Driver Configuration

Properties

Driver Status

• Driver Version - Reports the current version of the driver.
• Operational Mode - Reports the status of the driver, including information on any faults.

Configuration

• Device IP - Enter the IP address of your K-Array device to establish communication between the driver and the amplifier.
• Polling Interval - Choose the time frame for collecting state info from the device (in seconds).
• Volume Group X - You can group the output channels to assure the variation in the volume of a single channel in the group is propagated to all other channels. Write the channel number separated by a Colon (e.g. 1:2:6:8 create a group containing channels 1,2,6 and 8). This also affects mute functionality when any member of a group is muted all members of a group will be muted.
• Volume Group X Offset (dB) -For some systems, you may need to maintain a volume difference between members of the volume group. The offset is per channel however the first channel in the group must always have an offset of 0 and then offset all other channels from the first channel in a group. example 0:10:10:5 will would set channel 2 by +10 and channel 8 by +5 based on a Group 1:2:6:8 all channels are offset from channel 1 in this example
• Media Player Input - Enter the input used for Media via the INPATCH routing. This input will be switched when the USB source is selected.
