TriCaster Tips & Tricks - Hardware

How can I connect our school's TriCaster to Channel One TVs?

If you have a VCR, you can connect TriCaster's video output to the VCR. The best approach, though, may be to connect TriCaster video out to an RF modulator. Either of these options will then give you TV tuner-compatible output for your classroom TVs.

How do I get my nVidia graphics card to recognize TriCaster as a TV source?

Most modern nVidia graphics cards have an S-Video output you can take advantage of as an alternative to a program like iVGA. Most manufacturers also bundle a small converter dongle that will allow either a composite, component or S-Video signal but you can plug in straight S-Video usually. Your graphics will only output a standard definition (SD) signal and that's all TriCaster can take anyway.

Laptops are generally a bit more friendly when it comes to plugging in S-Video and may simply require a restart if that. Desktop graphics cards can be a little more reluctant to output a signal without detecting a device. Fortunately nVidia has methods around this we can access in the NVIDIA Control Panel.

The following instructions use the latest (as of the time we wrote this) nVidia display drivers v169.21, compatible with all GeForce cards from the MX to 8000 series, your driver version may vary slightly if you're on a different Windows OS than XP 32-bit but the instructions should be the same.

To begin, make sure you have your graphics card TV output interface is connected to TriCaster then right click on your desktop and choose NVIDIA Control Panel. On the left side under Display click on Set up multiple displays, you probably don't see the TriCaster as a generic TV device so under Select which displays you'd like to use choose the option My display is not shown in the list...

This will bring up a window called 'Detect Missing Display', highlight the checkbox towards the bottom called Force television detection on startup and do not choose to restart. The most thorough option to do is to manually shutdown the computer and wait about a minute or so then start it back up.

When you come back to Windows you should get the Multiple Display Wizard, the only options that really concern you is your primary monitor's resolution and what you want your second monitor to display. I recommend either clone (shows the same image your current monitor does) or dual view (essentially makes the TV input a separate desktop).

You should now be able to key up the appropriate S-Video input on your TriCaster and see your computer's desktop now.

How do I protect TriCaster when inserting USB drives?

During a live production, when someone hands the director a USB thumb drive with additional graphics or clips, you can hold down the Shift key when inserting the device in TriCaster. This tells the system NOT to Autorun the inserted device. It is usually when the inserted device is being scanned for executable files that infected files copy themselves to the new system.

What is the best way to get +4dBu audio into TriCaster?

If you are inputting a +4dBu nominal level, you'll need to go to the audio setup tab where the Line, Mic, and Variable options exist on the audio pre-amp, select variable, and turn the knob all the way down. When you put in a +4dBu tone into the XLR or 1/4 inch

Differential inputs, it will read "0" on the VU meters in TC Broadcast.

If you are inputting a -10dBV nominal level, you'll want to select "Line" in the audio setup tab. This assumes you are plugging a single ended signal into an RCA to 1/4 inch adapter and plugging that into the 1/4 inch hole in the XLR Combo. With this setup, when you input a -10dBV signal, it will read "0" on the VU meter. You have the option of selecting "variable" to do fine adjustments if needed. It is preferable to make those adjustments using the variable gain know when possible before using the audio sliders in the other tab of the audio panel.

Finally, if you are using a MIC input, you'll select the MIC button, and phantom power if you are using a powered MIC on the XLR inputs. Phantom power is not applied to the 1/4 inch section.

Input impedance for the audio jacks is about 10K ohms, and output impedance is about 100 ohms.

Can I TriCaster LC-11 with TriCaster 300?

Yes, while the labels of LC-11 do not match what is on screen, you can download the operating instructions here.
