  • Page 1 DIMENSION REVERB USER’S GUIDE SA225...
  • Page 2 The Dimension Reverb also features a new compact physical format in addition to many new and useful features designed for easy on-stage use. Like all Soundblox effects pedals, the Soundblox 2 Dimension Reverb is also “Hot Hand Ready”. The Quick Start guide will help you with the basics. For more in-depth in- formation about the Dimension Reverb, move on to the following sections.

  • Page 3: Multi-Function Input

    OVERVIEW DIVERSE SOUND PALETTE 12 unique, rich-sounding reverb effects based on physical spaces and mechanical reverbs. DEEP CONTROL SET Access to Reverb control parameters typically found only on professional rack systems. STATE-OF-THE-ART DSP Our proprietary 56-bit Digital Signal Processor, the SA601, and crystal clear 24-bit converters.

    To power the unit, connect the included DC adapter power supply to the 9V DC jack on the back panel. Note: Using a non-Source Audio supply could damage the unit. Please be very cautious when using 3rd party power supplies.

  • Page 6: Theory Of Operation

    THEORY OF OPERATION For those readers interested in seeing exactly what’s happening inside the Dimension Reverb, figure 1 is a block diagram of the reverb algorithm. The various control knobs are positioned next to the processing steps they control. OUTPUT PRE-DELAY Volume Trim Diffusion...
  • Page 7 Looking at the diagram of the algorithm, the input audio signal comes in initially and goes through a volume control and a diffusion block (con- trolled by DIFFUSE) before entering the pre-delay line. The length of that delay is set with the PRE-DELAY control. The output of that delay is sent into the main reverb loop through the injection mixer.
  • Page 8 • Source Audio Soundblox 2 MIDI Adapter • MULTI-FUNCTION OUT (optional): Use a Source Audio daisy-chain cable to connect this jack to the sensor/multi-function input of another Soundblox pedal. 9V DC: Connect the included 9 Volt DC power supply here.
  • Page 9 CONTROLS: KNOBS EFFECT (not labeled) The effect knob selects which reverb type will be used. There are 12 posi- tions around the knob. For information on the individual settings see the Effect Types section. PLATE 1 E-DOME PLATE 2 ARENA SPRING 1 STAGE SPRING 2...
  • Page 10 TIME TIME This is the primary reverb control. The TIME parameter sets how long the reverb sound will “ring out”. This can also be thought of as a feedback control to set how long the input will circulate through the reverb effect before dying away.
  • Page 11 PRE-DELAY (OUTPUT) Press button to DIFFUSE (RATE) select option BASS (DEPTH) OPTION SELECT PRE-DELAY (green LED): Sets the initial time before the reverb • begins. Pre-delay times vary between 0 and .5 seconds. In ECHO mode delay times vary between 0 and 2.5 seconds. Pre- delay is excellent for creating slapback effects.
  • Page 12 OUTPUT (red LED): Sets the overall output volume of the effect • which is useful for matching the level of the effect vs. the bypass volume. It can also be used to prevent clipping if longer reverb times are used with continuous loud inputs. DIFFUSE (green LED): Adjusts the amount of “spreading”...
  • Page 13 DEPTH (red LED): The second control related to the LFO. The • DEPTH control adjusts the total amount of modulation applied to the reverb. As the depth is turned up, there is a sense that the wet signal is running through a chorus effect. With more depth, pitch shifts on individual echoes may be heard and things get rather unnatural (but what’s wrong with that?).
  • Page 14 TREBLE TREBLE This knob controls the high frequency damping (or roll-off) in the feed- back loop. As the knob is turned down (full counter-clockwise) and more damping is applied, higher frequencies will tend to die out more quickly for a duller sound. Turn the knob fully clockwise for the least amount of damping which will result in more overall treble in the sound.
  • Page 15 CONTROLS: FOOTSWITCHES There are two footswitches on the Dimension Reverb. The left footswitch corresponds to preset 1 and the right footswitch corresponds to preset 2. Pressing either of the footswitches will engage the respective preset. Pressing the same footswitch again will put the effect back into bypass mode.

  • Page 16: Effect Types

    EFFECT TYPES Here are some brief descriptions of the EFFECT knob settings on the Soundblox 2 Dimension Reverb: PLATE 1 E-DOME PLATE 2 ARENA SPRING 1 STAGE SPRING 2 CLUB MODVERB ROOM METAL BOX ECHO ROOM SOUNDS The first five EFFECT choices are intended to represent real acoustical spaces progressing in size from small to enormous.
  • Page 17 PLATE AND SPRING REVERBS Our Plate and Spring effects are simulations of two popular mechanically constructible reverb units. The critical component in a real plate reverb is large plate of sheet metal. Plate reverbs tend to have a high diffusion rate, so for an accurate representation the DIFFUSE knob should be on the high side.

  • Page 18: External Control

    EXTERNAL CONTROL One of the new Core Features of the Soundblox 2 line of effects pedals is the addition of the Multi-Function Input. The Multi-Function input is an intelligent control input that can accept both digital and analog control signals. The Multi-Function input replaces the Sensor Input on previous Soundblox pedals.
  • Page 19 There are four possible settings: OFF (no LED s on): External control is disabled in this mode • EXP: Expression Pedal for use with the SA161 Source Audio Dual • Expression Pedal. By default, the expression pedal will control the TIME parameter.

  • Page 23: Midi Control

    MIDI CONTROL The Dimension Reverb can be controlled via generic MIDI messages. In order to use the MIDI functionality of the unit, it requires a Source Audio Soundblox 2 MIDI Adapter. Please check www.sourceaudio.net for avail- ability. The adapter connects to the Multi-Function input and provides standard MIDI IN and OUT 5-pin DIN connectors.
  • Page 24 USE WITH HOT HAND All Soundblox pedals are compatible with our Hot Hand accessories. Hot Hand units consist of a ring mounted accelerometer that is used to detect motion for controlling effect parameters. On the Dimension Reverb, a Hot Hand unit can be connected to the Multi-Function input. To enable Hot Hand, select the HH mode as the external control option.

  • Page 25: Universal Bypass

    By default, the Soundblox 2 Dimension Reverb is set to use the relay- based true bypass. To switch to buffered bypass press and hold the right footswitch when powering up the pedal.
