Product Information

The AXB-VOL3 Three-Channel Volume Control provides three audio volume control channels. Each line-level channel, opto-isolated from system ground, can be configured for balanced or unbalanced line operation. The AXB-VOL3 is programmable for 128 steps of audio level, audio mute, variable ramp speed and level presets. The AXB-VOL3 connects to Axcess control systems using the 4-wire AXlink data/power bus; it can be used for remote or rack mount applications.
