CX 2-Channel Series

The CX 2-Channel Series is designed to meet the specialized needs of sound contractors. Eight models have been designed from the ground up, combining QSC's exclusive PowerLight® technology with specific features to meet the requirements of fixed installations. With high output power, versatile loading options, high thermal capacity and proven reliability, the CX Series is the ideal solution to any permanently installed sound system.

Advanced monitoring and control when used with a Q-Sys or BASIS system. Learn more The model line incorporates QSC's exclusive PowerLight technology. Three models, the CX302V, CX602V and CX1202V, provide direct 70 volt capability ranging from 250 watts to 1000 watts per channel for distributed audio systems. The CX302, CX502, CX702, CX902 and CX1102 offer low impedance capability and range in power from 325 watts to 1100 watts per channel at 4 ohms (20 Hz -20 kHz, 0.05% THD). The versatile CX902 and CX1102 have the ability to drive both 70 volt and low impedance loads for maximum flexibility.

The CX amplifiers are equipped with many contractor specific features including 1 dB detented gain controls for easily repeatable settings and a custom security cover for tamper-proof installations. Active inrush limiting eliminates AC inrush current, cutting the need for power sequencers.

CX amplifiers also include an HD15 Data Port connector to interface with Q-Sys and QSControl networked audio systems, for remote amplifier monitoring and control.

Amplifier Specifications

Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

H
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
> -106 dB
Frequency Response
The range of frequencies the amplifier will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
20 - 20000 Hz
Input Sensitivity
This is the input sensitivity of the amplifier.
1.35 volts
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
0.01%
Voltage Gain
This is the voltage gain of the amplifier measured in decibels.
35 dB
Cooling Options
These are the different cooling systems used in the amplifier to keep it cool.
Cooling Fan
Inputs
These are the type of input connections that the amplifier has.
Euroblock
Outputs
These are the types of output connections that the amplifier has.
