OLED Display

Your new Super Pre is equipped with a high quality OLED display which will give you years of

trouble free service. One of the characteristics of OLED screens of all types over time is burn

in. To help maintain and get maximum life from your OLED display, it is advised to always turn

your pre-amp off when not in use. This will help ensure many years of trouble free service.

For best viewing experience from your OLED display, remove protective

shield before using.

Quick Start

The Bergantino Audio Systems’ Super Pre is designed to be incredibly flexible, yet simple to

operate. All controls have a well-defined purpose and are designed to be as intuitive as

possible. These directions will help take you through the basics and give you a good start for

setting up your sound. However, it is highly recommended to read on to learn all the features

of the Super Pre in order to realize all its very useful features and benefits!

1. Plug the Super Pre in:

With the power switch in the OFF position, connect the 9-12VDC or9-12VAC power source to

the Input connector of your preamp.

The minimum current requirement to ensure proper operation is

500ma. More is fine.

2. Plug in your bass:

Using an instrument cable, connect your bass to the Input jack and turn the power switch on. If

you have active tone controls on your bass, turn all of the controls to the middle or flat position

and adjust the volume to the maximum point you would normally use. If you have a passive

bass, turn all tone and volume controls all the way up.

3. Top panel control settings:

When you first turn on the Super Pre the tone controls will be set flat and no Speaker-Files will

be installed. Set the Instrument Gain and Master Volumes at 0 (off).

4. Input level and Master Volume settings:

For proper operation, it is very important to adjust all gain levels properly. To adjust the Input

gain level, first turn the Master volume and Input Gain of the Super Pre all the way down

(CCW). Next, put the volume controls on your instrument at the maximum level you will be

using them at and play your bass like you normally would, including hard dynamic attacks.

Gradually increase the Input Gain control (clockwise) until the OL (overload) indicator just

begins to flash. Once flashing, reduce the Input Gain (CCW) slightly for some additional

headroom before clipping.

If the OL Led doesn’t come on at all with the Input gain turned all the way up, chances are

you’re either using a more traditional, single coil, low output, bass or enjoy playing with a

lighter touch. If this is the case, select Lo Output for Instrument Level in the Extended

Amplifier’s Feature section under Program Mode and readjust input level as explained

above.

Note: Some onboard preamps have internal adjustable gain controls. If you have

active/passive switching capabilities on your bass, it’s best to adjust these gains such that the

passive and active output levels are the same with the tone controls set flat. This will ensure

maximum headroom for you onboard preamp as well as best gain matching of your bass to the

Super Pre’s input stage.

Remember, the purpose of an onboard preamp is to buffer the pickups from long cable

runs and to provide active tone controls for tone shaping, not to increase your overall

output level and volume. That is what your pre amp and amplifier are for!

Once you’ve matched the maximum signal from your bass without overloading the input stage

of the pre-amplifier, increase the Master volume of the Super Pre by turning the Master

volume knob in a clockwise direction to the desired level. You should be hearing your bass

quite well at this point. You should now only use the Master volume now to achieve your

desired sound level.

For clear, undistorted sound, it’s very important not to overdrive the input stage of the

Super Pre. If you increase in level any tone or volume control on your bass after

adjusting the input gain, you should check to make sure the OL indicator isn’t flashing.

Top Panel Controls and Operation

1. Input Gain: Gain control for the Instrument input. Adjust this level to obtain maximum input

gain before any flashing of the OL indicator occurs.

2. OL (overload) Indicator: Indicates the input stage of the Super Pre is being overdriven

when flashing yellow. If an overload condition is indicated, turn the gain knob counterclockwise

to reduce gain until no flashing occurs and adjust Master volume to achieve desired volume.

Also learn more about properly adjusting the Input gain of the Super Pre in the Instrument

Level section of the Program Mode part of this manual.

3. Master (volume): This control adjusts the Master volume of the Super Pre.

4. Clip (indicator): This indicator will flash yellow when the Super Pre senses an overdriven

or clipped signal at its Line output. This is an indication that the preamplifier is being driven

beyond its ability to produce a clean, undistorted output. If you need more clean volume, go to

the Output Level Adjust menu in the program mode and adjust upward for more clean output

volume, if available (up to +6dB).

5. OLED Display: The OLED display serves many functions and displays everything from

basic tone control settings (home screen) to the many levels of software based menu screens

in the Super Pre.

6. Multi-Function Tone Controls

Mem1/BASS Control: This control has multiple functions:

As a Tone Control, turning the control Left or Right from the Home Screen will decrease or

increase the level of the Bass frequencies in 0.5dB increments, from -9dB to +9dB. The level in

dB will be shown above on the OLED display.

The screen below shows an example of one of the Super Pre’s Home Screens.

Pressing and releasing of this knob will recall, if loaded, the scene that is currently stored in

that Mem1 location of the currently loaded Bank. If the memory scene is already loaded while

pressing and releasing this knob, it will return to the Super Pre’s Main Scene.

Mem2/LMID Control: This control has multiple functions:

As a Tone Control, turning the control Left or right from the Home Screen will decrease or

increase the level of the Lo-Mid frequencies in 0.5dB increments, from -9dB to +9dB. The level

in dB will be shown above on the OLED display.

Pressing and releasing of this knob will recall, if loaded, the scene that is currently stored in

that Mem2 location of the currently loaded Bank. If the memory scene is already loaded while

pressing and releasing this knob, it will return to the Super Pre’s Main Scene.

Mem3/HMID Control: This control has multiple functions:

As a Tone Control, turning the control Left or Right from the home screen will decrease or

increase the level of the High-Mid frequencies in 0.5dB increments, from -9dB to +9dB. The

level in dB will be shown above on the OLED display.

Pressing and releasing of this knob will recall, if loaded, the scene that is currently stored in

that Mem3 location of the currently loaded Bank. If the memory scene is already loaded while

pressing and releasing this knob, it will return to the Super Pre’s Main Scene.

The Super Pre’s Main Scene is the default screen for all the banks when a scene is

not loaded. It changes dynamically, in real time whenever a parameter is changed.

Bright/TRBL Control: This control has multiple functions:

As a Tone Control, turning the control Left or Right from the home screen will decrease or

increase the level of the Treble frequencies in 0.5dB increments, from -9dB to +9dB. The level

in dB will be shown above on the OLED display.

When this control is pressed and released, it activates/deactivates the Bright Control. Use this

control to add some sparkle or snap to your final tonal contour and to add or remove edge and

definition. (See Bright Adjust Menu in program mode on how to program the frequency and

gain of this filter)

7. Mute: When Mute is engaged, the red Mute LED will illuminate and the Super Pre’s DI

outputs, headphones and Line output will be muted.

If the Super Pre’s tuner is enabled (factory default), a fully digital chromatic tuner is activated

and displayed on the OLED display.

The first screen indicates no signal detected by the Super Pre’s tuner. The second screen

indicates a properly tuned A1 string.

8. Prog (Program Button): From any Home Screen, press and release the Prog button to

access and sequence thru the Banking menu, Filters menu, VRC compressor menu, Effects

menu, and Effects Blend, Xover and DLPF menu. Press and hold the Prog button for 3

seconds from any Home Screen to enter Program Mode. The green Prog LED will illuminate

(See Program Mode).

Also, to save a scene, while pressing and holding the Prog button, quickly press Mem1,

Mem2, or Mem3 to save a tone scene in that location (See Mem1/Mem2/Mem3 Save in

Extended Amplifier Features).

9. Mem and Bright LED Indicators These Green Led indicators determine if any of the

Memory scenes are engaged and also if the bright filter is engaged.

10. Multi-Function Foot Switches. Use these switches to engage/disengage Memory

Scenes, engage/disengage the Mute function, or to Bank Up or Bank Down to access one of

7 memory banks, A-G.

Rear Panel Controls and Operation

Extended Amplifier Features

Banking Screen

The Banking Screen displays the status of which Memory Bank you’re in along with any

recalled scene. If no saved scene is loaded, it will display “Main Scene”. It also allows you to

scroll thru the 7 Banks and name scenes.

If you desire to name a scene, do so before saving using the HMid and Trbl knobs as

explained below.

Turn the Bass/Mem1 knob to select Bank you want to load scene into

Turn the HMid/Mem3 knob to move curser for naming scene

Turn the Trbl/Bright knob to choose alpha-numeric character

Once you have selected the Bank to store the scene in, and have named it, while pressing and

holding the Prog button, quickly push and release the desired memory location within that

Bank you want to store the scene (Mem1, Mem2, or Mem3). The corresponding green LED

will illuminate once saved.

If you decide to edit or change the name of a scene, an * will appear next to the

current name until the new name is saved along with the scene.
