The rear panel provides all necessary connections for integrating the 8300XP into your audio system:

  • Balanced XLR Inputs (Left/Right): For connecting sources with balanced outputs, offering superior noise rejection.
  • Unbalanced RCA Inputs (Left/Right): For connecting sources with unbalanced outputs.
  • Speaker Outputs (Left/Right): High-quality binding posts for connecting your loudspeakers. Ensure correct polarity (+ to + and - to -).
  • Bridge Mode Switch: A switch to select between Stereo and Bridged (Mono) operation. When in bridged mode, only use the designated input and speaker terminals.
  • 12V Trigger In/Out: Allows for remote power control with other compatible components.
  • AC Power Inlet: For connecting the supplied AC power cord.

5. Setup

5.1 Placement

Place the 8300XP on a stable, level surface away from direct sunlight, heat sources, and excessive moisture. Ensure there is adequate space around the unit for ventilation, especially above and behind it.

5.2 Connecting Speakers

  1. Ensure the amplifier is turned off and unplugged from the mains power.
  2. Connect your loudspeakers to the corresponding speaker output terminals on the rear panel.
  3. For stereo operation, connect the left speaker to the 'LEFT' terminals and the right speaker to the 'RIGHT' terminals. Ensure the positive (+) terminal on the amplifier connects to the positive (+) terminal on the speaker, and similarly for the negative (-) terminals.
  4. For bridged (mono) operation, set the 'BRIDGE' switch to 'ON'. Connect your single speaker to the designated bridged output terminals (refer to the markings on the rear panel).

5.3 Connecting Audio Sources

  1. Connect your pre-amplifier or audio source to either the Balanced XLR Inputs or Unbalanced RCA Inputs. Do not use both simultaneously for the same channel.
  2. If using balanced connections, ensure the XLR cables are securely connected.
  3. If using unbalanced connections, ensure the RCA cables are securely connected.

5.4 Power Connection

  1. Once all audio and speaker connections are made, connect the supplied AC power cord to the AC inlet on the rear panel of the amplifier.
  2. Plug the other end of the power cord into a suitable mains power outlet.

6. Operating Instructions

6.1 Powering On/Off

  1. To power on the amplifier, press the Power button on the front panel. The power indicator LED will illuminate.
  2. To power off the amplifier, press the Power button again. The power indicator LED will turn off.

6.2 Stereo vs. Bridged Mode

The 8300XP can operate as a two-channel stereo amplifier or a single-channel monoblock amplifier (bridged mode).

  • Stereo Mode: For typical two-channel audio systems. Ensure the 'BRIDGE' switch on the rear panel is set to 'OFF'.
  • Bridged Mode: For higher power output to a single speaker. Ensure the 'BRIDGE' switch on the rear panel is set to 'ON'. When in bridged mode, use only the designated input (typically the Left channel) and the specified bridged speaker terminals. Consult the rear panel markings for precise connections.

Caution: Ensure the amplifier is powered off before changing the Stereo/Bridge mode switch to prevent damage to the amplifier or speakers.

7. Maintenance

  • Cleaning: Use a soft, dry cloth to clean the amplifier's exterior. Do not use abrasive cleaners, waxes, or solvents.
  • Ventilation: Periodically check that the ventilation openings are clear of dust and debris.
  • Power Cord: Inspect the power cord regularly for any signs of damage. If damaged, replace it with an approved cord of the same type.
