Introducing the Xcelsus Definio 4, a full range digital amplifier engineered to elevate your audio experience. This exquisite model comes with four channels, ensuring a versatile performance. The Definio 4 is capable of delivering a robust 105 watts of power at 4 Ohms (RMS), and a remarkable 165 watts at 2 Ohms (RMS). When bridged, the power at 4 Ohms (RMS) escalates to an impressive 320 watts, revealing the true prowess of this amplifier.

With a signal to noise ratio of 90 dB (A-weighted) and a damping factor exceeding 100, the Xcelsus Definio 4 ensures a pristine audio output devoid of unwanted noise and distortion. The total harmonic distortion (THD) is kept under 0.02% at 5W, 1 kHz, which is a testament to the clean and clear audio performance this unit promises.

The expansive frequency response from 10 Hz to 40 kHz captures every nuance of the sound, delivering a rich and immersive auditory experience. Adjustability is at your fingertips with high-pass and low-pass filters, ranging from 50 to 500 Hz, allowing for a tailored sound output according to your preferences.

The input impedance stands at 5 kohm for low-level inputs, with an input sensitivity range of 0.2 to 6 V, ensuring a compatible and efficient connection with your audio sources. Even at idle, the Definio 4 is energy-efficient with a power consumption of 0.7 A, which drops down to 0.35 A. Under maximum operation, the power consumption is capped at 64 A (35 A), making it a reliable choice for continuous performance.

For safety and seamless operation, it is advised to use an external fuse rated at 60 A (40 A). Powered by a 12 Volt supply, the Xcelsus Definio 4 is not only a powerhouse of performance but a statement of quality and reliability in amplifying your audio experience.
