Product Overview

Overview

The QSC CX-Q 4K8 is a 2RU network power amplifier with eight output channels and 4,000 W of total capacity. Eight channels let it feed a whole floor of zones from one box: Q-SYS lists up to 1,000 W on a channel at 70 V, 100 V, 8 ohms and 4 ohms, with channels able to be paired, bridged or paralleled when a zone needs more. Eight mic/line inputs with phantom power come in alongside the Q-LAN audio, and the Qn version of the series takes network audio only.

Frequently Asked Questions

What is the QSC CX-Q 4K8?
The QSC CX-Q 4K8 is a 2RU network power amplifier with eight output channels and 4,000 W of total capacity. Eight channels let it feed a whole floor of zones from one box: Q-SYS lists up to 1,000 W on a channel at 70 V, 100 V, 8 ohms and 4 ohms, with channels able to be paired, bridged or paralleled when a zone needs more. Eight mic/line inputs with phantom power come in alongside the Q-LAN audio, and the Qn version of the series takes network audio only.
How does the CX-Q 4K8 differ from the CX-Q 4K4?
The 4K8 has eight channels and eight inputs against four, for the same 4,000 W total, so each zone gets less guaranteed power but there are twice as many zones.
What is the difference between the Q and Qn models?
Q-SYS notes that Q models have 3-pin Euro analog inputs as well as Q-LAN network audio, and Qn models have network audio only. This page covers the CX-Q 4K8 as listed in the catalogue; Corporate AV confirms the variant at quote stage.
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.
How good are the noise figures?
Unweighted noise is better than 101 dB and weighted better than 104 dB, with frequency response of 20 Hz to 20 kHz within 0.3 dB.
How big is it?
A 2RU unit, 89 x 482 x 406 mm, weighing 11.3 kg net, on a 100 to 240 VAC universal supply.
