NXC-VOL4 Volume Control Card
The NXC-VOL4 Volume Control Card (
FG2024
) provides four discrete volume control channels with LED
feedback.
The volume control channels can be programmed for mono or stereo operation, and balanced or unbalanced
audio connections. It supports programmable audio levels, audio mute, variable ramp speeds and preset levels.
Use the on-board jumpers to set the gain/attenuation (Unity, Pro level (+4dBu) to Consumer level (-10dBu)
conversion, or Consumer level to Pro level on each channel). FIG. 8 shows the VOL4 card.
