MMA-A App DPA Microphones DESCRIPTION The MMA-A App allows you to optimize the audio you capture with the DPA Microphones MMA-A Digital Audio Interface and use its features with your favorite recording apps. While the MMA-A can be used right out of the box to capture crystal-clear audio, to take full advantage of it we suggest downloading and using the MMA-A App. The App gives you more control over the sound you are recording / transmitting, so you are sure you end up with the end results you are looking for. The MMA-A App allows you to control the following settings: GAIN Use the GAIN slider to adjust input levels. Slide to the right to increase amplification, to the left to decrease. Make sure to keep an eye on the level meters when you are adjusting gain. The meters should stay in the green and yellow areas. FILTER The FILTER button (low cut) cuts out unwanted, low-end frequencies (rumble) that can decrease the intelligibility of your recorded audio. In most cases we suggest using the FILTER button and if, for example, you are recording outside near a road with traffic, this setting is essential. MONITOR Use the MON button to send audio to your headphones so you can hear what you are recording. Please note that a headphone must be connected to the iOS device, otherwise the button will not activate and you’ll be prompted to connect a headset. If the headset includes a microphone it must be connected prior to connecting the MMA-A via the Lightning connector. This is due to the iOS ‘last entry active’ nature of operation. (We recommend using a wireless headset when using an iPhone 7 or newer model without the minijack headphone output) LOCK Use the LOCK button to block 3rd party apps from controlling gain. Gain settings can be controlled and saved on the MMA-A for use in your favorite recording / broadcasting apps. The lock button also controls the setting of the low cut filter. Saved locked settings are automatically activated the next time you connect to the MMA-A. PRESETS Presets store your preferred settings for specific microphone(s) and make your set up easier. After choosing your settings, create the preset by pushing the numbered preset button of your choice for three seconds. The next time you plug in the same mics, push your preset button and you are ready to go – no adjustments necessary. OTHER FEATURES These features ensure that your MMA-A experience is tailored to your needs: MONO If only one microphone is connected to either input I or II, MONO is chosen automatically. The mic input will be routed to both left and right output. Only one GAIN slider and FILTER button will be available in this mode. STEREO Use STEREO when you need to capture sound sources in stereo. Both microphones are controlled with one GAIN slider. Example: Ambiance sounds can be recorded in stereo using two mics that have the same sensitivity. DUAL Use DUAL when the gain must be set individually for input I and II (for example, with two different microphone types or in situations where two people with different voice levels are to be recorded). The FILTER buttons are also individual in this situation. SUM Use SUM to make a mix of the two input channels. When two microphones are connected, the MONO button changes to SUM. This means that the two inputs will be sent to both output channels. Individual gain can be set for each input. ABOUT the MMA-A The MMA-A Digital Audio Interface is a high-quality dual-channel microphone preamplifier and A/D converter. It allows you to capture crystal-clear audio via your favorite recording / broadcasting apps. The MMA-A can be used with all DPA microphones with a MicroDot adapter. ## Key features - Adjustable gain control - Low-cut filter for rumble reduction - Headphone monitoring - Lock third-party app control - Save custom presets - Mono, stereo, and dual input modes ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/dpa-mma-a/id1182987675/reviews.md ### 4/5 — Quite good *2021-05-05* Sound works great .. I have to switch out of app to use another recording app .. would be nice to record directly. Sound quality excellent ### 5/5 — Love This Product *2019-11-30* I use my 4061 series microphones for location and event recording and found the MMA-A to be the best option out there as far as low profile and high quality sound. This little device is truly a knock out and the app and integrations into ferrite and voice recorder pro (among others) is outstanding.
