เครื่องขยายเสียง ยี่ห้อ QSC รุ่น CX108V
คุณสมบัติ
- 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
- Four HD15 DataPort connectors (one per channel pair) for Q-SYS networked control and monitoring
- Custom integrated gain control security cover for tamper-proof installations
- 1-dB recessed detented gain controls for fast and accurate settings
- Detachable Euro-style input and output connectors
- DIP switch control for clip limiters, high-pass filters, bridge mono and parallel operation
- 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, bridge mono and parallel input LEDs
- Fully protected—including DC, infrasonic and ultrasonic, thermal overload and short circuit protection
- High-performance Class AB+B complementary bipolar output circuitry
- Lightweight—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.
