AMP4300

The AMP4300 amplifier delivers 4 × 300 W in-line 70/100 V for medium- to large-scale installations requiring power and multi-zone control.
Shopping centers, sports complexes, commercial buildings: as soon as the sound surface expands and power requirements increase, this multi-channel amplifier is the natural choice. Its four 300 W channels can supply multiple zones with sound levels adapted to each space. The Class D design combines high power with a small thermal footprint, while rear-mounted controls ensure that only installers retain control over 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 low heat emission. The audio spectrum covers the entire 20 Hz-20 kHz range, with harmonic distortion kept below 0.05% and a signal-to-noise ratio in excess of 100 dB. The thermostatically-controlled fan adapts its speed to the actual thermal load, ensuring stability and longevity without parasitic noise.

Automated power management
Intelligent standby mode detects the absence of signal for 15 minutes and automatically reduces the amplifier’s power consumption. This continuous monitoring of the audio flow optimizes energy expenditure without compromising responsiveness: the device instantly resumes nominal operation as soon as a signal is present. A decisive advantage for controlling long-term operating costs while limiting environmental impact.

Integrated installer configuration
Each channel has its own volume control and switchable high-pass filter (Flat/HPF 80 Hz), accessible only from the rear panel. Euroblock terminals on all links facilitate wiring and enhance connection reliability. On the front panel, four LEDs per channel (Signal, -20 dB, Clip, Protect) provide immediate visual diagnostics. The standard 2U rack chassis houses the electronics in a compact format weighing just 6.7 kg.
