GSi BURN USER'S MANUAL - Pag. 2/16

1. INTRODUCTION

GSi BURN is a digital simulator of the "rotary" effect as that of the famous rotary amplifiers from Leslie mod. 122 and 147
and similar, dedicated to electromagnetic organs and their simulators, but can also be used with modern keyboards as
well as electric guitars, and is also a versatile multi-effects with MIDI control. The presence of a MIDI interface, an
alphanumeric display and a non-volatile memory to save the preset make the BURN a tool that perfectly integrates with
any modern set-up for both live and the studio.

In order to simulate the famous "doppler" effect of the rotary speakers, the BURN takes advantage of a
powerful microprocessor that runs at 6,4 MIPS and processes the digital signal at a 24 bit resolution,
granting a clean sound and a dynamic range of well over 96 dB.

The distortion effect, much desired from musicians all over the world, is obtained by
means of a true vacuum tube and a special circuitry that recreates all the sonic
character of both the preamplifier and the final amplifier of a rotary speaker like the

famous Leslie 122 and Leslie 147.

2. CONTROL PANEL

The control panel of the BURN offers a backlit LCD display that shows all relevant informations about the use and the
editing of the instrument. The data is inserted by means of a rotary encoder and two buttons.

A) LCD display 16 characters on 2 lines. The backlight is turned on in standard usage. It turns off when the LOCK

mode is activated.

B) EXT/ALT Key: to activate the control from an external device connected to the REMOTE jack. The LED lights up

when the EXTERNAL function is activated.

C) EXIT/LOCK: Used to return to the previous page, exit a menu, or to activate the lock function. The LED lights up

when the LOCK mode is activated.

D) EDIT/ENTER Key: to enter the EDIT mode, confirm an action, enter a sub-menu. The LED lights up when you

enter EDIT mode, and blinks when you are about to enter the value of a parameter.

E) Rotary Encoder: To change the preset when you are on the HOME screen or to change the value of the

parameters when you are in EDIT mode.

3. CONNECTION PANEL

All the connections are on the back side of the BURN. Make sure the unit is turned off before connecting any device.
Remember to turn the amplifier on last and always turn them off first in order to prevent damage due to possible electric
"bumps".

1. Power switch. Turn the instrument on only when all the connections are completed.

2. Socket for 12 Volt DC power supply. Use only the supplied power adapter.

3. MIDI input. Connect the cable from the output of a MIDI instrument to control the BURN.

4. MIDI THRU. At this output you will find an exact copy of the incoming data to the MIDI IN.

5. Input for optional remote control. See chapter REMOTE CONTROL for more details.

6. Left audio input. This input is connected to the TUBE OVERDRIVE circuit and to the DSP processor for signal
processing. Connect here the instrument to which you want to apply the sound effects of the BURN.

7. Right audio input. Connect the output of an instrument with stereo outputs to take advantage of the True Stereo
Bypass, or turn the [I /O] RIGHT IN -> PASS THRU to send a copy of the input signal in this jack to the stereo
outputs.

8. Audio left output. Connect this output to the left channel of the amplifier.

9. Right audio output. Connect this output to the right channel of the amplifier.

10. Stereo headset jack to connect any headphones with an impedance of not less than 32 Ohms.

11. Headphones volume. This potentiometer acts only on the headphones and not on the LEFT and RIGHT outputs.

Either "active" instruments (such as keyboards, computer, electromagnetic organs, etc.) and "passive" (like electrified and
electric guitars, bass guitars, electric pianos, etc..) can be connected to the BURN audio input, the important is that the
input signal does not exceed the amplitude allowed by the BURN which is about 3 Vpp (Volt Peak to Peak), equivalent to

1.05 Vrms. Connect the instrument and adjust its volume until the red LED of the CLIP indicator lights up, then slightly
lower the volume of the instrument in order to reserve a threshold and prevent the occurrence of a digital CLIP as much
as possible. The CLIP LED indicates the presence of a signal overload in both the digital input and output paths. The level
of the input signal influences also the amount of tube distortion, if this is active.

To connect an electromagnetic organ to the BURN, such as the famous Hammond B3 or similar, you have to take an
output from the AO28 preamplifier and take it to an acceptable level by using an attenuator circuit similar to the one
shown below. Contact your technician and ask him to build an adapter for you.

4. EXAMPLES OF CONNECTION

4.1. Connection of a Workstation keyboard.

The BURN offers a stereo audio input on two standard 1/4 inch jacks of type TS (Tip - Sleeve) but the signal used by the
processor and by the tube distortion is the left channel for the majority of effects. However, there are two standard
connectors just to allow you to connect keyboards with stereo output and take advantage of the True Stereo Bypass
when, during a performance, you want to use a stereo sound that does not need to be processed by the BURN.

A digital keyboard with MIDI output can be connected to the MIDI input of the BURN in order to control the Rotary speed
of the effects directly using the commands on the keyboard (for example, the modulation wheel, the sustain pedal, or
other controls on the panel). For more details, see Chapter MIDI SETTINGS.

4.2. Connection of an electric guitar.

The BURN is in the form-factor of a stomp-box exactly like all conventional effects for guitar or bass. The Rotary effect
algorithms are simulations of amplifiers that introduce colors and ambience typical of real amplifiers re-amplified for a PA
stage or recorded with microphones, therefore, it should not be connected to additional amplifiers, but with the BURN it
is possible to exclude the cabinet simulations and use the effect on a real amp. Other effects, however, allow you to
simulate static amplifiers in order to play guitars or organs in regular Hi-Fi stereo sets, Studio monitors or Live amps.
Finally, there are other effects such as chorus, phaser, delay, etc. that can be used just like any other stomp-box in an
existing effect chain.
