The QSC CXD4.5 is the top-tier four-channel processing amplifier in the CXD Series, packing high-density amplification and full loudspeaker DSP into a 2RU chassis. It is aimed at larger installed sound systems, such as auditoriums, houses of worship, sports and entertainment venues, that require substantial power across multiple zones with both low-impedance and 70V/100V distribution.
Key Features
- Four independent channels with Flexible Amplifier Summing Technology (FAST) that reallocates total power across one to four outputs
- Direct 70V/100V constant-voltage drive and low-impedance operation without external transformers
- Onboard DSP: crossovers, parametric EQ, alignment delay, dynamics and Intrinsic Correction for QSC loudspeakers
- PowerLight switch-mode supply with Power Factor Correction
- 20 factory and 50 user presets, front LCD display and GPIO supervision
- Euroblock input and speaker connectors
Delivering up to roughly 7,500 W of total system power, the CXD4.5 replaces racks of separate amplifiers and processors in demanding multi-zone installations.
