Technical Description
Here are the technical specifications, taken from NAD official documentation and reliable review sources:
| Specification | Detail |
| Type | Stereo Integrated Amplifier |
| Power Output (Continuous, both channels driven) | 150 W × 2 into 8 Ω; 150 W × 2 into 4 Ω |
| Dynamic / IHF Power | ~ 250 W into 8 Ω; ~ 410 W into 4 Ω; ~ 600 W into 2 Ω for short bursts |
| Power Output in Bridged / Mono Mode | ~ 330 W into 8 Ω (mono/bridged) |
| Total Harmonic Distortion (THD) | ≤ 0.009% at rated power, 20-20 kHz, both channels driven. Some sources list ~0.008%. |
| Signal-to-Noise Ratio (S/N) | ~ 102 dB (A-weighted, ref 1 W)Â |
| Frequency Response | 20 Hz – 20 kHz (at rated power, ±0.1 dB) Extended: –3 dB around 3 Hz to ~70 kHz. |
| Damping Factor | > 200 (at 8 Ω, 50 Hz / 1 kHz) – gives good control over speaker cones. |
| Tone Controls / Bypass | Bass ±8 dB @ 100 Hz; Treble ±5 dB @ 10 kHz; with tone defeat switch. |
| Inputs / Outputs | • Seven line-level RCA inputs (including two tape ins/outs)  • Main-amp input and two pre-amp outputs (useful for adding external power amps or subs)  • Front panel “Media Player†mini-jack input  • Headphone jack (¼-inch) on front panel  • Speaker binding posts (A & B) |
| Protection / Features | Soft Clipping switch; speaker impedance sensing (“PowerDriveâ„¢â€) to safely deliver power depending on load; tone bypass option; IR input/output; 12 V trigger; RS-232 control for integration. |
| Physicals | Dimensions: ~ 435 × 133 × 352 mm (WxHxD)  Weight: ~ 15.3 kg (≈ 33.7 lb) |
| Power Consumption | Idle / typical ≈ 120 W; At rated power consumption ~ 290 W; Standby < 1 W.  |
