Cisco Codec Pro G2 CS-CPRO-K9 – Standalone Integrator Codec

Product Overview

Cisco Codec Pro G2 CS-CPRO-K9 is the standalone second-generation Pro-class codec for integrator-led room builds, sold as the codec only so the cameras, displays and microphones are specified separately. It drives three HDMI 2.0 outputs, accepts five HDMI inputs plus USB-C and USB-A sources, and carries eight IEEE 802.3bt PoE ports with a 120 W budget for digital microphones and IP peripherals. Cisco positions the platform for high-impact spaces including large conference rooms, multi-camera spaces, training rooms, boardrooms and divisible-room deployments, and names it as the migration product for the end-of-sale Codec Pro. This is a current product with no Cisco end-of-sale bulletin published.

Product Description

Specified as the engine of a custom room, CS-CPRO-K9 gives an AV designer more I/O than the codec it replaces. Five HDMI 2.0 inputs accept up to 3840 x 2160 at 30 fps, with HDMI 1 to 4 also handling 5120 x 2160 at 30 fps and HDMI 4 supporting HDCP 2.3 for protected sources. A USB-C DisplayPort Alt-mode input reaches 5120 x 2160 at 30 fps and a USB-A 3.2 Gen 2x1 input reaches 3840 x 2160 at 30 fps, so laptop and appliance feeds land on the codec without an outboard scaler.

Display output is three HDMI 2.0 ports with CEC 2.0. HDMI 1 supports 7680 x 4320 at 30 fps and 3840 x 2160 at 60 fps with HDCP 2.3, HDMI 2 supports 3840 x 2160 at 60 fps with HDCP 2.3, and HDMI 3 supports 3840 x 2160 at 60 fps, which covers a dual-display front of room plus a dedicated content screen. Audio is built for integration rather than a fixed bundle: four 48V phantom-powered Euroblock microphone inputs rated to 18 dBu, two balanced line-level Euroblock outputs at up to 8 dBu, embedded audio on all HDMI ports with Audio Return Channel on HDMI 1, and AES67 in and out across the PoE ports at eight streams of eight channels.

Network design is where the G2 differs most from earlier Pro-class hardware. One RJ-45 LAN port is joined by a multi-gigabit peripheral port running up to 10 Gb and eight PoE / PoE+ / PoE++ ports sharing 120 W, which lets an integrator run cameras, microphones and control surfaces over structured cabling instead of long HDMI and analog runs. A 4-pin Euroblock GPIO port supplying 12V at up to 0.7 A with an open-drain output sinking up to 1 A gives a documented hardware hook for screen lifts, partition sensors and room control hardware.

The chassis measures 16.9 x 2.6 x 9.9 in. at 6.2 lb and mounts on a wall, in a rack with rack ears, or free-standing. RoomOS 26.5 or later is required, and the codec registers to Webex, Microsoft Teams Rooms, Zoom for Cisco Rooms, Cisco Expressway or Cisco Unified CM v15 SU4 or later. Cisco documents the Quad Camera, Room Vision PTZ and 4K Desk Camera with this codec and states that up to nine cameras can be controlled independently, so browse conference camera hardware alongside the codec. For complete rooms, see large room solutions and video conference systems. Cisco has not published a standalone Codec Pro G2 data sheet: every specification quoted here is drawn from the Cisco Room Kit Pro G2 data sheet, which is where Cisco documents the codec.

Key Features

• Eight PoE++ ports with a 120 W budget — The codec powers and connects up to eight IEEE 802.3bt devices such as digital microphones, Room Navigators and IP cameras directly, removing most local power supplies from the rack.
• 10 Gb IP peripheral port — A dedicated multi-gigabit port carries video over IP, letting cameras and peripherals reach the codec over structured cabling instead of long HDMI runs.
• Five HDMI 2.0 inputs with 5K and HDCP 2.3 — HDMI 1 to 4 accept 5120 x 2160 at 30 fps and HDMI 4 handles HDCP 2.3, so protected sources and ultra-wide laptops connect without an external scaler.
• 8K-capable HDMI output — HDMI 1 supports 7680 x 4320 at 30 fps as well as 4K60, so the codec can drive very high resolution displays in premium rooms.
• GPIO Euroblock control port — A 4-pin GPIO providing 12V at up to 0.7 A with an open-drain output sinking up to 1 A lets the codec trigger or be triggered by room control, partition sensors and screen lifts.
• USB-C passthrough with 15 W power delivery — One USB-C cable gives a guest laptop the room camera, microphones and speakers plus charging, covering BYOD without a separate switching appliance.
• AES67 in and out over the PoE ports — Eight streams of eight channels inbound and up to four outbound digital streams let the codec join an existing AES67 audio network.
• Nine-camera independent control — Cisco states up to nine cameras can be controlled independently, which covers divisible rooms and lecture capture from a single codec.
• Rack, wall or free-standing mounting — The 16.9 x 2.6 x 9.9 in. chassis fits a credenza, a wall pocket or a standard equipment rack with rack ears.

Typical Applications

• Boardroom — three HDMI 2.0 outputs, four phantom-powered microphone inputs and GPIO control suit a fixed executive room built around customer-specified displays.
• Large conference room — five HDMI inputs and up to five video-over-IP streams cover multi-camera and multi-source front-of-room designs.
• Training room — independent control of up to nine cameras supports presenter and audience coverage in instructional spaces.
• Multi-purpose room — GPIO triggers and 120 W of PoE++ let the codec drive partition sensors, screen lifts and distributed microphones as a divisible room reconfigures.
• All-hands room — an 8K-capable HDMI 1 output and AES67 audio networking match large presentation spaces with house audio already installed.

Technical Specifications

Frequently Asked Questions

What call control platforms does Codec Pro G2 register to?

Wi-Fi 802.11a/b/g/n/ac/ax (Wi-Fi 6 / 6E) on 2.4 GHz and 6 GHz with 2x2 MIMO is present on this radio version. Cisco lists Webex, Microsoft Teams Rooms, Zoom for Cisco Rooms, Cisco Expressway and Cisco Unified Communications Manager v15 SU4 or later, alongside H.323, SIP and WebRTC. Cisco also states the device is MDEP certified for Microsoft Teams Rooms.

How many displays can this codec drive?

Three HDMI 2.0 outputs with CEC 2.0. HDMI 1 reaches 7680 x 4320 at 30 fps and 3840 x 2160 at 60 fps with HDCP 2.3, HDMI 2 reaches 3840 x 2160 at 60 fps with HDCP 2.3, and HDMI 3 reaches 3840 x 2160 at 60 fps.

What microphone options does it support?

Four 48V phantom-powered 3.5 mm Euroblock analog inputs rated to a maximum 18 dBu, embedded audio on five HDMI inputs, one USB-C and one USB-A audio input, and eight PoE / PoE+ / PoE++ Ethernet ports carrying digital microphones or AES67 at eight streams of eight channels.

Does it need separate power supplies for room peripherals?

In most builds, no. Eight IEEE 802.3bt PoE / PoE+ / PoE++ ports share a 120 W total budget for digital microphones, Room Navigators and IP cameras, and a separate multi-gigabit port up to 10 Gb serves IP peripherals.

Can it integrate with a third-party room control system?

The codec provides a 4-pin 3.5 mm Euroblock GPIO port supplying 12V +/-5% at up to 0.7 A with an open-drain output sinking up to 1 A, which is the documented hardware control interface. Cisco does not publish a third-party control-system driver list for this codec, so confirm driver availability with your control-system vendor.

How is it mounted, and what are the dimensions?

Cisco lists wall, rack-ear and free-standing mounting for a chassis measuring 16.9 in. (43.4 cm) wide, 2.6 in. (6.6 cm) high and 9.9 in. (25.2 cm) deep, weighing 6.2 lb (2.8 kg). Cisco publishes no rack-unit figure for the G2 chassis.

What cameras does Cisco document with Codec Pro G2?

Cisco documents the Cisco Quad Camera, the Cisco Room Vision PTZ Camera and the Cisco 4K Desk Camera over USB-A, and states that up to nine cameras can be controlled independently.
