Product Overview
The PD400W microphone is Maono's new-generation wireless desktop microphone. It supports dual-microphone usage, making it an ideal solution for two-person podcasts or live streams. Two creators can each hold one microphone and connect to the live streaming platform synchronously through a single receiver without the need for an external sound card, simplifying the setup process for your creative scenes.

3. Basics
3.1 Microphone Gain
The microphone supports both manual and automatic gain adjustment modes to meet different usage requirements.
● Manual Gain: Drag the slider to adjust the microphone input gain, with an adjustable range from -18dB to 18dB.
The images above are for illustration purposes only, and the software may be subject to change in future updates.
● Automatic Gain Control (ALC): Automatically adjusts the microphone gain to ensure balanced sound output and prevent low volume or overload distortion. Three gain levels are available: Short Distance, Medium Distance, and Long Distance. Select the appropriate level based on your speaking volume and distance from the microphone.
⚠️Note: Enabling Automatic Gain Control will affect the performance of the compressor and limiter, so these two functions will be temporarily disabled.

3.2 Noise Reduction
The PD400W supports two noise reduction modes: Preset Noise Reduction and Custom Noise Reduction.
● Preset Noise Reduction: Offers three noise reduction levels—Slight, Moderate, and Aggressive—to adapt to different noisy environments.
The images above are for illustration purposes only, and the software may be subject to change in future updates.
● Custom Noise Reduction: If the preset modes do not meet your needs, you can manually adjust the noise reduction level in Custom Noise Reduction mode, with an adjustable range from ndB to mdB.

3.4 Microphone Monitoring
The PD400W is equipped with a 3.5mm headphone monitoring jack for real-time microphone monitoring, and supports multi-channel sound mixing to meet your needs from solo creation to multi-device collaboration.
Headphone Volume
Adjust the monitoring output volume of the current microphone with one click.
The images above are for illustration purposes only, and the software may be subject to change in future updates.
Monitoring Output
Check the audio sources you want to monitor through the current microphone. You can flexibly configure the monitoring output based on different creative scenarios. After checking the corresponding device option, the sound from that device will be output through the headphones.
● Current Microphone (e.g., PD400W-1): Monitor your own voice.
● Computer: Monitor background music, game audio, or call sounds.
● Other Microphones (e.g., PD400W-2): Monitor your partner's voice.

3.5 Internal Recording
The internal recording function effectively prevents material loss caused by wireless interference or camera malfunctions. You can enable or disable this function at any time as needed.
⚠️Note: Internal recording cannot be enabled when the remaining recording time of the TX is less than 30 minutes. Please export the audio files first and then perform the formatting operation.
The images above are for illustration purposes only, and the software may be subject to change in future updates.
Bit Depth
Set the audio bit depth for microphone internal recording. Two options are supported: 24bit and 32-bit float.
● 24bit: Standard audio bit depth, suitable for daily recording needs.
● 32-bit float: Preserves more complete audio information, expanding the scope for post-audio processing.
⚠️Note: Enabling 32-bit float bit depth will increase the file size, thus shortening the total recording duration of the TX.
The images above are for illustration purposes only, and the software may be subject to change in future updates.
File Type
Select the file type for saved internal recordings, with two options available:
● Original File: Raw audio files without any algorithmic processing, retaining the complete original recording information.
● Processed File: Audio files optimized by algorithms, such as noise reduction and scene sound effect enhancement.
Note: The bit depth and file type cannot be modified while internal recording is enable.
The images above are for illustration purposes only, and the software may be subject to change in future updates.
Internal Recording Settings
● Startup Auto Recording: When enabled, the TX will automatically start recording upon powering on.
● Low Power Auto Recording: When enabled, the TX will automatically start recording when the RX battery level drops to 10%, ensuring critical audio material is not lost.
● Loop Recording: When enabled, the device will automatically overwrite the earliest recorded files when the TX storage space is full, continuously saving the latest audio content.
The images above are for illustration purposes only, and the software may be subject to change in future updates.
File Export
Press and hold the microphone's internal recording button for 5 seconds to activate USB Drive Mode. Then, connect the microphone to a computer or phone via a USB cable to export the recorded files.
Storage Space
With 24bit bit depth, the device supports up to XX hours of recording. With 32-bit float bit depth, the supported recording duration is XX hours.To format the microphone's storage space, tap the "Format" button in the upper right corner of the interface.
The images above are for illustration purposes only, and the software may be subject to change in future updates.
3.6 Electronic Pop Filter
Enabling the electronic pop filter function helps reduce the impact of plosive sounds such as "p" and "b", aspirated sounds such as "t", "k", and "h", and high-speed airflow noise caused by close-distance recording on the audio quality.
The images above are for illustration purposes only, and the software may be subject to change in future updates.
3.7 General Functions
Reverb
Reverb function is provided, supporting both Preset Reverb and Custom Reverb modes.
● Preset Reverb: 10 preset reverb levels are available for quick adjustment based on personal preferences.
The images above are for illustration purposes only, and the software may be subject to change in future updates.
● Custom Reverb: If the preset effects are insufficient, enable Custom Mode. 3 groups of savable custom configurations are offered, allowing you to adjust professional parameters such as compression threshold and compression ratio for precise reverb tuning.

Timecode
Timecode is a time marker used for synchronizing audio and video. This function is only supported when connected to the Camera RX.
Timecode Mode
The Camera RX can output timecode to cameras, mobile devices, and PCs. Three timecode modes are supported:
● L-OUT: The receiver outputs timecode in Linear Timecode (LTC) format. Suitable for other devices that support external timecode input.
● A-OUT: The receiver outputs timecode in Audio Timecode (ATC) format. It outputs the RX timecode to devices that do not support external timecode input by occupying the left audio channel.
● N/A: The receiver runs the timecode but does not output it externally; the timecode is only recorded in the internal recording files.
The images above are for illustration purposes only, and the software may be subject to change in future updates.
Timecode Frame Rate
Covers common video frame rates, with a default setting of 29.97F. Ensure the frame rate is consistent across all recording devices during use.
⚠️Note: Switching the frame rate during internal recording will start a new recording session.
The images above are for illustration purposes only, and the software may be subject to change in future updates.
Timing Method
Select the timecode timing method, which defaults to counting from zero. When "Real-Time Timing" is selected, the timecode will synchronize with the phone system time.
Note: Switching the timing method during internal recording will start a new recording session.
