The QSC CX204V is a four-channel, 70V direct-distribution, transformerless power amp for fixed installation

Ever since QSC founders Pat Quilter and Barry Andrews started out making guitar amps, and later power amps, in the back of a music shop in Costa Mesa, CA, they dedicated themselves to quality and reliability. That’s why QSC is the leader in power amplification and the reason system integrators choose QSC CX-series amplifiers for fixed installation. The SC204V is a transformerless, high-voltage power amp that offers direct 70-volt power distribution, which provides the advantage of connecting numerous speakers without concern for impedances, or designing complicated parallel and serial wiring schemes. The CX204V is equipped with QSC’s exclusive PowerLight™ switching power supply, which virtually eliminates noise and hum.

QSC CX204V 4-channel, 70V power amplifier in one take:

  • Compact size — only 2 RU and 14″ deep for reduced rack cost and floor space
  • Bridgeable channels 1 + 2 and 3 + 4, for maximum flexibility
  • Active inrush limiting eliminates AC inrush current, removing the need for expensive power sequencers
  • HD15 DataPort connector for Q-SYS networked control and monitoring
  • Custom integrated security cover for tamper-proof installations
  • Variable-speed fan for low noise
  • 1-dB detented gain controls for fast and accurate gain settings
  • Detachable Euro style input connectors
  • DIP switch control for clip limiters, high pass filters, bridge mono and parallel operation
  • Exclusive PowerLight switch-mode power supply technology for high performance and compact size
  • Selectable high-pass filters protect speakers and prevent speaker transformer saturation with minimal effect on program material (50 Hz or 75 Hz)
  • Comprehensive front panel indicators including signal, clip, protect and QSC’s exclusive bridge mono and parallel input LEDs
  • Integrated security cover for tamper-proof installations
  • Barrier strip output connector
  • Comprehensive protection circuitry including DC, infrasonic, thermal overload and short circuit protection
  • High-performance Class AB+B complementary bipolar output circuitry
  • Lightweight—all models only 21 pounds (9.5 kg) for easier racking and shipping
  • 3-year warranty plus optional 3-year extended service contract
  • All CX Series amplifiers meet the European Union’s, 2006 RoHS directive to restrict the use of hazardous materials used in electronic devices.

INSIDE THE BOX—QSC CX204V

Designed for installation applications requiring premium sound quality and high output, QSC CX power amplifiers are recognized by sound contractors worldwide for their reliability. CX 4-channel amplifiers feature QSC’S PowerLight power supply technology, which reduces weight, eliminates AC mains hum and improves audio quality. The highly efficient power supply also draws less power and produces less heat, resulting in added energy savings. The CX204V also feature advanced amplifier control and monitoring via the Q-SYS™ network audio platform.

Direct 70V for large installation

Direct 70V power offers several advantages over traditional low-impedance amplifiers, particularly for integration in large facilities. To begin with, 70V systems (US and Canada) enables you to connect large numbers of speakers without the need to design complex connection schemes or concerns over speaker impedance. 70V systems don’t restrict you to a fixed configuration. They’re easy to expand, plus they let you use smaller gauge cable, which is easier to run through physical space and less expensive as well. Another advantage of continuous voltage systems is the ability to play different volume levels in various listening areas using just a single amplifier. Direct, or continuous voltage systems, such as the CX204V, also allow easy remote volume adjustment. A passive volume control can be installed to provide level control over a single speaker or a multiple-speaker zone.

OUTSIDE THE BOX—QSC CX204V

Featuring QSC’s customary boat-anchor build quality, the front panel of the CX204V has a power switch; four gain controls; cooling air exhaust vents; LED indicators for each channel that display signal, level, and clipping; bridge and parallel mode LED indicators; power indicator; and security panel slots and retaining screw. The CX204V includes an integrated security cover to prevent wandering fingers from changing settings.

The rear panel has terminal block input connectors, dual data ports, DIP mode switches with setting diagrams, barrier strip output connectors, cooling air inlet vents, and IEC power connector.

With high-output power, versatile loading options, high-thermal capacity, and QSC’s renowned reliability, the CX204V is the perfect solution to any permanently installed sound system. For more information, call or chat online with your Westlake Pro Sales Consultant today.
