Crown Pulse 4×300 4 x 300W 4Ω / 2 x 600W 8Ω

Crown Pulse 4x300 4-channel power amplifier

 

The Crown 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.

Features
• Switch Mode Power Supply delivers great performance without the weight.
• Microprocessor supervision of power sup- plies provides overall system protection.
• Accurate front-panel indicators and level controls.
• Choice of balanced XLR and 1⁄4-inch phone inputs.
Controls: Power switch, bridge mode switches, detented level controls (these may be made tamper-proof).
• Choice of Speakon® and/or binding post outputs.
• Four-channel operation for increased system flexibility.
• All this performance and reliability in only 2 rack spaces.
