5.1 Connecting an Audio Input Device
For better sound pickup quality, you can connect a VPM220 microphone array (VPM220 for
short) or VPM220W wireless microphone array (VPM220W for short) to your TE30.
Before connecting any audio input device to your TE30, familiarize yourself with each audio
input port so that you can quickly and properly make the connections. Table 5-1 provides
information about the audio input ports.

5.1.1 Connecting a VPM220
The VP220 provides 360° sound pickup and an optimal pickup range of six meters. Use the 10
m proprietary cable provided with the VPM220 to connect the HD-AI connector of the TE30
integrated cable to the VPM220 IN port. Once the connection is set up, your TE30 automatically
uses the VPM220 instead of its built-in microphone to pick up sound.
VPM220 status indicators quickly provide information about the VPM220 working status. Table
5-2 describes the status indicators.
