C-Audio Pulse 4X300 Amplifier

The C-Audio Pulse 4×300 is a 4-channel power amplifier producing 300W per channel into 4Ω or 170W per channel into 8Ω. The Pulse 4×300 is ideal for powering monitor wedges on a small stage. The Pulse 4×300 can also be bridged, producing 2 x 600W at 8Ω or 2 x 660W at 4Ω.
