The large PPM is approximately life size. As this is may be a bit large here is a smaller version. Click the push button to switch to M/S mode. There is no 20db boost button. If you don't want to switch to mono/stereo mode the window can be closed down to obscure the switch. As usual, right click to access the options. When the switch is obscured you can still change modes by double-clicking on the window.
