A2005/A2007 System Control Protocol
Introduction
The A2005/A2007 Audio amplifier contains four different control systems that can be used for basic control,
custom installations, end user or installer diagnostics, and IP based control systems. The amplifier contains a
+12V trigger Input, RS-232 control port, an Ethernet control port, and a built in web server. These four control
systems are outlined in detail in this document. The illustration below has been provided to identify each
connection on the back of the amplifier.

1 - External 12V Trigger Input
Within the network module section, a 3.5mm jack allows for connection to a typical 5-24V trigger output from an
external pre-amp or pre-amp/processor via a stereo 3.5mm cable.
2 – RS-232 Serial Control Port (DB-9)
The network module section contains an RS-232 DB-9 connector for interface to an external system controller.
Contact Indy Audio Labs for a list of verified control system manufacturers.
3 - Ethernet Network Active LED
The Ethernet Network Active LED illuminates green with an active network connection between the Acurus
amplifier and a network switch or router.
4 – Ethernet Jack Connection (Web Control or UDP Control)
The Ethernet jack enables connection to either an external system controller or to a standard home Ethernet
10/100 network switch or router port. Control and status monitoring of the amplifier using any device with a web
browser is supported via the web server embedded in the Acurus amplifier.
This document is designed to be used in conjunction with the A2000 Series Product User Manual and will be
referenced multiple times throughout this document. The manual can be downloaded at the Acurus website,
