Know before you buy
With 160 watts per channel at 8 ohms and 300 watts at 4 ohms, this amplifier has the power to drive almost any speaker, including demanding floor-standing models. Its high current capacity ensures it maintains control and dynamics even with speakers that have complex impedance curves.
Yes, it includes a dedicated BY-PASS input. This allows you to integrate the amplifier into a home theater system by letting an external processor control the volume for the front channels.
The double mono architecture separates the electrical stages for the left and right channels, which significantly reduces crosstalk. This results in a wider, more precise soundstage and better instrument separation compared to shared-circuit designs.
Absolutely. The chassis features lateral aluminum fins specifically designed for efficient heat dissipation, and the robust power supply ensures the unit remains stable and consistent during extended use.
This large capacitor bank acts as an energy reservoir, allowing the amplifier to respond instantly to sudden musical transients. It ensures the power delivery remains clean and punchy, preventing the sound from thinning out during complex or bass-heavy passages.
Yes, the provided global remote control is designed to operate the IN400SE as well as other compatible Atoll electronics, helping you manage your system with a single handset.
