Independent shopping perspective
The Korena take
Connect 354D pairs four 350-watt, 4-ohm channels with Dante networking and built-in Wi-Fi and Ethernet for installed audio systems. Its analog and Dante inputs accommodate both connection types, while cloud access supports remote power control, performance monitoring, and notifications once the amplifier is on a network. The 32-bit, 96 kHz DSP provides configurable crossovers, parametric EQ, and output delay on every channel, backed by load monitoring, remote I/O, and a routable input matrix. It occupies 1U and uses front-to-rear variable-speed fan cooling.
Strong match
Who this is for
- Fixed installations needing four 350-watt channels at 4 ohms with Dante and analog input options.
- Dante-equipped systems that need remote amplifier control, monitoring, fault indication, and per-channel DSP.
Consider the trade-offs
When to look elsewhere
- Systems requiring more than four amplifier channels.
