Delivered in a suitcase with mic clips and a stereo rail for a variety of stereo recording options, this matched pair of dark bronze Microtech Gefell M 310 Small-Diaphragm Supercardioid Condenser Microphones with Basic Accessories features two microphones designed for accurate reproduction of solo instruments and vocals in live stage applications and home, project, and commercial recording studios.

The unique mic capsule features a 16mm gold-sputtered Mylar diaphragm and is constructed from ceramic rather than metal to ensure consistent performance at a variety of temperatures. The capsule is protected by a triple-layer wire-mesh grille at the front and a dual-layer mesh for the rear-entry ports. The pressure-gradient design and supercardioid polar pattern focus audio capture tightly on the source, helping to reject unwanted off-axis sounds for less bleed from other instruments or sound-reinforcement equipment. Transformerless circuitry yields low noise and contributes to a high dynamic range of 131 dB. This matched pair allows for a wide variety of stereo miking configurations.

The 20 Hz to 20 kHz frequency response features a gentle treble boost to increase clarity and presence. An XLR 3-pin output with gold-plated contacts ensures standardized connectivity and 48 VDC phantom powering provides battery-free operation.

• Ideal for stereo miking instruments and ensembles
• Small-diaphragm capsule allows a compact body for easy placement in tight spaces
• Supercardioid polar pattern delivers focused frontal directivity and enhanced off-axis rejection, making it well suited for spaces that lack acoustic treatment
• Transformerless circuitry contributes to low noise and high dynamic range
• 20 Hz to 20 kHz frequency response with a smooth treble boost for presence
• High maximum SPL of 147 dB
• 48 VDC phantom powered—no batteries required
• XLR 3-pin output allows easy connection to most mic preamps, audio interfaces, and recording consoles
• Includes one 25mm stereo bracket for easy positioning in stereo configurations
• Includes two MH 93.1 mic holders
• Includes a suitcase for safe storage and transport

• To ensure the highest quality performance, phantom power goes through a DC/DC converter to raise the voltage to 60V; this high polarizing voltage makes for the mic's impressive SPL handling and keeps self-noise to a minimum.
• In addition, the polarizing voltage is delivered to the capsule via an optical coupler, which decouples the supply, reducing ripple and virtually eliminates any phantom power supply noise and/or spurious interference.
• The electronics involve some clever optically isolated powering technology, in which a high-intensity LED, driven directly from the phantom supply, illuminates a photocell, which drives a DC/DC converter. This innovative approach neatly isolates the capsule bias and impedance converter power rails from the phantom supply, which helps in achieving the mic's very low noise floor. This effectively performs the task of the transformer without the ringing or bandwidth limitation that is usually associated.
• By providing pure DC to the capsule, you get both an improved performance and a lower self noise, most notably in the broadband spectrum.
• RFI protection is high, making susceptibility to radio interference extremely low.

Q: 3. Will these be better for indoor dialogue than an rode ntg 2 ?

A: Only in one regard. The NTG2 is a shotgun microphone, which means it is directional because it has an interference tube. Surfaces nearby (such as a ceiling several inches away) that reflect sound can defeat the interference tube, causing more background noise than expected to be recorded. For this reason, shotgun microphones are discouraged for indoor dialog. The C02 does not have an interference tube, so it does not have this problem. It is very directional, and it is a good fit for using on a boom for indoor dialog, even near sound-reflecting surfaces.That said, both the C02 and the NTG2 are a little weak in their ability to pick up the lowest and highest sound frequencies, but the NTG2 seems to be a little better in this regard.

Q: 4. Will the Pentax CS-310 cable switch work on the Pentax KP?

A: Yes the Pentax CS-310 Cable Switch is compatible with the Pentax KP.

Q: 5. Will Pentax CS-310 cable switch work on Pentax KF?

A: Yes, the Pentax CS-310 Cable Switch will work with the Pentax KF DSLR Camera (Black).

Q: 6. What size thread are the included shock mounts?

A: The shock mounts that are included with the Samson C02 Pencil Condenser Microphones have a 5/8"-27 thread.

Q: 7. Is it possible to change the capsules to put some with other polar patterns?

A: I was a little surprised to find that the C02 does indeed have a modular capsule design, and it would suggest this intent. However, Samson does not appear to make or sell any other capsules that would fit (at this time). Perhaps they will in the future.

Q: 8. Do these have balanced matched triodes?

A: Yes they do. They are a matched pair of Telefunken E88CC-TK/6922 Black Diamond Series Vacuum Tubes.

Q: 9. Will this work with an earlier K3?

A: No, that will not work on a Pentax K3 version one. The version one uses a 2.5mm port not 3.5 like the Pentax CS-310. These are some that will work with the K3 version one, https://bhpho.to/3Cn8A3n https://bhpho.to/2U1abdI https://bhpho.to/3yyH4xw

Q: 10. Will this work on a Pentax K70?

A: Yes, the Pentax CS-310 Cable Switch is compatible for use with the Pentax K-70 DSLR camera.
