FRONT AND BACK PANELS DESCRIPTION ...........................................................................................
1. INTRODUCTION Purchasing LTO VERB, you purchased a very powerful effect processor, easy to use and contained in a very efficient rack package. LTO VERB 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.
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 VERB. VERB offers the possibility to mix Dry and Wet signals digitally or analogically.
b. Power Up Setting After making your connections, turn on the system power using this procedure: Before turning on the VERB 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 VERB and plug the power cord into an AC outlet. Turn on the power of the VERB, pushing the ON/OFF button on the front panel. Turn on the power of the amplifier/mixer, and adjust the volume. 4.
MONO. Set manually the MONO ON/OFF switch to position ON. Connect one audio cable to the INPUT 2 of the VERB from a mono source, and one or two other audio cables from the OUTPUT 1 and OUTPUT 2 of the VERB to a mono/stereo amplification system or one/two mixer inputs.
Sending signal to the VERB is only half of the process. With a mixing console, the output of the VERB 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. Everything is easy if the mixer provides dedicated inputs (called returns) for effect devices like the VERB.
Utility Button(13): To access the UTILITY Menu it's necessary to push the UTILITY Button (13). If the VERB is already working on Utility Menu (Utility LED (4) = ON) each further use of the button will have no effect.
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. All the factory presets do not have digital "%dir" sound, so to permit to use easily VERB as Send/Return device.
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 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. b.
Amp Mod Cyl % Input LP F HP F Var delay line LFO Sin LFO Sin LFO Sin LFO Sin Var delay line Amp Mod Horn % 5.3 Delay Delay effect is a single echo repetition where the repetitions occur after a certain "delay time" and where the number of repetitions depend on a "decay time" time, defining the time necessary to decrease the amplitude of the repetition from the original sound level to zero. Delay- This program provides a delay of up to 1000 ms.
