Thanks to its Class D technology, this amplifier delivers 4 \u00d7 300 W at 100 V with exceptional energy efficiency and minimal heat generation. The audio spectrum fully covers the 20 Hz\u201320 kHz range with harmonic distortion kept below 0.05% and a signal-to-noise ratio exceeding 100 dB. The temperature-controlled cooling system adjusts its operation to the actual thermal load, ensuring stability and longevity without unwanted noise. <\/p>\n
The smart standby mode detects the absence of a signal for 15 minutes and automatically reduces the amplifier\u2019s power consumption. This continuous monitoring of the audio stream optimizes energy usage without compromising responsiveness: the device instantly returns to normal operation as soon as a signal is detected. A key advantage for controlling long-term operating costs while minimizing environmental impact. <\/p>\n
Each channel has its own volume control and a switchable high-pass filter (Flat\/HPF 80 Hz), accessible only from the rear panel. Euroblock terminal blocks on all connections facilitate wiring and enhance connection reliability. On the front panel, four indicator lights per channel (Signal, -20 dB, Clip, Protect) provide immediate visual feedback. The standard 2U rack-mount chassis houses the electronics in a compact design weighing only 6.7 kg. <\/p>\n
