BA-31

The BA-31 is a colorful booster preamp that perfectly preserves the authentic sound of the Germanium transistor unit which inspired us to bring this rarity to the modern day.

BA-31 was modeled after a super rare and, of course, super highly sought-after classic. BA-31 is neither clean nor transparent especially when pushed to its limits. The preamp is packed to the top with real analog power, with 40dB of fixed gain, this mic preamp model will add an old-school touch to your recordings while making the best of flexible and easy-to-use modern plugin design. BA-31 is ideally suited to be used as a microphone preamp with both ribbon classics and a range of dynamic mics. The unit also comes in quite handy when DIing guitars. Want to get a nice retro vibe going on your track or sound design project? Just run a group mix through it and enjoy its tasty 1960s crunch.

History.

The original behind our BA-31 was introduced in the 1960s and until the 1970s was to be found in both broadcasting and recording studios across the USA. This rare unit boasts a unique sound somewhat resembling some Neve preamp models. Originally designed as a microphone preamplifier, turntable preamplifier, or booster amplifier its signature vintage color is definitely something you don't come across every day.

Highlights.

∙ True recreation of this rare Germanium transistor preamp sound.

∙ Use with both ribbon or dynamic mics or when DIing guitars.

∙ Give individual instruments or sub-mixes subtle warmth or tasty vintage crunch.

∙ Tame the volume with Gain and Output Trim controls.

My plugins arsenal was poor of preamps; that's the main reason, a part the special price offered, to buy it; it does well with his simplicity; if you find it in promotion I suggest you to buy it with few other Antelope preamps; they do well.
