These power amps were pulled from a working environment. All power amps had their firmware updated to V3.0.2.15 and include only those accessories shown in the pictures.
Pictures are only of one of the units available so the unit you receive may not have the same exact blemishes. They are all in excellent condition with some scratches and scuffs (like the one pictured), but nothing major.
The power amps have clocked in at most 247 days of being in operation/use.
If you have any questions, please reach out to us. Additional information about the units can be found below.
System installers in search of a professional audio amplifier with Dante and wireless networking capabilities will be thrilled with the LEA Professional 704D Connect Series, a 700W 4-channel audio amplifier equipped with a web browser-based user interface that works on any device with no software to download.
The amplifier is well suited for small- to medium-scale installations and features direct Hi-Z (70 or 100V) or Lo-Z selectable by channel. Connect via the built-in wireless access point or via venue’s Wi-Fi or use the FAST Ethernet to connect to any local area network (LAN) with a standard Cat 5/6 cable. The Dante Connect Series is the first professional amplifier family to feature Cloud connectivity, which allows you to remote control, monitor, get notifications, and more from any personal device. Connect the 704D to a network and start commanding your system from anywhere.
