SOURCE AUDIO Manta Bass Filter overview

  • 1Description

The Soundblox 2 Manta Bass Filter from Source Audio is a pedal intended for electric bass players, and represents the evolution of Source Audio’s Soundblox Pro Bass Envelope Filter. It features 12 filter effects, an additional 12 filters available in extended mode, eight types of distortion, and multiple methods of control—be they internal (envelope followers, LFOs), or external (MIDI, Expression pedals, and Source Audio’s patented Hot Hand brand of control).

A set of control knobs enable adjustments over various onboard parameters—for instance, Depth, Speed, Modulation Source, and Effect Type. An Option Select button allows you to choose among six different effect characteristics, so you can control the level of distortion, the kind of distortion, the dry/wet mix, and more with one knob.

On the modulation source side, you can blend between different LFO waveforms, so your modulation signal can have aspects of square and sine waves. Two footswitches are provided for storing presets, engaging them, or bypassing them altogether. The pedal includes a DC power supply. For an in-depth look at the stompbox’s controls and effects, please see the feature section.

Key Features at a Glance
Up to 24 different Low Pass, Single Peak, Multi-Peak, and Phaser effects.

Access to control parameters typically found on only rackmount systems.

Add a variety of gain and distortions to any of the Manta’s effects for an added boost and flavor.

Proprietary 56-bit Digital Signal Processor and industry-standard 24-bit converters.

A compact, rugged, cast-aluminum housing.

Select either analog buffered or relay-based True Bypass.

Easy-to-program user presets recallable via two footswitches.

A multi-purpose control input for use with Hot Hand, the Source Audio Dual Expression Pedal, or send and receive MIDI.

Controls Explained
EFFECT Knob: The Effect knob selects which effect type will be used.

OPTION Knob: The Option knob controls six different parameters, each selected by the Option Select button.

OPTION SELECT BUTTON: This selects between six different parameters which will be processed by the Option knob. Frequency adjusts the center point of the filter’s modulation range. Resonance adjusts the width of various peaks and notches in the selected filter’s frequency response. Mix adjusts how much dry signal is introduced into the overall sound (turn clockwise for the introduction of clean tone, and turn counterclockwise for the introduction of signal with “LoRetain”—a clean sound that has been processed with a high-cut filter to preserve low end). Volume controls the overall output level, while Drive introduces and adjusts a level of harmonic distortion applied to processed signal. Type rotates through eight different types of distortion, including Soft Clip, Fold, and more.

DEPTH Knob: The Depth knob adjusts the range and direction in which the signal is modulated.

SPEED Knob: Depending on the modulation source, the Speed knob controls either the rate of the LFO, the attack and decay times of the envelope followers, or the “Smoothing” of the Hot Hand.

MOD SOURCE Knob: When Hot Hand, MIDI, or an expression pedal are not being used, the Manta features 5 different types of modulation control: Slow Attack Envelope Follower, Sine Wave LFO, Square Wave LFO, Sawtooth Wave LFO, and Fast Attack Envelope Follower. The Mod Source knob controls a gradual blend in between each selection, so setting this knob between two of the modulation graphics will create a sound with features of both modulation forms.

CONTROL INPUT BUTTON: Selects which external controller type will be used.

PRESET SELECT / BYPASS Footswitch: There are two footswitches on the Manta. The left footswitch corresponds to Preset 1, and the right footswitch corresponds to Preset 2. Pressing either of the footswitches will engages the respective preset. Pressing the same footswitch again puts the pedal back into bypass mode. Pressing the other footswitch engages the other preset without going into bypass. The illumination of the LEDs labeled “1” and “2” indicates which preset is currently enabled. While the pedal is in bypass mode both LEDs remain off.

External Control
The Multi-Function input is an intelligent control input that accepts both digital and analog control signals. It replaces the Sensor input on previous Soundblox pedals. The Multi-Function input connects to wired or wireless Hot Hand accessories, the Source Audio Expression Pedal, or the Source Audio Soundblox Hub. With these pedals and this connection, you can control the pedal through MIDI, expression, or Hot Hand control.
Universal Bypass
All Soundblox 2 pedals offer Universal Bypass, which allows you to select between two types of bypass. We recommend that you choose between the Manta's active analog (a.k.a. buffered bypass) and relay-based true bypass (a.k.a. true bypass) based on what is needed in your pedalboard's signal chain. Ideally, the first pedal in a signal chain is a buffered input followed by true bypass in the rest of the signal chain.
