Setup Instructions
- Unpacking: Carefully remove all components from the locking flight case. Inspect each item for any signs of damage.
- Mounting the Microphones:
- Attach each TF51 microphone to an M703 Elastic Shock Mount. Ensure the microphone is securely fastened within the mount to prevent accidental drops and isolate it from vibrations.
- Mount the shock mounts onto appropriate microphone stands (not included).
- Connecting Cables:
- Connect one end of each M803 Tube Microphone Cable (7-pin) to the corresponding TF51 microphone. Align the pins carefully and twist the connector to lock it in place.
- Connect the other end of each M803 cable to the designated inputs on the M901S Dual Power Supply.
- Power Supply Connection:
- Connect the M901S Dual Power Supply to a standard AC power outlet using the provided power cord.
- Connect the XLR output cables (not included) from the M901S Dual Power Supply to your audio interface or mixing console inputs.
- Power On: Once all connections are secure, switch on the M901S Dual Power Supply. Allow a few minutes for the microphone tubes to warm up before use.
Operating the Microphones
The TF51 microphones offer multiple polar patterns, allowing for versatility in various recording scenarios. The polar pattern selection switch is located on the M901S Dual Power Supply.
- Cardioid (Unidirectional): This pattern picks up sound primarily from the front, rejecting sound from the sides and rear. Ideal for vocals, individual instruments, and situations where isolation from other sound sources is desired.
- Omnidirectional: This pattern picks up sound equally from all directions. Suitable for capturing room ambiance, group vocals, or when a natural, open sound is preferred.
- Figure-8 (Bidirectional): This pattern picks up sound equally from the front and rear, while rejecting sound from the sides. Useful for recording two vocalists facing each other, or for certain stereo miking techniques.
Stereo Recording: As a stereo set, the TF51 microphones are ideal for techniques such as X-Y, ORTF, or A-B stereo miking to capture a wide and immersive soundstage for acoustic instruments, drum overheads, or room recordings. Experiment with microphone placement and polar patterns to achieve the desired stereo image.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the microphones and power supply. Avoid using liquid cleaners or solvents, as these can damage the finish or internal components. Do not attempt to clean the microphone grille with liquids.
- Storage: When not in use, store the microphones in their provided sleeves and within the locking flight case. This protects them from dust, moisture, and physical damage. Store in a cool, dry environment.
- Tube Life: The vacuum tubes inside the microphones have a finite lifespan. While designed for durability, excessive heat or physical shock can shorten their life. If you notice a degradation in sound quality over time, consult TELEFUNKEN support for tube replacement options.
