The Ashly NX1.54 Programmable Output Power Amplifier is designed for professional audio applications. It offers per channel output power of 1,500 W at 2 Ω, 1,500 W at 4 Ω, and 1,250 W at 8 Ω. The amplifier also supports bridge mode with 3,000 W at 4 Ω. It includes 70 V and 100 V output options. Power draw specifications include sleep mode under 1 W, standby mode 70 W, and idle mode 100 W. Current draw varies based on voltage input. Thermal dissipation is listed in BTU/hr for different modes. Voltage gain can be set to 26 dB, 32 dB, 38 dB, or 1.4 V. Damping factor exceeds 250 with an 8 Ω load. A high-pass filter at 80 Hz is included. Distortion levels are below 0.5% THD-N and THD. Channel separation is -75 dB at 1 kHz. Signal to noise ratio is over 111 dB from 20 Hz to 20 kHz. Frequency response is +/-0.05 dB across the same range. Input connectors include balanced Euroblock 3.5 mm, 1/4" TRS, and XLR combo jack.
