Welcome to Midwest Pro Sound and Lighting

The CA12 professional power amplifier is designed to achieve unsurpassed sonic performance and long-term reliability--even when operating under extreme stress--in touring or fixed installation applications.

• 650/700W @ 8 ohms
• 1100/1200W @ 4 ohms
• 1100/1400W @ 2 ohms
• Bridged 2200/2400W 2200/2800W
• Balanced XLR and ¼-inch (TRS) inputs
• Crest Audio's legendary "overbuilt" power supply
• Toroidal power transformer
• Latest generation of high-speed, wide-bandwidth output devices

• TourClass protection circuits: o ACL (active clip limiting) prevents speaker damage with gentle gain reduction at clip threshold
• IGM (instantaneous gain modulation) monitors connected loads to detect conditions that may overstress output devices, allowing safe operation into nominal 2 ohm impedances
• AutoRamp gradually increases gain to attenuator setting level when amplifier is turned on
• TourClass also includes comprehensive thermal management; 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
• Five-year manufactuer warranty
