2. What's in the Box
Please check that all items are present upon unpacking:
- 1 x Sennheiser CL 35 Locking 3.5mm TRS to TRS Coiled Cable
3. Setup
The CL 35 cable is designed for straightforward connection between compatible audio devices.
- Identify Connectors: The cable has two 3.5mm (1/8") TRS connectors. One connector features a locking mechanism, typically identified by a knurled metal ring.
- Connect to Source Device: Insert the non-locking 3.5mm TRS connector into the audio output jack of your source device (e.g., wireless receiver, microphone output).
- Connect to Recording Device: Insert the locking 3.5mm TRS connector into the audio input jack of your recording device (e.g., DSLR camera, mirrorless camera, audio recorder). Ensure the connector is fully seated.
- Secure Locking Connector: If your recording device's input jack supports locking 3.5mm connectors, gently twist the knurled metal ring on the cable's locking connector clockwise until it is secure. This prevents accidental disconnection during use. If your device does not support locking, the connector will still function as a standard 3.5mm TRS plug.
- Test Connection: Before recording, perform a sound check to ensure proper audio signal transmission and a secure connection.
4. Operation
Once connected, the CL 35 cable facilitates the transfer of stereo audio signals between your devices. Its coiled design helps manage cable length and reduces clutter, making it suitable for mobile setups.
- Ensure both connected devices are powered on and configured for the correct audio input/output settings.
- Monitor audio levels on your recording device to prevent clipping or distortion.
- The coiled nature of the cable allows for flexibility in length, extending when needed and retracting for compact storage. Avoid overstretching the coil to maintain its integrity.
5. Maintenance
Proper care will extend the lifespan of your Sennheiser CL 35 cable.
- Cleaning: Use a soft, dry cloth to wipe the cable and connectors. Avoid using harsh chemicals or abrasive materials.
- Storage: When not in use, allow the cable to naturally coil. Do not force it into tight bends or knots. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Always grasp the connector housing when plugging or unplugging the cable, not the cable itself, to prevent damage to the internal wiring.
- Avoid Stress: Do not place heavy objects on the cable or subject it to excessive pulling or tension.
