Can the Voluum be powered by a 9 V 670 mA plug?

Yes, the Sonuus Voluum can be powered by a 9V DC power supply that provides at least 500mA. Since 670mA is more than 500mA, it is acceptable.

  • Page 2: Safety - Read This First

    Do not open any part of the Voluum case other than the battery compartment. There are no user-serviceable parts in the Voluum. Do not expose the Voluum to rain, liquids or moisture of any kind. If this occurs, disconnect the Voluum from your computer, power supply, and from your musical instrument and remove any batteries then allow the unit to dry out completely before using it again.

  • Page 3: Quick Start

    Owner’s Manual Quick start This manual is a comprehensive guide to the Voluum. To start using it as quickly as possible, follow this short guide. Please refer to the rest of the manual for detailed operating instructions. Connect your guitar/bass to the jack of the Voluum.
  • Page 4 As a result, the pedal control on the Voluum won’t get scratchy and will never wear out. Combined with ultra-smooth pedal action with user-adjustable tension, in a rock-solid chassis, the Voluum gives you unrivalled signal level control.
  • Page 5 We recommend that you visit our web site and register your new Voluum. This is required for direct warranty support. Once you have registered, you have access to firmware updates, the Voluum Desktop Editor Software and you can opt to receive updates and news from sonuus: register.sonuus.com...
  • Page 6 What can the Voluum do? Gate/expander In its simplest form a noise gate cuts the signal when its level falls below a set threshold. The Voluum noise gate not only gives you control over the threshold, but also enables fine control over how quickly it reacts and how much the signal should be reduced in level.
  • Page 7 ADSR Limiter The high voltage analogue power rails in the Voluum give great sonic quality, but it means that high output levels can overdrive other effects in your chain. The limiter can be engaged to soft-limit the signal peaks to keep them within the input range of your other effects to avoid nasty clipping distortion.
  • Page 8 Using the Voluum In the rest of this manual, we cover everything you need to know about the Voluum: from how to connect it to your rig, to how to power it and how to delve in and create your own presets.
  • Page 9 You can also connect the Voluum to the effects loop of your amp: connect the output of your guitar to the input of your amp, then connect the “send” of your amp to the Voluum...

  • Page 10: Lock Switch

    . When this switch is in the LOCK locked position, the Voluum is in Preset Select mode and none of the parameters can be edited or saved: the only thing that you can do is change between presets. If you try to make a change when locked, LoC is shown briefly on the numeric display.
  • Page 11 ). This connection is known as a true-bypass connection because in this state none of the Voluum electronics are connected to the signal: this keeps your original guitar/bass signal as pure as possible. (Unless buffered-bypass mode is enabled, see “Custom settings” on page 35, where the Voluum electronics are active, but have minimal effect on your signal.)

  • Page 12: Selecting A Factory Preset

    The factory presets configure the Voluum into a variety of set-ups, from traditional volume to sonuus’ unique pedal-controlled compressor effects. The Voluum has two modes: Preset Select mode and Preset Edit mode. By default, it is in Preset Select mode and the display alternates between the 3-character preset name and the preset number: either F00–F99 for factory presets 0 to 99 or P00–P99 for user presets 0 to 99.

  • Page 16 Owner’s Manual Selecting and changing parameters When you press or move the knob, the Voluum will enter Preset Edit mode. The EFFECT flashing shows which effect is being edited. Successive presses on the knob will EFFECT cycle between editing the parameters for the gate, compressor, , volume and limiter effects.
  • Page 17 The Voluum signal chain does things differently. The limiter is always the last effect in the chain in order to limit the output of the Voluum. But the other effects in the chain can be considered to be in any order—because the effects are all volume-...
  • Page 18 Not all parameters are controllable (it simply doesn’t make sense for some parameters to be controllable), but for those that are, the same control method is used for each. Note that the Voluum allows you to use different control methods for different effects.
  • Page 19 When using the Voluum as a volume pedal effect, the volume meter can be used as a visual i.e., indication of the position of the pedal ( the current volume) before enabling the effect.
  • Page 20 Adjusting the gate The gate effect on the Voluum is a noise gate/expander. A noise gate is used to suppress unwanted noise when the signal falls to a low level. It works by allowing signals that are above the gate threshold to pass through unchanged, but reduces signals that are below the gate threshold.
  • Page 21 Above the knee, a constant gain- reduction (ratio) is applied to the signal level. Note that the shape (sharpness) of the Voluum compressor’s knee varies as the amount of compression is changed.
  • Page 22 The attack parameter (Att) is the time in milliseconds that it takes the compressor to respond to a signal that exceeds the threshold. A fast attack (Att time is small) can compress short transients, Voluum © Copyright 2014 Sonuus Limited...
  • Page 23 In general, the release should be set fast enough to recover in time to process the next transient. The Voluum has an intelligent automatic make-up gain which maintains the subjective loudness of the signal. The aim of the make-up gain is to ensure that the signal loudness is the same with and without compression.

  • Page 26 The trapezoidal waveform is highly configurable: examples of trapezoidal waveforms are shown below. In the Voluum, the shape of the trapezoid is controlled by the parameters ramp up (r.uP) and ramp down (r.dn), referring to the left and right sides of the waveforms shown. One cycle of the trapezoid waveform is represented by 100 time units.

  • Page 30 Owner’s Manual The Voluum lets you do super-smooth volume fades that would be impossible to achieve using a simple volume pedal: enable FAd (set to on) and set a fade time using the tiM parameter. When the footpedal is moved to the toe-down position, the volume will fade from lo to hi. Conversely, when the footpedal is moved to the heel-down position, the volume will fade from hi to lo.

    Warranty The Voluum is supported by a limited warranty for a period of one year from the date of purchase. During this period, any faults due to defective materials or workmanship will be rectified (by repair or replacement) free of charge. A unit under warranty may be replaced with a reconditioned unit.
