Power Output & Amplification

• Delivers up to 4,000 W per channel into 4 Ω in linear mode
• Nominal continuous rating is around 2,600 W at 4 Ω per channel
• At 8 Ω, output is roughly 2,000 W per channel
• Bridge operation: two channels bridged deliver elevated wattage into a single load
• Active power factor correction ensures stable operation across a wide mains voltage range

---

DSP Features & Control

• Each channel provides dual-band parametric EQ and adjustable delay (up to 10 seconds)
• Filter types include notch, shelving, and asymmetric designs
• Intelligent load compensation helps optimize performance over long speaker cable runs
• Local control via front-panel color touchscreen and rotary encoder
• Remote access supported via standard audio control protocols and network interface

---

Operational Condition: Low Hours

• Lightly used: estimated operating time between 600 and 1,300 hours
• Consistent with professional, low-wear usage scenarios such as corporate events or light touring
• Internal metrics indicate minimal thermal cycling and low fan usage, suggesting extended service life
