Introduction

GLD is an affordable live sound digital audio mixing system from Allen & Heath. At its low price point and with its intuitive user interface and 'plug n play' connection it provides the perfect upgrade for users of analogue mixers such as the Allen & Heath GL Series, and for small to mid-sized venues, tours and rental companies looking for an affordable yet fully featured and configurable professional digital solution that is easy to learn, operate and maintain.

GLD components

The heart of the system is the GLD-80 Mixer. The DSP is located in the mixer and can process 48 channels x 30 buses x 20 mix outputs plus 8 'RackFX' internal effects devices with dedicated return channels bringing the total number of sources able to feed the mix to 56. The rear panel provides connections for 8 inputs and 10 outputs plus an option slot to fit one of several audio networking cards available from Allen & Heath.

Adding one or more of the available AudioRacks lets you configure systems with up to 40 remote mic inputs in addition to the mixer rear connections. This gives you a distributed audio system with convenient CAT5 digital snake based on the proprietary Allen & Heath dSNAKE protocol. The main I/O (Input/Output) rack is the GLD-AR2412 AudioRack providing 24 mic/line inputs and 12 line outputs. It also features a MONITOR port compatible with the Allen & Heath ME and Aviom® personal mixing systems. The GLD-AR84 AudioRack is an expander I/O remote rack adding an extra 8 mic/line inputs and 4 line outputs. You can add up to two GLD-AR84 racks, one at the GLD-AR2412, the other at the GLD-80 mixer.

Up to 64 GLD inputs and 64 outputs can be assigned to an audio option card fitted to the GLD-80 rear panel I/O Port. The MMO (Mini Multi Out) card provides several output formats – 24 channels of ADAT optical out, two 8 channel iDR links to connect the Allen & Heath iDR-8 or iDR-4 mix processors, or the iDR-Out or iDR-Dout output expander, and also compatible with the HearBus hub, and a 16 channel output compatible with Aviom® A-Net 16 or the Allen & Heath ME personal mixing system running in Aviom mode.

The card uses 56 channels from the port. These are assigned using the I/O / Port Out screen. The port channels map to the MMO sockets as below:

I/O Port options for system linking, expansion, recording and audio networking using one of the option cards available from Allen & Heath. 64 channel bi-directional 48kHz audio.

① Input sockets 24 balanced XLR inputs for microphone and line level sources. The preamps are built into the AR2412 rack and their Gain, Pad and 48V phantom power is remote controlled from the GLD console via the dSNAKE link. The output of the analogue preamps are converted to digital format and transported via dSNAKE to be processed and mixed at the GLD-80 mixer.

The sockets are numbered 1-24. Any input can be patched to any channel using the I/O or Preamp screens. The default is one-to-one mapping of the input sockets 1-24 to channels 1-24.

② Output sockets 12 balanced XLR outputs operating at nominal +4dBu line level. Any GLD signal can be patched to any socket using the console I/O screen. The default Template Shows provide a logical mapping of these sockets to get you started.

③ EXPANDER port CAT5 cable link to connect a GLD-AR84 expander rack to add a further 8 mic/line inputs and 4 XLR line outputs. The GLD system numbers these sockets as Inputs 25-32 and Outputs 13-16. This port can also be used to connect to the Allen & Heath ME personal mixing system.

④ MONITOR port CAT5 cable link to connect to the ME personal mixing system. It is also compatible with Aviom® A-Net 16 when Aviom mode is selected in the I/O / Monitor screen.

⑤ dSNAKE port CAT5 cable link to connect the AR2412 rack to the GLD-80 mixer. This carries the 32 inputs, 16 outputs and the monitor port sends audio to and from the rack as well as control for the preamps and system status.

Maximum CAT5 cable length is 120m (396') depending on cable type.

Note that dSNAKE is not compatible with the iLive ACE connection.

⑥ Fan A low noise fan ensures air movement through the rack to keep the circuits within operating temperature range.

- Ensure good ventilation at the back of the rack. Read the safety instructions printed on the panel and the Safety Sheet packed with the unit.

⑦ Mains power input IEC connector, fuse and power ON/OFF push switch for the built-in universal voltage power supply unit. This accepts worldwide voltages from 100 to 240V AC 50/60Hz. Check that you have received the correct mains lead for your territory.

Secure the cable in place using the plastic P-clip. Use a T20 Torx screwdriver to refit the screw.

① Input sockets 8 balanced XLR inputs for microphone and line level sources. The preamps are built into the AR84 rack and their Gain, Pad and 48V phantom power is remote controlled from the GLD console via the EXPANDER link. The output of the analogue preamps are converted to digital format and transported via a Cat5 cable to be processed and mixed at the GLD-80 mixer.

Any input can be patched to any channel using the I/O or Preamp screens.

The sockets are not numbered. This is because the number depends on where the AR84 is plugged into the GLD system. Write-on blocks are provided for you to label the sockets.

② Output sockets 4 balanced XLR outputs operating at nominal +4dBu line level. Any GLD signal can be patched to any socket using the console I/O screen. The default Template Shows provide a logical mapping of these sockets to get you started.

Connect the AR84 AudioRacks Plug a CAT5 cable into the EXPANDER port of the AR84 and the EXPANDER port of the AR2412 or GLD-80 mixer.

● Always plug the AR84 into an EXPANDER port. Do not plug it into the dSNAKE port even if you are not using an AR2412 main rack.

Plug in the mains power leads supplied with the mixer and racks. Secure the leads by hooking them into the plastic clips. If required the leads can be locked into these clips. Use a T20 Torx (starhead) screwdriver to remove the fixing screw.

To turn on the system Turn on power using the rear panel On/Off switches.

The GLD-80 takes around 40 seconds to boot up. Its screen lights white for a few seconds, then turns black displaying its boot sequence. A while later the Home screen is displayed. At this point the yellow Lnk/Err indicators of connected dSNAKE and EXPANDER ports start to flash steadily showing that the link between the mixer and racks is established. The mixer Audio Sync LOCK indicator lights. Finally, the AudioRack Ready indicators light and you will hear a click as the output socket protection relays switch over.

- If the firmware in a connected AudioRack is not the same version as that in the GLD-80 then the mixer will automatically update the rack firmware during power up. This takes a few seconds. During this time the Lnk/Err indicators on the AudioRack flash at a fast rate. Once updated normal flash rate is restored.

To turn off the system The system must be powered down correctly. Return to the Home screen. To do this turn off any active Sel key whilst in the Processing view.

Touch the Power Down button. A popup appears. Confirm the action then turn the mixer and racks off using their power switches.

- If the system is not powered down correctly there is a possibility recent changes may be lost.

- If the system was not powered down as described above then a 'Not shut down correctly' screen appears the next time the system is turned on.

GLD Remote iPad app and wireless router

GLD firmware Version 1.1 onwards supports the GLD Remote iPad app for wireless control of mixing and processing using one or more iPads. This allows simultaneous control of different functions by more than one engineer. For example, one engineer controlling the FOH mix at the GLD surface and another controlling monitors on stage using an iPad.

The router:

• Good wireless range
• Dual band (2.4 and 5GHz)
- Auto channel select
- Adjustable antennas
- Good security

Get the app Download the GLD Remote app from the Apple Store. You can open it in Demo mode without a GLD connected to get a feel for how it operates and to read the ? Help Manual within the app.

Choose a router (wireless access point) GLD Remote is a professional mixing tool that justifies network equipment of suitably high performance, quality and reliability.

For best performance we recommend you choose a dual band wireless router with auto channel selection. Use the more recent 5GHz band in places where there is intense WiFi activity or interference in the more crowded 2.4GHz band. A wireless router with auto channel selection automatically sets itself to an available or least congested channel when you power it up.

Refer to the Allen & Heath web site for more information on choosing wireless routers for use with the Allen & Heath iLive and GLD systems.

Recommended settings:

GLD (default)

Static IP = 192.168.1.50

Subnet Mask = 255.255.255.0

Router

Router IP = 192.168.1.254

Subnet Mask = 255.255.255.0

DHCP 192.168.1.100 to 200

Security = WPA

Set up the router You will need to connect it to a PC using a wired LAN connection. Follow the instructions provided by the wireless router manufacturer to access its setup menus.

Set the router IP address - This must be compatible with the GLD console which has a default static IP address = 192.168.1.50 and Subnet Mask = 255.255.255.0. Go to the Setup / Config / Network screen to check the current GLD settings.

To work with the GLD you must give your wireless router a unique but compatible IP address. Some routers may have a default address that is not compatible and must be changed, for example 192.168.2.1. Some may already be compatible, for example 192.168.1.254.

Set the router DHCP settings - Make sure the router is set for DHCP so that it automatically allocates a compatible IP address to your iPad. To avoid conflict with the GLD static address we recommend you set a router DHCP address allocation range of 192.168.1.100 to 200.

Note You do not need to change the GLD setting to DHCP. The console will work fine with a static IP address as long as it is not within the router DHCP address range.

Set the router security -To prevent other people accessing your Wi-Fi we recommend you enable WPA/WPA2 encryption during router setup. A wireless key (password) will need to be set up.

Make a note of the router SSID. This is the name that the router broadcasts to help identify it in the network list you will see in the iPad Settings Wi-Fi page. If you want you can change the SSID to help you identify it alongside other wireless networks in the area.

After setup, the wireless router can be connected to the Network socket on the rear of the GLD console using a CAT 5 cable. Plug this into one of the LAN (not Internet) ports on the rear of the router.

Position the router Make sure it is within the specified range and in line of sight of the iPad where possible. It can help to place it high up to avoid obstacles such as people and equipment. Avoid locating it behind pillars or walls, near metal beams or on top of loudspeakers.

Recall a 'Template Show' as a starting point

The GLD has a fully configurable audio architecture, control layout and socket patching letting you customise the way you work. It would be a daunting task for the new user if we gave them a 'blank canvas' to start from scratch. Instead we have provided a set of 'Template' Show memories which give you a choice of classic console format to load in as a quick starting point. These present the familiar architecture and logical layout of well equipped analogue consoles.

Once you are comfortable working with GLD you can make changes to your set up and save these as your own 'User' Shows. These let you archive and recall the complete configuration and setup. Use Scenes for instant store and recall of band sound checks, theatre cues and different event settings. Scenes are stored within the Show.

A Show memory stores the complete GLD setup. This includes:

• Current settings
• Mix configuration
• User preferences
  • All Scene memories
• All Libraries

A default show is already loaded when the GLD is shipped from the factory. This is Template1 LR. You can load a different Template as your starting point if you wish:

To load a Template Show Go to the Setup / Memory / Show Manager screen. Available Shows are listed. These include Template and User Shows.

Touch the Template Show you want to load. Touch Recall. A popup appears for you to confirm the action.

- Recalling a Show overwrites all the system settings including the DSP mix architecture, Surface configuration, current parameters, all the Scene and Library memories. If you want to keep the current settings to be used again in the future then first Store them as a User Show.

The Show Manager screen

There are three Template Shows available. These have the following settings:

• SoftKey assignments are Scene Safe
• SoftKeys 1-8 = DCA mute 1-8
• SoftKey 9 = PAFL Clear All
• SoftKey 10 = FX4 tap tempo (FOH only)
• Scene Confirmation = On
  • Global Direct Out = post-delay, pre-fade, post-mute
  • Monitor Port = ME-1 mode
  • I/O Port out = input socket 1-48
  • PEQ = 20-20kHz, Curve Fill = On
• Auxes are post-PEQ, pre-fade (monitors)
  • FX are post-fade (effects)
  • USB playback assigned to CH47/48
  • USB recording from LR via stereo Matrix1

The Template Show 'Board Reset' Scene Each Template Show provides a Scene called 'Board Reset'. This resets the GLD settings to the starting point default for the loaded Template Show. The Board Reset Scene is available in position 1 and duplicated in position 500 for backup.

Use this Scene to instantly reset parameters without affecting the mix configuration, user preferences or the other Scenes. You can edit its Recall Filter to protect parameters you do not wish to reset. For example, you could set the filter to protect the patchbay and master strip assignments in a festival situation.

Note You can also set Scene Safes to protect selected parameters for all Scenes, for example to remove the SoftKeys from Scene recall.

When creating your own User Show from a Template Show you can choose to overwrite the Scene 1 contents with your preferred settings, rename it, write in a description, set its Recall Filter to reset selected parameters, or simply delete it. You can still access the default Board Reset using Scene 500 if needed.

Template1 LR

This Template configures a traditional architecture and layout with stereo LR main mix for mixing FOH and Monitors from FOH:

LR stereo main mix

4 Groups (2 stereo)

8 Auxes (6 mono, 1 stereo)

8 FX (4 assigned to strips)

6 Matrix (2 mono, 2 stereo)

16 DCA / Mute groups

Talkback using mic socket 44

USB playback to CH47/48

Recording from stereo Matrix 1

Template2 LRM (also use for LCR)

This Template configures stereo LR plus Mono bus for working with a 3-way FOH mix.

You can change the type of 3-way Main mix from LR+M (switched bus) to LR+M (mono sum of LR) or LCR using the Setup / Config / Mixer Config screen.

LR + Mono (switched bus) main mix

2 Groups (1 stereo)

8 Auxes (6 mono, 1 stereo)

8 FX (4 assigned to strips)

6 Matrix (2 mono, 2 stereo)

16 DCA / Mute groups

Talkback using mic socket 44

USB playback to CH47/48

Template3 Mon

This Template configures the GLD as a dedicated monitor console with 18 mixes:

6 mono mixes (wedges, fills)

6 stereo mixes (IEM)

Auto switching engineer's Wedge/IEM

8 FX (2 assigned to strips)

Talkback using mic socket 44

USB playback to CH47/48

Recording from stereo Matrix 1

The engineer's IEM/Wedge monitor is configured so that pressing a mono Aux (wedge) mix PAFL key will automatically mute the engineer's stereo IEM monitor. Pressing a stereo Aux (IEM) mix PAFL key will mute the engineer's Wedge monitor.

A few things to know before starting

Before working with the GLD familiarise yourself with its control layout and operating principles.

The Touch Screen

The Home Screen

This screen displays after power up. You can return here by turning off any active strip Sel key while in the screen Processing view. You can also do this by turning on, then off any strip Sel key.

The strip LCD display

The LCD strip above the faders displays information about the channels assigned to the faders. Channels can each be named and have one of 8 backlight colours applied. You can edit these names and colours to easily identify different channel and mix types, or highlight certain instruments and sources.

Select the function of the strip Rotary controls using these keys. The Custom keys are assigned using the Setup / Control / Surface Prefs screen.

- Check that you have selected the correct function when working with the rotary controls.

Press and hold the Alt View key to see the Channel Number, Socket Number or fader dB value in place of the Name in the LCD display.

Choose the Alt View function using the Setup / Control / Surface Prefs screen.

The Fader Banks

There are 2 independent Fader Banks, one with 12 fader strips, the other with 8 fader strips. Each Bank has 4 Layers. This means that the GLD-80 can work with up to 80 fader control strips.

Any strip can be assigned as an Input channel, Mix master, FX send master, FX Return, engineer's Wedge or IEM master, or DCA master in any combination. Strips can be left blank (unassigned). The Template Shows provide a logical assignment of the fader strips to give you a familiar starting point.

To change the fader strip assignment use the Setup / Control / Strip Assignment screen. You can drag-and-drop to quickly reassign the strips.

The Fader Strip keys

4 keys per strip provide quick access to important live mixing functions:

Working with Scenes

GLD has 500 Scene memories. These are 'snapshots' of the live mixing parameters. They store all current mix settings but not the bus configuration and user preferences. Use Scenes to store parameter changes you want to recall instantly, for example cues during a theatre production or sound checked bands during a music show. Use Shows to store and archive the complete GLD setup including its bus configuration, user preferences and all Scene memories.

A Scene stores all parameter settings. A Recall Filter is available for each Scene to let you choose which parameters to recall. For example, work with just the channel fader levels and mutes for a range of Scenes, or change an EQ on one channel using a Scene. You can name Scenes, add a description, copy and paste their settings to other Scenes, delete their contents, and create Cue Lists from selected Scenes arranged in any order and repeated any number of times.

Global Scene Safes can be set to protect selected parameters being overwritten by the Scene system. These can be set using the Scene Safes screen. You can also fully protect a channel or master from Scene recall by pressing the Safes key together its strip Mix key. For example, to protect background music and continuity announcement while a band sound check is recalled.

Refer to the GLD Touch Screen Reference Guide for more information on using Scenes and the other functions accessed via the screen.

GLD lets you set up and work with up to 10 'User Profiles' including an Administrator and 9 Users. You can set permissions and a password to restrict operator access to certain functions.
