ATEM 2 M/E Constellation HD

The Blackmagic Design ATEM 2 M/E Constellation HD is a 1RU live production switcher built for serious multi-camera broadcast in Bangladesh — TV stations, OB vans, mid-to-large house-of-worship installs, and stadium-class event production. With 20 × 3G-SDI inputs, 12 × 3G-SDI outputs, 8 upstream + 2 downstream keyers, a 48-channel Fairlight audio mixer, and two 16-view multiviews, it consolidates a full broadcast gallery into a single rack unit.

Key Specifications

What's in the Box

• ATEM 2 M/E Constellation HD switcher (1RU)
• Welcome wallet with QR code for software download

Hardware control panels are sold separately. See the ATEM 2 M/E Advanced Panel 20 for the matched 2 M/E surface, or the ATEM 1 M/E Advanced Panel 10 if you want a smaller hardware footprint while keeping software access to all 2 M/E features.

How to Use ATEM 2 M/E Constellation HD

Setup

Mount the switcher in a 1RU slot of your broadcast rack, route mains through your studio UPS, and bring SDI in. Each of the 20 inputs has its own frame-rate converter, so cameras shooting different formats lock without an external sync chain. Connect a confidence monitor to the multiview output, route program out to your transmission encoder, and connect a Mac or Windows workstation running ATEM Software Control over Ethernet.

For multi-camera live streaming

Use one SDI program output to your transmission encoder and the USB-C output as a UVC webcam source for OBS, vMix, or a browser-based streaming platform. The USB-C path is ideal for YouTube and Facebook Live — no extra capture card needed. To stream from a remote venue back to a base ATEM, pair with the Blackmagic Design ATEM Streaming Bridge.

For OB van and large events

The 20-input bank handles a full multi-camera shoot — cameras, playback machines, character generator, lower-thirds, and graphics PC. Cable in an ATEM Talkback Converter 4K over SDI for crew comms. Use 8 upstream keyers for layered chroma + luma + DVE composites; reserve 2 downstream keyers for show-wide bug + lower-third overlays.

How It Compares

Step down to the ATEM 1 M/E Constellation HD when 10 inputs and one M/E bus is enough — most single-camera-bus church and conference rigs do not need a second M/E. If ISO recording per input is a hard requirement, the ATEM Television Studio HD8 ISO records every camera as a separate file. For the smallest deployment footprint with HDMI cameras, see the Blackmagic Design ATEM Mini Pro ISO.

Care and Storage

• Mount in a ventilated rack — leave 1U of airflow above and below if possible.
• Keep the unit dust-free; broadcast venues are dustier than they look.
• For OB van and touring use, transport in a foam-lined flight case to absorb road vibration.
• Power through a studio UPS — sudden cuts during a show damage rack switchers more than continuous use.
• When idle for long periods (off-season), power-cycle once a month to keep capacitors healthy.

Frequently Asked Questions

How many SDI inputs does the ATEM 2 M/E Constellation HD have?

20 × 3G-SDI inputs, with a frame-rate converter on every input. It also has 12 × 3G-SDI outputs; program, preview and aux can each be assigned to any of them, and its 2 multiviews show up to 16 views each.

What is the difference between ATEM 1 M/E and 2 M/E Constellation HD?

The 2 M/E doubles the input count (20 vs 10), doubles the upstream keyers (8 vs 4), and adds a second mix-effects bus for layered live composites. Pick the 2 M/E for TV-station, OB-van, and large-event broadcast; the ATEM 1 M/E Constellation HD is the right choice when 10 inputs and a single M/E bus are enough.

Does the ATEM 2 M/E Constellation HD support 4K?

No — this is the HD model. It processes 1080p / 1080i / 720p formats up to 60p in 10-bit 4:2:2. If your workflow is 4K end-to-end, look at the ATEM 2 M/E Constellation 4K instead. Most BD broadcast and live-event delivery is still 1080p, so HD remains the practical choice.

Does the ATEM 2 M/E Constellation HD include the control panel?

No — the box holds the 1RU unit and a welcome wallet with a QR code for the software download. Free ATEM Software Control runs on Mac (14 Sonoma, 15 Sequoia or later) and Windows 10 / 11. For a hardware surface, add the ATEM 2 M/E Advanced Panel 20 separately.

How many keyers does the ATEM 2 M/E Constellation HD have?

10 total — 8 upstream keyers (each capable of chroma, luma, pattern, or DVE keying) and 2 downstream keyers for show-wide overlays like channel logos and persistent lower-thirds.

Is the ATEM 2 M/E Constellation HD good for multi-camera church and event live streaming?

Yes — the 20-input bank, two 16-view multiviews, and 48-channel Fairlight mixer are exactly what large house-of-worship and event teams need. Use the USB-C output to feed OBS or vMix for direct YouTube and Facebook Live streaming alongside the SDI program out for IMAG.

ATEM 2 M/E Constellation HD এর USB-C output দিয়ে কি webcam হিসেবে ব্যবহার করা যাবে?

হ্যাঁ। USB-C port program feed কে UVC webcam হিসেবে present করে, তাই OBS, vMix, Zoom, Google Meet — যেকোনো streaming software এ direct webcam source হিসেবে use করা যাবে। আলাদা capture card লাগে না।

Does it support both Mac and Windows?

Yes. ATEM Software Control runs on Mac 14 Sonoma, Mac 15 Sequoia or later and Windows 10 / 11. The control protocol is the same on both — projects built on one platform open identically on the other.

ATEM 2 M/E Constellation HD কোথায় পাব Bangladesh এ?
