Complaint Summary: E&G Series Audio Interfaces
After-sales troubleshooting documents：https://faq.maono.com/docs/audio_interface Q A Solution
Startup issue Q1: Why can't my sound card be powered on or it automatically shuts down after being powered on? 1. Please check if the sound card has power. You can check the battery level by the number of power indicator lights on the sound card panel. If only one power indicator light is on, the battery is low. Please connect the power cord and charge for 3-5 hours before trying to turn it on.

2. Please note that you need to press and hold the power button for more than 3 seconds when turning on the device.		 1. Check if there is power.

2. Press and hold the power button for more than three seconds to turn it on.
Microphone input issue Q2: Why is there no sound when my microphone is connected to the sound card? 1. Please check that the microphone is correctly connected to the sound card's microphone jack (MIC1 or MIC2).

2. Check that the "MIC" monitoring/volume knob (or fader) on the sound card's front panel is turned on. Rotate it clockwise or push it upwards to increase the microphone volume.

3. If using an XLR microphone (AME2/E2 GEN2 only), ensure that the "48V phantom power" button on the front panel is turned on. Also check the "Gain" knob on the back of the sound card and adjust it to an appropriate position (e.g., 3 o'clock).

4. Sound cards typically do not support USB microphones. The AM200 only supports 3.5mm microphones (XLR is not supported); the AME2 and E2 GEN2 support both XLR and 3.5mm microphones.		 1. Check physical connections (jacks must be correct).

2. Check gain and volume (MIC volume, gain knob, phantom power switch).

3. Verify microphone hardware compatibility (3.5mm/XLR/USB limitations).
Microphone output/recording issue Q3: Why can't my voice be heard by the audience or in the recording software during live streaming or recording? 1. Please check if the "REC (Recording)" or "OUTPUT (Output)" knob on the sound card panel is turned on. Turning it clockwise increases the output volume.

2. Please check the audio settings of your computer or live streaming software, ensuring that the default recording/input device is set to "MAONO AU-AM200 / AME2 / E2 GEN2".

3. If using a mobile phone for live streaming, please ensure the connection cable is plugged into the sound card's "POD OUTPUT" or "LIVE OUTPUT" port.		 1. Check the sound card's master output control (REC/OUTPUT knob).

2. Check the system input device selection on the computer/software.

3. Check if the mobile phone's live streaming cable is plugged into the dedicated output port.
Monitoring issue Q4: Why can't I hear any sound (including microphone and accompaniment) through my headphones 1. Please check that your headphones/microphone are plugged into the correct port.

2. Check that the "MONITOR" or "Volume" knob on the panel is turned up.

3. Check if the monitoring function has been accidentally turned off. You can press the "MONITOR" / "Light" button on the panel to re-enable the sound card's headphone monitoring function.		 1. Check the headphone jack position.

2. Check the monitor volume knob.

3. Check the status of the monitor switch on the front panel.
Music input issue (unaccompanied) Q5: Why is there no sound when I play the accompaniment music? 1. Please check that the external audio source (phone/computer) is correctly connected to the sound card's "Music Input" or "AUX-IN" jack.

2. Ensure your phone is successfully connected to the sound card's Bluetooth. Please note that the sound card's Bluetooth only supports receiving external accompaniment audio and cannot be used to transmit microphone sound to Bluetooth headphones/speakers.

3. Check the "MUSIC" or "AUX" accompaniment volume control knob on the sound card panel to ensure it is turned on.

4. Check if the "LOOP BACK (internal recording)" function is enabled (if playing accompaniment on a computer).		 1. Check the physical connection or Bluetooth pairing of the input audio source.

2. Clarify the Bluetooth function's purpose (it only supports receiving backing tracks, not wireless microphone transmission).

3. Check the backing track volume control and internal recording switch.
noise problem Q6: Why is there a lot of noise or static in my recording/live streaming audio? 1. Ambient Noise: The microphone is quite sensitive; please use it in a quiet environment. You can filter ambient noise by pressing the "DENOISE" or "NOISE REDUCER" button on the sound card panel (some models have two levels of noise reduction, which can be adjusted as needed).

2. Current Noise: If the sound card is connected to a power cord for charging while live streaming/recording, current noise may be generated due to the power supply environment. It is recommended to disconnect the charging cable or add a grounding isolator to the computer/sound card.		 1. Use the noise reduction function key on the panel to filter background ambient noise.

2. Investigate the current noise caused by the charging and audio circuits sharing a common ground (disconnect charging or add an isolator).
iPhone/iPad connection issue Q7: How do I connect my iPhone or iPad to an audio interface for recording or live streaming? 1. Lightning Interface (iPhone 14 and below): Connect the sound card's output port (POD/LIVE OUTPUT) using the included 3.5mm audio cable, then connect the phone using an original Apple 3.5mm to Lightning adapter.

Alternatively, use the included USB-C to Lightning adapter to directly connect the phone to the sound card's USB-C data port. (Note: Non-original or uncertified adapters may cause recognition issues or instability.)

2. Type-C Interface (iPhone 15 and above/New iPad): You can directly use the phone's original Type-C data cable to connect to the sound card's USB-C data/live port.		 1. Differentiate between Lightning and Type-C interfaces.

2. Emphasize the importance of original/official certified adapter cables.

3. Clearly define the corresponding sound card interfaces (audio ports vs. data ports).
Connection issue with Android devices Q8: Why can't I record properly or there is no sound after connecting my Android phone to the sound card? 1. Please check your Android phone's system settings to ensure that the "OTG" function is enabled (some Android phones, such as OPPO/VIVO/OnePlus, require OTG to be manually enabled; otherwise, external USB audio devices cannot be recognized).

2. If there is still no sound even though OTG is enabled, please check if the "REC (Recording)" or "OUTPUT" knob on the sound card panel is turned on.		 1. Check the OTG permission switch specific to the Android system.

2. Check the output volume of the sound card.
Special effects and sound effects issues (echo/reverb/side chain) Q9: My voice sounds like it has a heavy echo or reverberation. How can I remove it? What is the purpose of "SIDE CHAIN"? 1. Eliminate reverb: Check the "EFFECT/REVERB PRESETS" button on your sound card panel. Press it until it switches to pink/yellow, or you hear "Original" in the in-ear monitor; simultaneously, turn the "ECHO" knob on the panel to its lowest setting.

Sidechain function: "SIDE CHAIN" is mainly used for scenarios where you speak while listening to background music. When enabled, the system will automatically lower the background music volume to highlight your voice whenever you speak into the microphone; the background music volume will automatically return to normal when you stop speaking.		 1. Switch to "Original" mode with one click and turn down the reverb knob.

2. Explain the application scenario of the sidechain (dodge) function (to reduce background noise and highlight vocals).
Software and device compatibility issues Q10: Is the sound card compatible with game consoles such as Xbox? Can it be used with MAONOLINK/ARENA software? 1. Game Console Compatibility: We apologize, but this series of sound cards is currently not compatible with some closed system game consoles such as Xbox.

2. Software Compatibility: This sound card uses an integrated audio interface (hardware control) and is not compatible with proprietary adjustment software such as MAONOLINK or ARENA. All volume, sound effects, and functions are adjusted directly on the physical sound card panel.		 1. Clearly state the limitation of not supporting Xbox.

2. Clearly state that this type of sound card does not require and cannot be adjusted through the official PC driver software.
