3.1 ඇසිරීම

ප්රවේශමෙන් ඉවත් කරන්න amplifier from its packaging. Verify that all components listed in the 'What's in the Box' section are present. This includes the MX1680 GEN2 amplifier and the Quick Start Guide.

3.2 ස්ථානගත කිරීම

The MX1680 GEN2 is designed for rack mounting (2U height) or placement on a flat, stable surface. Ensure adequate ventilation around the unit to prevent overheating. Avoid placing it near other heat-generating equipment.

3.3 සම්බන්ධතා

Refer to the rear panel diagram for all input and output connections.

  • කථික නිමැවුම්: Connect your speakers to the corresponding zone terminals. Ensure correct polarity (+ to + and - to -). The amplifier supports both 4-ohm and 8-ohm speakers. For bridged mode operation, refer to section 4.3.
  • රේඛා ආදාන (RCA): Each zone has a dedicated stereo RCA Line In. Connect your audio sources (e.g., pre-amplifier, media player) to these inputs.
  • Bus Inputs (RCA): ද amplifier features two stereo Bus Inputs (Bus In 1, Bus In 2). These allow a single audio source to be distributed to multiple zones.
  • රේඛා ප්‍රතිදානය (RCA): Each zone also has a stereo RCA Line Out, allowing the audio signal from that zone to be passed to another amplifier හෝ ශ්රව්ය උපකරණය.
  • ක්‍රියාරම්භක ඇතුල්/පිටත: The 12V Trigger In allows the amplifier to be turned on/off by an external device. The 12V Trigger Out can be used to control other devices.
  • AC බල ආදානය: Connect the supplied power cord to the AC IN receptacle and then to a suitable wall outlet.

4.3 Input Selection and Volume Adjustment

On the rear panel, each zone features switches for input selection and rotary controls for volume adjustment:

  • ආදාන තේරීම: A slide switch allows you to select the audio input for each zone: පේළිය (dedicated input for that zone), Bus In 1, හෝ Bus In 2.
  • ශබ්ද පාලනය: Separate rotary controls for Left and Right channels (Vol. Left, Vol. Right) allow for precise volume balancing within each zone.
  • Stereo/Bridge Switch: A switch allows you to configure the zone for stereo operation or bridged mono operation. In bridged mode, two amplifier channels combine to deliver higher power to a single speaker. Ensure the speaker impedance is appropriate for bridged mode (typically 8 ohms minimum).

4.4 Audio Sensing

ද amplifier incorporates an audio sense feature that automatically activates a zone when an input signal is detected and turns it off after a period of no signal. This helps conserve power and prolong the unit's lifespan.
