Plan the installation
Match the pickup to the conversation
For a fixed speaking position, point the microphone toward the user. For teller-customer conversations, compare the two-way models and the placement of both speakers.
Check the host and audio path
Match the USB connection and mounting space to your device. If it plays speech through a loudspeaker, include the speaker layout and playback path in the evaluation.
