4. Setup

1. Placement: Ensure the amplifier is placed in a well-ventilated area, preferably in a standard 2U rack space. Maintain adequate clearance around the unit for airflow.
2. Power Connection:
   • Ensure the amplifier's power switch is in the OFF position.
   • Connect the supplied AC power cord to the AC Inlet on the rear panel and then to a suitable grounded power outlet.
3. Input Connections:
   • Connect your audio source (mixer, preamplifier, etc.) to the CH1 INPUT and CH2 INPUT XLR connectors on the rear panel using balanced XLR cables.
   • If linking to another amplifier, use the CH1 LINK and CH2 LINK XLR outputs.
4. Output Connections (Speakers):
   • Connect your speakers to the appropriate speaker output terminals (binding posts or Speakon) on the rear panel. Ensure correct polarity (+ to + and - to -).
   • For 70V systems, ensure your speakers are compatible with 70V constant voltage systems and connect them accordingly.
   • For 4Ω or 8Ω operation, ensure your speakers' impedance matches the amplifier's output capabilities for the selected mode (Stereo or Parallel).
   • For Bridged mode (BRG), connect a single speaker to the designated BRG output terminals. Refer to the rear panel markings for correct connections.
5. Mode Selection:
   • Set the BRG/PARALLEL/STEREO switch to your desired operating mode.
   • Set the HI-PASS switches according to your system requirements. "OFF" for full range, "30Hz" or "50Hz" to filter out low frequencies.

5. Operating Instructions

1. Power On:
   • Before powering on, ensure all level controls (CHA, CHB) are set to their minimum position.
   • Turn on your audio source equipment first.
   • Flip the Power Switch on the front panel to the ON position. The LCD display will illuminate.
2. Adjusting Volume:
   • Slowly increase the CHA and CHB level controls to achieve the desired output volume.
   • Monitor the LCD display for volume levels (in dB) and operating temperature.
3. Using the LCD Display and Navigation:
   • Use the "Home", "Level", "Type", "Function", and "Mute" buttons to navigate through the amplifier's settings and monitoring options displayed on the LCD.
   • Consult the on-screen menus for specific adjustments related to input sensitivity, output modes, and other advanced features.
4. Power Off:
   • Before powering off, reduce all level controls to their minimum position.
   • Turn off the amplifier using the Power Switch.
   • Turn off your audio source equipment.

6. Maintenance

• Cleaning: Disconnect the amplifier from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Do not use liquid cleaners or aerosols.
• Ventilation: Regularly check that ventilation openings are clear of dust and debris to ensure proper cooling.
• Cable Connections: Periodically inspect all cable connections for secure fit and signs of wear.
• Storage: If storing the amplifier for an extended period, ensure it is in a cool, dry place, protected from dust and extreme temperatures.
