Guramex GVM 2425

Guramex GVM 2425

24 inputs, 2.5 M/E

  • 24 inputs (PAL/YUV or SDI)    or up to 24 HD/SD-SDI inputs
  • Additional 12 Auxiliary outputs
  • 4 channel Multiscreen function
  • Super Wipe function

GVM 2425 is powerful, intelligently completed, 2,5 ME production switcher with up to 24 inputs and 14 outputs. Extra 4 Inputs are primarily for External Key and Extra 4 Outputs are able to process the ME signal. With this much production capability, switcher is indented for use in big live broadcasting studios.

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.

GVM2425 can be 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 GVM 2425 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 GVM2425 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 GVM 2425 is only from the best producers that supply aerospace and defense industries.

Therefore GVM2425 has 5 years warranty.


GVM 2425 can provide maximum 28 inputs and 18 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.

  • Up to 7 signals of main PGM output
  • Up to 5 signals of main PVW output
  • PGM and PVW outputs for ME1 and ME2

GVM2425H is featured with up to 24 HD/SD-SDI inputs with auto detection. Modular architecture allows changing configuration according user priorities - one can choose 12/16/20/24 input assembling for GVM2425H. Dedicated Quad Splits output is represented on each input module. Along with that, GVM2425H has up 8/16 free assignable HD/SD-SDI outputs for PGM, PVW and Auxiliary outputs.

12 Auxiliary outputs

If you need even more outputs an additional AUX output modules can be installed with support up to 12 auxiliary outputs. Each AUX can be assigned for preview outputs of M/E channels, preview outputs of DSK stage, preview output of LOGO generator and «CLEAN FEED» outputs of M/E1 and M/E2 channels.

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 synchronization.

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.


GVM2425 provides wide range of keying:

  • 6 independent channels keying (Chroma Key, Luma Key, Preset Pattern)
  • 4 MSK channels
  • 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:

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

Flexibly assignable Clean Feed output:

Clean Feed signal can be assigned to any output of production switcher.

Multiscreen function:

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

GVM2425 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).
Guramex GVM 2425 Stage

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 20 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.

Guramex GVM 2425 SuperS

Great opportunity to use customized, great looking TV band with the use of SuperWipe function! Create your own creative graphic transitions with audio and store it in to the switchers internal SuperWipe channel.

Guramex GVM 2425 Super Wipe

Up to 50 graphic transitions can be loaded, total duration of which should not exceed 20 min.

Inputs Redirection

Set the input signal you need on the input button you desire without physical rearrangement of cables. If you will need to redirect outputs, you will be able to do it right on the console.

Source mnemonics

In order to let you to maximally focus on your work, weve implemented Source Mnemonic Panel in GVM 2425, which will always show you which signal is coming on each output.

Time Line Function

allows to create sequence of states and transitions, which can be played in automatic or step-by-step mode.

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”.
