Connecting One to External Devices
If you're connecting to an input-only jack, such as the input to a wireless transmitter or a microphone input jack, simply use one of the provided male-male 3.5mm plug cables. Plug one plug into One and the other into the input jack of your device. If you wish to monitor the output with headphones while recording, use the Thinklink Connection System or an audio splitter.
If you're connecting to a device with a "headset" jack (i.e., it provides both microphone input AND headphone output in one 3.5mm jack), use Thinklink, which provides switching to facilitate changing the direction of signals - from stethoscope to device for recording and from device to headphones for playback.
Use the Thinklink Connection System provided with your Thinklabs One and carefully follow the Thinklink Instructions provided.
