QSC CX108V 8 channels, 100 watts/ch at 70V
With this 4-channel CX amplifiers it can give you four channels, without compromising the power, in only two rack spaces. You can choose from three models, two low-impedance versions and a one direct 70 volt model. Each of this model is crafted with exclusive QSC Powerlight™ switching power supply technology to eliminate the hum and noise virtually. The CX Series is the perfect solution because it is designed with high-thermal capacity, high-output power, versatile loading options and unmatched reliability, to any permanently installed sound system. One of this amplifier is QSC CX108V 8 channels, 100 watts/ch at 70V.
Features
- 100 watts per channel at 70 volts
- Compact size—only two rack spaces and 14" deep for reduced rack space
- Channel pairs bridgeable for maximum flexibility
- Exclusive PowerLight switch-mode power supply technology for high performance and compact size
- Active inrush limiting eliminates AC inrush current, removing the need for expensive power sequencers
