  • Page 2 Thank you for choosing Senal. The Senal SCI-3212 is a rugged small-diaphragm condenser microphone capable of delivering professional-quality audio for a variety of recording applications in the field or in the studio� Its unique design features three interchangeable capsules that allow this microphone to change polar patterns quickly and easily� The omnidirectional, cardioid, and supercardioid capsules provide adaptability for a wide range of recording scenarios� The excellent transient response and high sensitivity assure detailed and accurate sound when recording instruments or dialog� High SPL handling capability enables close mic placement to cymbals, pianos, guitars, and other acoustic instruments, as well as recording in high- noise environments� As a matched pair, the SCI-3212’s versatility provides the option of selecting between several stereo miking techniques for a wide and true stereo sound� An included shock mount allows for easy boompole mounting when recording dialog indoors or in the studio� The included foam windscreen minimizes wind noise when shooting outdoors� Introduction ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪...

  • Page 4 Precautions The Interchangeable Microphone Capsules ▪ Please read and follow The SCI-3212 comes with the cardioid capsule these instructions and keep attached� To change the capsule: this manual in a safe place� • Remove the capsule from the microphone by ▪ Keep this product away turning it counterclockwise� from water and all • Attach the new capsule by screwing it flammable gases or liquids� clockwise onto the microphone� ▪ Do not attempt to disassemble or repair this product� ▪ Make sure that this product is intact and that there are no missing parts� ▪ All images are for illustrative purposes only� Precautions / The Interchangeable Microphone Capsules ▪ ▪...
  • Page 5 Omnidirectional capsule Due to the high sensitivity of the SCI-3212, the omnidirectional capsule is suitable for capturing ambient sounds of the environment and for nature recording� It’s also a good choice when recording live sound or music� Consider the omnidirectional capsule when close-miking guitars or voices in the studio or in quiet spaces without background noise� As a matched pair, the omnidirectional capsule is ideal for A/B stereo recording� See A/B (Spaced Pair) technique on page 6� Cardioid capsule The cardioid capsule offers a wide variety of uses in the field and in the studio� It’s ideal for capturing acoustic instruments in live and studio settings, and it’s very effective as a drum mic or as a drum overhead� When recording speech or dialog in the studio or on location, the cardioid polar pattern is less susceptible to picking up reflections than shotgun microphones� This makes it an excellent option for boompole use� As a stereo pair, the cardioid capsules are excellent for X/Y and ORTF stereo recording� See X/Y (Coincident Pair) technique on page 7 and ORTF (Near Coincident) technique on page 8� Supercardioid capsule The supercardioid capsule focuses on the sound directly in front of it while rejecting off-axis sound� This is advantageous when recording interviews or dialog in noisy environments� It is also well suited for loud stage environments� The Interchangeable Microphone Capsules ▪ ▪ ▪...
  • Page 6 Stereo Microphone Techniques Your matched pair of Senal SCI-3212 microphones is ideal for capturing stereo sound� Microphone placement is crucial in successful stereo recordings� The following are a few common microphone techniques for creating stereo sound images� As in all miking scenarios, experimenting with the distance from your sound source and the distance between the microphones will ultimately result in the best stereo recordings� A/B (Spaced Pair) technique Use the omnidirectional capsules� • Place the microphones parallel to each other and point both microphones toward the sound source� • There’s no hard and fast rule for achieving the best results using this technique� Experiment by adjusting the distance of the microphones from the sound source, and the distance of the mics from each other� • Send the mono signal from each microphone to its own track� Note: Due to the timing offset of the sound reaching each microphone, you may experience phase cancellation if mixing the stereo signal down to a mono track� Stereo Microphone Techniques ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪...
  • Page 7 X/Y (Coincident Pair) technique Use the cardioid capsules� Since the capsules are placed close together, the stereo image won’t be as wide as the A/B or M/S techniques� • Place the two microphones at an angle between 90° and 135° so that the two capsules are very close to each other but not touching� • The ideal configuration is to have the microphones placed vertically so that one capsule is directly above the other� However, placing the microphones side by side will also deliver satisfactory results� • The wider the angle is, the wider the stereo image will be� 90°–135° • Send the mono signal from each microphone to its own track� Note: If you are mixing the two tracks down to a mono track, you will not encounter the potential phase cancellation issues that can occur in the other mic techniques� Stereo Microphone Techniques ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪...
  • Page 8 ORTF (Near Coincident) technique Use the cardioid capsules� This technique is good for recording dialog or sound in stereo without picking up a lot of the ambient room noise� • Spread the microphones outward at an angle of 110° while making sure that the capsules are about 6�5″ (17 cm) apart� • Send the mono signal from each microphone to its own track� Note: Due to the timing offset of the sound reaching each 110° microphone, you may experience phase cancellation if mixing the stereo signal down to a mono track� Stereo Microphone Techniques ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪...
  • Page 9 M/S (Mid/Side) technique Use either the cardioid or omnidirectional capsules� This technique requires one SCI- 3212 microphone and a figure-8 (bidirectional) large-diaphragm condenser microphone like the Senal SCM-660� This technique is excellent for capturing the ambience surrounding your sound source and often offers the greatest stereo width� • Point the SCI-3212 directly at the sound source (mid)� • Place the figure-8 microphone just below the capsule Sound of the SCI-3212 and at a 90° angle (side)� Source 90° • Send the stereo signal from the figure-8 microphone to a stereo track, and the mono signal from the cardioid microphone to its own mono track� • The cardioid microphone (mid) will record the sound source directly in front of it while rejecting the off-axis sound� The figure-8 microphone (side) will record the off-axis sound� Note: Mixing these signals can be tricky� Duplicate the side channel and reverse the polarity� Then combine both side tracks onto one stereo track� Mix in the mid channel with the stereo track� The louder the stereo side track is, the greater the stereo width will be� Stereo Microphone Techniques ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪...
