1. INTRODUCTION Purchasing LTO CONTROL30, you purchase a very powerful equalizer, easy to use and contained in a very efficient single unit rack package. 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...
a. Analog Levels - Analog Input Level Potentiometer (15): The input level control sets the main input gain, before the signal reaches the input bus. It controls both the Input 1 and Input 2 levels simultaneously. - Analog Output Level Potentiometer (16): The output level control sets the level going to the amplifier or mixer from LTO CONTROL30. b. LED and Illuminated Power Switch - Digital Saturation LED (1): Displays the signal level coming into the input during normal operation.
Turn on the power of the CONTROL30, pushing the ON/OFF button on the front panel. Turn on the power of the amplifier/mixer, and adjust the volume. 4.2. Analog a. Levels Setting Proper setting of the input and output levels is crucial in order to achieve the maximum signal-to-noise ratio. It is possible to say that it is usually best to set both input and output level controls at 3/4 or 75% of full.

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 ESC 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 system will go back to the main menu.
To change EQ Type: -Click Util key -Select EQ Setup -Press ENTER to access the sub-menu -Select the EQ Type using UP/DOWN buttons -Press ENTER to confirm -The system asks confirmation of change: press ENTER to go on. At this point the system loads a default FLAT preset of the same type of the selected EQ type. To know what EQ type is currently loaded, click UTIL key, then select the item EQ Type using UP/DOWN keys.
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. This region of the audio spectrum is carefully cleaned and re-balanced by means of a slight boost in the 5 kHz range. The extreme octaves and the central one are left almost untouched. Some modern pop recordings need a similar treatment.
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. The low end is controlled down to 0 dB, while the high end is still slightly boosted. Avoid using this programs with too brilliant or noisy recordings. Try it with modern symphonic music. e. Hi Definition Keyword is 'no compromise'.
The classic 'loudness' filter was once present even in integrated stereo amplifiers, to give more power and definition to sound. With modern day equipments, which need dynamic and linear performance, filters are often not present to shorten the signal path and allow a cleaner electrical structure, but they are analog filters.
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. j. Super Boost A hot loudness program for modern music lovers.
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. Definitely to try with game sound systems, but pay attention to power output and cone resistance. l.
