Answer:
The Ahuja DPA-770M delivers 75W RMS (100W Max.) power output across a 50 Hz to 15,000 Hz (±3 dB) frequency response with a 55 dB S/N ratio. It provides output taps for 4Ω, 8Ω, 16Ω, and 100V distributed lines, measures 38.5 x 4.9 x 10.6 cm, and weighs 4.5 kg.
The Ahuja DPA-770M is an industrial and commercial medium-wattage public address mixer amplifier engineered to the following technical parameters:
- Power Output: 100W Max., 75W RMS at 10% THD, and 70W RMS at 5% THD.
- Frequency Response: 50 Hz to 15,000 Hz ±3 dB with a Signal-to-Noise (S/N) Ratio of 55 dB.
- Input Channels: 4 × Microphone inputs (0.6 mV / 4.7 kΩ) and 1 × Auxiliary input (100 mV / 330 kΩ).
- Speaker Output Terminations: Low-impedance taps at 4Ω, 8Ω, and 16Ω, plus high-impedance 100V line distribution.
- Preamp Line Output: 1V / 3.5 kΩ for routing signal to auxiliary booster amplifiers.
- Tone Shaping: Active Bass control (-10 dB to +7 dB at 100 Hz) and Treble control (-10 dB to +7 dB at 10 kHz).
- Visual Monitoring: Integrated 5-LED output level array.
- Power Supply Requirements: Dual-mode AC 220–240V (50/60 Hz, 140–170 VA) and DC 12–14V car battery (they are not included) drawing up to 3A.
- Physical Dimensions & Weight: 38.5 × 4.9 × 10.6 cm; 4.5 kg.
