Frequently asked questions
What is the key difference in processing capabilities between these two units?
The 640m provides basic transparent zone processing and control, while the 640 includes extensive DSP tools like gating, de-essing, compression, feedback suppression, AutoWarmth, EQ, crossover filters, and delay on outputs. The 640 is designed for complex commercial audio applications requiring sophisticated signal shaping.
Which unit is better for tight installation spaces?
The 640m is specifically engineered for retrofit applications with a shallow 1.75-inch depth, making it ideal for space-constrained AV systems. The 640 is a standard-depth commercial processor without the same compact design emphasis.
Are these units suitable for paging and commercial audio systems?
The 640 is purpose-built for commercial audio including paging systems, with dedicated microphone processing, priority override, and source ducking features. The 640m is better suited for simpler zone distribution and installation audio control rather than complex paging applications.
What control and integration options do each offer?
Both units feature Ethernet and RS-232 ports for remote operation and third-party control integration. The 640m emphasizes on-unit hardware control with LCD feedback, while the 640 provides comprehensive routing and DSP control designed for commercial system integration.
