Ahuja XDA-5002 Dual Channel Class D Power Amplifier

🔊 Key Features & Performance

• Dual‑channel output:

  • Stereo/mono mode: 8 Ω → 1100 W + 1100 W, 4 Ω → 1800 W + 1800 W RMS

• Ultra-low distortion: THD + N < 0.1 %; flat frequency response of 20 Hz–20 kHz (±1 dB)

• Built-in Low‑Pass filters: switchable to 80 Hz or 120 Hz @ 24 dB/oct, ideal for subwoofer use

• Selectable input sensitivity: 0 dBu (775 mV) or 4 dBu (1.23 V)

• High fidelity electronics: SNR > 100 dB; channel separation > 65 dB; damping factor > 1000; slew rate 20 V/μs

🛡️ Protection & Safety

• Comprehensive protection system includes thermal, DC offset, radio-frequency filtering, short-circuit, overload, over-voltage, and clip monitoring

• Front panel and AC safeguards: 15 A circuit protector and dual 16 A DC fuses

• Configurable limiter (ON/OFF) to prevent clipping distortion; “Limiter ON” keeps output clean, “Limiter OFF” suits subwoofer use

🔌 Connectivity & Controls

• Inputs: 2× XLR (balanced) + 6.3 mm stereo jack (unbalanced)

• Outputs: 4‑way Speakon and binding posts per channel

• Operating modes: slide switch on rear panel for stereo or mono bridging

• Front‑panel controls: 2× 41-step level attenuators with LEDs for signal, clip, temperature, and protection statuses

🧰 Design & Build

• Efficient Class D topology with toroidal power transformer, all enclosed in a compact 2U rack unit

• Active cooling: twin temperature‑sensing fans for precision thermal management

• BIS certified for safety compliance in India

• Chassis: W482 × H104 × D438 mm; weight ~21.5 kg

• Power draw: ~5500 VA @ 220–240 V, 50/60 Hz
