MMA-A is a digital audio interface designed to connect up to two DPA microphones, with MicroDot termination, to an iOS device, PC, or Mac – making it a popular choice for interview, ambience recording or ENG use.
Connectivity to an iOS device is via the included 100cm microUSB-B to Lightning cable, with compatibility for iPhone 5 or newer; iPad Air, iPad mini 4, iPod touch 6th generation; using iOS version 10 or later. The DPA app, which can be downloaded from the Apple Store, enables the user to store up to four user presets including individual input channel gain settings along with low-cut filters, stereo/mono/dual switching. A monitor button allows the user to send the audio to the headphones if connected. The current consumption of less than 100mA equates to approximately 6-7 hours of audio capture on a new iPhone 6 or 7.
Connectivity to PC or Mac is via the included 30cm microUSB-B to USB-A cable.
