Actually, Vacuum tube is a glass tube in which there is nothing but vacuum which is used to increase the amplitude or power of a signal.

Before 1960’s vacuum tube or valve amplifier were used everywhere but today replaced by solid state amplifiers.

However, in audio industry everyone is fan of the analog distorted signal that a vacuum tube amplifier produce. SO, it’s widely used as guitar amp even today.

Presonus combined both vacuum tube and solid state amplifier circuitry together to get the vacuum tube’s distortion and precision of solid state amp.

The resulting sound is clear and crunchy which we all love to listen.

XMAX mic preamplifier

The XMAX technology used in the preamp of Presonus Bluetube is amazingly high headroom, low noise, wide dynamic range, and extended frequency response.

The combination of vacuum tube and solid state circuitry makes XMAX one of the best preamp in the world.

The resultant audio you’ll get doesn’t need any post colorization effects as it’s way richer than any ordinary mic preamp used in audio interfaces.

12AX7 vacuum tube gain stage

This dual triode based vacuum tube was widely use in audio industry between 1947 to 1960. But after introducing the solid state amps, the use was limited to guitar amps.

However, listeners liked a much the analog feel it add. SO, Presonus added it to their several products including Bluetube V2. They added a gain stage knob to control the drive in Presonus Bluetube that helps us in controlling the amount of distortion in the input.

When I first joined my condenser mic with this preamp I got amazed of that cool distortion it adds in the signal. The warmth that I was seeking for was realized in the audio.

BUT, if you don’t like the analog distortion and want crystal clear voice then I won’t suggest you this gear.
