Page 8: Panel Description
PANEL DESCRIPTION RJ-45 Ethernet connectors for optional Dante digital audio network card with two network ports; a primary and a secondary. When the device is connected to an active network, the yellow LINK LED illuminates above the connector in use. Data activity on the network is indicated by illumination of the green ACT LED.
Page 9: Signal Flow
SIGNAL FLOW The figure below depicts the audio signal flow for a A4M SCiO series device. The signal flow can be divided in three main blocks, each with its own functionality and processing. These blocks are : input source, group and speaker blocks.
Page 10: Group
GROUP Groups provide powerful control over all channels in a system. Amplifiers can be assigned to up to 6 different Groups. Adjusting group parameters will affect all amplifier channels across the network assigned to that group. Multiple Groups can be used to logically partition a large-scale system. For instance, an amplifier can be assigned to the “frontfill group”...
