Alfatron 21e-softcodec 2x1 Presentation Switcher Cec
- Product Code: eq102236
-
Designed to switch between an HDMI 2.0 and a USB Type-C input to one HDMI output, the 21E-SOFTCODEC 2x1 Presentation Switcher with CEC from Alfatron supports video resolutions up to 4K x 2K60 in a 4:4:4 color space. The CEC feature enables the device to be controlled by the front-panel buttons or RS-232 CEC commands.
The unit also has two USB type-A data ports for devices such as cameras, microphones, or keyboards, and a USB type-B port for host connectivity. The 21E automatically switches to the first detected source device when set to Auto and to the lowest numbered input when the active source is removed. Stereo and multichannel audio are supported on the HDMI input, which gets embedded in the HDMI output stream while being simultaneously de-embedded to a balanced analog audio output.
Auto Presentation Switcher with CEC Front-Panel Buttons and RS-232 Control HDMI 2.0 and USB Type-C Inputs Supports up to 4K x 2K60 Video in 4:4:4 USB 3.0/2.0 Data Ports

Related Questions and Answers
Q: 1. What frequency do these mics use?
A: The Alfatron USB Conference Device with 4 Wireless Microphones BH #ALFWMP4 operates on 2.4Ghz
Q: 2. In our scenario we would want to have 2 input signals and input one would be feeding both outputs and under fault scenario input 2 would go to both outputs. - Also do you have a computer input card to put second signal back into another computer? Thanks Brent
A: This unit should work for you. It has 2 inputs, with one input going to both outputs and the other input on stand-by. If the first input drops, the 2nd input will take over and be sent to both outputs. We have SDI Capture Cards from Magewell as well.

Q: 3. I can't find anything about the preamp, even on Roland's site. Is there any info about the gain? Take the typical worst case of an SM7B - would I have to use a CloudLifter or similar product?
A: The Roland Web Presentation Dock BH #ROUVC02 • MFR #UVC-02 features a studio -grade microphone preamp with plenty of gain available. No Cloudlifters or similar devices would be necessary for use with microphones like the Shure SM7B or EV RE20.
Q: 4. Does it have the follow you feature? Is it capable of auto-following the moving person?
A: The Alfatron 1080p USB 2.0 PTZ Camera with 10x Optical Zoom (B&H # ALF10XU2CAM) does not have an auto tracking feature.
Q: 5. Is the contact closure remote overide the automatic? Thanks
A: The Kramer 2x1:2 3G HD-SDI Automatic Standby Switcher has Contact closure or automatic switching.
Q: 6. Is the UVC compatible with Zoom?
A: Yes, the Roland Web Presentation Dock BH #ROUVC02 is compatible with Zoom. Per Roland: Plug In and Play: Once connected to your computer via USB, the UVC-02 is instantly recognized as a webcam and audio source, with no drivers or set up required. That means it’s ready to go with popular web meeting software such as Zoom, Microsoft Teams, Webex by Cisco, or any application that uses a webcam as an A/V source for streaming or recording.
Q: 7. What's the interface type for the charging cable? USB-A to USB-C or micro USB?
A: Proprietary USB Receiver and cable.
Q: 8. Will it cause damage to keep this powered on 24/7/365? We have it installed in our employee training room (auditorium).
A: Yes, the KanexPro 8K HDMI 2x1 Switcher should operate without fail 24/7. I would recommend having a spare on hand if it is a mission critical part to your training room.
Q: 9. Does this remote make a "clicking noise" when pressed?
A: There is a slight mechanical click when any of the buttons are depressed, but not a sound through the computer. If you are running a Powerpoint presentation and hear a "clicking noise" from the computer speakers or connected AV system speakers as you advance slides with the remote, check to see if the sound is also heard when slides are advanced using the mouse or keyboard arrows. If so, please check the slide "Transitions" settings in the Powerpoint file. A "Sound" may have been set up for some or all slide changes.
Q: 10. Does this unit handle audio at all?
A: Yes, if its embedded
