ZOOM in Seminar Rooms 13 and 14 (INF306) with a laptop (updated March 2023)

This section is old and refers to the time when a PC was provided but the mirroring of monitor and projection screen prevented its use for ZOOM. This should have been changed by the Elektronikwerkstatt by the time you read this so that the monitor and projection screen can be used in 'Extended' mode meaning that the monitor and projection screen are separate..

If this is the case, use the PC provided and refer to the instructions for SR25 with these adjustments:

• Wireless microphone (provided by Herr Schleweis/Elektronikwerkstatt – arrange in advance frank.schleweis@znf.uni-heidelberg.de) output is taken from the loudspeaker output on the media cart. Set the MONICON to -26 and connect to RØDE transmitter #1 and USB power adapter.
• Don't use the BELKIN 5-1 adapter.

Output to MONICON controller

Input 1 from media cart / wireless microphone

Input 2 no longer used

 

Original version of the instructions, using a laptop for presentation / ZOOM:

Trolley top shelf

• 1 floor mat
• Parabolic microphone
• 2 laptops
• RØDE microphone set

Trolley bottom shelf:

• 2 floor mats
• 10 m network cable
• 10 m HDMI cable
• 2x 10 m audio extension cable
• 2x 5 m USB extension

Box of accessories:

• FOSCAM webcam
• LOGITECH Presenter
• Power strip
• USB hub
• USB power
• Long USB–USB-C cable
• USB-C battery
• USB/-C stick
• mouse
• Tape
• Wireless headphones
• XLR–3,5 mm adapter cable
• MONICON volume controller

The administrator sits with both laptops at a side table. The main laptop is for the presentation and ZOOM sharing of the screen, camera and sound. The other laptop is for ZOOM administration and sound monitoring – no video or audio sharing.

The speaker will stand on the side away from the window, near the administrator.

Lay the cables along the wall under the blackboard.

The main laptop is connected to the projector with the 10 m HDMI cable. Sound goes from the headphone socket, over the audio cable, 3,5 mm/XLR adapter to Input 2 of the loudspeaker.

The speaker wears a wireless microphone. The sound comes out of the loudspeaker and the Output socket.

Back of the BehringerDR110DS2 speaker, 14.09.2022:

Output to MONICON controller

Input 1 from media cart / wireless microphone

Input 2 from laptop (ZOOM). Set to 12 o'clock or lower if it buzzes.

 

Remove the plug from the SENNHEISER microphone

The FOSCAM webcam is mounted and taped near the centre of the blackboard. Connect to the main laptop with 2x 5 m USB extensions. Use the admin laptop to adjust the camera to show the speaker and audience.

Use the FOSCAM webcam as 'USB HD camera'.

Push the 6.35–3.5 mm adapter into the XLR plug. Put the XLR plug into the output of the speaker. Plug in the long audio cable and connect to the input of the MONICON volume controller. Connect the MONICON output with a short audio cable to the RØDE transmitter. Connect the RØDE transmitter to the power adapter and switch on with a long press on the Ø button.

The MONICON regulates the volume from the speaker's microphone to match the volume from the parabolic microphone which is weak and non-adjustable. Start with the MONICON set to -26. After the introduction using the parabolic microphone, use the MONICON to adjust the level of the speaker's voice to a similar level of the introduction.

Place the parabolic microphone on a floor mat on the trolley between the front tables at the wall. Connect to the battery with the long USB-C cable. The microphone will be held by hand.

Use the MUTE function on the RØDE receiver  to switch it on and off for the introduction and the questions. It should be OFF during the applause which is very loud.

Share the projection screen

Move the ZOOM video or chat window onto the screen if necessary. These windows won't be seen by the ZOOM participants.

When moving the windows back to the laptop, make one last click on the presentation to make it active for the LOGITECH Presenter.

To end the presentation, press ESC.

To find the optimal MONICON volume controller level

1. Point parabolic microphone at technical area
2. Set room speakers to MUTE on touch panel
3. Clip speaker's microphone to your clothing, as the speaker would
4. Take RØDE receiver to technical area
5. Speaker's microphone and parabolic microphones should be on and on the RØDE receiver should be seen to be unmuted (no crossed-out microphone symbol).
6. Position yourself to look straight into parabolic microphone
7. Speak and adjust MONICON until signal strengths from speaker's and parabolic microphones are the same.
8. Turn the MONICON 5dB higher e.g. balanced level is at -36dB, adjust to 31dB (as the questioners will shout)
9. Reconnect receiver to speaker's laptop.
10. Unmute the speakers on touch panel
