The ST-NG1 is a miniature wall and surface mount random noise generator from RDL, suitable as a reference noise source for audio measurements. Additionally, the unit can be used as a masking noise source in engineered sound, or for counter-intelligence applications, particularly where true random noise (occupying the full bandwidth from 20 Hz to 20 kHz) is required.

The ST-NG1 produces no repetitive frequency or amplitude pattern, unlike digitally generated pseudo-random noise generators, which can be decoded and removed by effective intelligence equipment. Limiting circuitry controls extreme peak levels in the audio, while still delivering random variations of at least 20 dB.

Four outputs provide a microphone-level and line-level output from each noise source, with separate and independent gain-trimming potentiometers provided. Each output is balanced and low-impedance and may be wired either balanced or unbalanced, and all outputs can be used simultaneously.

Related Questions and Answers

Q: 1. x or y?

A: The Tentacle Sync E mkII Timecode Generator with Bluetooth 5.0 displays the timecode in position x on the app.

Q: 2. If I have two cameras and an audio recorder, how many of TE2's do I need?

A: You need 1 for every device that does not have a time code input. If you are using cameras/audio recorders with a dedicated time code input you can use 1 Tentacle sync to sync multiple devices but you will need to resync all of your devices every few hours to make sure the time code does not drift.

Q: 3. I intend to use this device for video interviews with the following kit: 1) Nikon Z6II camera feeding video via HDMI into Atomos Ninja V; 2) Tentacle Sync-E with Lavalier mic on subject; 3) Zoom F3 with shotgun mic near subject (not connected to camera or Ninja V). How many of these TC generators would I need? I'm thinking one to sync-jam the Tentacle-E recorder, which would then be connected to the Ninja V while shooting, and one connected to the Zoom F3 (not sure if that recorder will actually accept TC?). Any suggestions? Thanks in advance!

A: Two sounds correct. One Tentacle Sync E mkII Timecode Generator with Bluetooth 5.0 (Single Set) synced with the Zoom F3 which is capturing audio, and one for the NInja V which is capturing video. You can use the Tentacle Sync E mkII with the Ninja V by routing it into the mic/line input. Make sure that the Ninja is set to intake audio from the mic/line port, and then use post production software to sync.

Q: 4. I have 3 Cameras sometimes on set , how many of these devices I should buy ?

A: You should get one Tentacle Sync E mkII Timecode Generator with Bluetooth 5.0 for every device you are planning to sync.

Q: 5. If I am using two mics and connecting one of these to my camera (Canon 5D IV) do I need a 3rd device to sync timecode between two mics and my camera?

A: You will need a device for each item you are looking to sync. If you have 3 separate items, you will need 3 units.

Q: 6. For use with Panasonic GH4 and GH7, will I need to purchase additional cables to connect them to the Synce E's?

A: No, the Tentacle Sync E mkII Timecode Generator with Bluetooth 5.0 (Dual Set) comes with all cables needed to mount to your cameras.

Q: 7. Is the older non Bluetooth version compatible with this mkII version?

A: Yes, one can sync between Tentacle Sync models using a 3.5mm cable when a wireless sync model is not present.

Q: 8. Can I actually generate timecode while charing the device through usb port? It seems to add interference noises and make the recorded timecode unusable.

A: The Tentacle Sync E mkII Timecode Generator with Bluetooth 5.0 (Dual Set) (B&H# TETE2MK2) does have a USB C port that can be used to charge the device. You may be hearing RFI/EMI (i.e. radio frequency or electromagnetic interference). Such interference can often sound like a low or medium frequency hum, although radiated forms (which, by definition, pass through the air) are frequently higher. As for solving the problem, we would recommend not charging it while using it (since it does have a long battery life anyway) or at least using a battery-based source rather than an AC adapter for charging it if you'll be doing so during use. Another good alternative would be to use a USB power bank that does not require a converter (buck or boost) to produce power since those typically do generate EMI pulses. Finally, if you find that the problem exists even if there is nothing plugged into the opposite end of the USB cable from the one that is inserted into the USB C port then you may want to experiment with different USB cables to find one that is not as sensitive to (or is better shielded against) RFI or EMI radiation in the ambient environment.

Q: 9. How would this work with 4 cameras shooting various frame rates at once + 6 external audio devices?

A: It would not be a scenario where you could benefit from using time code. All of your camera frame rates would need to be matching on the cameras you work with.

Q: 10. If I am using two RED Komodos and a MixPre-3 II simultaneously, can I get away with one unit?

A: Sure, you can use a single Tentacle Sync E mkII Timecode Generator with Bluetooth 5.0 (Single Set) to jam sync multiple devices.
