****** Page 3 ****** Introduction A-Designs Audio Inc. Introduces the VENTURA A-Designs Audio Inc. is proud to produce a new design to professionals in audio recording. We call it the VENTURA. Our goal is to bring a solid state design to market that will integrate with the digital world and at the same time deliver analog warmth with a hint of color and richness to your recordings. Hand-built in the US, the new A-Designs device features three inputs — microphone, instrument and EQ/insert — which may be used together or independently. The product is also equipped with a highly musical three-band parametric EQ and high/low filters, as well as two independent transformer balanced outputs (mic/instrument and EQ). The heart of the VENTURA is its specially designed discrete bipolar transistor operational amplifier that operates on ±30 VDC rails. This new Opamp is a high-gain, fast-slew, stable audio block with virtually no DC offset over the audio spectrum and is capable of driving a 50 ohm load at 50 Hz with very little current draw. It is used in the microphone preamp, instrument input amp and main and EQ and output stages. VenturaTM Owner’s Manual 13
