built-in stand
CM­15 has a built-in table stand that can be used to rest and angle the microphone on a surface. for the best possible recording quality, make sure to avoid any unwanted surface vibrations when recording this way.

tripod adapter
your CM­15 also comes with a standard ¼” and ” adapter, making it universally compatible with standard microphone stands and tripods. it fits perfectly with the tripod mini accessory (sold separately). mount the adapter by first loosening the thumbscrew. place it on the center, bottom side of the mic, and tighten until properly mounted. fix the adapter on the tripod by simply screwing it on clockwise.

outputs
CM­15 field mic features three audio outputs that can be used individually or in any simultaneous combination. the three outputs are located on the bottom of the unit: the mini xlr, 3.5 mm mini jack and usb-c. this means there are two analog outputs, each with its own advantage for use. the usb-c port can be used as a digital audio interface, as well as for firmware updates and for charging the internal battery.

connections

mini xlr
the compact size mini xlr output gives you the highest quality recordings and is intended to be used with your recording console, preamp or audio interface. use the included mini xlr to xlr cable, and apply 48 volt phantom power. the power consumption is around 3 mA. in phantom-power operation the status led is green.

mini jack
the mini jack output is meant to be used in portable battery powered scenarios, such as with TX­6, OB­4 or a camera mic input. it is a line level output and it features a dual mono signal, meaning the signal is identical for both tip and ring. use a stereo cable for stereo inputs, or a stereo to dual mono splitter for mono inputs. note: do not apply phantom power to the mini jack.

usb-c
CM­15 is a usb class compliant audio device. when connecting it to a usb host device, such as a laptop or OP­1 field, it will show up as a 1-input audio interface, as long as the unit is turned on. when connected while turned off, the device is only charging the battery and it won’t show up as an interface.

the available audio rates are: · 44.1 kHz · 48 kHz · 88.2 kHz · 96 kHz when in usb mode, an additional ±12 dB digital gain is applicable from the usb interface settings in your computer.

CM­15 is designed to be easy to use. use the tripod adapter or the built in stand to set it up, connect any cable needed for your application and you are ready to record.

the only setting on the microphone itself is the pad / gain switch. adjust it based on the sound source. move the switch left to pad -18 dB, and right to gain +18 dB. this is analog gain that applies to all the outputs, without SNR degradation. additional ±12 dB are available digitally in usb mode.

the pad / gain switch has three settings: -18 dB, 0 dB and +18 dB.

move the switch to the far left position to pad -18 dB.

+18 dB
move the switch to the far right position to apply +18 dB gain.

scenarios

as with all teenage engineering products, CM­15 has been developed with portability and compatibility in mind. while it is best used in a controlled studio setting, the following pages illustrate a variety of ways in which CM­15 can be put to use. make sure to adjust the pad / gain switch accordingly based on the sound source.

CM­15 features an acoustically transparent fine mesh to protect the capsule. however, do not abuse the capsule by blowing directly on the front or back of the microphone. slightly angling the mic away from your mouth, or a high pressure sound source, will give a natural pop filter effect. an external pop filter is recommended for voice recordings, such as podcasts and singing. a windscreen is recommended for outdoor use.

mounting options

to get the most out of your CM­15 mic, we have developed a stand: tripod mini. tripod mini measures 184 mm in height, unfolded, with the adapter mounted, and 146 mm when standing. the mic is easily mounted with the included adapter. the adapter helps you tilt the unit in the angle you prefer, 90° frontwards and 110° backwards. the angle makes it possible for the mic to be mounted on a boom arm or to tilt it to better record overheads.

adjust the angle by rotating the center screw on the tripod. tighten or loosen the mount with the thumb screw on the adapter.
