What's new in release 4.7.1?

Firmware 4.7.1 is a maintenance release that includes an important stability fix for AFU for your Pearl-2 and an important BIOS update.

What's fixed

AFU to SFTP server stability improvement

The stability of automatic file uploads (AFUs) to SFTP servers has been improved.

BIOS update to resume status after a power cycle

This BIOS update corrects the power cycle behavior of Pearl-2's purchased after August 2018 and older units that were updated with the last BIOS update. With this BIOS update, Pearl-2 returns to same status that it was in before an unexpected power loss. So if there's an unexpected power lose while Pearl-2 is recording (or streaming), when power is restored, Pearl-2 resumes recording (or streaming).

Pearl-2 User Guide Start here

Start here

Welcome, and thank you for buying Epiphan Pearl-2™, Pearl-2 Rackmount™ or Pearl-2 Rackmount Twin™. You'll find information on how to set up and use all three models in this user guide. Whenyou see the name Pearl-2 used in this guide, it means that the content applies to all three models. Differences are explicitly called out. For a product description, see What is Pearl-2?.

See the Quick start for basic steps to get a single video source (and optional audio) set up so you can stream and record some output right away. The rest of the guide shows you how to tweak the system exactly how you want it so you can take advantage of the many advanced features.

About this Guide

After the introductory section and quick start, the next chapter describes the main user interfaces that are used to operate and configure Pearl-2. You'll find everything that you need to successfully access and use these interfaces:

l Touch screen

l Admin Panel

l Epiphan Live

The rest of the user guide covers setting up and operating your system for a successful video switching, recording, and live streaming experience. The chapters are organized in to these five categories: Setup,

Capture, Stream, Record and Maintenance.

Pearl-2 User Guide What is Pearl-2?

This guide assumes that all feature add-ons for Pearl-2 are activated. If a documented feature or task is only available when a specific feature add-on is activated, it is indicated by a link to the activation page for that feature add-on. For the 4K add-on, the link is 4K .

What is Pearl-2?

Pearl-2 is a versatile live video production device that's a video encoder, video streamer, live switcher, and video recorder all in one. Pearl-2 comes in three models.

Pearl-2

A small, silent, portable

system that comes with a

hard-shell carry case.

With Pearl-2, you can capture, record, and stream from computer monitors, radar displays, or almost anything that outputs to SDI, HDMI™, USB, HDMI 4K4K or DVI-I(single link). Capture audio from XLR, RCA,, USB, SDI or HDMI sources.

Simultaneously capture up to six full HD video sources or up to four 4K sources if you have the 4K feature add on installed. You can create up to five simultaneous channels for live switching, or a single 4K channel. Have separate ISOs or create custom layouts with multiple video sources and picture in picture. You can do all that with Pearl-2.

Easily watch live streams using your favorite web browser or media player on mobile devices and computers connected to the same private network as Pearl-2 or using Content Distribution Networks (CDNs). Recorded files can be downloaded via FTPor set to automatically upload via FTP, RSYNC, or CIFS and can be integrated into your Content Management System (CMS). Pearl-2 is also fully integrated with Kaltura CMS and can be registered as a video encoder resource for easy lecture capture.

A 2U rackmount system with all the

Pearl-2, but designed for installation

Pearl-2 Rackmount

same functionality as the portable

and operation in a rack.

Pearl-2 Rackmount Twin

A high density 2U rack mount

variation that contains two complete

(and independent) Pearl-2 systems.

Network security compliance with 802.1x protocols, passwords, and certificate authentication means an easier setup for IT friendly live streaming over enterprise networks. HTTPS enabled for secure administration and control over the LAN, and RTMPS support for secure, encrypted live streaming.

Pearl-2 User Guide Feature add-ons

Pearl-2 does not capture from HDCP encrypted sources.

Feature add-ons

Pearl-2 offers add-on features so you can do even more with your system. Start from the base model of Pearl2 and add feature add-ons for extra functionality.

See Add-ons overview for details about the availability of add-ons for your system, as well as instructions to purchase and install add-ons.

Where you see this symbol 4K in the guide, that means the feature or function applies only if you have activated the 4K feature add-on.

Pearl-2 User Guide Quick start

Quick start

This quick start uses the default settings where possible so you can quickly start using your Pearl-2. The instructions apply to all Pearl-2 models; however, rackmount installation is not included here, see Rackmount

installation.

For the Pearl-2 Rackmount Twin , you cannot plug a source into one system and use it from the other.

Before you start, make sure you have:

l A video source such as a camera or a computer and cables to connect them to Pearl-2. For HDMI, the

source must not be HDCPprotected.

l An audio source coming from either your SDI , USB videoorHDMI video source (must not be

encrypted). Optionally, audio from a different source, such as an audio mixer that you connect to the audio input ports can be used.

l Local area network that uses Dynamic Host Configuration Protocol (DHCP) is preferable.

l Computer with a web browser connected to the same network. We'll call it the “admin” computer.

Starting up!

Pearl-2 is pre-configured with two plug and play channels: Auto A and Auto B. Auto channels are used for this quick start. They have automatic video sensing, which detects the video signal you connect to the video input ports on Pearl-2.

The first video source you connect while Pearl-2 is powered on is automatically assigned to the Auto channel (either Auto A or Auto B, depending in which row you connect the video source). For example, when you first start Pearl-2, the video sources you connect to the HDMI-A and HDMI-B input ports appear automatically in Auto A and Auto B channels (respectively). If no video source is connected, a standard No Signal screen displays.

With auto channels, audio from the connected SDI,HDMI, or USB video source is automatically applied to the channel without needing any additional configuration. For SDIorHDMI audio, just make sure it's unencrypted.

The Auto channel's frame size is set to match the video source by default and the best bit rate for the default frame rate of 30 fps is applied automatically.

For details about Auto channel defaults, behavior, and audio source priorities, see About automatic channels

Auto A and Auto B.

To get started quickly with auto channels:

Pearl-2 User Guide Quick start

1. Turn on your camera or video source and connect the output to one of the video input ports labeled

"A" on the back panel of Pearl-2.

2. (Optional) Connect a second video source to one of the video input ports labeled "B".

3. (Optional) Connect audio to the XLR left/right stereo pair audio input ports on the back of Pearl-2 or to

the RCA stereo pair audio input ports.

4. Connect the Ethernet cable to Pearl-2 and to your network.

5. Connect the power cable and plug it into a power source.

6. Press the power button on the front panel to turn on the system. Wait for the power-up cycle to

complete.

The Grid view showing both channels appears on the touch screen. The video source you connected to the "A" row appears in the Auto A channel, and the video source connected to the "B" row appears in the Auto B channel.

7. Use the touch screen on Pearl-2 for confidence monitoring. To display the single Channel view, simply

tap on one of the channels that you see in the Grid view. From the Channel view, you can do things like stop and start recording for the

8. (Optional) Plug headphones or speakers into the 3.5 mm stereo audio jack on the front ofPearl-2 to

monitor the audio.

My network IP address and channel monitoring

Pearl-2 User Guide Monitoring audio

Monitoring audio

Pearl-2's front panel includes a 3.5 mm audio jack for monitoring audio. You can plug external speakers or headphones into the 3.5 mm audio jack. To monitor the audio for a channel, just select the channel using the touch screen. The audio you hear depends on which layout is currently live because different layouts can have different audio sources configured.

Adjust the volume

Tap the headphones icon on the touch screen to adjust the volume. Each tap increases the volume by 25% to a maximum volume of 100%. Tapping the headphones icon when the volume is at 100% mutes the volume. You can also long press the headphones icon to mute and unmute the volume.

Selecting an audio source

You can choose the audio source for a channel using the Admin panel and can have a mix of several different audio sources. Select your audio sources from connected video sources (SDI, HDMI, USB video/audio), as well as the XLR and RCA analog audio input ports.

There are:

l Four XLR professional line-level inputs + 4.0 dBu up to 12.3 V RMS, (+24 dBu) that support balanced

and unbalanced signals.

l One stereo pair RCA consumer line-level input (-10 dBV)

l Two USB video/audio ports

l Four HDMI ports

l Two SDI ports

The four XLR audio inputs are configured as two stereo pairs by default: XLR A (left/right) and XLR B (left/right), see Configure audio ports for stereo or mono. The XLR B audio ports and the RCA audio ports are linked. You can configure Pearl-2 to use both or just one of the audio sources using the Admin panel, see

Assign audio sources to an input.

Audio for Auto channels are selected automatically.

This table offers some guidelines for adjusting the gain of the XLR and RCA analog audio input ports, as well as the USB ports. Add the suggested gain to the audio input to get an average signal to register at a nominal level in the VU meter (i.e. where the green bars change to yellow). The actual amount of gain needed depends on the strength of the original audio signal. See Adjust audio gain and delay for details.

Connecting microphones to the XLR line level inputs

The four XLR analog audio input ports on Pearl-2 are professional line level inputs rated at + 4.0 dBu up to

12.3 V RMS, (+24 dBu). You can't connect microphones directly to the XLR ports because the microphone signal is too low. If you want to connect microphones to the line-level XLR ports on Pearl-2, you must use an external preamp and boost the mic level signal to the appropriate line level before connecting it to the XLR port.

Optimum CPU performance

Pearl-2, Pearl-2 Rackmount and Pearl-2 Rackmount Twin are powerful live video production systems; however, there's a limit to the number of concurrent tasks the onboard CPU can perform efficiently.

The number of concurrent tasks depends on many factors, like: how many channels you have, how many layouts you have per channel, how often you switch layouts, is the system resizing (scaling) video sources, what frame rate and bit rate is used per channel, are the video output ports used, etc.

For best results, we recommend keeping Pearl-2's CPU usage under 70%. You can check the Overall system load from the Info page using the Admin panel.

Pearl-2 User Guide OptimumCPU performance

If the system load is higher than recommended, you can:

l Disable the video output port (if unused).

l Remove unused channels or layouts.

l Reduce the number of channels created.

l Ensure video sources come in at the right resolution so that Pearl-2 doesn't have to up scale or down

scale the video source.

Recording using multi-track recorders

From the Admin panel, you can create multi-track Recorders to capture multiple channels and audio sources in a single recording. You can then select which combination of video and audio sources to extract from the recording. This feature is useful when you're capturing a video source and multiple languages from different audio sources. Multi-track recorders appear on the Dashboard if they are configured on your Pearl-2.

Each multi-track recorder has a recording control button to start and stop recording. When a Recorder is not recording, the button is gray and the timer is set to 00:00:00. See Add a recorder to learn more about configuring multi-track recorders using the Admin panel.

To start recording, simply tap the recording control button for that multi-track recorder. The button turns red when the multi-track recorder is recording and the timer's counter increments. Tap the button a second time to stop recording.

Switching / mixing using Epiphan Live

The Live Switcher view in Epiphan Live is a simple interface that lets you live switch between layouts while streaming and recording. To learn how to create different layouts for a channel using the Admin panel, see

Add or edit a custom layout.

Switching between layouts using one of the switcher interfaces, such as the touch screen, does not dynamically update what you see in the other switching interfaces (i.e. Epiphan Live and the Admin Panel). You must manually refresh the other interfaces separately to reflect the current state.
