BRAX nOX4 DSP Bedienungsanleitung Seite 26

Connecting a computer and installing the software
To configure the signal processor manually the NOX4 DSP must be connected to the computer by using the
supplied USB cable. The current PC Tool version is always on our homepage www.audiotec-fischer.
com. The latest version of the application is always available for download. It's under "Downloads" in the "PC
Tool" section of the top menu. We recommend regularly checking before each use of the software for versi-
on updates. Note that PC-Tool version updates mean that the DSP operating software must also be updated.
Important: Make sure the NOX4 DSP is not connected to your PC prior to software installation. Connect and use it only
after the software has been completely installed on your computer. To ensure fault-free operation, always use the latest
PC Tool version available.
Software installation:
1. Download the software from the homepage previously mentioned from the „PC-Tool" section to your computers hard drive.
2. Unzip the file on your hard drive. Important: This folder must not be on a portable storage device such as a USB
thumb drive - it must be saved on the hard drive.
3. Double click the USB driver.exe file to start it and install the USB interface driver. This MUST be done before the „PC-Tool
Rev X-xx.exe" program is started. Note: The installation may last up to one minute.
The software is ready for use once the driver installation is completed. The NOX4 DSP can now be connected to the computer
and the DSP can be freely configured via the PC-Tool software.
Note: We recommend reducing radio volume to the minimum before first use or not connecting any amplifier to
the pre-amplifier NOX4 DSP output/s until the basic setting (especially high- and lowpass filter) have been adju-
sted in the processor. Not doing so may damage any connected loudspeaker/s. Fully active systems in particular
have an inherent risk of damage even at low volume.
