A Versatile "Three in One" Design

Microphone Preamplifier
The microphone preamp is a balanced single-stage discrete opamp, transformer coupled design. It includes switches for: phase reverse, -20 dB pad, +48V phantom power with LED indicator and a gain control knob. With the “Input Switch “set to Mic – the signal is fed to both the input of the EQ section/main output and the transformer output mult simultaneously. This gives two separate outputs at one time and is useful in feeding signal to FOH and/or external FX, power amps, etc. Running at normal levels – a very clear and transparent signal with all the detail, air and extended bass you’d expect from a very high quality analog design is obtained. Push it a little harder and the output transformers will respond giving a more colored character while still retaining clarity.

Three Band Parametric EQ
The Ventura features a 3-band modified Quad Eight style Parametric Equalizer featuring 33 frequencies. There are three bands of overlapping ranges from 50Hz to 15KHz. Both the frequency selection and the boost/cut controls are stepped for precise recallable settings. Each band has its own Q switch with three fixed positions of Sharp, Wide and Narrow. The low and high bands are a peak/dip type with switches to change their characteristic to a shelf type. The shelving switches disable the Q feature on high and low bands only. The equalizer’s input/insert return provides direct input to the EQ. This bypasses both the mic-preamp and instrument preamp and allows for independent EQ access making the Ventura very flexible.

Instrument Input Preamplifier
No need for a Direct Box/DI. This is a high-impedance unbalanced preamplifier designed for guitar/bass pickups and keyboards such as vintage synthesizers. Independent from the mic-pre, the instrument preamplifier section uses a single- stage discrete opamp. It includes a front-panel 1/4″ TS Switchcraft input jack and gain pot. With the “Input Switch “set to Instrument - this also feeds both the input to the EQ section/main output and the transformer output mult simultaneously giving two separate outputs at one time. This is very useful in feeding FOH and/or external FX, power amps, etc.

High and Low Pass Filters
The high and low pass filters are a fixed second order 12dB per octave type with the knees at 9kHz and 150Hz. Both filter switches work whether the EQ switch is in or out and are post the EQ which affects the Main/EQ Output only.

Direct Out Mult / Insert Return   The Output Mult allows the Instrument or Microphone signal to be sent to two different places at once. Send a pre-EQ signal to FOH or an effect, i.e. compressor, delay, power amps, etc and also through the EQ to the main output. The Insert Return allows for the use of external Compressors and/or Effects to be directly added back into the signal path through the EQ to the main output. In the studio or on the stage, the A-Designs Audio Ventura is of a “no frills, no compromise” audio philosophy for pure sonic capture and reproduction. Designed by Carl Johnson.
