Frequently asked questions
Which amp suits constant-voltage (70V/100V) speaker systems?
Only the CDi2x300BL offers built-in 70V and 100V direct-drive modes, making it the only choice for architectural or large commercial installations using constant-voltage speakers. The CTD-4125-US is designed for low-impedance speaker systems and networked environments.
Can both amps work in networked audio systems?
Yes, but differently. The CTD-4125-US uses Dante as its sole input method and is designed for Dante-native systems. The CDi2x300BL accepts analog inputs plus BLU link digital networking, offering more connectivity flexibility for hybrid setups.
Which is better for a single high-power output zone?
The CDi2x300BL delivers 300W per channel, ideal for powering a large speaker system or venue zone. The CTD-4125-US splits 500W across four channels (125W each), better suited to multiple zones than single high-power applications.
What skill level do these require?
The CDi2x300BL is accessible to intermediate users due to straightforward analog connectivity and front-panel controls. The CTD-4125-US assumes professional familiarity with Dante networking and DSP configuration via web interface.
