Special analog design techniques have been used to obtain a precise control of the sound structure down to the minimum details.
The LA-117 “Studio DMI edition” is a multirange analog equalizer especially designed for mastering and mixing
use where very precise settings are required.
For this purpose, the LA-117 is equipped with super fine tuning controls enabling an easy manual recall without the use of step controls.
Inside the LA-117 there are two separate EQs, the first is a Baxandall type and the second is a special 5 band Parametric unit.
The order of the LA-117 Parametric and Baxandall EQs within the signal flow is interchangeable. The interactions between the
two equalizers enable the LA-117 to execute any kind of acoustic correction.
Each parametric band splits the frequency control in two different ranges so that 10 bands can be used.
Moreover, the LA-117 features a “solo” control for parametric eq sections that improves the filter usability.
This feature is not found in any other analog parametric EQ on the market.
The parametric unit is based on a special innovative technology designed by Livio Argentini, different from other parametric equalizers on the market.
The LA-117 uses a parallel configuration that produces very low distortion, low noise end extremely low phase rotation.
The extremely large bandwidth ( more than 300 KHz ) provides a very fast transient response and an extraordinarily natural sound unrivalled in the market.
The very linear ( instrumental type ) electronic balanced amplifier, without transformers or
servo-amplifiers, allows for a perfect square wave response and absolutely no timbric alteration in the sound.
Double gold plated contact connectors.
Many critical components, like potentiometers, are duplicated and connected in parallel to assure long life, maximum reliability and precision.
Switching is made by gold contacts and sealed relays.
The LA-117 use short actuator toggle switches to avoid accidental operation when adiacent knobs are operated.
The special modular construction allows for a quick servicing and an easy customisation.
The insertion of a MID-SIDE matrix, suggested by Luca Pretolesi, and the external insert capability, transform the LA-117 in a complete audio Hub.
