnhill Transformers at the Core of Its Sound.

The most important feature of _MIMAS is its fully balanced analog design (IN/OUT) with +24dBu of headroom. Despite offering digital control, the signal path remains entirely analog, delivering the authentic FET compression sound that professionals expect.

Four Ratio Settings and Legendary “All Buttons In”.

_MIMAS offers selectable classic ratios of 4:1 and 8:1 for compression, and 12:1 and 20:1 for limiting.

For those needing a more aggressive compression style, the “All Buttons In” mode is ready to use. And just to be clear—it’s an analog compressor, so the “All Buttons In” mode is fully analog too!

Saturation Mode: One Knob to Add Color and Character Without Compression

Classic 1176 compressors allow users to disable compression while still adding warmth and character to the signal. _MIMAS follows this tradition but takes it a step further by using a single knob to control the amount of saturation applied to the signal, making it easier to achieve the desired effect without needing to adjust both the input and output knobs.

500 Series and ng500 Series Compatible

Regardless of its additional features, _MIMAS remains fully compatible with the 500 series standard(*). Digital functionality can be activated via the front panel mini USB socket.

The ng500 — Next Generation 500 series – is a physical extension of the standard 500 series, making _MIMAS fully compatible with the _TITAN frame, allowing control of all devices in the chassis through a single USB or Ethernet cable.

(*)Important note about 500 series extension: See note

Hardware A/B

Even when using _MIMAS as a purely analog signal processor, you can effortlessly switch between two parallel settings with the simple press of a button, offering quick and seamless control.

Total Recall and Plugin Control

Along with its classic analog compressor, _MIMAS brings one of the most highly demanded features in the audio industry — TOTAL RECALL.

Full plugin control via VST2, VST3, AU, AAX, and AAX DSP makes _MIMAS compatible with most, if not all, major DAWs.

Total integration with your DAW of choice will transform your workflow forever!

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!
The NGRack unit (e.g. ngBusComp) 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 the unit to either USB or Ethernet.
  2. POWER OFF your unit.
  3. Depends on the product please press following front panel control:
    1. ngBusComp – far left Ratio on Channel 1 (Ratio “-”),
    2. ngTubeEQ – THD encoder on Channel 1,
    3. ng76 – “IN MODE” button,
    4. ngLEVELER – use a small screwdriver and press button available on the rear panel via a small hole in the chassis.
  4. While keeping this control (button/encoder) pressed, POWER ON your unit.
  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!
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”.
