The D SERIES-NVC2 is a rotary control that provides volume control and muting on one or two Dante/AES67 network audio channels. One or two mono audio sources or one stereo audio source may be routed to the -NVC2, then from the -NVC2 to a network destination, typically a power amplifier. Audio level adjustment is performed digitally in the -NVC2. The installer has the option of setting the unit to sum the left and right channels of a stereo source with the mono sum feeding both outputs. The level of each output channel may be adjusted separately or together. If two or more user adjustment controls are desired in the same zone, an RDL D-NMC1R may be used to remote control the -NVC2, allowing adjustment by either unit. Network bandwidth typically supports up to 4 remote controls per zone.

Opening the installer-enabled MENU provides for selecting which output channel to adjust or to select simultaneous adjustment of both
outputs. The -NVC2 connects to a local network that may include compatible RDL audio and control modules as well as Dante devices from RDL and other manufacturers. The unit is menu-driven using a full-color LCD display.

The VOLUME display shows the relative level using segments in a circular pattern. The level is adjusted by the user using the rotary encoder knob with mechanical detents. The knob rotation includes pre-programmed acceleration when the knob is turned quickly, such as to reduce an unexpectedly high level or feedback. The installer can refine the acceleration during the unit setup in CONSOLE. A user can mute the audio by momentarily pushing the knob. The muted condition is shown on the display, as well as on the display of other RDL remote controls that are set to control the volume of the -NVC2. While muted, the next momentary knob push will unmute the audio at its prior volume setting. If, instead, the user rotates the knob clockwise, the volume will ramp up, from fully “off”, according to the rotation of the knob.

Each function may be configured to automatically lock after 30 seconds of inactivity. Inactivity timeout is programmable by the installer. When a function is locked, a passcode is required to unlock that function. The passcode is programmable by the installer and may be reprogrammed if required. After 30 seconds of adjustment inactivity, the -NVC2 display is dimmed. It returns to normal intensity upon any knob activity.

The field-upgradable -NVC2 provides stereo to mono summing and independent or single output volume control of network audio in an
intuitive and attractive interface that is flexible and powerful, yet simple to operate.

*Note: Network audio flows pass through and are directly adjusted by the D-NVC2. The D-NVC2 may also be remotely controlled by compatible remote controls such as the RDL D-NMC1R or D-NLC1R.
