Guramex GVM 3625

36 inputs, 2.5 M/E

  • 36 HD/SD-SDI nputs
  • Additional 24 Auxiliary outputs
  • 5 channel Picture in Picture function
  • Super Wipe function

GVM3625 is powerful, intelligently completed, 2,5 ME production switcher with up to 36 inputs and 24 free assignable outputs. 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.

GVM3625 can be integrated in systems operating with various formats of digital input and output signals of standard and high definition. 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 GVM3625 are unique, as soon as they have also Quad Split outputs for displaying input signals on one screen. Along the standard functions GVM3625 provides to its user a function of Picture in Picture, 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 3625 is only from the best producers that supply aerospace and defense industries.

Therefore GVM3625 has 5 years warranty.


GVM3625 is featured with up to 36 HD/SD-SDI inputs with autodetection and frame synchronizer. Modular architecture allows changing configuration according user priorities - one can choose 12/16/20/24/36 input assembling for GVM3625. Dedicated Quad Splits output is represented on each input module. Along with that, GVM3625H has up 8/16/24 free assignable HD/SD-SDI Auxiliary outputs.

24 Auxiliary outputs

Each of additional 24 Auxiliary outputs can be assigned for preview outputs of P/P channels, DSK stage and 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 .

12 Keyers:

GVM3625 provides wide range of keying:

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

Picture in Picture function

5 channels of Picture in Picture function – this is additional source of signal without use of DVE and keying channels.

GVM3625 allows simultaneous overlay on output signal up to 5 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 3625 Stage

A separate section of “Multiscreen” is foreseen in order to provide ease use. Up to 10 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.

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 3625 Stage

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 3625 Stage

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

Multi-Viewer and Quad Spilt outputs

Fully integrated, 3 channel internal solution for the multi-screen image is at your service. Multi-Viewer allows you to display up to 16 video streams on a single screen in different modes.

Guramex GVM 3625 Stage

The output signal has a resolution of 1920x1080 and is displayed via HDMI and HD-SDI output.

Each video stream has its own audiometer, UMD and plenty of other markers.

The source can be any external video signal, as well as master-channel, or any other internally formed signal.

Dedicated Quad Split (QS) output is represented on each input module.

Integrated Waveform Analyzer

Due to built in waveform scope there is an opportunity to display parameters of any video signal source.

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 3625, 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”.
