Controlling Preamp Gain
The Preamp section is used to adjust the analog (hardware) gain and the digitally adjusted output level of the I/O
device’s preamp. There are two modes for controlling preamp gain: Preamp and Local. Select a mode with the
button above the preamp control knob.
Preamp mode (left) adjusts the preamp’s analog gain, just like the preamp gain control in the device’s control
panel. Preamp analog gain value is displayed above the knob.
.
In Local mode (right), the Gain knob becomes the V-Gain knob (Virtual Gain). V-
Gain is a digital gain stage that always delivers the user’s requested input gain,
regardless of the preamp’s analog gain setting. Using V-Gain, you can adjust
channel input without affecting the preamp’s analog gain structure. Your input
level will not change, even if you adjust the hardware gain. See the next page for
details. Preamp and Local modes share the scale of the current preamp gain. The
offset between preamp analog Gain and V-Gain is shown by a green ring around
the V- Gain knob.
Preamp state (Preamp or Local) and Gain values are saved with a session and are recalled
when the session is loaded. The Gain and V-Gain values can also be stored with scenes. When
recalled, the value will be applied to Gain or V-Gain, depending on which mode is active. When
moving from Local to Preamp mode, the V-Gain value is sent to the Preamp control, and the
preamp takes on the V-Gain value.
Save a session in Local mode and you can later open it with the same gain, regardless of the current preamp analog value (e.g.,
someone changed the analog gain settings since the last time you used the system).
I/O Sharing
Several eMotion LV1 systems can be connected via an Ethernet switch to create a networked
“super system.” Users throughout this super system can assign any available I/O device to
their eMotion LV1 system. Once a device is assigned, it is no longer available to other users,
unless the device is shared. I/O sharing allows several mixer systems to share the same I/Os. To
enable I/O sharing of an assigned device, go to the device’s menu and select “Share,” or click
the network symbol on the device icon.
All users will see the preamp gain value but will not be able to change it. To allow users on a
super system to control preamp gain on shared devices, the manager of the device (the
person who initially assigned the device), must select “Share Preamp Control.” Refer to
Chapter 1 > Setup Window > I/O Sharing to learn about I/O sharing.
