Item was quoted wrong for an install and was never used.  Brand new, just no box.  Very minor adhesive residue on the front from a label that was taken off. IEC power cable is included. 

4 Channel x 30W @ 4/8 Ohms, 70/100V Smart Amplifier w/ Dante, DSP, Wi-Fi or FAST Ethernet Connectivity

The CS34D is a 4-channel amplifier with 30 watts per channel, designed in a compact ½ rack space form factor. It is a part of the Dante CONNECTSERIES, the first IoT-enabled professional-grade amplifiers globally. Ideal for small to medium-scale installations, it features direct HiZ (70V or 100V) or LoZ selectable by channel. The amplifier offers three connection options: built-in Wi-Fi access point, venue's Wi-Fi, or FAST Ethernet for local area network connectivity via Cat5 or Cat6 cable.

Additionally, as part of the Network CONNECTSERIES, it is the first professional amplifier family with Cloud connectivity. This allows users to remotely control, monitor, receive notifications, and more from personal devices. Simply connect the amplifier to a network and take command of your systems.
