സജ്ജമാക്കുക
The MC103-Pro offers two primary connection modes: 3-IN-1-OUT and 1-IN-3-OUT. Ensure all audio equipment is powered off before making connections.
3-IN-1-OUT Configuration
In this mode, you can connect up to three stereo XLR audio sources (e.g., DVD player, CD player, Decoder) to the MC103-Pro, and output the selected source to a single stereo XLR destination (e.g., an ampജീവപര്യന്തം).
- Connect your first stereo XLR audio source to the "X" input ports (Left and Right) on the rear panel of the MC103-Pro.
- Connect your second stereo XLR audio source to the "Y" input ports (Left and Right).
- Connect your third stereo XLR audio source to the "Z" input ports (Left and Right).
- Connect your stereo XLR amplifier or other audio destination to the "I/O" output ports (Left and Right).

1-IN-3-OUT Configuration
In this mode, you can connect a single stereo XLR audio source (e.g., a Decoder) to the MC103-Pro, and output that source to up to three different stereo XLR destinations (e.g., multiple ampജീവപര്യന്തം).
- Connect your stereo XLR audio source to the "I/O" input ports (Left and Right) on the rear panel of the MC103-Pro.
- Connect your first stereo XLR amplifier or other audio destination to the "X" output ports (Left and Right).
- Connect your second stereo XLR amplifier or other audio destination to the "Y" output ports (Left and Right).
- Connect your third stereo XLR amplifier or other audio destination to the "Z" output ports (Left and Right).

The MC103-Pro is a passive device and does not require external power. Ensure all XLR cables are securely connected to prevent signal loss or noise.
പ്രവർത്തന നിർദ്ദേശങ്ങൾ
Once the MC103-Pro is connected according to your desired configuration, operation is straightforward:
- പവർ ഓൺ ഉപകരണങ്ങൾ: Turn on your audio sources and destination devices (e.g., ampജീവപര്യന്തം).
- ഇൻപുട്ട്/ഔട്ട്പുട്ട് തിരഞ്ഞെടുക്കുക: Use the large rotary knob on the front panel of the MC103-Pro to select the desired input (X, Y, or Z in 3-IN-1-OUT mode) or output (X, Y, or Z in 1-IN-3-OUT mode). The knob will click into place for each selection.
- ഓഡിയോ പ്ലേബാക്ക്: Begin playing audio from your selected source. The audio will be routed through the MC103-Pro to your chosen destination.
Since the MC103-Pro is a passive switcher, it does not add any coloration or degradation to the audio signal. The selection is purely mechanical, ensuring a clean signal path.
