The QSC CXD4.5Q is the flagship four-channel network processing amplifier in the CXD-Q Series, purpose-built to plug directly into a Q-SYS ecosystem over a Q-LAN Ethernet network. It is aimed at systems integrators handling demanding installed AV projects such as houses of worship, stadiums, theaters and large retail, where a single rack unit must feed several loudspeaker zones with onboard DSP and network audio in one box.
Key Features
- Four independent channels with Flexible Amplifier Summing Technology (FAST) that redistributes total power across one to four outputs
- Native Q-SYS integration via Q-LAN for audio transport, control and monitoring
- Direct 70V/100V constant-voltage drive plus low-impedance operation, no external transformers required
- Class-D output with a PowerLight switch-mode supply and Power Factor Correction
- Onboard loudspeaker DSP and GPIO for system supervision
- Compact 2RU chassis with multi-stage sleep mode for energy savings
Note: this model has been discontinued by QSC but remains in service and available through resale channels.
