The Cobalt® ROYAL 9243 Analog Audio Distribution Amplifier with Remote Gain Control is a broadcast-quality balanced analog audio DA with stereo 2×4, mono 1×8, and stereo sum L+R x 8 selectable output modes.
Unlike most analog audio DAs, the 9243 electronic attenuators allow overall gain (stereo ganged) and per-channel trim (offset) via DashBoard™ remote control.
The space-saving design and very low power consumption of the 9243 provides for high density, allowing two cards to be collocated in adjacent slots and served by a single, standard – width “split” rear module.
