3. Processing Screen 3.2 3.1 Input Channel processing pages are accessed by pressing an Input strip Sel key while the Processing screen is selected. The Input Overview page provides a thumbnail view of all processing for the selected input channel. Name and Colour keypad Overview page – Input Channel Input channels, FX sends and returns, Mix masters and DCA masters can each be given a Name and Colour using the on-screen touch keypad.
3.3 Overview page – Mix Channel 3.4 Overview page – FX Send or Return Mix processing pages are accessed by pressing a mix master strip Sel key while the Processing screen is selected. The Mix Overview page provides a thumbnail view of all processing for the selected mix channel. FX processing pages are accessed by pressing an FX Send or Return strip Sel key while the Processing screen is selected. The page provides a thumbnail view of all processing and parameters for the selected FX.
3.5 Channel Libraries 3.6 Libraries let you store and recall presets for individual processing blocks such as EQ and Compressor, and also for the whole Input or Mix channel. Preamp page The Preamp page provides access to the Input Channel source patching, socket Preamp settings, and channel Trim and HPF. Input and Mix channel processing Libraries do not store routing, levels or assignments. The Library window lists available presets.
Note Making a channel Safe using the surface Safe key automatically makes the associated Preamp safe. Turning off Safe using the surface key unsafes the Preamp. Trim on Surface – The surface Preamp rotary adjusts Channel Trim. Consider using this in situations where you are sharing the same Preamp between channels or FOH and Monitor consoles. Trim can provide +/-24dB ‘gain’ control when the source does not have a preamp, for example input from GLD surface RCA line inputs, the I/O Port or USB playback.
3.9 Noise Gate page 3.10 Insert page The Noise Gate automatically attenuates the signal when it drops below its threshold level. For example to: You can insert external equipment or one of the 8 internal FX units into a channel or mix signal path: Reduce excessive ring on a kick or tom drum Reduce hiss on a noisy keyboard when not played.
3.12 GEQ page A 28-band 1/3 octave Graphic Equaliser is provided on each of the 20 mix outputs. It can be adjusted using the touch screen or the surface faders. In - Switch the PEQ in or out of circuit. The curve turns yellow when switched in and grey when switched out. Type - The LF and HF EQ bands may be set as shelving, bell shaped or low/high cut filter response. When set as a filter the response is 12dB/octave.
GEQ Type – Use the drop-down menu to select one of four GEQ types available. These offer different types of cut/boost response: Using the faders to control the GEQ You can quickly access the GEQ on the faders for the mix with its Sel key active by: Touching the screen GEQ Fader Flip button, or Pressing the GEQ Fader Flip key to the right of the faders while in any of the mix Processing pages.
Side Chain Filter - Restricts the frequency range of the signal that triggers the compression. Use this to filter out low or high frequencies outside the range of the wanted signal thus preventing false triggering. Extreme settings can be used for special effect or frequency sensitive compression, for example 'de-essing' to compress just a range of high frequencies to reduce sibilance of a vocal. The default is the filter switched out. 3.
Delay Bypass - Touch the button to toggle the delay in or out. Use this to compare the direct and delayed signal, for example when you are time aligning delay fill speakers. 3.15 Routing Page – Input Channel view The Input Routing page lets you view and adjust the channel sends, routing, assignments and Direct Out. Input Delay Input delay can be used to time align instruments to each other or create extra ‘depth’ on stage.
DIR OUT SRC pull-up window Touch a box to toggle single parameters such as DCA and Group assignments. Touch a box to open the send panel on the right of the screen to adjust multiple parameters such as Aux send levels, assignments and Pre/Post fader settings. The screen Rotary becomes the Aux send level control. Using the GLD fader strips - Press a master strip Mix key. Current settings are shown in the channel strip LCD displays.
3.17 Routing page – DCA Master The DCA master affects the level and mute of an assigned channel back at its fader point. It is another level stage in line with the channel fader. It does not physically move the channel fader. A separate indicator next to the channel Mute key shows if it is muted by one or more DCA groups. GLD provides 16 DCA Groups. These can be used as DCA Groups (level control) or Mute Groups (mute masters).
4. Meters Screen 4.2 FX and Mix Meters pages These pages show meters for all FX and Mixes available. 4.1 Input Meters page Meters for all 48 Input Channels are displayed on this page. Channel Name and Colour is shown below each meter. The Compressor Gain Reduction meter is shown to the right with the Gate Active indicator below it. These show activity in red when switched In, and in grey when switched out of circuit.
4.3 Custom 1-4 Meters pages 4.4 You can assign 4 Custom meter views. RTA The RTA provides a 1/3 octave 'Real Time Analyser' frequency display for the signal currently PAFL signal. These can be viewed in the Home or Meters screens. The RTA can be viewed in the Home or Meters screens. It also displays on the strip meters when GEQ Fader Flip is active. It separates the signal being listened to on the PAFL monitor into 31 frequency bands and shows the relative strength of each as a real time display.
5. FX Screen PEQ – Each FX Return has a 4-band Parametric Equaliser. Touch the PEQ button to open the FX PEQ popup. Touch again to close it. Touch the Param button to choose to adjust the EQ by dragging a curve or changing values using the Rotary. 5.1 The PEQ can also be accessed by pressing Sel on the FX return (IP FX) fader strip. Front Panel view Access the FX using the FX screen or by pressing Sel keys for individual FX Send or Return fader strips. 5.
Chaining FX - FX devices can be routed to each other. For example you could patch the output of a Delay unit into a Reverb, and then return the reverb to the main mix. 5.4 FX Devices available SMR Reverb View Outputs – Touch the View Outputs button to open a window showing where the outputs of the FX device are routed. Each slot can handle up to 8 outputs depending on the device loaded. Most provide 2 outputs (stereo).
In addition there are 5 pages of scrollable ‘Expert’ pages for the Reverb which allow precision control: 2-Tap Delay Page 1 - Reflections - Source Diffusion, Size, Shape, Ref Detail. Dedicated to reflection control. Keep source diffusion and detail low to help intelligibility. Small sizes are not typical for live applications. ‘Shape’ is only available in the Plate model. Page 2 - Echoes - Echo1, Echo1 level, Echo2, Echo2 level. Separate left and right tap delay outputs from a mono’d input.
Gated Verb ADT Doubler An accurate emulation of the classic 80’s Gated Reverb plus two other variants called ‘Panned’ and ‘Powerbox’. The user interface gives instant access to Lo-cut Hi-cut decay spectrum filters and the gate envelope controls - predelay, attack, hold and release. An Automatic Double Tracking module capable of creating short echo/chorusing, classic double tracking and ‘slapback’ tape delay loops.
Speed - Determines the speed of movement across the stereo field. Chorus Preset Name is displayed. Touch and scroll using the screen Rotary for live update. This is a way of live auditioning all library presets for this module (factory, user and USB). You can also select and recall a particular preset using the Library window. Chorus derives from the late 80’s where different stereo field creation techniques influenced the sound of each chorusing unit.
Flanger Preset Name is displayed. Touch and scroll using the screen Rotary for live update. This is a way of live auditioning all library presets for this module (factory, user and USB). You can also select and recall a particular preset using the Library window. MOO 12 Stage Phaser Three classic flanger effect emulations – ‘Ambient’, ‘Vintage’ and ‘Wild’. During research of classic pedal flangers we found numerous LFO modulators and stereo splitting techniques. We implemented them all.
and relies on manual sweeping of the phase chain using the ‘offset’ control. content. Typically a low setting is common to prevent the generated sub bass upper harmonics clashing with the original bass content. Beyond mid position is only useful for Lost Fundamental mode. Offset - Shifts the operating frequency range of the Phaser. Maximum settings force the Phaser to operate in higher frequencies. Lower Offset settings allow lower frequency phase sweeps (more intense).
De-Esser Rotator Based on the flagship iLive FX engine, the De-Esser emulates the classic Auto-Threshold circuit commonly found on high end hardware units. This produces a constant sibilance reduction regardless of signal level, resulting in a more natural De-Essing process. In comparison, threshold based De-Essing produces inconsistent reduction activity which can result in unnatural vocals.
VS1 Vocal Shift Pitch Doubler VocalShift VS1 is a stereo vocal pitch shifter squeezing two channels of high quality pitch shifting into a single effect. It has a very low latency (<6ms), covers the whole vocal frequency range, and minimises the phasing and flutter artefacts common with many pitch shifters. PitchDoubler is a stereo, pitch shifting doubler effect generating the effect of additional voices from its input.
Listen - Touch to momentarily listen to the sidechain filter signal using the PAFL bus. Dynamic EQ SC Config - Left and Right signals are summed to produce a mono sidechain for each band. Choose one of two modes: Cascade - The sidechain for each band is fed from the previous band. Each band is affected by the previous band activity. Parallel - All sidechains are fed from the input to the DynEQ. Avoids band interaction. DynEQ4 is a model of the industry standard stereo 4-band Dynamic Equaliser.
Attack/Release modes - There are two manual and 4 automatic dynamics modes: Transient Controller • Peak Manual • RMS Manual • Auto Punch • Auto Opto • Slow AutoF • Fast AutoF This is an accurate model of the industry standard Transient Signal Processor. Knee - Hard or Soft (easy knee model). Transient Signal Processors provide cut and boost of the attack and sustain envelopes of the input signal. This gives the sound engineer greater control over the transient behaviour of audio programme.
