Frequently Asked Questions
We get new questions about ZapperBox all the time, and we will post our answers here as we have them. If you have a question about ZapperBox, please write to us here.
Yes. The ZapperBox M1 has one USB 3.0 port, one USB 2.0 port and one SD-Micro slot. You can see a 360-degree view of the ZapperBox at this link. Scroll down to the second panel.
DVR works with USB drives or the micro-SD card. Both are not needed. DVR requires a minimum storage of 128GB. There is no maximum drive size restriction. See FAQ #22 for more on supported drives. We recommend that the 60-minute pause buffer be disabled when using microSD cards and thumb drives. This will help ensure a long life for such storage.
Currently, each TV requires a ZapperBox. The TV and the ZapperBox need to be connected by an HDMI cable. We plan to add support for multi-room DVRs where two ZapperBox units can view each other’s recordings. A second step after that will be to allow streaming live TV over Ethernet or Wi-Fi without running an antenna cable to each room. A final step will be to not require multiple ZapperBox devices and use apps running on smart TVs. We are working to add these features during 2024 starting with multi-room DVR.
See the “Roadmap” section on our Release Notes page. This feature is referred to as "multi-room DVR, streaming apps".
The Zapperbox will work without an Internet connection. However, there are five reasons for connecting the ZapperBox M1 to the Internet:
1. For software updates. You can always skip some updates and only download essential updates after reviewing the release notes on our website. We plan to keep adding new and interesting features to the ZapperBox via software updates. We recommend keeping your ZapperBox always connected to the Internet.
2. To watch secure content (aka encrypted channel with DRM). However, we will soon provide a software update that will allow encrypted channels to work without an Internet connection.
3. To watch broadband channel. Guide data for these channels comes via your antenna but when you tune to them they play over the Internet. These channels numbers have an 'i' after them, like 12.03i.
4. To download 14-day guide data with a subscription (optional)
5. To watch YouTube content (optional)
The dual-tuner version of ZapperBox has the following advantages:
1. While one tuner is being used to watch TV, the other tuner is used in the background to keep updating guide data being received over the air on other frequencies. This way, whenever you press the guide button, you see the most current guide data.
2. The second tuner can be used to record a program that is not currently being watched.
3. A dual tuner box can record two programs simultaneously while a third pre-recorded program is being watched. A single-tuner device can record one program at a time while another pre-recorded program is being watched.
The 14-day guide data subscription is priced at $29.99/year, for up to two units at the same address. 14-day guide data requires an Internet connection. Devices under the same account, same physical address and same IP address are considered to be at the same address. The fee for additional devices beyond two units is priced at $15/year.
A 14-day guide data subscription allows you to use the following advanced DVR features:
1. Record from the OTA grid guide
2. Record from the search menu.
3. Cover art for recorded shows
Without a subscription, you can still use the following DVR features:
1. Record the current show being watched.
2. Schedule a manual recording by specifying the channel number, date and time.
3. See recorded shows as lists without cover art.

1) We’ll open our box as a developer platform for A/344 app development after we release A/344 support.
2) We plan to add IP controls to our box and will open up the SDK to developers for smart home integration.
Most hard disk drives work with ZapperBox but require an external powered USB hub or external power. Flash drives and solid-state drives do not require external power. So far, all external disk drives that we have tested work fine with the ZapperBox.
The USB ports on the ZapperBox do not supply enough power for hard disk drives. We have tested a few different USB powered hubs for supporting disk drives and they all work fine. Here is one that is Amazon’s Choice and works fine.
microSD cards and thumb drives have a “burnout” problem unless the 60-minute pause buffer is disabled. We have not experienced such problems with SSD (solid state drives) yet. Read about it in this blog post.

3. Passthrough (ZB passes undecoded audio to connected device).
There are two ways to connect the ZapperBox, AVR and TV.
1. Connect the ZapperBox to an HDMI input of the AVR and connect the AVR HDMI output to the TV.
2. Connect the ZapperBox to the TV first and connect the TV to the AVR via an HDMI-ARC (Audio Return Channel) port on the TV.
1. Connect the ZapperBox to HDMI input 1.
2. With the television turned on, press the “settings” button on the remote.
3. Select the “All Settings” option from the on-screen menu.
4. Select the “Connection” option from the on-screen menu.
5. Select the “Device Connection Settings” option from the on-screen menu.
6. Select the “Universal Control Settings” option from the on-screen menu.
7. Select the “MyGica” option from the list of possible devices connected to HDMI.
Once configured, not all LG Magic Remote buttons are recognized by the ZapperBox, but the remote can be used to change channels on the ZapperBox.
An LTE (Long-Term Evolution) filter is typically used to mitigate interference from nearby LTE or 4G cellular signals that could negatively impact the performance of TV signals, especially in areas where these signals are strong. The placement of the LTE filter in relation to a TV signal amplifier depends on the specific situation and setup.
In most cases, it's recommended to install the LTE filter before the TV signal amplifier. Here's why:
1. Filtering Interference: An LTE filter is designed to block out unwanted LTE frequencies while allowing the TV frequencies to pass through. If the filter is installed before the amplifier, it can prevent LTE interference from reaching the amplifier and possibly being amplified along with the TV signal.
2. Amplifying Clean Signal: Placing the LTE filter before the amplifier ensures that the TV signal that is being amplified is already free from LTE interference. This can result in a cleaner, higher-quality signal being amplified, which can lead to better picture and audio quality on your television.
3. Protecting Amplifier: If LTE interference reaches the amplifier, it could potentially overload the amplifier or cause other issues that degrade the TV signal quality. By placing the LTE filter before the amplifier, you're protecting the amplifier from potential interference-related problems.
Here's the typical order of installation:
Antenna --> LTE Filter --> TV Signal Amplifier --> TV or Distribution System
However, every setup can be unique, so it's important to consider your specific situation. If you're unsure about the best placement for the LTE filter in your setup, you might want to consult with a professional who specializes in antenna and signal distribution installations. They can evaluate your situation and provide the most appropriate guidance.
You can also consider using our ZapperBox A1 Antenna by Televes. This antenna has all three components built in: Antenna, LTE filter, and amplifier. It also has a built-in antenna for 4G/LTE routers.
We do not recommend using the 60-minute pause buffer with microSD cards or thumb drives as these do not support high enough lifetime rewrite cycles. Using the 60-minute pasue buffer is recommended for SSD and HDD drives. See our blog post about rewrite lifetime at this link.
To backup your ZapperBox DVR storage media, do the following:
1. Format another drive on your ZapperBox. Let’s call this the target drive.
2. Plug both the source drive and target drives into you PC or Mac.
3. Copy the contents of the “\Android\data\com.bitrouter.zapperbox\files\recordings” folder from the source drive to the target drive's "recordings" folder.
4. Plug the target drive into the ZapperBox to verify the backup worked and all your recordings appear in the DVR library.
5. Remove the target drive and plug your original source drive back into the ZapperBox.
Note: at this time you cannot play these recordings on your PC or Mac because we use a proprietary HLS manifest format to make the recording process more efficient. The ability to play "in the clear" recordings on other devices will be added in the future. You will not be able to play secure (DRM protected or encrypted) content on other devices.
Yes. Press DVR. Select the show being recorded. It will have a red dot next to it. Select "Play" and start watching it.
1. The blue rainbow in the grid guide means that this is a NEXTGEN TV (ATSC 3.0) channel.
2. The purple key means that this channel is encrypted. Eventually, almost all NEXTGEN TV signals are going to be encrypted.
3. The two-sided blue arcs in the info bar imply that this is a NEXTGEN TV (ATSC 3.0) channel.
4. The two-sided white arcs in the info bar imply that this is an ATSC 1.0 channel.
5. The number below the two-sided arcs is the signal quality number. It ranges from 0 to 100. We combine the signal strength (SIG) and signal to noise ratio (SNR) to compute this number. You can see the actual SIG and SNR values by pressing the Zap key on the remote and activating the antenna setup screen.
2. Once it has been installed, open the Sofabaton App.
3. Create or sign-in to your Sofabaton account.
4. On the “Select your device” screen, tap “U Series.”
5. Press and hold the “-“ and “E” button on your Sofabaton U2 remote to pair it, then tap “connect”
6. On the “Devices” page, tap “Add.”
7. Next it will ask you if the device is Bluetooth or Infrared. Tap “Infrared” and then tap “Learn from original IR remote.”
8. Set your ZapperBox remote and Sofabaton remote on a flat surface, about 1-2 inches apart, with their IR sensors facing each other. Once you have them positioned, tap “Next.”
9. Now you will see the Sofabaton key layout on your phone screen. Tap on the key you want to program first.
10. Press and hold the corresponding key on your ZapperBox remote, until the app takes you back to the Sofabaton key layout screen. You will now see that the key you programmed is highlighted green and was programmed successfully.
a. If learning fails, a pop up will briefly appear. Ensure the remotes are 1-2 inches apart and repeat step 10 again.
11. Repeat steps 9 and 10 for each key until you have programmed all the desired keys. Tap “Next.”
12. Name your device, ex: “ZapperBox”, and choose an icon. Tap “Next.”
13. On the small screen on your Sofabaton remote, you will now see “ZapperBox”, in addition to any other devices you have programmed. Use the scroll wheel on the remote to highlight “ZapperBox” from the list of devices.
14. Your Sofabaton has now been successfully set up and ready for use with your ZapperBox.
1. Deletes the channel map. A new channel scan is required after factory defaults have been reset.
2. Deletes the currently cached OTA guide data
3. Deletes all DVR series and scheduled recordings (existing recordings are not erased)
4. Reverts all settings found under the “Setting” menus to their original default state. These include themes, caption settings, language settings, audio settings, and hidden channel settings.
5. Deletes all diagnostic logs. For this reason, it is not a good idea to do a factory reset if you want us to investigate an ongoing issue.
It does not erase or change:
1. The OS and app version. These stay unchanged and are not rolled back to the original versions shipped with the box.
2. Wi-Fi settings or passwords
3. Time settings
4. YouTube settings and account password
5. DRM (secure content) provisioning
6. Recording history
If you have a 14-day guide data subscription the current 14-day guide data is deleted but the subscription remains active and new guide data is loaded when the next guide data update happens.
Unlike HDHR and Tablo that are single point gateway systems and can support only one antenna and one storage device, multiple ZapperBox devices can work like a distributed gateway. They can support multiple antennas and multiple storage devices and share all the storage and antenna feeds across all receivers in the home. See a blog post about this architecture at this link.
Currently, we are selling three ZapperBox models; m1 is a dual tuner device. M2 is a single tuner device and m3 is a client device without any tuner. All three devices can be used in any room to view any channel and any recording from any other device or its own connected storage and antenna. See a comparison between all three devices at this link.
Starting in 2025 we plan to start adding apps for other devices like Roku, Google/Android TV, and other TV operating systems.
