All user reviews for the Gyraf Audio Gyratec IX-6

6 channel preamp tube DIY.
Modular construction in Europe 3U rack, each channel being removable.
Max gain of 60dB, -24 dB pad.
Phase, Pad and Phantom front, rotator gain potentiometer output level.
Connectors I / O XLR.
Addition of a possible tool jack.

UTILIZATION

As indicated above: phase, and Pad Phantom top front, below rotator gain potentiometer output level of the bottom panel.
Nothing is easier to use.

SOUND QUALITY

It is a tube preamp, input and output transformer, so it colors the sound and that's the goal.
It has a vibrant, incredible punch,
The amplification tubes gives a nice pleasant saturation when rubs its limits.
Bandwidth is mitigated gently in the grave below 50Hz but there is still signal 5Hz!

OVERALL OPINION

I finished the building in January 2014.
This is a project with Eynkel project, and without him I probably would not finish!
How satisfying to use, for recording or live ... and without any glitches.
Changing the diet to modern technology (cutting) with excellent results, notament in terms of dynamics.
Compared with a kit, the advantage is we know it on the fingertips. I think I have well optimized circuit compared to G9 2 channels, but it was not difficult.

SOUND QUALITY

The preamp provides color, and fortunately, this is what is wanted!

OVERALL OPINION

This is a DIY project with Berl (AF members cf).
This is a 6-channel preamp tube with mount push-pull amplification.
The basis of reflection was the Gyraf G9 which is a 2-way initially, it was therefore modified and even improved!
The choice of lamps and input-output transformers takes precedence over sound quality, and changed at will (since it is the DIY).

The rendering is amazing quality, good headroom, a very advanced design on the place of components to optimize the path of the sound signal, Berl experience has been a great help.

I did the design of the facade, and it is a pleasure to use a machine design to her taste

In use, the preamp is super stable, the lamp technology coupled with modern supply (switching) is a success. Sessions several days with 6 channels simultaneously ... nothing flinch!

To conclude: Upscale hands for 6 microphones.
