Independent shopping perspective
The Korena take
Four channels of 350W at 4 ohms make the Connect 354 a focused choice for installed systems that need independent amplifier channels in a compact rack space. Built-in Wi-Fi, Ethernet, cloud control, and external I/O support remote operation and health monitoring once it is on a network. Its 32-bit, 96kHz DSP provides per-channel EQ, crossover, and delay tools, while the routable input matrix lets you direct sources where they are needed.
Strong match
Who this is for
- Managing multiple speaker zones from a networked control position in a fixed installation.
- Tuning four amplifier channels with per-channel EQ, crossover filters, and output delay.
Consider the trade-offs
When to look elsewhere
- Systems requiring more than four independently amplified channels from one unit.
