  • Page 5: Introduction

    1. INTRODUCTION Purchasing ▲LTO βVERB, you purchased a very powerful effect processor, easy to use and contained in a very efficient rack package. ▲LTO βVERB is divided in 9 effects algorithms and for each of them there are several factory presets so to reach totally 64 factory presets that can be used as starting point to create 64 customer's presets storable into 64 available memory locations.
  • Page 6: Analog Levels

    b. 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 Input1 and Input2 levels simultaneously. - Dry/Wet Mix Potentiometer for Analog Dry/Wet Mixing (16): This potentiometer represents one of the most powerful features of βVERB.
  • Page 7: Power Up Setting

    b. Power Up Setting After making your connections, turn on the system power using this procedure: Before turning on the βVERB power, check if: ˙All connections been have 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 βVERB and plug the power cord into an AC outlet.
  • Page 8 ˙ Set manually the MONO ON/OFF switch to position ON. Connect one audio cable to the INPUT 2 of the MONO. βVERB from a mono source, and one or two other audio cables from the OUTPUT 1 and OUTPUT 2 of the βVERB to a mono/stereo amplification system or one/two mixer inputs.
  • Page 9: Operational Overview

    Sending signal to the βVERB is only half of the process. With a mixing console, the output of the βVERB must go back to the mixer and turned up in the mix before to be able to hear it. Depending from the mixer, there are two options for returning the effected signal to the mix: ˙connecting to dedicated aux return inputs, or ˙connecting to channel inputs.
  • Page 10 Utility Button(13): To access the UTILITY Menu it's necessary to push the UTILITY Button (13). If the βVERB is already working on Utility Menu (Utility LED (4) = ON) each further use of the button will have no effect. Using the Utility Menu is possible to access the following functions: Load Preset: this function allows the loading of one of the 128 available presets, where the first 64 presets (1, 64), are factory presets, and the presets from 65 to 128 are the User's configurable presets and all not initia- lized (Empty) at βVERB selling time.
  • Page 11: Algorithms Descriptions

    When Digital Mix ON/OFF is on, the analog mix potentiometer must be positioned on fully Wet. It is possible to save preset including digital direct sound. When recalled, if the Digital Mix ON/OFF function is on, the preset will have the previously chosen "%dir" and "%eff". If the Digital Mix ON/OFF is off, the recalled preset will have only the Wet full percentage.
  • Page 12: Modulations

    5.2 Modulations a. Tremolo Tremolo is an amplitude modulation of the signal. It is useful for adding warmth and life to standing electric piano or guitar's chords. Amplitude Multiplier Modulated bv Ramo / Sin LFO Tremolo- This program provides an amplitude modulation of the input signal and is normally used as "WET" effect without adding direct sound or adding a few percentage of it, so to avoid the direct sound to cover the amplitude modulation.
