Deployment and Installation
To ensure system stability and audio clarity, SKYRS recommends the following professional deployment standards:
Rack Mounting: Use standard 19-inch equipment racks. Ensure that the front rack brackets and rear supports are securely fastened to prevent vibration.
Ventilation: Maintain at least 50mm of clearance around the intake and exhaust vents. Because these units use forced air cooling, avoid installing them in sealed, non-ventilated cabinets.
Cabling: Use high-quality shielded cabling for inputs to minimize noise floor interference. For outputs, use 10 AWG speaker cable to maintain signal integrity over long distances.
Electrical Safety: These amplifiers include an in-rush current limiter, but for multi-amplifier installations, ensure the facility’s AC distribution is sized to handle the aggregate power consumption (660VA to 1800VA depending on the load).
Configuration and Optimization
Configuration is managed during the setup phase by SKYRS technical staff to align the amplifiers with your specific audio environment:
Operation Modes: The rear panel features a mode switch to select between Stereo, Parallel (mono-in, dual-out), or Bridged-Mono for high-power subwoofer or large-array requirements.
Input Level Control: Utilize the high-quality, stepped “Alps” attenuators on the front panel for precise gain staging. These can be recessed to prevent unauthorized adjustments.
Security: Use the provided attenuator security covers to lock in settings once the system has been calibrated, preventing accidental changes in public or multi-user spaces.
Status Monitoring: Train staff to monitor the front-panel LED indicators (Signal, Peak, Protect, and Attenuator Bypass) to ensure the system is operating within safe thermal and voltage limits.
