2. I/O Level Information
Both the R1 and the Red range device under control are able to adjust the volume of the loudspeakers
connected to the Red device’s analogue outputs.
Having two control locations on the monitor system could result in there being either insufficient
range or high sensitivity of the R1’s Output Level encoder. To avoid either possibility, we would advise
using the following loudspeaker setup procedure:
Setting the Maximum Volume Level
1 Set all the analogue outputs on the Red range unit to a low level (but not muted), using either
the front panel controls or via RedNet Control
2 Turn the volume control on the R1 to maximum
3 Play a test signal/passage through the system
4 Slowly increase the channel volumes on the Red unit until you reach the highest loudness
level that you would prefer coming from your speakers/headphones
5 Use the volume and/or Dim control on the R1 to reduce from this level. Now continue to use
the R1 as the monitor system volume controller.
The procedure is only necessary for the analogue outputs (digital outputs are affected only by the R1’s level control).

Level Summing
When Summing behaviour is enabled in the Tools menu, it automatically adjusts the output level to
maintain a constant output when sources are added or removed.
The level of adjustment is: 20 log(1/n), ie., approximately 6dB, for every source summed.
