Know before you buy
Yes, with 160 watts per channel at 8 ohms and 300 watts at 4 ohms, this amplifier is designed to handle demanding loads. Its robust power supply and 16 output devices ensure it maintains control even when driving speakers that require significant current.
The dual-mono architecture separates the left and right channels entirely, which significantly reduces crosstalk. This results in a wider, more precise soundstage and improved instrument separation for a more realistic listening experience.
The chassis is built with solid aluminum heatsinks that serve two purposes: they efficiently dissipate heat for stable performance and provide the mass necessary to dampen vibrations. By minimizing mechanical resonance, the amplifier preserves the clarity and detail of your music.
Absolutely. With a wide bandwidth of 5 Hz to 100 kHz and a fast rise time of 2 µs, the IN300 is capable of reproducing the transient detail and frequency range required for high-resolution audio formats.
The unit measures 440 mm wide by 370 mm deep and 130 mm high. Given its weight of 19.5 kg (nearly 43 lbs) and the need for proper ventilation around the heatsinks, ensure your shelf is sturdy and has adequate clearance on all sides.
