Product Overview

Overview

The QSC CX-Q 4K4 is a 2RU network power amplifier with four output channels and 4,000 W of total capacity. It is the middle of the 4-channel CX-Q line: enough power per channel to drive 70 V or 100 V lines directly, with channel power that can be shared between outputs, four mic/line inputs with phantom power, and a Q-LAN network port that brings audio straight from Q-SYS. A front screen shows channel set-up and eight bi-directional GPIO lines connect control gear.

Frequently Asked Questions

What is the QSC CX-Q 4K4?
The QSC CX-Q 4K4 is a 2RU network power amplifier with four output channels and 4,000 W of total capacity. It is the middle of the 4-channel CX-Q line: enough power per channel to drive 70 V or 100 V lines directly, with channel power that can be shared between outputs, four mic/line inputs with phantom power, and a Q-LAN network port that brings audio straight from Q-SYS. A front screen shows channel set-up and eight bi-directional GPIO lines connect control gear.
How much power does the CX-Q 4K4 deliver?
Q-SYS's power table lists up to 1,000 W on a channel at 70 V, 100 V and 8 ohms and up to 1,500 W at 4 ohms in independent mode, with bridged and paralleled modes rising further. The 4,000 W in the name is the total the amplifier can supply, shared across the channels.
What does FlexAmp mean?
FlexAmp with FAST (Flexible Amplifier Summing Technology) lets channels share power and be bridged or paralleled, so a loudspeaker line that needs more current can draw from the spare capacity of its neighbours.
Does it need a Q-SYS core?
Like other native Q-SYS devices, a CX-Q needs a Q-SYS core on the network before it can be set up or used.
What distortion and noise figures does it have?
Typical distortion is 0.02 to 0.05% at 8 ohms, frequency response is 20 Hz to 20 kHz (+0.2 / -0.7 dB), and unweighted noise is better than 102 dB below full output.
What size and weight is it?
It is a 2RU unit, 89 x 482 x 406 mm, weighing 11.3 kg net, and runs from a 100 to 240 VAC supply.
Can Corporate AV supply and install the QSC CX-Q 4K4 in India, and how do I get a quote?
