The dark bronze Microtech Gefell UM 930 Dual Multi-Pattern Condenser Microphoneis a multi-pattern large-diaphragm condenser microphone offering ultralow noise and flexible pickup responses for precise capture of vocals and instruments such as strings, percussion, and guitars in recording facilities and radio studios.

It features a dual-capsule design with one cardioid capsule and a second capsule that yields five selectable polar patterns—omnidirectional, cardioid, wide cardioid, supercardioid, and figure-8, making it equally well suited for use as a main mic or as a part of stereo and mid-side configurations. In addition to conventional switched patterns, two different directional patterns can be selected at the same time. The transformerless circuitry incorporates a transistor amplifier and produces only 7 dBA of self-noise.

The UM 930 Twin's high sensitivity and 48V phantom powering method ensure reliable performance with a variety of mic preamps. An EA 92 shockmount is supplied to help isolate the mic from vibrations and handling noise along with a hard case to house the microphone and the mount.

• The UM 930 Twin is equipped with one fixed cardioid polar pattern and five additional user-selectable polar pattern options. The 5-pin XLR connector enables the separate capsule directivity patterns to be used simultaneously.
• This makes it possible for the recording engineer to compare the directional properties against the reference cardioid during live recording as well as in postproduction.
• Continuous control of the variable polar pattern from the mixing console or PC is possible using separate signal outputs.

• For vocals, speaker positions, radio plays, and as a support microphone for recording guitars, keyboard, percussion, wind, and string instruments

Q: 1. Will it work with a Macbook Pro through Thunderbolt 3?

A: It will work through a Thunderbolt 3/ USB-C connection on a Macbook Pro. But you will need this Apple USB-C to A adapter to connect it. https://www.bhphotovideo.com/c/product/1128928-REG/apple_mj1m2am_a_usb_c_to_usb_adapter.html.

Q: 2. The "Key Features" at the top say Max SPL = 140db, but the Specs say it is 130db. Which is correct?

A: The published specification is correct for the Senal SCM-660 Large-Diaphragm Multi-Pattern Condenser Microphone (BH # SESCM660). It is 130 dB, but will be 140 dB with the -10 dB pad engaged. See the page 10 of the user guide here: https://bhpho.to/3WFcOhz.

Q: 3. how do i swap tube in CV 12. is there a quick way without ant unscrewing?

A: You are not able to remove the tube of the CV-12 without some disassembly. Unfortunately we are not able to provide detailed instructions.

Q: 4. This is the second time, the mic is not working properly, I got really low volume signal. The first time it was fixed by itself after a few days but not this time, how can I use the warranty? This microphone was a birthday present and I don't have the invoice

A: Aventone microphones carry a five-year warranty when purchased new. Tel: (845) 642.3697 or info@avantonepro.com However, I would encourage you to give us a call as we may be able to help trouble shoot the mic, and determine whether or not it truly defective. 800-606-6969

Q: 5. What software do I need to capture the sound files?

A: You can use that microphone with any standard Digital Audio Workstation (DAW). Here's an option for Presonus Studio One 4 Artist: https://www.bhphotovideo.com/c/product/1405910-REG/presonus_s14_art_studio_one_4_artist.html.

Q: 6. Do I need +48V phantom power to operate?

A: K2 lists use with a power supply. Microphone comes with a power supply. The K2 can be used with mains supply voltages of between either 110-120V 50/60Hz or 220-240V 50/60Hz.

Q: 7. Does this microphone connect to the computer with a 3.5mm jack in addition to the USB cable?

A: No. Only USB.

Q: 8. Can I use this microphone with my Iphone 10 with the lightining to usb converter for zoom calls ?

A: No. According to Apple, external microphones will not work with iPhones for video calls or conferencing apps like Zoom or FaceTime and only the built-in mic will work for those types of apps. External mics can be used with the iPhone for recording audio with video and for regular audio calls. Additionally, the UC4-B was designed for use with a computer and it will work for Zoom video calls with a computer. The mic would probably work for recording audio on the iPhone with the Lightning to USB adapter, though it would drain the phone's battery very quickly because it draws power via USB and more power than the iPhone can supply. iPhones were not designed for use with this type of mic.

Q: 9. is it USB C type ?if not which mic is coming with USB C thanks

A: Unfortunately, this does not include a USB-C output cable. Although it is mostly mics designed for mobile that include a USB-C cable, you could use a separate cable like this with the mic, and it will work with a USB-C connection to a computer: https://www.bhphotovideo.com/c/product/1141593-REG/belkin_f2cu033bt06_blk_usb_2_0_c_to.html
