Know before you buy
With 1,125 watts into 8 ohms and high current capability, this amplifier is designed to drive even the most demanding, power-hungry floor-standing speakers with ease. Its stability at low impedances makes it an excellent choice for speakers that typically dip to 4 ohms or lower.
ICEedge technology is designed to provide high efficiency without the harshness often associated with older Class D designs. It delivers a clean, neutral, and virtually noise-free output that maintains high fidelity even at the extreme power levels this unit is capable of.
Yes, the i-V1 ULTRA is versatile and includes both fully balanced XLR inputs and single-ended RCA inputs to accommodate a wide range of audio setups.
The unit is equipped with built-in short circuit and thermal protection. These systems automatically monitor the amplifier's status to prevent damage during operation, ensuring long-term reliability.
The amplifier features a triggered On/Off function, allowing it to automatically power up or enter standby mode when it receives a signal from your compatible preamplifier or processor.
Because it is a monoblock design, it is highly flexible for both applications. You can use one for a dedicated stereo setup or add multiple units to power a high-performance home theater system where each channel requires significant, independent power.
