How to Set Up a Streaming Microphone: Step-by-Step Guide

Getting your microphone working correctly for a live stream involves more than plugging in hardware. You need to route the signal into your streaming software, set the gain to a broadcast-ready level, activate noise cancellation, and confirm you can monitor yourself without delay. This guide walks through each stage of that process using the Hollyland LARK MAX 2 for desktop streaming and the Hollyland LARK A1 for mobile streaming, so every step maps directly to real hardware you can follow along with.

What You Need Before You Start

Before moving to Step 1, confirm you have the following on hand.

Hardware:

• Hollyland LARK MAX 2 kit (transmitter, receiver unit, OWS monitoring earphones, USB-C charging cable) for desktop or camera-based streaming 

• Hollyland LARK A1 kit (transmitter, USB-C receiver) for smartphone streaming; Plug and Play with no driver or app required 

Software:

• OBS Studio (latest stable version) or Streamlabs for the same audio settings path 

• Hollyland LarkSound/HollyAudio app (iOS or Android) for LARK MAX 2 gain and noise cancellation controls 

• Windows Sound Settings or macOS System Preferences – to verify device recognition before opening OBS

Step 1 — Connect Your Microphone to Your Streaming Device

Physical connection determines which device name appears in OBS. Getting this step right means you will see the correct input in the dropdown later and won’t need to troubleshoot a phantom “undetected mic” issue mid-stream.

For the LARK MAX 2 (desktop path):

1. Clip the LARK MAX 2 transmitter to your clothing (upper chest area – more on exact placement in Step 6).

2. Power on the transmitter and receiver (see the pairing section below).

3. Once paired, connect the receiver directly to your desktop computer using the USB-C cable.

4. Next, ensure the mic is showing up as your input device. To do that:

On Windows:

• Search and open Settings.

• Choose “System” and click on the "Sound" option on the left-side menu.

• Scroll down to the "Input" section. Click on the dropdown menu and choose the Hollyland LARK MAX 2.

On Mac:

• Click on the "System Preferences" option 

• Select "Sound" and confirm your mic.

For the LARK A1 (mobile path):

1. Power on the LARK A1 transmitter.

2. Plug the USB-C receiver directly into the USB-C port on your laptop or phone.

3. The device is recognized instantly as a USB audio input – no driver installation required.

4. Confirm recognition in Windows Sound Settings or macOS System Preferences before moving to OBS.

Pairing the LARK MAX 2 Transmitter and Receiver

The LARK MAX 2 uses auto-pairing, which handles the link between transmitter and receiver automatically under normal conditions. But if the transmitter (TX) and receiver (RX) units are not paired automatically, here's what you need to do.

1. While the transmitter is powered off, hold the power button for 6 seconds until the blue LED starts flashing.

2. Now, under the powered-off state, hold the camera receiver's power button for 6 seconds.

3. Both units search for each other automatically. To confirm that both units are paired, check the LED light. If it's steady blue on both units, that means the TX and RX units are successfully paired.

4. Speak a short phrase and check the receiver’s signal indicator to confirm audio is being transmitted.

5. 
   

Charging and Readiness Indicators

Before going live, verify that the transmitter has sufficient battery charge.

• The USB-C charging port is located on the base of both the transmitter and the receiver.

• While charging, the LED flashes to indicate active charging.

• When fully charged, the LED switches to solid (no flashing).

• A low-battery warning is displayed as a rapid-flash LED pattern distinct from the pairing-search flash; if you see this before a stream, charge for at least 20 minutes before starting.

Step 2 — Select Your Microphone as the Audio Input in OBS Studio

With hardware connected and recognized by your operating system, the next step is pointing OBS to the correct input device and setting the sample rate to match the LARK MAX 2’s native specification.

1. Open OBS Studio and navigate to Settings (bottom-right of the main interface).

2. Select the Audio tab from the left-hand settings menu.

3. Set the Sample Rate dropdown to 48 kHz. This matches the LARK MAX 2’s native 48 kHz / 32-bit Float output rate and prevents any internal resampling that could degrade audio quality.

4. Under Mic/Auxiliary Audio Device, click the dropdown and select the mic (LARK MAX 2). Or, if you are using the LARK A1 directly via USB-C, select the USB audio device name that appeared when you plugged in the receiver.

5. Click Apply, then OK to close the settings window.

6. Back on the main OBS screen, locate the Audio Mixer panel (bottom center). You should see your mic input listed with a green level meter.

7. Speak into the LARK MAX 2 transmitter at your normal streaming volume. Watch the meter:

• Too quiet: The bar barely moves or stays below -30 dB.

• Good range: The bar peaks between approximately -18 dB and -12 dB during normal speech.

• Clipping: The bar hits red at the right edge. 

Pro Tip: If the mic name appears in OBS but the meter shows no movement, check that the LARK MAX 2 receiver and transmitter LEDs are both showing solid blue (paired), and that the mic is correctly connected to your PC.

Step 3 — Set Gain and Enable AI Noise Cancellation

Proper gain setting and noise cancellation happen at the hardware level through the Hollyland companion app. Configuring both before you layer OBS filters gives you a clean baseline signal to work from.

Adjusting Gain via LarkSound App:

1. Open the Hollyland LarkSound app (HollyAudio app)  on your iOS or Android device and navigate to the connected LARK MAX 2 device screen. The app connects to the receiver.

2. Set gain: Locate the gain slider on the device control screen. Have someone speak into the transmitter (or clip it to yourself and speak at your regular streaming volume) while watching the OBS audio meter in real time. Adjust the gain slider up or down until your voice peaks consistently between -18 dB and -12 dB in OBS. This range leaves headroom above your voice for louder moments without risking clipping. Contrarily, you can use the Dynamic Gain option and choose from the High, Medium, and Low levels.

Adjusting Gain directly from the Camera receiver of LARK MAX 2:

• Press the Control Knob on the camera RX.

• Rotate the dial/knob until you see the "Mic Settings" option on the OLED display. Tap to enter it.

• Tap "Mic Gain" and adjust the gain level accordingly.

• You can choose the "Dynamic Gain" option to automatically adjust the gain for both transmitters. Or, you can select the custom gain option to manually configure gain for each transmitter.

3. Enable AI Noise Cancellation: Locate the noise cancellation toggle in the HollyAudio app and switch it to ON. 

You can also directly turn on/off noise cancellation from the transmitter by pressing the power button once during the recording.

Or, simply tap the active mic on the camera RX to open its dedicated settings, and tap the Noise Cancellation icon to enable or disable it. And to confirm whether the noise-canceling is working, check your LED indicator; the lights should turn steady green.

When active, the LARK MAX 2 processes fan noise, keyboard clicks, room echo, and ambient hum at the hardware level before the signal even reaches your computer or any other recording device. This is the most effective point to remove these noise sources because no re-encoding or software processing is involved.

4. Check the mute toggle: Press the power button on the transmitter 2 times to mute the mic. The TX LED will change to solid red. Press it again to unmute. Confirm the transmitter is in the active state before starting your stream.

Gain-setting logic in brief: The goal is for your speaking voice to occupy the loudest portion of the -18 dB to -12 dB range during normal delivery. If your stream includes louder moments, such as sudden reactions, co-host interruptions, or gaming reactions, peaks slightly above -12 dB are acceptable as long as the signal does not hit -9 dB or red on the OBS meter during normal speech.

Step 4 — Apply Audio Filters in OBS (When to Layer, When to Skip)

OBS audio filters add a second processing layer on top of whatever the hardware is already doing. When used correctly alongside the LARK MAX 2’s AI Noise Cancellation, filters polish the final signal. When both are applied at full strength simultaneously, they can create a processed, hollow-sounding artifact in the audio.

To add filters in OBS:

1. In the OBS Audio Mixer, click the three vertical dots button  next to your mic input and select Filters.

2. Click the + icon in the lower-left of the Filters window to add a filter.

3. Add filters in the order shown in the table below.

Filter settings by hardware noise cancellation state:

When the LARK MAX 2’s AI Noise Cancellation is active, the incoming signal is already clean. Adding OBS Noise Suppression on top introduces a second noise-removal pass that often results in metallic or warbling artifacts, particularly on sibilant sounds. The recommended approach is to run the Noise Gate (to cut the signal during silence) and a light Compressor (to even out volume inconsistencies) without adding Noise Suppression when hardware NC is on.

If you prefer to run without hardware NC for instance, in a treated recording space where ambient noise is already controlled – enable RNNoise in OBS for software-side suppression, then add the gate and compressor.

Step 5 — Monitor Your Audio While Streaming

Monitoring lets you hear exactly what your microphone is capturing in real time, so you can catch problems (wind noise, a loose cable, accidental muting) before your audience hears them.

Step 5 — Monitor Your Audio While Streaming

There are two options available when using the LARK MAX 2: wireless monitoring and OBS software monitoring.

Wireless monitoring path (recommended):

1. Put the earphones inside the charging case with the lid kept open.

2. Press the physical button on the OWS earphones three times to change between available modes. Watch for indicators, as the blue light shows Bluetooth and the white shows 2.4GHz. 

3. Then, select the mode that matches your recording or monitoring setup.

4. Press and hold the same button to activate pairing mode. Also, set your camera receiver into pairing mode at the same time.

5. Both devices will connect automatically without any extra manual steps.

6. Once paired, you can monitor your audio in real time easily.

You will hear your microphone signal immediately, with no perceptible delay.OWS earphones provide zero-latency because you are monitoring the audio before it is digitally encoded and processed by OBS. Also, the output does not affect the signal being sent to OBS or your stream, as they both operate independently. You can monitor while OBS records and broadcasts normally.

OBS software monitoring path:

1. In the OBS Audio Mixer, click the three vertical dot button next to your mic input and select Advanced Audio Properties.

2. In the Audio Monitoring column, change the setting for your mic input from “Monitor Off” to Monitor and Output.

3. OBS will now route the mic audio to your default system output (headphones or speakers) in addition to the stream.

4. Be aware that OBS monitoring introduces a small but noticeable latency – typically between 50 ms and 200 ms, depending on your buffer settings. If you find yourself hesitating mid-sentence or speaking in an unnatural rhythm, switch to the wireless monitoring path via the OWS earphones.

Pro Tip: Most streamers who wear the LARK MAX 2 throughout a session find wireless monitoring via the OWS earphones more comfortable for extended use, since there is no lag feedback loop to adapt to.

Step 6 — Position Your Lavalier Transmitter for Streaming

Placement affects both signal quality and visual presentation on your face-cam. A few small adjustments here prevent volume inconsistencies when you turn your head and eliminate common clothing rustle artifacts.

• Optimal placement: Clip the LARK MAX 2 transmitter to your upper chest, approximately 15 to 20 cm (6 to 8 inches) below your chin. At this position, the capsule picks up speech consistently regardless of whether you lean toward or away from your monitor.

• Clothing rustle: Attach the included foam windshield to the transmitter capsule before clipping. The foam dampens fabric contact noise directly at the source. If residual rustle remains, the LARK MAX 2’s AI Noise Cancellation will further suppress it before the signal reaches OBS.

• Seated desk streaming: After clipping the transmitter near your collar, watch the OBS audio meter while deliberately turning your head left and right (as you would when looking at secondary monitors). Confirm that the meter level stays consistent. A significant drop when turning suggests the transmitter is too low on the chest or is being partially covered by fabric when you move.

• Standing or walking streams: For streamers who move around the frame – unboxing content, room tours, or standing desk setups – clip the transmitter slightly higher (closer to the collarbone) to maintain consistent capsule-to-mouth distance across a greater range of body positions.

Mobile Streaming Setup – LARK A1 with Your Smartphone

For TikTok LIVE, Instagram Live, or YouTube Live from a phone, the LARK A1 offers a direct, zero-configuration connection path. No  driver, and no companion app setup is required.

1. Plug the USB-C or Lightning receiver into your smartphone's charging port.

2. Once plugged in, the receiver will turn on automatically, and the LED indicators will start blinking in blue.

3. Press the power button on the transmitter for 3 seconds to turn it on. Once both units are powered on, they will pair automatically, and the blinking blue LED indicator will turn into a steady blue light.

And your phone immediately recognizes the LARK A1 receiver as an audio input device. No app installation or permission prompt is required beyond the standard accessory connection dialog on iOS.

4. Set noise cancellation level: Press the noise cancellation button on the USB-C receiver to activate it. Or, use the Hollyland LarkSound (HollyAudio) app to select three noise-canceling levels:

• Level 1 (Low): Minimal processing – suitable for quiet indoor environments.

• Level 2 (Medium): Moderate noise reduction – good for home offices with background noise.

• Level 3 (High): Aggressive suppression – use for outdoor or high-ambient-noise streaming environments. 

5. Open your streaming app – TikTok LIVE, YouTube Live, or Instagram Live. The LARK A1 is automatically selected as the active microphone input. No manual selection is required.

6. Confirm the signal in the app’s pre-stream audio check screen (available in TikTok LIVE Studio and YouTube Live’s pre-stream monitor). Speak at your streaming volume and confirm that the level meter responds.

Note: If your smartphone uses a Lightning port rather than USB-C, you can purchase the Lightning receiver variant of the LARK A1..

Troubleshooting Common Streaming Microphone Setup Issues

FAQs

Can I use a wireless lavalier microphone for PC streaming?

Yes. A wireless lavalier microphone like the LARK MAX 2 connects to a PC streaming setup via USB. You can plug the receiver straight into an available USB-C on your computer. Once done, OBS will detect the mic as a primary input device. If not, you can configure the microphone from the settings. 

What sample rate should I use for streaming audio in OBS?

Set OBS to 48 kHz. Most streaming platforms – including Twitch and YouTube Live – use 48 kHz audio, and the LARK MAX 2 natively outputs at 48 kHz / 32-bit Float. Matching the sample rate at every point in the chain prevents OBS from internally resampling the signal, which can introduce subtle audio quality degradation over a long stream.

Should I use wireless mic’s noise cancellation, OBS noise suppression, or both?

Use your microphone’s noise cancellation feature as your primary tool. When the LARK MAX 2’s AI Noise Cancellation is active, it removes keyboard noise, fan hum, and room echo before the signal reaches OBS. Running OBS Noise Suppression on top of this creates a double-processing effect that often produces metallic audio artifacts. Keep OBS Noise Suppression off when hardware NC is enabled, and add only a Noise Gate and light Compressor in OBS (if needed).

Can the LARK MAX 2 record audio locally as a backup while I stream?

Yes, the Hollyland LARK MAX 2 records audio directly inside each transmitter’s built-in storage. This keeps a local copy at full 32-bit float quality during recording. Even if your live stream fails or OBS settings break, the audio is still safely saved. If a stream cuts out mid-session, the onboard file works as a backup. You can later match it with screen recordings or VOD during editing.

How do I stop my streaming microphone from picking up keyboard and mouse sounds?

Start with the LARK MAX 2’s AI Noise Cancellation enabled in the Hollyland LarkSound app or through the TX/RX units.– This feature is specifically effective against repetitive mechanical sounds like keyboard clicks. For physical reduction, position the transmitter higher on your chest (closer to your mouth) rather than near desk level, which increases the distance between the transmitter and your keyboard. If you are running without hardware NC, add OBS RNNoise suppression and a Noise Gate set to close at approximately -40 dB during silent pauses.

Conclusion

Streaming microphone setup follows a simple six-step order each time. First, pair the transmitter and receiver together. Next, connect it to your streaming device. Then choose the right input in OBS and match the sample rate. After that, adjust the gain and turn on noise cancellation in the Hollyland HollyAudio app (also known as the LarkSound app). Set up monitoring and place the transmitter correctly on your body. Once done, the system keeps pairing saved. OBS settings also stay stored, so later sessions need only a quick LED check and gain check before going live.
