RME AVB Tool User’s Guide It is possible to adjust the gain of individual channels even when they are part of a gain group. 9.1.8. Creation and Use of a Gain Group To create a group that controls the gain of two or more channels at once, proceed with the following steps: the group can include TRS inputs that have a different gain range.
9.1.10. Monitor Analog Inputs at Phones Output The phones output at the front of the AVB Tool can receive any input signal. Permanent routings are configured in the Phones Output settings (see Routing Signals to the Outputs and Phones Output).
• by opening the phones output and deactivating the mode there. If there was a previous routing, it will be re-established immediately. 9.2. MADI Input The AVB Tool accepts up to two MADI signals, one electrical (BNC input) and one optical via SFP option (LC input). To connect a MADI signal: 1.
For a seamless failover, the two MADI signals must be identical. However, only the SYNC and LOCK states are evaluated to confirm the current input state. It is therefore possible to send two different signals to the AVB Tool as long as they are in sync. 9.2. MADI Input | 52...
4. Connect both MADI signals with identical audio. 9.3. AVB Input Streams The AVB streams received by the AVB Tool are referred to as "input streams". For these streams, the device acts as an AVB Listener. To establish a connection between a talker and a listener, an AVDECC Controller is required. The AVB Tool does not include an AVDECC Controller.
Page 59
RME AVB Tool User’s Guide To change the amount of channels and format of incoming AVB streams: 1. Open the AVB tab in the INPUT section. 2. Use the first button and encoder to select an incoming stream. 3. Use the second button and encoder to change the stream size and format.
Example: In the OUTPUT section, MADI Optical 1-12 is chosen as source for AVB Stream 2. The AVB Tool is clock master, but the incoming MADI signal is not correctly synchronized. This causes a warning in the INPUT section.
RME AVB Tool User’s Guide To create a routing to a MADI Coaxial output: 1. Open the routing tab of the MADI Coaxial output in the OUTPUT section (see Use of the Display and Encoder). 2. Activate the routing destination and choose an output channel with the encoder (steps 1 and 2).
RME AVB Tool User’s Guide To adjust the headphone volume on the device: 1. While on the main screen, rotate the encoder. The current volume will be shown below the encoder on the screen. To separate the left and right headphone channels: 1.
RME AVB Tool User’s Guide 10.2.4. Using Phones Out as a Balanced Line Output The headphone output can operate as a mono balanced line level output. This may for example be useful when an active talkback speaker with symmetrical input is connected to the 12Mic.
10.3. MADI Outputs The MADI outputs of the AVB Tool are always active. If no routing is configured, an empty stream is sent that can be used for clocking. The state without routing is represented with a light-green Status Indicator.
10.4. AVB Output Streams The AVB streams leaving the AVB Tool are described as "output streams". In this case, the device acts as a talker. The talker defines the presentation time and therefore the latency across the network. This is set per default to 2 ms.
