Soundman OKM II Klassik Studio (inc A3) Binaural Mics
The OKM original head-microphone is a ball look Elektret-microphone which comes with an enclosed A3 adapter. This combination can be used o make excellent quality surround recordings.
The OKM original head-microphone is a new and uniquely designed microphone, developed especially for mini recording systems and digital cameras. Its special design allows it to be used for the most diverse applications.
- Excellent frequency responses
- Perfect channel match guaranteeing the best possible stereo image location and outstanding performance
- Measurement report included
- High quality grided cable - made in Germany
- For all studio versions the adapter A3 is shielded against electromagnetic interferences
The A3 Adapter Connection
The OKM condenser microphones need DC powering. This can be sourced either through a microphone jack present on recording devices or through the enclosed A3 Adapter. The A3 will yield the best results when used on LINE inputs. With its automatic level adaptation, high microphone supply voltage and considerably low noise floor, the A3 offers a significantly greater increase in dynamic range when compared to the conventional direct connection to a microphone jack. When recording faint sounds, the OKM can be used on microphone inputs in conjunction with the A3. However, as a result of the smaller surface area of the microphone membrane, system inherent noise is a possibility. As such, care should be taken to avoid preamp clipping that may occur when the recording level control is set too low.
The Adapter A3 is plugged in between the microphones and recording equipment. Please bear in mind that you should remove the microphone plug from the A3 Adapter after use. This is to avoid discharging the battery, since plugging the microphone activates the adapter which uses electricity.
Low Frequency Roll Off
The switch position ” /” is to be chosen when recording speech. This attenuates frequencies below 300Hz. The switch position “-” (linear) is chosen to record music.
The switch position “-20dB” is used when recording high sound pressure levels. For moderate SPLs, especially with the A3 on the LINE input, the switch position “0″ is recommended.
To check the remaining battery capacity, press the test knob, which lights up the green LED. The brightness of the LED offers an indication of the remaining battery life time. If the LED extinguishes, please replace the battery.
When the microphone is placed at some distance from the recording equipment, the microphone cable can be extended, provided that the cable capacity does not exceed 1000 pF. Extending the adapter output cable is not recommended.
