Guramex GVM 1200

12 inputs, 1 M/E

  • 12 inputs (PAL/YUV or SDI)
  • Input modules with analog and digital outputs
  • 4 channel Multiscreen function
  • Super Wipe function

GVM1200 is powerful, intelligently completed, 1 ME production switcher with up to 12 inputs plus 2 inputs for External Key , preview output, program output and 2 auxiliary outputs. Moreover switcher provides loop-through out with analog or SDI converted outputs. With this much production capability, switcher is indented for for mid-size studios as well as OB Vans.

This production switcher is very easy to use .Carefully designed Menu interface and lots of buttons of fast access solve any important functional task in few clicks.

GVM1200 can be easily integrated in systems operating various formats of analogue, digital input and output signals at the time. Frame synchronization at each input provides smooth operation.

A modular structure allows creation of essential configuration, setting up the equipment according to working priorities of an operator or a stage director. Gradual build-up of the switcher is available on the base of capacity of production.

Input modules of GVM1200 are unique, as soon as they have also outputs – both analogue and digital. Existence of output signals from each input module can be useful for use of internal matrix commutator, for monitoring and etc. In number of cases it allows to exclude necessity of converters and distributing -amplifiers . These output signals can be synchronized as from external input signal as well from integrated black burst generator of production switcher.

Along the standard functions GVM1200 provides to its user a function of Multiscreen, independent generator of animated logotypes and 2x channel video storage, also, it has a separate channel of “SUPERWIPE” function, which provides performance of difficult transitions combined with graphics. Audio track recording is available as for video fragments as well for graphic transitions.

One of the main priorities during designing of the video switchers “GURAMEX”, was and still is - insuring of high reliability and durability. Elements base, used for GVM1200 is only from the best producers that supply aerospace and defense industries.

Therefore GVM1200 has 5 years warranty


GVM1200 can provide up to 12 inputs,preview output, program output and 2 AUX outputs. Number of inputs and outputs depends on configuration, selected by a user. Also a user can select which kind of inputs - PAL/YC/YUV or SD/SDI - he would prefer in the configuration. Simultaneous use of digital and analogue inputs and outputs is available as well.

Frame Synchronizers

Production switcher is equipped with frame synchronizers at all inputs that allows mixing of any non-synchronous signals smoothly without interruptions, without use of additional external.

Internal / External synchronization mode

Production switcher can operate in both external/internal synchronization mode. In external synchronization mode the generator is carried out from the input reference signal.


GVM1200 provides wide range of keying:

  • 2 independent channels keying (Chroma Key, Luma Key, Preset Pattern)
  • 2 DSK channels

Also you get a capability of additional adjustment of the keying channel:

  • matching the background to the current fill source of the keying channel
  • defining the rectangular mask for keying signal
  • using spot and mosaic effects

External Key inputs:

2 separate inputs for External Key keep video inputs free and thus increase potential volume of production.

Multiscreen function:

4 channels of Multiscreen function – this is additional source of signal without use of DVE and keying channels.

GVM1200 allows simultaneous overlay on output signal up to 4 scaled windows. Combined image from desired number of windows and background with preliminary installation from menu of options (location, size, border colors and keying).

A separate section of “Multiscreen” is foreseen in order to provide ease use. Up to 8 positions of “Multiscreen” can be stored and set on keys of the given section. Additionally transformation between positions are made with one push on key, smoothly with specified duration.

Animated logotype Generator

Integrated generator of animated logotypes allows recording and displaying of any logotype without using DSK channel.

Internal Video Clip Storage

An internal dual channel independent storage for clips and slides. Up to 50 clips and slides with total duration of 1 minutes can be stored up to each channel, and can be used as TV caption or background.

Super Wipe

Along with standard cut, mix and wipe transitions you can enjoy with your own designed transitions combined with graphic and audio.

Up to 50 graphic transitions can be loaded, total duration of which should not exceed 1 min.

Event Memory

Created to allow each user to save his frequently used switcher configuration, Event Memory memorizes up to 99 states, of which 10 can be assigned to hot recall buttons in “One Touch Section”.

Software Control

Assistant Software Control allows you to control Main Unit and perform any necessary action directly from your PC.
You've got one more ace up your sleeve - GVM1200 Multi Platform! Turn your Android Tab or Smartphone into a Live Production Control Panel. Broadster Multi Platform gives you the freedom and flexibility to manage your work from many popular devices.

Redundant Power Supply

Production switcher is provided with redundant power supplies hot-swappable/hot-pluggable for both control panel and main unit. Power supply status is displayed on the control panel display.

GVM1200 allows to choose the configuration (number and type of production switchers input/output modules) that precisely suits customer needs without wasting money . Modular architecture with distributed processing is provided to guarantee survivability of the system.

All input modules are interchangeable with each other, the same is provided for the output modules. Failure of any module only leads to loss of function or a certain lack of comfort. Damage of any input/output module will not cause the failure of the whole system.

Input Modules

Both analog (PAL/YC/YUV) signal modules and digital signal (SDI) modules can be used.

EXTERNAL KEY Input Modules

Both the module for 2 analog and the module for 2 digital input signals is appropriate.

Output Modules

You can use various type of modules (OUT008xx) for Program, Preview, Auxiliary outputs:

Tally Extension Unit

The main TYLLY output channel, which indicates the sources presented in the image of the program output is included in the Main Unit. Vision mixer allows connect an additional optional Tally extension unit. Tally extension unit allows form additional four signalization channels:

  • program output (PGM);
  • previewoutput (PVW);
  • auxiliary output AUX1;
  • auxiliary output AUX2.
