P20-DS

The P20-DS slot 3 holds the P_4K_12G SDI Audio-OPT Combo Card, which provides:

• 4× 12G-SDI inputs (INPUT 9 to 12)
• 4× 12G-SDI outputs for copying the HDMI program outputs (OUTPUT)
• 8× optical fiber output ports (OPT) — routing details below
• 4× 3.5 mm audio jacks: 2× line in + 2× line out (working — embeds into the program signal)
• 2× Dante connectors — dual-redundant Gigabit Ethernet, AES67-compliant, with audio de-embedding/embedding on every input & output (raw audio); de-embedded channels can be routed directly to the Dante network, and channels from an external Dante audio processor can be re-embedded for sending to display/streaming/recording. 32×32 Dante channels @ 48 kHz.

The remaining seven slots are identical to the P20:

• INPUT 1–8: each slot has one DP 1.2 + one HDMI 2.0 connector. Selectable per input — when both connectors have signals, only one can be the active source at a time (the chassis LED above each port shows which one is live).
• INPUT 9–12: four 12G-SDI inputs on the combo card.

The P20-DS organizes its outputs into 4 groups, each with 2× HDMI 2.0 + 1× 12G-SDI + 2× OPT. All connectors within a group carry the same image — the HDMI pair, the SDI, and the OPT pair all output the same program at the same resolution:

• Group 1: HDMI 1 & 2 + 12G-SDI 1 + OPT 1, 2
• Group 2: HDMI 3 & 4 + 12G-SDI 2 + OPT 3, 4
• Group 3: HDMI 5 & 6 + 12G-SDI 3 + OPT 5, 6
• Group 4: HDMI 7 & 8 + 12G-SDI 4 + OPT 7, 8

Group behavior depends on the layer mode:

• 4K · Switcher mode — Groups 1 and 3 are primary. Group 2 copies Group 1, and Group 4 copies Group 3 — so all 8 HDMI / 4 SDI / 8 OPT outputs carry just 2 unique 4K programs. Resolutions for the two primary groups can be set independently.
• 4K · PGM-only mode — Groups 1, 2, 3, 4 each have an independent primary HDMI; the second HDMI in each group copies it. Groups 1+2 share a resolution, and groups 3+4 share a resolution.
• DL mode (Switcher & PGM-only) — Same group-pair resolution behavior as 4K PGM-only.

When an HDMI 2.0 connector is set to a custom resolution, its matching 12G-SDI connector does not output. The 12G-SDI outputs have no HDR or EDID management.

1× HDMI 1.3 dedicated to the Multiviewer. Plug a monitor in here and it shows a tiled grid of every input source plus PVW and PGM thumbnails — so the tech at front-of-house can see what's coming in and what's about to go live, all on one display.

The MVR feed never goes to the LED wall. It's a confidence-monitor feed only. Pick from the built-in layout templates; custom MVR layouts are a P80/Q8 feature.

• Default resolution: 1920×1080 @ 60 Hz
• Frame rate is adjustable

4× HDMI 1.3 AUX outputs. Each AUX is its own second program-style output with its own layer engine — pick any input source, PVW, or PGM and stage it independently of what's on the main LED wall.

Typical destinations: teleprompters, stage-side confidence monitors, lobby displays, ISO recorders, streaming encoders, or a separate room. AUX layers can be scaled, cropped, and positioned just like the main PGM layers.

• Default resolution: 1920×1080 @ 60 Hz
• Maximum resolution: 2048×1152 @ 60 Hz
• Supports interlaced output (1080i, etc.)

For 1080p confidence monitoring, use the MVR output above. For up to 4 independent custom feeds (one per teleprompter, recorder, etc.), use these AUX outputs.

2× Gigabit Ethernet ports — for control and live input view. One works as primary, the other as backup; they share the same IP address and have the same function.

GENLOCK IN + LOOP — BNC sync signal input with a loop-through for daisy-chaining the reference to downstream devices.

IEC C14 inlet with a rocker switch. 100–240 V AC, 50/60 Hz.

Two LED work lights with red pushbutton switches on the rear panel — so you can see the connectors during load-in at a dim venue without pulling a flashlight.
