Advanced microphone settings After selecting the preset mode, the app allows you to fine-tune the sound sources with equalizer, limiter and compressor settings. These settings are retained in the microphone when other audio and video recording applications are used. Limiter: Use the limiter to control volume peaks by setting an input threshold. Compressor: Use the compressor when the sound source is very dynamic. The compressor narrows the dynamic range; weak signals are amplified and loud signals are attenuated. Light and heavy compression options are available. Equalizer: Use the equalizer to boost or cut frequency bands and to improve the purity of the sound. The user-specific changes made to the equalization are reflected in the equalizer symbol. Record Go to the Record screen for instant control of recording. 3/16

6 Tips for recording Turn off notifications When a MOTIV device is connected to the Android device, a message appears asking the user to activate airplane mode and do not disturb. Set these models to avoid interference from phone calls, messages, and notifications that add noise to recordings. With Android devices, it is not possible to make phone calls and record USB audio at the same time. When a phone call is received, recording stops. Use dark theme Select the option Dark theme for dark display to switch the app from light gray to dark gray. The darker display is ideal for inconspicuous shots in low light. The settings for the dark design are selected via Menu> Settings> Appearance> Dark. Recording the Complete Performance To ensure that the entire sound source is captured, recording should be started before the performance begins. The recording can be edited afterwards to cut out the silent part. Note: If the microphone is accidentally disconnected during recording, the MOTIV app will automatically stop recording. The Save File dialog box appears and prompts you to name and save the audio files. Keeping the recording If the microphone is accidentally disconnected while recording, the app will automatically stop recording. The Save File dialog box appears and prompts you to name and save the audio recording. If a recording is made at an event and the file exceeds the maximum file size of 2 GB, a second recording is made. This limitation is used to optimize the performance of the app. Note: Low storage space or low battery level will affect the available recording time. Keep screen active during recording The Keep screen active during recording option ensures that the display remains switched on during longer recording sessions and that the gain levels can be continuously monitored. 6/16

Troubleshooting Problem The MOTIV device is plugged in, but the device's LED indicator does not light up and the device is not recognized by the app. The microphone is plugged in, but the level meter shows no signal. The microphone was plugged back in, but the level meter still shows no signal. Audio sounds bad or far away. Audio signal is distorted Remedy Make sure that the cables are connected in the correct order: MOTIV device to Micro-B USB cable to On-The-Go (OTG) cable to Android device. Unplug the microphone and plug it in again if the name of the microphone does not appear in the status bar. If the lights on the MOTIV device still do not light up, the mobile phone may not be supplying sufficient power. Check the device settings to activate the USB power supply. Make sure the connection cable is an On-The-Go (OTG) cable. To ensure that the audio signal is being recorded by the microphone and not by a built-in microphone, unplug the microphone and plug it in again. The Shure MOTIV microphone will appear in the top left corner of the screen when connected. Using the audio level display, check whether the volume peaks are in the optimal range (shaded gray). When the level reaches the red peak display on the input level meter, decrease the gain.
