Independent shopping perspective
The Korena take
Connect 704 is a four-channel installation amplifier rated at 700W per channel for 4Ω, 8Ω, 70V, and 100V applications. Its internal DSP and crossover processing keep channel setup within the amplifier, while a built-in Wi-Fi hotspot, venue Wi-Fi, or Fast Ethernet connection opens access to cloud control, monitoring, and notifications. Analog inputs, remote on/off control, and fault monitoring support a system designed to be managed from beyond the equipment rack.
Strong match
Who this is for
- Four-channel fixed installations that need 700W per channel at the listed load options.
- Systems where remote monitoring, switching, and cloud control are part of the installation workflow.
Consider the trade-offs
When to look elsewhere
- Installations needing more than four powered channels from one amplifier.
