  • Page 5: Introduction

    LTO CONTROL30 is equipped with two powerful and separate configurable DSP channels, allowing to use up to 30 parametric EQ filters in order to obtain the desired sound and timbre out of the musical signals. CONTROL30 is a versatile and very powerful machine...also don't forget to check our 60 factory presets, they will surprise you...

  • Page 6: Analog Levels

    All connections have been made correctly. The volume controls of the amplifier or mixer are turned down. Insert the Power plug into the POWER input on the rear panel of the CONTROL30 and plug the power cord into an AC outlet.

  • Page 7: Analog

    Standard Use The CONTROL30 may be placed almost anywhere: on a table, on top of an amp, next to a mixing console. If it will be on furniture, check the rubber feet provided to the bottom of the unit. Make sure to place the CONTROL30 away from other audio equipment that may induce fields and away from the signal wiring.

  • Page 8: Mixer

    POWER In the above figure it describes the situation in which you want to apply the CONTROL30 to a couple of chan- nels arriving to a mixing console, in order to apply the desired dynamic process to single instrument's signals;...
  • Page 9 To Load a Preset: Select "Load Preset" using UP/DOWN buttons. Press ENTER button to access the further sub-menu. Select the chosen preset using UP/DOWN buttons. Press ENTER to load the preset or press button if you decide not to load the preset. Once terminated the sequence above, on the display will appear the name of the selected preset and the sys- tem will go back to the main menu.
  • Page 10 This is a digital bypass and the input signal is anyway converted digitally before being sent to the outputs. When the CONTROL30 is in this mode (Bypass LED (5) = ON), all the buttons except the" bypass" button are disabled.

  • Page 11: Preset Functions Description

    5. PRESET FUNCTION DESCRIPTIONS 5.1. EQ Presets a. Flat This program allows the audio signal to cross the CONTROL30 unmodified. b. Bass Debug Bass debug is a program particularly suitable to clean recordings which have an exaggerate bass equalization in the 100 Hz area.

  • Page 12: Brilliant

    d. Brilliant This preset 'moves on' music and gives vitality to 'slow' recordings. The main EQs are centered in the 100 Hz, 1 kHz and 10 kHz area. The boost reaches almost 10 dB in the high end giving more definition to recordings which are poor in high band energy.

  • Page 13: Percussion

    The CONTROL30 makes use of modern digital DSP techniques to recreate this useful filter (the loudness curve improves the listening experience at low volumes and into noisy environments) without analog circuit complexity.

  • Page 14: Soft

    i. Soft What is worse than a beautiful and super dynamic recording mistreated by a too brilliant and harsh mastering and/or equalization? If you thought to certain black/disco music of the '70/'80, you are plain right. This EQ will complement some great recordings by, say, Earth Wind & Fire as if it was tailored on. As a matter of fact, it is.

  • Page 15: Functional Data

    Your ideal sound has lots of punch and impact? Your system is a bit shy on low ends, but otherwise linear? Would you like more 'guts' out of a good pop disc? Try this, it could be the answer. On big systems with high power handling and already well capable in the low end, this kind of reinforcement could be like an earthquake.
