****** Page 4 ****** Introduction A-Designs Audio Inc. Introduces the VENTURASE A-Designs Audio Inc. is proud to produce a new improved design of the Ventura to professionals in audio recording. We call it the VENTURAsE. Our goal is to bring a high quality, high fidelity, 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, this NEW A-Designs’ device features three separate inputs and three separate outputs microphone, instrument and EQ 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 XLR outputs – mic/instrument and The heart of the VENTURAsE is its specially designed discrete bipolar transistor operational amplifier that operates on high voltage rails. This opamp is a high-gain, fast-slew rate, stable audio block with virtually no DC offset over the audio spectrum and is capable of driving a very low load with little current draw. It is used in the microphone preamp, instrument input amp and main and EQ and output stages. VenturasE Page 4
