About this User Guide This user guide applies to the RedNet AM2 Dante headphone and line output interface. It provides information about installing and using the unit, and how it can be connected into your system. A RedNet System User Guide is also available from the RedNet product pages of the Focusrite website. The guide provides a detailed explanation of the RedNet system concept, that will help you achieve a thorough understanding of its capabilities.
INTRODUCTION Thank you for purchasing the Focusrite RedNet AM2. RedNet AM2 provides two channels of premium D-A conversion in the form of a stereo monitoring unit, combining headphone and line outputs for monitoring of signals from the Dante Audio-over-IP network. RedNet AM2 includes two line-output XLRs plus a stereo TRS 1/4” jack socket.

Use standard Cat 5e or Cat 6 network cables to connect RedNet AM2 to an Ethernet network switch. Power over Ethernet (PoE) can be used to power the RedNet AM2. Connect an appropriately powered Ethernet cable to network port 1. 2.
Physical Characteristics 140mm / 5.5” 47.5mm / 1.9” 104mm / 4.1” RedNet AM2 dimensions are illustrated in the diagram above. RedNet AM2 weighs 0.81 kg and is equipped with rubber feet for desktop mounting. The baseplate includes a female 3/8” BSW thread so the unit can be mounted on a microphone stand. RedNet AM2 generates little significant heat and is cooled by natural convection. The ambient operating temperature of the device is 50 degrees Celcius.
REDNET AM2 OPERATION First Use and Firmware Updates Your RedNet AM2 may require a firmware update* when it is first installed and switched on. Firmware updates are initiated and handled automatically by the RedNet Control application. *It is important that the firmware update procedure is not interrupted – either by switching off power to the RedNet AM2 or the computer on which RedNet Control is running, or by disconnecting either from the network.
OTHER REDNET SYSTEM COMPONENTS The RedNet hardware range includes various types of I/O interface and PCIe/ PCIeR digital audio interface cards which are installed in the system’s host computer or in a chassis. All the I/O units can be considered as “Break-Out” (and/or “Break-In”) boxes to/from the network, and all are built in mains-powered, 19” rackmount housings, unless otherwise stated. There are also three software items, RedNet Control (see below), Dante Controller and Dante Virtual Soundcard.
ID (Identification) Clicking on the ID icon will identify the physical device being controlled by cycling its front panel “Network” and “Signal” LEDs through green–orange–red states for 10 seconds. Tools Menu Clicking on the Tools icon will gain access to the following system settings: Line Level Setup – Sets the analogue line output level at 0 dBFS: • +18 dBu • +24 dBu (factory default setting) Mute (Line Out) – On/Off state. Mute on Power-up – On/Off state (factory default is On).
