Beschrijving

Features | Crest’s legendary “overbuilt” power supply | Toroidal power transformer | Latest generation of high-speed, wide-bandwidth output devices | Twin tunnel cooling with back-to-front air flow | Dual, variable speed DC fans | Massive, extruded aluminum heat sinks | Balanced XLR and 1/4-inch (TRS) inputs | 5-Way Binding Post Outputs | Stereo/parallel/bridged mono mode selector switch | Ground lift switch | TourClass® protection circuits: | ACL (Active Clip Limiting) prevents speaker damage with gentle gain reduction at clip threshold. | IGM (Instantaneous Gain Modulation) monitors speaker loads to detect conditions that may overstress output devices, allowing safe operation into nominal 2Ω impedances. | AutoRamp gradually increases gain to attenuator setting level when amplifier is turned on. | TourClass also includes comprehensive thermal management, and short circuit, DC voltage, turn-on/off transient, current inrush and sub/ultrasonic input protection. | Input sensitivity selection | Recessed, stepped attenuators | Front panel circuit breaker switch | Modular construction | Specifications | Output Power (1kHz, 0.01% THD+N / 20Hz-20kHz, 0.1% THD+N) | 8Ω Stereo Power: 400W / 350W | 4Ω Stereo Power: 600W / 500W | 2Ω Stereo Power: 750W / 600W | 8Ω Bridged Mono Power:1200W / 1000W | 4Ω Bridged Mono Power: 1500W / 1200W | Max RMS Output Voltage (each channel): 73V | Peak Output Voltage (each channel): 103V | Frequency Response (+0 / -0.3dB, 1W/8Ω): 20Hz-20kHz, -3dB@135kHz | Power Bandwidth (rated power at 4Ω, 1% THD+N): 20Hz-20kHz, -1,1dB/+0dB | TourClass® Protection: ACL, IGM, AutoRamp, short circuit, DC voltage, | turn-on/off transient, current inrush, sub/ultrasonic input. | THD+N (rated power at 4Ω, 1kHz): <0.01% | SMPTE IMD (rated power at 8Ω, 60Hz & 7kHz): <0.01% | Damping Factor (10-400Hz at 8Ω): 400:1 | Input CMRR (1kHz): >-60dB | Input Sensitivity (rated power at 8Ω): 0,775V standard (see table below) | Voltage Gain: X68 standard (see table below) | Input Impedance (balanced/unbalanced): >20kΩ/>10kΩ | Hum and Noise (“A” weighted, full power, 4Ω): 105dB | Crosstalk (“A” weighted, full power, 4Ω): > – 60 dB | Class: H | Input Connectors (per channel): Female XLR (pin 2+, dealer configurable for pin 3+), TRS (tip+) | Output Connectors (per channel): 5-way output binding posts | Filter Storage: 68,000μF | Power Supply (factory configured): 100V-240V, 50-60Hz | Idle Current Draw 220V: 0,8A | 1/8 Power Curr. Draw (typical music, 220V/4Ω): 3A | 1/3 Power Curr. Draw (continuous music, 220V/4Ω): 6,5A | Max Curr.
