Peavey IPS 400 is a professional-grade dual-channel power amplifier designed for commercial sound reinforcement applications. It is well-suited for powering a wide range of loudspeakers in fixed installations, such as restaurants, bars, clubs, and houses of worship.

Each channel of the IPS 400 can deliver up to 200 watts RMS into 4 ohms, or 400 watts RMS into 8 ohms when bridged. This makes it capable of driving even the most demanding loudspeaker loads with ease. The amplifier also features a number of protection circuits to prevent damage from overheating, overcurrent, and short circuits.
