AMP4300

The AMP4300 amplifier delivers 4 × 300 W in a 70/100 V line for your medium- and large-scale installations requiring power and multi-zone control.
Shopping centers, sports complexes, commercial buildings: whenever the coverage area expands and power requirements increase, this multichannel amplifier is the natural choice. Its four 300-watt channels allow you to power multiple zones with sound levels tailored to each space. The Class D design combines high power with a low thermal footprint, while the rear-panel controls ensure that only installers have access to critical settings.

Controlled power, minimal heat.
Thanks to its Class D technology, this amplifier delivers 4 × 300 W at 100 V with exceptional energy efficiency and minimal heat generation. The audio spectrum fully covers the 20 Hz–20 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.

Automated Energy Management.
The smart standby mode detects the absence of a signal for 15 minutes and automatically reduces the amplifier’s 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.

Integrated installer setup.
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.
