4. Setup Guide

4.1. Unpacking and Placement

Carefully remove the amplifier from its packaging. Place the amplifier in a well-ventilated area, ensuring adequate airflow around the unit. Avoid placing it near heat sources or in direct sunlight. The CDi 6000 is designed for rack mounting; ensure proper rack ventilation if installed in an equipment rack.

Connect the supplied AC power cord to the amplifier's power inlet and then to a grounded AC power outlet. Ensure the power source matches the amplifier's voltage requirements (140 Volts).

4.3. Input Connections

Connect your audio source (e.g., mixer, preamplifier) to the amplifier's input connectors. The CDi 6000 typically uses balanced XLR or Phoenix-style connectors for audio inputs. Refer to the rear panel diagram for specific input locations.

4.4. Output Connections

Connect your loudspeakers to the amplifier's output terminals. The CDi 6000 supports various speaker configurations (2Ω, 4Ω, 8Ω, 70V, 140V). Ensure correct polarity and impedance matching for optimal performance and to prevent damage to the amplifier or speakers. Use appropriate gauge speaker wire for your setup.
