Outputs

Wiring connections are shown on the back of the chassis. Carefully note the polarity marks, which are arranged to make Bridge Mode connections easier. Four-channel models are shown in the examples; two-channel models are similar.

OUTPUT TERMINAL SAFETY WARNING! Do not touch output termi- nals while amplifier power is on. Make all connections with ampli- fier turned off. Risk of hazardous energy!

Low Impedance Outputs

Stereo and Parallel Mode- Connect each loudspeaker to its own channel of the amplifier, as shown on the chassis label. The mode configuration switches must be set for Stereo or Parallel mode.

Bridge Mode- Bridge mode configures the channel pair to drive a single high- power loudspeaker load. The mode configuration switches must be set for Bridge mode. Use only the first channel's input and Gain control. Set the second chan- nel's Gain control at minimum.

Distributed Outputs (“V” models, 70V/140V)

Stereo and Parallel Mode- Connect each 70V circuit to its own channel of the amplifier, as shown on the chassis label. The mode configuration switches must be set for Stereo or Parallel mode.

70V Output- Risk of hazardous energy! Class 2 wiring shall be used for 70V outputs.

Bridge Mode- Bridge mode configures the channel pair to drive a single 140V audio circuit. The mode configuration switches must be set for Bridge mode. Use only the first channel's input and Gain control. Set the second channel's Gain control at minimum. Connect the load as shown on the chassis label.

140V BRIDGE MODE PRECAUTIONS:

Class 3 Wiring shall be used for bridged mono 140V outputs.

Connect only 140V distributed audio circuits in bridged mode. Do not use 70V loads in bridge mode! Use Stereo or Parallel mode channels to drive 70V loads. 140V is the minimum for bridge mode operation.

Loads Rated by Model

Be sure the model amplifier you are using is rated for the load!

An asterisk (*)indicates the model is rated for the load. (S/P)= Stereo/Parallel mode (Br.)= Bridge mode

Low Impedance Stereo or Parallel Connection- Each loudspeaker load con- nects to its respective channel. Four channel model shown. Ensure that all speaker connections maintain proper polarity.

EN

Low Impedance Bridge Connection- Each loud- speaker load connects to a bridged channel pair. Four- channel model shown. Check for proper polarity.

70V stereo or parallel connection- Each 70V zone connects to its respective channel. Ensure that all speaker connections maintain proper polarity.

140V Bridge connection- Wire each bridged pair to a 140V circuit as shown.

Check for proper polarity.

QSC Audio has established itself as a leader in professional audio solutions, and their CX series amplifiers, including the CX204V, CX254, and CX404, stand out for their performance and versatility. These amplifiers are specifically designed to meet the needs of commercial audio applications, such as in venues, corporate environments, and educational institutions.

The CX204V is a 2-channel amplifier that delivers 200 watts per channel at 4 ohms, making it ideal for smaller venues or installations that require high-quality audio without overwhelming power. One of its key features is the inclusion of built-in DSP (Digital Signal Processing) capabilities, allowing users to optimize their sound with advanced filtering and equalization options. Additionally, the amplifier supports a range of input options, including balanced XLR and 1/4-inch connectors, providing flexibility for various audio setups.

Moving to the CX254, this 2-channel amplifier boosts power output to 250 watts per channel at 4 ohms, making it suitable for larger spaces that necessitate a bit more oomph. The CX254 also includes QSC’s Power Factor Correction technology, which ensures efficient power usage and greater amplification performance, even during demanding situations. Furthermore, it features RS-232 control capabilities, providing users with remote operation options and making integration into existing audio systems seamless.

The CX404 takes things a step further with its 4-channel configuration, delivering 200 watts per channel at 4 ohms. This amplifier is particularly well-suited for multi-zone applications where audio needs to be distributed across various areas. With its advanced overheating protection and short-circuit protection features, the CX404 is built for durability and reliability, ensuring consistent performance without the risk of damage during extended use.

All three amplifiers in the CX series include QSC's innovative Class D topology, offering lightweight and compact design without sacrificing power or audio quality. The CX series is also distinguished by its robust construction, including a rugged chassis designed to withstand the rigors of installation and performance use.

In summary, the QSC Audio CX204V, CX254, and CX404 seamlessly combine power, efficiency, and versatility, making them ideal choices for a variety of commercial audio applications. Their built-in technologies, advanced features, and solid construction emphasize QSC’s commitment to delivering exceptional sound experiences.
