The M4 is the perfect solution for the modern day studio. Anyone who has used or heard our outboard equipment, will be familiar with its ability to create a warm, smooth, and clean sound that can inject wonderful feelinto your recordings.
Our acclaimed VTC console has also now been accepted as a great sounding must have in the professional recording environment, with many high profile users.

The M4 offers you the quality of our outboard, in a desk that is more compact and affordable than the VTC but still offers you the same great sound.

It has been designed to maximise today's recording techniques, with the addition of an optional ADAT output for easy digital connection to your recording device and software. It makes the perfect front end to any digital recording set up, taking away that clinical, sterile'sound whilst adding warmth and depth to your recordings giving you the sound that you have been longing for.

Everything about the M4 has been designed to give you maximum pleasure, from the unbelievably great sounding 4 band sweepable EQ section, to the numerous valve stages and digital output options. You can be sure that the desk is not only a fantastic piece of engineering, it is also great eye candy!

Available in 16, 24, 32, 40, and 48 channel options, the M4 combines that classic valve sound with modern functionality.
