Used | Crest - 4001 Amp

This power amplifier is an excellent example of Crest Audio's rich heritage. Reliability, performance, and construction quality are at the foremost of Crest Audio's priorities. The very highest-grade components, combined with industry-standard specifications, make for a versatile amplifier that can be a true workhorse in a number of demanding settings.

• Damping factor: >400, 20Hz-1kHz @ 8Ω
• Slew Rate: 70V/µ
• THD: before clip, 20Hz-20kHz <0.03% at all load impedances. 1kHz THD typically at 0.003% at 8Ω before clip.
• Input Sensitivity: 40x1.27V = full rated power
• Channel Crosstalk: -96dB @ 1kHz/-56dB @ 20kHz.
• Hum & Noise: better than 106dB below full rated output, A-weighted.
• Cooling: forced air, rear-to-front using 106CFM fan. Automatic 2 speed, activates at 55°C.
• Input Connections: 2x ¼"jack bal & unbal, 2xXLR3 locking connectors bal& unbal, screw terminal barrier strip.
• Output connectors: 5 way binding post, screw terminal barrier strip.
• Protection: On/off relay allows PSU stabilization
• DC protect: 8Hz or DC at 3.5V.
• Thermal: channel shutdown at 95°
• Power supply shutdown at 90°
• Surge: circuit protects against high in-rush current peaks at turn-on.
• Current Voltage Limiting: Output transistor protection against short test and high current peak.
• Individual channel load grounding relay.
• Power requirements: 120W min, 3360W max, 1750W average @ 2Ω with musical program.
