Safety rules

1. Audio Feedback loop
Audio feedback is the ringing noise (squealing, screeching) present in sound systems. It is caused by a “looped signal”, i.e., a signal which travels in a continuous loop and leading to the audio level reaching maximal level. This can cause serious damage to the auditory system, or even lead to temporary or PERMANENT HEARING LOSS.

Feedback might be heard from speakers with one or more of the following conditions:

  • The speakers are close to the microphone
  • The speaker volume is turned up so as the microphone hears the speakers
  • The microphone’s sensitivity is high
  • Turning on the mixer without turning the volume and faders down.

To eliminate feedback, the feedback loop has to be interrupted.


  • Always start the fader at and make gradual adjustments until the desired volume has been reached. NEVER start at maximum level AT ALL TIMES.
  • Change the position of the microphone and speaker so that the speaker output isn’t feeding directly into the mic.
  • Speak too close to the microphone.
  • Turn the microphone off when not in use.
  • Lower the speaker output, so the mic doesn’t pick it up.
  • Avoid aiming speakers directly at reflective surfaces.
  • Use direct injection feeds instead of microphones for musical instruments.
  • Use headset or in-ear monitors instead of speaker monitors.

2. Eyesight Damage
The LED light panel is able to emit strong light and might be able to damage one’s eyesight if under prolonged period of direct exposure. It can cause eye strain or eye floaters if not handled with care.


  • Avoid direct line of sight to the LED panel under high brightness level settings.
  • If direct line of sight is unavoidable, reduce the brightness of the LED panel and take a short break regularly (i.e. 15 to 20 mins).
3. Others 
  • Do not rewire any hardware connections or make unauthorized changes to the control room computer unless instructed or approved by supervising staff.
  • Pay attention to the surrounds when navigating around the podcast studio and avoid tripping wires and cause injuries.

3.1 Display Settings


For this tutorial, we will set the content display of the studio monitor to mirror directly from the control room computer. This is to mimic the case where the host would like to have a live monitor for his/her performance. 

Step 1: Navigate to “Display Settings” by right-clicking on your desktop or by other ways you prefer.

Step 2: Under the “Display” tab, choose “Duplicate these displays” under the “Multiple Displays” item. If the second display is not showing here please make sure the studio monitor is connected to the computer is connected to the control room computer properly and is turned on. Confirm the studio monitor is display the same content as the control room computer monitor. 

The following are a few possible use cases and are briefly discussed as follows:

– The host provided some multimedia files like PowerPoint or videos for display during the session. This settings require an extended desktop with the multimedia content showing on the extended desktop. 

– The host bring in his/her laptop and would like to show the content on his/her laptop on the studio monitor via an HDMI connection. This setting requires HDMI signal capturing and passthrough.

– The host bring in his/her laptop or mobile device and would like to show the content on his/her laptop or mobile device via a wireless connection. This setting require setting up an NDI/Airplay/Miracast signal capturing on the control room computer.

Here is the basic introduction of the hardware and software.

3.1Mixer tutorial

By default, the mixer should have all levels set to -∞ and level for all the monitor device output knob should be set at 0. 

Step 1: Find a video/audio source from online (i.e. YouTube). Play the source so you will have an audio stream to reference from when adjust the mixer. Make sure the audio output device has been set to Zoom L-12 and the volume output is unmuted.

Step 2: For this tutorial, we will be using control speakers and studio speakers for audio monitoring. Adjust the output knob for each device to around 4 or 5. Also make sure the push button under each output device knob is at high level (i.e. it’s outputting audio from the master channel). Mast

Step 3: Make sure you are using the “Master” fader mode. (as indicated by the red arrow on the right). This is to ensure you are adjusting the volume for the master channel. Adjust the slider for channel 9/10 (PC Audio Output) to the level as indicated by the picture below. You should see the volume indicator adjusting accordingly when you move the slider. If the indicator is not lit check your video/audio source

Step 4: Adjust the master slider gradually. NEVER make drastic adjustments. Make sure all the output devices listed in Step 2 can hear the audio component of the video/audio source. Adjust the output volume for each output device from the output device knob if necessary.

3.2 Open Broadcast Studio (OBS)

 OBS is a free and open-source software for video recording and live-streaming. It has the ability to mix different audio visual sources into a live video production environment.

3.2.1 Output Option 1: Record Locally

The video will be recorded to the user’s video folder (“Videos”) by default.

If you would like to change the output path, navigate to “Output” tab in “Settings”, and modify the designated path. This step is not compulsory.


3.3.4 Operation

The following section will describe the procedures for operating OBS with the Elgato Stream Deck. In the demo videos, the stream deck companion app will be used for demonstration, which is a mirror of the actual button layout on the physical Stream Deck Device, which the same action can be performed by pressing the corresponding button on the device.  

Scene Changing and Mute/Unmute Mic: 

The preset scenes introduced in section 3.3.3 have been added to the first row of Stream Deck. Press on the button will perform a transition to the designate scene. 
Three buttons controlling the mic channels have been added to the third row of stream deck. Pressing on the button will mute/unmute individual mic channel. (Note: to identity which number corresponds to which mic, refer to the sticker label on the mic.)

Modify Transition Effect: 

Three transition effects have been added to the second row of Stream Deck by default, i.e. Cut, Fade and Swipe. You can notice after setting the transition effect on the stream deck, the transition effect will be changed accordingly when performing a scene change in the following demo.

To enable or disable green keying, press the corresponding button on the Stream Deck. Notice that this action can be done with all scenes using the USB Camera source. 
To start or stop a recording, press the recording button on the bottom right of the stream deck.

3.3.5 Integration with Zoom or other Conferencing Applications

Other than recording local video files or performing online streaming, this podcast studio can also be used for video conferencing with very little addition setup! This result can be achieved by redirecting the same video output stream used for recording and streaming to a local, simulated virtual “camera”, which can then be used by the conferencing applications as a video input source. The following section depict the steps required for setting up OBS to be used with any conferencing applications.


Step 1: Start OBS VirtualCam

Launch the menu of the OBS VirtualCam via the Tools dropdown menu. Press “Start” to enable the virtual cam.


Step 2: Configure the Video Input on the Conferencing Application 

On your designated conferencing application, select “Line (ZOOM L-12 Audio” as the audio input and “OBS-Camera” as the video input. For demo purpose, the following screenshot shows how to perform such change in Google Meet. After that you are good to go!

Clean Up

– Transfer the video recording files to your own device and delete them from the control room computer. 

– Delete the OBS scene you have created. 

– Reset all the levels and knobs on the mixer back to it’s default value (i.e. – infinity for level sliders and 0 for output device knobs).

– Turn off all the equipment used, i.e. camera, led light panel, studio monitor, control computer, mixer and studio speakers.Here is the basic introduction of the hardware and software.Here is the basic introduction of the hardware and software.


-There is a red video shooting icon with a cross on the camera.

This is an indication that the camera is overheat. If it keeps shutting down in the middle of a shooting, try to lower the resolution setting or turn off the camera to let it cool down.


– I can’t hear any audio from the speakers or headphones.

Make sure the output device has been turned on. Check to make sure the fader level on the mixer has not been set to -∞ and also the corresponding audio channel and the Master Channel has not been muted. If you see the fader level light but you still cannot hear any audio, make sure the “Monitor Out” level know has been adjusted correctly.


– I can’t hear audio play back from computer.

Reference to the previous question first, then make sure the output device has been set to “Line – (Zoom L12 Audio)” on the computer and also the application used for playback (i.e. VLC Player)


– “HDMI in” device functioning correctly but no video signal is show on OBS.


 – Record broadcast has no sound input from the mic and background playback on saved video.

 In OBS Studio, Make sure the eye icon for mic / aux elements under ‘Source’ is not muted. Click on the eye icon to unmute.
