The Ventura is a new design from A-Designs inspired by the great Quad Eight consoles. Run at optimal levels, its\u2019 signal is clear and ultra transparent, with all the dimensionality, air, and extended bass you expect from high-quality analog. Push it a little harder and the Ventura\u2019s custom-wound, ear-tested transformer responds with a more aggressive sound while still retaining the utmost clarity. To add its own special mojo, it features a 3-band EQ reminiscent of console EQs from the golden age of recording. And even if you\u2019re one of those engineers who religiously avoid using equalization while tracking, you\u2019ll find yourself looking for excuses to use this EQ\u2014especially if you need midrange punch without harshness on guitars or snare. Plus, the Ventura\u2019s EQ can be accessed via its own insert for sweetening tracks during mixdown. The Ventura also has a high-impedance instrument DI built to enhance the performance guitar and bass pickups.
\nThe C12X Discrete Transistor Op AmpThe heart of the Ventura and source of its ultra transparent audio is the C12X, a discrete transistor operational amplifier designed by Carl Johnson. Operating on +\/-30VDC rails, the C12X is a high-gain, fast-slew, stable audio block with virtually no DC offset over the audio spectrum. Plus, it\u2019s capable of driving a 50-ohm load at 50Hz with very little current draw. It\u2019s used in the microphone preamp, instrument input amp, and main output\/EQ output stages. The mic preamp itself is a single-stage, transformer-coupled design with balanced I\/O. It includes phase reverse, -20 dB pad, +48V phantom power with LED indicator, and conductive plastic gain control pot. The preamp section feeds both the EQ section and a preamp output mult simultaneously.
\nTrue Three-Band Parametric EQ<\/p>\n

The Ventura\u2019s three-band parametric equalizer is also a unique design featuring 33 frequencies with three bands of overlapping ranges from 50Hz to 15KHz. Both the frequency selection and the +\/-12 dB boost\/cut controls are stepped for precise, repeatable settings. Each band has a Q switch with three fixed positions: Sharp, Wide, and Narrow. The low and high bands are peak\/dip, but flipping the shelf switch changes their characteristic to shelf type. The shelving switch disables the Q feature on high and low bands only. When in the up position, the high\/low filters insert the fixed 12dB\/octave high- and low-cut filters, which work whether the EQ is in or out. And finally, the equalizer\u2019s input\/insert return provides direct input to the EQ, bypassing both the mic pre and instrument input.
\nGuitar\/Bass Pickup-Friendly D.I.<\/p>\n

Separate from the mic pre, the instrument DI is a single-stage, single-ended, high-impedance preamp that also benefits from the C12X. Designed specifically to counteract the negative effects of guitar\/bass-pickup loading, it includes a front-panel 1\/4 jack and gain pot. This section also feeds the EQ and preamp output mult simultaneously.<\/p>\n

Combining transparency and sonic versatility with the ability to use its three sections independently, the A-Designs Audio Ventura gives you a \u201cdesert island\u201d preamp that will serve any and all recording applications: studio or live sound, rock band or orchestral ensemble.<\/p>\n
