CX-Q 2K4
QSC · Amplifiers
Where passive ceiling speakers are already installed, or specified by the consultant. Two thousand watts allocated across four channels as the room needs it.
Not every room gets new loudspeakers. Where passive speakers are already installed, or the design calls for them, this drives four channels with power allocated flexibly rather than fixed per output.
Why we recommend it
Flexible power allocation
2000 W total across four channels, assigned where the room needs it instead of split evenly.
Any distribution
Low impedance, 70 V or 100 V direct drive on every channel.
Native to QSC
Transport, control and monitoring over Q-LAN, on the same dashboard as the rest of the room.
When you do not need it
If the room uses NL Series PoE loudspeakers, there is no amplifier in the design at all.
