5. Arahan Persediaan
The SES-XLR-AB can be configured in two primary ways: switching between two inputs to one output, or one input to two outputs.
5.1. Two Inputs to One Output Configuration
- Connect your first audio source (e.g., microphone, mixer output) to the A female XLR input port using a male XLR cable.
- Connect your second audio source to the B female XLR input port using a male XLR cable.
- Connect the single male XLR output port of the SES-XLR-AB to your destination device (e.g., mixer input, audio interface) using a female XLR cable.
- Use the A/B selector switch on the top panel to choose which input source (A or B) is routed to the output.
5.2. One Input to Two Outputs Configuration
- Connect your single audio source (e.g., microphone, mixer output) to the single male XLR input port of the SES-XLR-AB using a female XLR cable.
- Connect your first destination device (e.g., mixer input, audio interface) to the A female XLR output port using a male XLR cable.
- Connect your second destination device to the B female XLR output port using a male XLR cable.
- Use the A/B selector switch on the top panel to choose which output destination (A or B) receives the audio signal from the input.
Note: Ensure all XLR cables are balanced for optimal performance.
6. Arahan Operasi
Operation of the SES-XLR-AB is straightforward:
- Ensure all audio connections are secure before operating.
- To switch between the A and B paths, simply toggle the physical switch located on the top panel of the unit.
- The switch provides a clear tactile indication of the selected path.
- Since the unit is passive, there is no power button or indicator light. The switch functions purely mechanically.
7. Penyelenggaraan
- Pembersihan: Gunakan kain lembut dan kering untuk membersihkan bahagian luar unit. Elakkan pembersih atau pelarut yang kasar.
- Storan: Simpan unit di tempat yang sejuk dan kering jauh dari cahaya matahari langsung dan suhu yang melampau.

- Pengendalian: Avoid dropping the unit or subjecting it to strong impacts, as this may damage internal components or connectors.
8. Penyelesaian masalah
If you encounter issues with your SES-XLR-AB switch, consider the following:
- Tiada Output Audio:
- Ensure all XLR cables are securely connected at both ends.
- Verify that the A/B selector switch is in the correct position for the desired audio path.
- Test cables individually to ensure they are not faulty.
- Confirm that the audio source is active and producing a signal.
- Check the input/output levels on your connected audio equipment.
- Hum atau Bunyi:
- Ensure all cables are balanced XLR cables. Unbalanced cables can introduce noise.
- Check for ground loops in your audio system.
- Ensure cables are not running parallel to power cables, which can induce hum.
