Setting Up System - Redx Sapphire III Owner's Manual

Setting Up System

This chapter is about the configuration of a set of power amplifiers using the Dante™ network. Not only independent
connections can be set up, but also multiple power amplifiers can be connected as "Daisy Chain". Sapphire III (Base)
connects to the network hardware devices using Cat-5 cable. Sapphire III (Base) implements 4-in, 4-out audio signals,
Digital Signal Processing and other configuration.
Audio signal inputs
Audio signals can be input from Dante™ audio input or analog audio input:
• If "Dante™ Audio" is chosen, PC/Network switch is used to input audio signals and control the amplifier remotely.
Ethernet ports ETH1/ETH2 can input/output signals simultaneously, as Dante™ is bidirectional.
• If "Analog Audio" is chosen, XLR is used as the input source. A PC can only control the internal functions via the UI.
As the images show below, a single power amplifier is used as an example:
• If "Dante™ Audio" is chosen, PC/Network switch is used to input audio signals and control the internal functions.
There is signal from the analog input.
• If "Analog Audio" is chosen, XLR is used to input audio signals. PC can control internal functions via the UI.
Single power amplifier system (STEREO mode):
Ethernet Data Stream (Bidirectional)
Audio Data Stream (Monodirectional)
Analog Audio output

Single power amplifier system (BRIDGE mode):
Ethernet Data Stream (Bidirectional)
Audio Data Stream (Monodirectional)
STEREO/BRIDGE mode
STEREO/BRIDGE mode can be selected through the switch on the rear panel or through the UI.
For Stereo mode connection (figure 1):
• Signal input from CH A, CH B, CH C, CH D and output from corresponding channel A, B, C, D.
For Bridge mode connection (figure 2):
• "Bridge A B": Signal is sourced from CH A and output from channel A with doubled power,
channel B is disconnected.
• "Bridge C D": Signal is sourced from CH C and output from channel C with doubled power,
channel D is disconnected.
