\Product Details\
\ \
\ The new CMXa series is an economical and robust power amplifier, developed to meet the needs of system integration.\
\ \
\ \
\ \
\ The proven and highly reliable power amplifier platform CMXa power amplifier integrates QSC''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s more than 40-year trouble-free design concept, delivering strong power while avoiding the impact of failure. These amplifiers are designed to use power components that we have. CMXa uses a toroidal transformer with high redundancy capability and high current tolerance, with a filter circuit to ensure sufficient energy supply capability. The CMXa power amplifier integrated with advanced crystal amplifier components can output high-level capabilities, even when used in 2 ohm low-impedance situations.\
\ \
\ \
\ \
\The output part of the power amplifier is characterized by the use of a sturdy and stable AB and H class amplifying structure. The high efficiency of Class H can reduce the dependence on AC power supply and can effectively reduce the overall heat energy.\
\ \
\ \
\ \
\All CMXa power amplifiers have short-circuit output protection circuits. The current is automatically limited to protect the power amplifier from short-circuit damage until the circuit returns to normal.\
\ \
\ \
\ \
\The CMXa power amplifier also has DC protection, even when the crystal component fails or fails, it can prevent the speaker system from being damaged by the DC signal. Outstanding performance\
\ \
\ \
\ \
\CMXa power amplifier can restore real and accurate broadcast-level audio quality. The complementary output circuit uses advanced linear devices to restore accurate and flatTan''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s frequency response. SMT(Surface mount technology)The circuit is only 1/3 of the volume of the conventional circuit, which can meet the demand for high-power output under the volume of a 2U cabinet(CMX2000Va3U volume). Different from other product designs, the heat sink is directly attached to the CMXa output circuit. The tight coupling provides heat dissipation efficiency and brings more powerful cooling.ability.\
\ \
\ \
\ \
\There are four models in the CMXa series to choose from. 3 2U rack space products, power coverage from 300 watts to 800 watts(At 4 ohms per channel). One 3U rack spaceThe model provides 2500 watts 2 ohms per channel. All four models are only 16” depth.\
\ \
\ \
\ \
\Each model with "V" means that it has a voltage output of 70 or 100V, which can meet the driving needs of a distributed speaker system. CMX300Va and CMX500Va must be configured in bridge mode, using M o n o form to drive the post-stage high impedance system. The CMX800Va and 2000Va can drive high-impedance speakers in both Mono and dual-channel modes.\

\ \
\ \
\Parameter details\
\ \
\ \
\ \
\ "Flexible matching" different load requirements, allowing to drive loads as low as 2 ohms, and can also drive 70/100V constant voltage speaker systems.\
\ \
\ \
\ \
\ “ Flexible choice” Input terminal, optional XLR, binding post or TRS input form\
\ \
\ \
\ \
\ "Flexible and easy to use" output terminal configuration, optional NL4 SpeakonTM or bar output terminal\
\ \
\ Cabinet installation depth is less than 40.6mm\
\ \
\ \
\ \
\ 1dB gain step, gain knob with stop damping setting, can adjust gain quickly, accurately and conveniently\
\ \
\ \
\ \
\ Gain cover design to prevent accidental touch of gain knob\
\ \
\ The back panel DIP switch design makes it easy to choose stereo, parallel or bridge mode. Low-cut filter or dynamic limiter can be enabled or disabled\
\ \
\ \
\ \
\ \
\ Low noise variable speed fan, exhaust air from back to front, keep the inside of the cabinet cool\
