The QSC CXD4.3 is a four-channel processing amplifier from the CXD Series, combining high-density amplification with full loudspeaker DSP in a 2RU chassis. It targets installed sound applications, such as retail, restaurants, worship and mid-size venues, where an integrator wants one box to power multiple zones with both low-impedance and 70V/100V loudspeaker lines.
Key Features
- Four independent channels with Flexible Amplifier Summing Technology (FAST) to distribute power across one to four outputs
- Direct 70V/100V constant-voltage drive plus low-impedance operation, no output transformers needed
- Onboard DSP: crossovers, parametric EQ, alignment delay, dynamics and Intrinsic Correction voicings for QSC loudspeakers
- PowerLight switch-mode supply with Power Factor Correction
- 20 factory and 50 user presets, front LCD display and GPIO
- Euroblock input and speaker connectors
The CXD4.3 delivers up to roughly 5,000 W of total system power, eliminating outboard processors and simplifying multi-zone installations.
