5. Operating Instructions

5.1 Initial Audio Setup (Computer/Mobile Device)

• Windows: Go to Sound Settings > Playback and Recording tabs. Select "TOPPING E2X2 OTG" as the default device.
• macOS: Go to System Preferences > Sound > Input and Output tabs. Select "TOPPING E2X2 OTG".
• iOS/Android: The device should automatically recognize the E2X2 OTG as an external audio device. Ensure your recording application is configured to use the external interface.

5.2 Recording with the CL101 Microphone

1. Ensure the CL101 microphone is connected to an input on the E2X2 OTG.
2. Press the 48V button corresponding to the input connected to the CL101. The LED will illuminate, providing phantom power to the microphone.
3. If recording an instrument directly (e.g., guitar), connect it to an input and press the INST button for that input. Do not activate 48V phantom power for dynamic microphones or instruments that do not require it.
4. Open your Digital Audio Workstation (DAW) or recording software. Select "TOPPING E2X2 OTG" as your audio input and output device.
5. Create a new audio track and select the appropriate input (e.g., Input 1 for IN1 L).
6. Speak or sing into the CL101 microphone. Slowly turn up the corresponding GAIN knob until the input level meters show a healthy signal, typically peaking around -6dB to -3dB. Avoid the CLIP indicator lighting up consistently.
7. Adjust the MONITOR knob to blend between your direct input signal (for zero-latency monitoring) and the playback from your computer. Turn it towards "IN" to hear more of your live input, and towards "OUT" to hear more of your computer's playback.
8. Adjust your headphone volume using the dedicated headphone volume knob.
9. Begin recording.

5.3 Playback

Once the E2X2 OTG is selected as your default audio output device, all audio from your computer or mobile device will play through the interface's main outputs and headphone output. Adjust the MONITOR knob to control the blend of playback audio with live input.

6. Maintenance and Care

• Cleaning: Use a soft, dry cloth to clean the surfaces of the audio interface and microphone. Do not use liquid cleaners or abrasive materials.
• Storage: When not in use, store the microphone and interface in a dry, dust-free environment. The CL101 microphone comes with a protective carrying case for safe storage and transport.
• Handling: Avoid dropping or subjecting the devices to strong impacts. The CL101 microphone, especially its capsule, is delicate.
• Environmental Conditions: Do not expose the products to extreme temperatures, humidity, or direct sunlight.
• Cable Management: Ensure cables are not kinked or strained. Disconnect cables by pulling the plug, not the cable itself.
