The MONACOR STA-1504 is a robust and highly versatile 4-channel PA amplifier designed for professional audio installations and events where reliable, high-quality sound reinforcement is paramount. Delivering a solid power rating of 4 x 160 W at 4 ohms or 4 x 100 W at 8 ohms, this 3U rack-mountable unit provides exceptional flexibility for driving multiple speaker zones or systems.
Â
Â
The STA-1504 is engineered with professional features to ensure optimal performance and system protection:
Integrated Limiter: Guards your connected speakers by preventing damaging signal peaks and clipping.
Flexible Crossover: Features selectable High-pass and Low-pass filters for each channel, allowing you to fine-tune the frequency distribution for bi-amping or managing different speaker types. The crossover frequency is set at 240 Hz.
Bridgeable Output: Supports 8 ohms bridged operation, providing a powerful output of 2 x 320 W for applications requiring a higher single-channel power load, such as powering subwoofers.
Balanced Inputs: Utilizes 4 x 3-pole XLR, balanced inputs for superior noise rejection and signal integrity over long cable runs.
Secure Adjustments: Level adjustments are tamper-resistant and located on the rear panel to prevent accidental changes after calibration.
Â
Â
Built for demanding environments, the STA-1504 features comprehensive protective circuitry and monitoring:
Comprehensive Protection: Safeguarded against short circuit, overheating, and DC voltage overlay at the outputs for reliable, long-term operation.
Soft Start & Delay: Includes a soft start function and speaker switch-on delay to prevent speaker damage during power-up.
Visual Monitoring: LED VU meters and separate LED clip indicators for each channel allow for real-time performance monitoring.
Cooling: An efficient fan cooling system maintains thermal stability.
Ground Lift: A Ground lift switch helps eliminate hum and noise caused by ground loops.
