SKAARHOJ Rack Control Duo Panel

SKAARHOJ’s line of hardware based control panels provide integrated control of AJA’s FS family of frame synchronizers. The new Rack Control Duo, developed in partnership with broadcast services provider NEP, supports AJA’s FS-HDR, FS4, FS2, and FS1 devices and is capable of ganging control of multiple FS products and processing channels together, making set-up and on-the-fly adjustments faster and easier for operators and engineers with a single tactile hardware control panel.
 
Ideal for any production environment involving multiple source signals, Rack Control Duo is an intuitive hardware control panel with tactile knobs and buttons to easily perform simultaneous adjustments across multiple AJA frame synchronizers.
 
Operators can also use the panel to recall, and implement presets from previous setups across one or more FS devices. When used in conjunction with FS-HDR real time HDR/WCG converters, RGB color corrections can be performed via Rack Control Duo prior to HDR to SDR or SDR to HDR transforms, harnessing the power of AJA’s FS-HDR.

 

Massive Audio Flexibility

The growth of 5.1 and 7.1 audio has increased the number of audio channels that must be managed in production. The MADI standard provides a convenient way to transport huge numbers of audio channels along a single cable, simplifying the cabling demands for broadcasters, mobile trucks, and production. FS4 supports both fiber and coax MADI input and output.  An internal 277 x 208 mono audio matrix allows you to route 1 to 1, or 1 to many, with full routing of MADI, mixdowns, and all audio coming from SDI, fiber, and AES sources for an incredible amount of audio processing capability in a single box.

FS4 also offers high quality Sample Rate Conversion (SRC) on all audio inputs, which can be bypassed for non-PCM audio.

Closed Captioning Conversion

FS4 supports Closed Captioning and the conversion of Closed Captioning between 2K/HD/SD and 4K/UltraHD formats - including full conversion of CEA-608 and CEA-708 standards. FS4 can preserve Closed Captioning even when converting between formats, removing the need to reinsert Closed Captioning after conversion. 

Active Format Description

Automatically sets Active Format Description information to match the converted signal. This means AFD information does not have to be inserted after conversion and provides accurate information for devices that understand AFD. 

Remote Configuration and Control

FS4 is network ready and supports SNMP monitoring and web-based remote control. Units can be connected to an Ethernet network via the built-in 10/100/1000MB Ethernet port, allowing control and configuration of multiple FS units from a web browser on a connected computer.
