- Vstup střídavého proudu: Connect the provided AC power cable here. Supports 115V/230V AC.
- Vypínač: Toggles the unit's power on or off.
- 50 Ohm Isolated Output (Gentle): Three BNC connectors for 'Gentle' mode clock output.
- 50 Ohm Direct Output (Vivid): Three BNC connectors for 'Vivid' mode clock output.
4.3 Pokyny pro připojení
- Umístění: Place the C16 unit on a stable, level surface, ensuring adequate ventilation. Avoid placing it near heat sources or in direct sunlight.
- Připojení napájení: Connect the AC power cable to the AC power input on the rear panel of the C16, then plug it into a suitable wall outlet. Ensure the power switch is in the 'Off' position before connecting.
- Clock Output Connection: Use high-quality 50 Ohm BNC cables to connect the C16's output ports to the 10MHz clock input ports of your compatible audio devices (e.g., DACs, streamers).
- For 'Vivid' output, connect to the "50 Ohm Direct Output" BNC ports.
- For 'Gentle' output, connect to the "50 Ohm Isolated Output" BNC ports.
5. Návod k obsluze
- Zapnutí: Flip the power switch on the rear panel to the 'On' position.
- Zahřívací období: Upon initial power-on, the dual LEDs on the front panel will flash for approximately fifteen minutes. During this warm-up period, all clock output ports on the rear panel will not provide an output. This allows the OCXO to stabilize for optimal performance.
- Operation After Warm-up: After the 15-minute warm-up, the dual LEDs will remain steadily lit, indicating that all clock outputs are automatically enabled and stable.
- Bypassing Warm-up (Immediate Output): If immediate output is required during the warm-up period, press either the 'Vivid' or 'Gentle' button on the front panel. This will activate the corresponding output mode and bypass the remaining warm-up time.
- Selecting Output Mode: Press the 'Vivid' button to enable the direct output mode, or the 'Gentle' button to enable the isolated output mode. The corresponding LED will illuminate to indicate the active mode. The 'Vivid' mode is generally recommended for most applications.
- Vypnout: To turn off the unit, flip the power switch on the rear panel to the 'Off' position.
6. Údržba
- Čištění: K čištění vnější strany jednotky používejte měkký, suchý hadřík. Nepoužívejte tekuté čisticí prostředky ani abrazivní materiály.
- Větrání: Ensure that the ventilation holes are not obstructed to prevent overheating.
- Skladování: Pokud budete jednotku skladovat delší dobu, odpojte ji od napájení a uložte ji na chladném a suchém místě.
- Žádné díly opravitelné uživatelem: The C16 contains no user-serviceable parts. Do not attempt to open the casing, as this may void your warranty and could result in electric shock.
7. Řešení problémů
| Problém | Možná příčina | Řešení |
|---|---|---|
| Jednotka se nezapne. | Power cable not connected or loose. No power from outlet. | Check power cable connection. Verify outlet has power. Ensure rear power switch is 'On'. |
| No clock output after power on. | Unit is in warm-up period. Output mode not selected. | Wait 15 minutes for warm-up (LEDs flashing). Press 'Vivid' or 'Gentle' button to activate output immediately. Ensure BNC cables are securely connected. |
| LEDs flashing continuously after 15 minutes. | Indicates an internal issue or failure to stabilize. | Vypněte a znovu zapněte zařízení. Pokud problém přetrvává, kontaktujte zákaznickou podporu. |
| Audio quality issues when using C16. | Incorrect BNC cable impedance (should be 50 Ohm). Incompatible receiving device. | Ensure all BNC cables are 50 Ohm. Verify your audio device is compatible with a 10MHz square wave clock input. Try switching between 'Vivid' and 'Gentle' modes. |
