Key Features
Flexible Multi-Channel Power: Delivers 700W x 4 into 4 $\Omega$, 8 $\Omega$, 70V, or 100V loads, as well as 350W x 4 into 2 $\Omega$
Dante & AES67 Networking: Primary and secondary Ethernet ports support up to 8x8 Dante audio channels at 96kHz or 48kHz resolution with AES67 compatibility
Proprietary Smart Power Bridge Technology: Allows you to double the output power on a selected channel (up to 1,400W) without sacrificing or disabling adjacent channels
Onboard 96kHz Analog Devices DSP: Integrated 32-bit/96kHz DSP features routable input matrixing, up to 48dB/octave crossovers, 8-band parametric EQ per channel, 100ms delay, and peak/RMS limiting
Browser-Based Web UI & Cloud IoT: Built-in Wi-Fi access point, Ethernet network port, and browser UI enable local device setup and cloud monitoring via AWS IoT Core or LEA's SharkWare software
Real-Time Load Monitoring: Continuous impedance testing and pilot tone detection ensure early fault warnings and system health verification
Channels: 4 Output Channels
Power Output (per channel): 700W @ 4 $\Omega$ / 8 $\Omega$ / 70V / 100V; 350W @ 2 $\Omega$
Engineered for modern commercial installations, the LEA Professional Connect 704D combines high-density Class-D amplification with advanced IoT capabilities and Dante digital audio networking. Delivering 700 watts per channel in a compact 1U rack-mountable chassis, the 704D is built to power medium-to-large venues including auditoriums, corporate facilities, hospitality venues, and houses of worship. Leveraging cloud connectivity powered by Amazon Web Services (AWS) IoT Core, system integrators can monitor and control installations remotely from anywhere in the world without requiring a dedicated VPN.
