functionality includes the ability to configure parameters specific to a processors,

preset selection, detailed parameter tuning, custom processing profile creation, and

much more. Monitoring capability include global view of the processor health and

VU meters tied to the Input/Output of each processor.

Installing Perceptual Soundmax Manager

•

Minimum system requirements

Operating System:

SoundMax Manager

is currently available for Windows

XP, Windows Vista and Windows 7 (32-bit) operating systems.

LAN Connection:

The Manager communicates with the Station through a

network connection.

Hardware:

The SoundMax Manager

can run on any light weight PC. We

recommend at least a single core Pentium with a clock speed of 2.2

GHz (or above).

•

Instruction for installation

Setting up the MANAGER

Run the SoundMax Manager setup on a PC and follow the

instructions

After the installation SoundMax Manager user interface screen (UI)

will come as shown below:
