Description
The new 4-channel CX amplifiers give you four channels in only two rack
spaces-without compromising on power. Choose from three models-a direct
70-volt model and two-low impedance versions-each equipped with our
exclusive PowerWave switching power supply technology to virtually
eliminate noise and hum. With high output power, versatile loading
options, high thermal capacity and unmatched reliability, the CX Series
is the perfect solution to any permanently installed sound system.
With PowerWave technology, CX amplifiers take your sound to a whole new
level. Not only does it give you tighter bass and clean transparent
highs, PowerWave also cuts waste heat, boosts reliability and gets rid
of unwanted noise and hum. PowerWave is a revolutionary switching power
supply technology that provides ample current to the audio power
circuitry by charging the supply rails 230,000 times a second through an
ultra-low impedance circuit. So unlike amplifiers that use conventional
supplies, the audio signal is never starved prematurely and remains
crisp and clean.
Features:
- Three models that range in power from 170 watts to 450 watts per
channel
- Compact size-all models only 2 RU and 14" deep for reduced rack
cost and floor space
- Channels 1&2 and 3&4 bridgeable for maximum flexibility
- Active Inrush Limiting eliminates AC inrush current, removing
the need for expensive power sequencers
- HD15 DataPort connector for QSControl computer control
- 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 PowerWave 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 (33 Hz or 75 Hz on non-V models, 50 Hz or 75 Hz on V
models)
- Comprehensive front panel indicators including signal, clip,
protect and QSC's exclusive bridge-mono and parallel-input LEDs
- 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
- Light weight-all models only 21 pounds (9.5 kg) for easier
racking and shipping
- 3-year warranty plus optional 3-year extended service contract
