Anyway, the strong point of Revolution 7.1 is music and DVD playback rather than game sound. The next menu item, No Surround Processing, turns off virtual sound processing. It is recommended for use in case the audio content is already in a multi-channel format and doesn’t require any sound sources virtualization.
The last menu item enables surround sound technologies from SRS Labs. If a multi-channel speaker system is selected in the Speaker Setup tab, the SRS Circle Surround II option appears. If headphones or a stereo-system is selected, you will see the SRS TruSurround XT option.
SRS Circle Surround II technology serves to reproduce stereophonic content (Audio-CD, MP3 and so on) on a multi-channel speaker system. There are three algorithms for distributing stereo/mono signal to six or more speakers.
SRS TruSurround XT technology creates a virtual multi-channel environment through a pair of speakers. This option appears in the control panel, when the user selects a stereo-system (Stereo), Stereo with Subwoofer, or Headphones.
When SRS technologies are activated, you gain access to two functions – SRS Dialog Clarity and SRS TruBass. The former is for making the sound more distinct and clear to the ear (drag the Dialog Enhancement Level slider). The latter takes out bass from the reproduced audio-track and directs it to the satellites. This function must be intended for games for you to enjoy the roar of rocket engines or the sound of the boarding peeling off the submarine at an abyssal depth. The level of the reproduced bass is controlled by the TruBass Level slider.
This section of the control panel allows you to adjust the level of the incoming signal. Note that the line-in level adjustment is here combined with the microphone level adjustment. Clipping indicators are located next to the channels sliders. In the right part of this tab you set the sample rate (in most cases it is set automatically, according to the application request) and the size of the ASIO buffer.
As any other Envy24-based sound card (the new version of the controller, as well as the older ICE1712), Revolution 7.1 can work with Cubase. In this section of the control panel you choose the size of the buffer that is responsible for changing the delay in the working track.
This window shows the version of the installed drivers. During the tests I used a control panel of version 220.127.116.11 with a driver version 5.10.00.0036.
