3. Setup

3.1 Unpacking and Inspection

Upon receiving your Behringer Ultra-Drive Pro DCX2496, carefully unpack the unit and inspect it for any signs of damage that may have occurred during transit. If you find any damage, contact your dealer immediately.

The package should contain the following items:

• Behringer DCX2496 Loudspeaker Management System
• Power Cable
• User's Manual (this document)

3.2 Rack Mounting

The DCX2496 is designed for standard 19-inch rack mounting. Ensure adequate ventilation around the unit to prevent overheating. Do not block the ventilation slots.

3.3 Connections

Before making any connections, ensure the unit is powered off. Use high-quality, balanced XLR cables for optimal audio performance.

• Analog Inputs (A, B, C): Connect your audio sources (e.g., mixer outputs) to these XLR inputs. Input C can also accept a digital stereo AES/EBU signal.
• Analog Outputs (1-6): Connect these XLR outputs to your power amplifiers, which then drive your loudspeakers.
• Power Connection: Connect the supplied power cable to the AC inlet on the rear panel and then to a suitable power outlet.
• RS-232/RS-485: For remote control via PC, connect a serial cable to the appropriate port.

Note: Always ensure proper grounding to avoid hum and noise.
