Beta76 FET compressor/limiter

The introduction of several significant structural  improvements against the original version.
One of the most important changes is two mode switch – Modern / Vintage –  deciding  on the circuit of the desymmetrization of the input signal.
Modern Mode – is an  electronic circuit, exactly the same as the previous version of the compressor and the Vintage mode – it’s a Carnhill input transformer. The result is a universal device with two different sound possibilities.

A True Bypass switch was introduced,  as well as  a high-pass filter in the Compressor’s  Side Chain  path.There are three cutoff frequencies – 60, 90, 150 Hz – thanks to which Beta76 is less sensitive to low frequencies. The filter is particularly beneficial to the operation of two compressors in a stereo pair, which are easily connected with a  prepared Jack-Jack cable.

The entire system operates in class A. The element responsible for the gain reduction is a  FET transistor,  giving the effect of rapid and pure compression. There is a  high quality Carnhill audio transformer  on the output favourably affecting the final sound of the compressor.
The housing is made from high quality brushed stainless steel, whereas  the panel  is 4mm brushed aluminium.

FAQ

Frequently Asked Questions

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.
  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. 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”.
