1 Quick Start Guide 15 If y ou can’t w ait to get started The Alesis Ampliton is a unique product, but its basic hookup and operation is similar to other effects units in most respects. If y ou're experienced with signal processors, this chapter is a "shorthand" guide for those who want to start using the Ampliton right away. If yo[...]

2 Connections 17 Unpacking and Inspection Your Ampliton was packed carefully at the factory. The shipping carton was designed to protect the unit du ring shipping. Please retain this container in the highly unlikely e vent that you need to retu rn the Ampliton for servicing. The shipping carton should contain the following items: • Ampliton with [...]

2 Connections 18 Connecting audio The Ampliton will work in many different applications, whether y ou are connecting an inst rument directly into it, or connecting it through a mixing console. But since the Ampliton is a stereo effect unit, it’s important to know whether the source will be stereo or mono. Mono In, Mono o r Stereo Ou t If you’re[...]

Connections 2 19 Connecting to the Channel Inserts o f a mixing console: Most recording consoles ha ve a jack near the mic and line inputs labeled "Insert". This is typically a TRS jack with the send and retu rn on the same jack. To use the Ampliton as a channel insert, y ou will need an insert cable (not included). This cable splits the [...]

2 Connections 20 Connecting to the Main Ou tputs o f a mixing console: In addition to channel inserts, most mixing consoles have main insert jacks near the main outputs. You can use insert cables to connect the Ampliton to the main L/R bus the same way y ou connect it to a pair of channels. Simply connect one insert cable to the left main insert of[...]

Connections 2 21 Connecting to the inse rts on an instrument amplifie r : The insert send on a guitar or bass amp is usually labeled "effects send and retu rn" or "insert send and return". This allows you to preamplify y ou r instrument before flanging it and sending it to the power amp. Most guitar amps are single channel, so c[...]

2 Connections 22 Connecting to equipment with XLR inpu ts and outputs: If you are connecting the Ampliton to a product with XLR balanced inputs and outputs, y ou will need to convert this signal to a 1/4” unbalanced connector. Make su re that Pin 2 of the XLR connector is connected to the Tip of the 1/4” adapter or cable. Watch out for high lev[...]

Connections 2 23 Using the ModLink The Ampliton can be connected to other effect boxes in the ModFX family via the ModLink. The ModLink is a cable-free connection between two ModFX units that t ransfers digital audio and word clock. The 9-pin male connector on the left side of the unit is the ModLink IN port. The 9-pin female connector on the right[...]

3 Using the Ampliton 25 This section defines t remolo and autopan, and e xplains the functions of the Ampliton’s cont rols in greater detail. The two sides of the Ampliton The basic operation of the Ampliton couldn’t be simpler. It gives y ou access to two different kinds of amplitude-based effects: on the left side is tremolo, which feeds the [...]

3 Using the Ampliton 26 What is Tempo Sync ? Tremolo and Autopan are both rhythmic effects—they have a beat. Sometimes, you’ll want the rate of the effect to match the beat of your music instead of being random. For e xample, you can set the rate so that the Autopan effect pans from side to side once per measure, or once per quarter note. The T[...]

Using the Ampliton 3 27 Description of Controls Rate The [RA TE] knobs change the speed of the Ampliton’s effects: • The [RA TE] knob on the left cont rols how quickly the Tremolo effect will happen. • The [RA TE] knob on the right cont rols ho w quickly the Autopan effect will happen. In normal modulation modes (TEMPO SYNC LED off), tu rning[...]

3 Using the Ampliton 28 Tremolo Mode Rocke r Switch The up/do wn rocker switch beside the Tremolo label on the left side of the unit selects the type of t remolo effect. The LEDs next to the switch light up to indicate the cu rrent mode. There are fou r kinds of Tremolo a vailable, explained below. The rocker switch also selects TEMPO SYNC mode, as[...]

Using the Ampliton 3 29 Patte rn This mode randomly generates a 16-step sequence to modulate the t remolo or autopan and repeats it over and over. Pattern mode sometimes makes the level jump quickly from step to step, while other le vels “glide” from step to step. It sounds somewhat like using “sample and hold” to modulate a VC A on a synth[...]

3 Using the Ampliton 30 Au topan Mode Rocker Switch The up/do wn rocker switch beside the Autopan label on the right side of the unit selects the type of autopan effect. The LEDs next to the switch light up to indicate the cu rrent mode. There are five kinds or shapes of Autopan available. Four of these are similar to the Tremolo modes, e xcept of [...]

Using the Ampliton 3 31 Uncertainty This mode randomly generates a continually altering waveform for the autopan. Patte rn This mode randomly generates a 16-step pattern for the autopan modulation and repeats it o ver and over. Pattern mode sometimes makes the le vel jump quickly from step to step, while other le vels “glide” from step to step.[...]

3 Using the Ampliton 32 Reset Mod Press this button to reset the autopan and tremolo modulation as follows: • In TRIANGLE and SQU ARE modes, press [RESET MOD] to start the wave from the be ginning of its phase. In Autopan, the wave starts at the right side, then moves to the cente r/left. In Tremolo, the wave starts loud, then becomes softe r. ?[...]

Using the Ampliton 3 33 Tap Tempo This button affects the speed of the effect whenever the tremolo and/or autopan is set to TEMPO SYNC mode. In that mode, you can tap this button along with the music to set a new tempo. The Tap Tempo light will flash at the cu r rent tempo. Tap Tempo technique For a reliable tempo setting, make from fou r to eight [...]

3 Using the Ampliton 34 By pass This button sends the signal directly from the input to the output without any effect. Press [BYPASS] to check the sound of the source without any effect from the Ampliton. When the red BYPASS LED is lit, both Tremolo and Autopan are off. The Bypass function can also be activated by the foot switc h. Since the Amplit[...]

4 Sample Settings 35 While there’s nothing like disco vering new sounds for yoursel f, we thought it would be a good idea to pro vide some sample settings of the Ampliton to help get you started. Simply set the knobs on yo ur Ampliton so they’re at the positions sho wn, and press the rocker switches so each effect is in the mode shown by the LE[...]
