System Overview

The Digi-Wave communication system allows users to listen and talk to one another wirelessly in a variety of scenarios. A Digi-Wave system consists of at least one transceiver (DLT 400) and various combinations of transceivers and receivers (DLR 400).

The DLT 400 is a two-way transceiver, meaning that it can transmit and receive audio simultaneously.

The DLR 400 is a receiver only. Users of DLR 400 receivers can only hear what is being broadcast by DLT(s); they cannot create any audio. There are two models of DLR: the DLR 400 ALK and the DLR 400 RCH. For information on the differences, see “DLR 400 ALK Differences” on page 4.

For simplicity, throughout the rest of this manual, the DLT 400 may be referred to as a “DLT.” The DLR 400 RCH and DLR 400 ALK as a “DLR” when the behavior of both devices is the same.

Combinations of one or more DLT’s and DLR’s can be used to facilitate different events, depending on what needs to be spoken and what needs to be heard. Examples of scenarios will be covered here.

Typical Scenarios include:

• Guided Tours - with one or more tour guides (2-way), with audience participation (2-way), or without audience participation (1-way)

• Language Interpretation - one or more interpreted languages transmitted to audience (1-way)

• Intercom - with up to six people able to speak simultaneously (2-way)

There are many more scenarios than are covered in this manual, however these would be variations on the ones discussed here.

Backwards Compatibility

The Digi-Wave 400 Series is backward compatible with the 300 series with limited features.

It is not backward compatible with any earlier transceivers or receivers (DLT 100, DLT 100 2.0, DLR 50, DLR 60, and DLR 60 2.0).

The Technology

The Digi-Wave™ system is a digital spread-spectrum (DSS), simultaneous two-way wireless listening system operating in the 2.4 GHz band. Due to it’s frequency-hopping algorithm, it avoids interference and is a very secure method of communication. For a more detailed explanation of how Digi-Wave technology works, please visit our website and download the “Digi-Wave™ Technology White Paper”.

DLR 400 ALK Differences

The DLR 400 ALK uses 2 AAA alkaline batteries rather than a rechargeable battery like the DLR 400 RCH.

The AAA alkaline batteries can be inserted by removing the panel on the back of the device and putting the batteries in place with the correct polarity. When changing batteries, always change both batteries at the same time.

Help Williams AV protect the environment! Please recycle batteries once they are drained.

Other Differences

The DLR 400 ALK allows you to select a group via the up and down arrows on the front of the device. The volume may be adjusted using the vol buttons. There is no menu system otherwise.

The battery and signal strength indicators on the screen work similarly to the DLR 400 RCH, but are located on the far left of the screen.

When discussing DLR Receivers, this manual is usually referring to the DLR 400 RCH.

Before Programming the Digi-Wave™ System

Depending upon the mode chosen, up to six people can talk in a group at any given time. The Master 1 will have ﬁrst priority, Master 2 has second priority and Guest units have third priority. When two or more people are talking in a group, the participants can hear their voices with the DLT transceivers or DLR receivers, but only those with a DLT transceiver have a microphone and can speak.

Modes

The Digi-Wave 400 system has been designed for ease and ﬂexibility. Many of the settings are automatically conﬁgured for common use cases. These use cases are Tour Mode, Intercom Mode, Hearing Assistance Mode and Interpretation Mode.

While the modes are named by their most common usage, select the mode that ﬁts your personal use case best. The mode is a just starting point; advanced settings can be adjusted to ﬁt your situation.

Modes

Tour

Tour mode is best suited when one or two people are leading a large group. The group can be conﬁgured to only listen to the leader(s) of the group, such as on a museum tour. Alternatively, this mode allows people with a transceiver to speak, which may be useful for tours through noisy areas where hearing may be difﬁcult, such as factory tours.

Intercom

Intercom mode is appropriate when a group of up to 6 people all need to talk to and hear one another. It may be used behind the stage to manage a large theater production, or for a security team at a club.

Hearing Assistance

Page 5

Digi-Wave 400 Series Digi-Wave 400 Series

Hearing Assistance mode is appropriate when using the device to amplify spoken communication between users. The Tone Control in Hearing Assistance mode is automatically elevated, allowing the user to hear more clearly. Users with transceivers can be allowed to speak, which may be useful in a classroom setting.

Interpretation

Interpretation mode is best suited when dealing with multiple, simultaneous audio feeds. In normal interpretation mode, an interpreter may be translating a speech given in Spanish into English, a group of interpreters may be translating a speech in English into several languages. Up to 14 languages and the ﬂoor may be broadcast on the Digi-Wave system at one time.

Court

Court mode allows toggling between secured groups, without letting the Guest unit on an unused or incorrect Group. A Guest unit can access up to four pre-selected groups, but nothing else. Although this mode is named Court Mode, this mode can be used whenever a limitation to group selection is needed.

Interpretation Mode: Broadcast Type

When in Interpretation Mode, you will be required to select a broadcast type. The broadcast type helps determine which channel the DLT transceiver will broadcast on.

Floor will broadcast on channel 0. This is intended to be the main audio for the event that is being interpreted.

Interpreter will broadcast on channel 1 - 14 depending on what is available. Each channel is able to be used by a

dedicated interpreter. All interpreter units can hear the Floor on channel 0, and transmit the Interpreter’s voice on channels 1 - 14. At any time, by changing channels, anyone can listen to the Floor on Ch. 0 or any Interpreter on channels 1 - 14. The interpretation is broadcast 1-way in up to 14 languages.

Repeater is used to extend the range of the Digi-Wave 400 system by up to 50%. The repeater will broadcast on one channel, depending on which channel(s) needs to be extended. This mode does not require a person to be speaking or listening to the transceiver.

For more information on additional features of Interpretation Mode, see “Interpretation Mode Features” on page

16.

Speaking Priority

There are 3 levels of priority.

• Master 1 has ﬁrst priority, and also sets up a majority of the settings for the Digi-Wave system. There

can be only one Master 1 unit per group.

• Master 2 has second priority when speaking, but does not declare any settings for the Digi-Wave system, only for their personal device. This is not available in Interpretation mode.

• Guest units have third priority, and can only declare settings for their personal devices.

The Master 1 and Master 2 have the ability to lock out other talkers by holding down the Talk button for three seconds. All system Talk LEDs will continuously ﬂash while other participants are locked out of the Talk feature. The Master 1 can override anyone else talking within the group. Master 2 has talking priority over Guests.

The Master 1 or Master 2 must have their talk button deactivated to allow the Guest units to talk. When 2-6 people are talking in a group, the participants can hear their voices in the DLT transceivers or DLR receivers. DLR receivers can only listen, as they do not have a microphone or talk button. If a Master 1 unit leaves the conversation, the other devices in the group cannot continue the conversation without them. A Master 1 must be present for the Digi-Wave system to be used.

Channels are used in Interpretation mode. Users conﬁgure their device to listen to a certain channel based on what they need to hear. For instance, in Interpretation mode, their may be a channel per language. Users will listen to the channel for the language they speak, and not hear the audio for languages they do not understand.

In a theatre with two showrooms, the Digi-Wave system may have a group for each theater. Each group may have up to 15 channels of audio in use. Each user will need to be assigned the correct group for the theater they are sitting in, as well as the correct channel for the appropriate audio.

Addresses

Addresses are unique numbers given to each Digi-Wave transceiver in a set up. Typically, addresses will be automatically assigned but in some use cases, manual assignment may be necessary. If manually assigning addresses, make sure each address is unique; addresses between 0 and 1023 can be selected. Each of the 1024 addresses is available per group.

DLR receivers do not have addresses.

Selecting Group(s) and Channel(s)

Each set of people who want to talk and/or listen to each other must be in the same group. Up to 4 Groups can operate simultaneously within range of each other. Up to 15 channels can be used simultaneously.

Group numbers and channels are selected via the settings menu. Pressing the up or down button will allow you to manually select the group or channel number.

Proﬁles

Conﬁgurations of settings can be saved to a Proﬁle to be easily reloaded later. A proﬁle may be created on any device and loaded later. Proﬁles are useful when Digi-Wave devices are used in multiple ways, such as being used for both Tours and Hearing Assistance.

General Rules of Operation

The following rules must be followed. Failure to adhere to these rules will result in unpredictable, unsupported operation.

• There must be only one Master 1 per group.

• Master 2 is optional, and there can only be one per group.

• Any other DLT 400 units must be a Guest unit.

• Each DLT transceiver must have its own address and the address cannot be duplicated within a group.

• Each group must be assigned its own group number. Williams AV recommends a maximum of four groups using the system simultaneously within the same area to prevent interference.

• When using four simultaneous groups, group numbers must be sequential. i.e. 11, 12, 13, 14. Any numbers 0-1023 can be used (only 0-99 if DLR 360 or DLT 400 ALK receivers are being used).

The Main Screen

Groups and Channels

Depending on the Mode you select, you will primarily be working with Groups or Channels. Both settings determine who hears the audio, and are very similar in concept.

Groups are used in every mode. A group is a selection of people communicating with one another. For instance, there may be one tour group for a basic tour and another tour group for a VIP tour. Both these groups may be in the same area, but their audio will not overlap since they are in different groups.

Display Settings

The mode will be displayed at the top of the screen, between the signal strength indicator and the battery level indicator.

Depending on your setting selections, the clock, the channel or the group will be displayed in the center of the screen. Channel or Group is determined by your mode. A large or small clock is determined by the Master 1 settings.

To change any of these settings, hold down the menu button. For instructions on conﬁguring the Digi-Wave

Page 6

Digi-Wave 400 Series Digi-Wave 400 Series

system, see “Basic Settings” on page 12.

Signal Strength Indicator

When a Master 1 is available on the group or channel, the signal strength indicator on DLR Receivers and Guests will indicate how strong the signal is.

When a Master 1 is not available OR while the Master 1 is changing settings that may affect other devices, the icon will disappear. Once the Master 1 has been set up, the DLR Receiver and other DLT transceivers should rejoin the group or channel automatically (with some exceptions, such as a Security PIN being set).

Attendee Checking

The number of DLT transceivers currently talking will be displayed in the bottom right corner box. It does not count DLR Receivers because they do not have a talk button.

Priority Indicator

A label indicating Master 1, Master 2 or Guest will appear on the lower left of the screen on the main screen.

If the label is blinking, the device has not had its settings conﬁgured. Enter the menu system to begin conﬁguring the device.

Setting Up the Digi-Wave™ System

Settings of the Digi-Wave system should be selected based on how the system will be used. A Master 1 device will declare a majority of the settings and pass these settings to devices that connect with it. Since the Master 1 automatically sets most settings, there is little to be set up on Guest devices for basic usage of the Digi-Wave system.

For more information on terminology and a general system overview, see “Before Programming the DigiWave™ System” on page 7.

Language

The Digi-Wave menu is available in multiple languages. Select the language you desire for set up.

Initial Setup

When a DLR Receiver or a DLT transceiver is ﬁrst started, some settings will need to be selected before the device can be used. There are three ways to load settings on a Digi-Wave device:

New Settings

To start from the very beginning with your Digi-Wave settings, select New Settings. This will start you at the beginning of the set-up process where you can set Basic Settings (see “Basic Settings” on page 12).

Load Proﬁle

To load an existing proﬁle on the device, select this option and then select the proﬁle to load. You may either load a proﬁle as it is, or adjust the settings once it is loaded (see “Basic Settings” on page 12).

Join Group

If a Master 1 is already leading a Group or Channel, Digi-Wave 400 transceivers and receivers can automatically search for the group and join it. The list of available groups will be in the order the device detects them, which may not be in numerical order.

The group or channel number could also be manually entered from this screen. Settings will be loaded from the Master 1 device, once a connection is established.

If a group or channel is locked by a PIN, the device will prompt for the PIN at this time. The device will be unable to join the group or channel without this PIN.

For interpretation mode, a Master device should not use this feature. They will be unable to select the channel they desire. Please conﬁgure the device using the normal setup menu. Guest units can use the Join Group function normally.

When using this feature to join a group, Addresses will be automatically set. If you need manual addresses, the DLT 400 will need to be set up using a proﬁle or through setting up New Settings.

If the group should not be able to be automatically joined, this feature can be disabled by the Master 1 device for speciﬁc groups. See “Allow Join Group” on page 15 for more information.

Changing Settings

If settings need to be adjusted later, the menu system can be reentered at any time by holding down the menu button for a few seconds. From there, settings can be edited by selecting New Settings. You may also load a proﬁle or join a group or channel.

The menu system can be exited at any time by holding the menu button. Any uncustomized settings will be set to their default.

To go back to a previous setting while in setup mode, press the Power button.

Basic Settings

Always start setting the Digi-Wave settings with the DLT transceiver that will be the Master 1. Other devices can gather their settings from the Master 1 device to ease setup. DLR Receivers and other DLT transceivers that are not Master 1 may still need their settings adjusted, but they should still be set up after the Master 1.

1. Select a Mode. This determines what other settings may be available. See “Modes” on page 7 for more details on the various modes.

2. Select Speaking Priority. If this is the ﬁrst DLT transceiver you are setting up, you will want to select Master 1. Typically, all other units will be Guest priority. See “Speaking Priority” on page 8 for more details on the various speaking priorities.

3. Select the group number. Holding down the up or down button will seek for available groups/channels. Pressing the up or down button will allow you to manually select the group or channel number. For more information on groups, see “Groups and Channels” on page 8.

4. If in Interpretation Mode, set the Broadcast Type (see “Advanced Settings” on page 12).

5. The Master 1 can select a handful of options that will affect the main display on other devices:

• Select whether to display clock or hide it entirely.

• Select the clocks location, if displayed.

• Select whether the clock is a 24-hour or 12-hour clock.

• Set Master 1 manual address. (Guests and other device can set the address under Advanced Settings.) Automatic address selection is recommended unless there is a need to override the address.

6. Enter Advanced Settings (See “Advanced Settings” on page 12) if more customization is needed, otherwise the device is ready to be used.

Advanced Settings

Advanced Settings are usually available regardless of the mode selected, but some Advanced Settings may be missing from certain modes, or with certain conﬁgurations.

Example - Tour System

The system has been conﬁgured so that up to four people can have open microphones and be talking at the same time. One DLT is set up as a Master 1 unit for the tour guide. Each tour member has a DLT transceiver set up

as a Guest unit.

When a 5th person desires to speak, they push their talk button. This deactivates the talk button of the ﬁrst Guest that turned their microphone on. This First-In-First-Out speaking priority continues each time a member pushes their talk button who is not a part of the speaking group.

If the group speaking needs the 5th person to be able to speak, they can adjust their device settings to allow 5 speakers.

The Master 1 or Master 2 Tour Guide has the ability to take control of the discussion by overriding Guest units, if needed. This is accomplished by pushing-and-holding their talk button down for a few seconds which mutes all Guest unit microphones. When overriding, the talk button will blink red.

A second Tour Guide may be added as a Master 2 unit, which takes priority over Guest units. Master 1 and 2 units have two-way communication capability; they can talk/listen simultaneously to one another.

Example - Intercom

One DLT transceiver is set up as a Master 1 unit. All other DLT transceivers are programmed as a Guest unit. Up to six people can have open microphones and be talking at the same time. When a 7th person desires to speak, they push their talk button. This deactivates the talk button of the ﬁrst Guest that turned their mic on. This First-In-First-Out order continues each time a member pushes their Talk button who is not a part of the speaking group.

Number of Microphones (DLT 400 only)

In modes where multiple speakers are available, the number of speakers at one time can be limited. The maximum number of speakers is 6, the minimum is 2 when this option is available. The number of microphones is not limited by the selected mode (except for in Interpretation Mode, which assumes one speaker per channel). Users with DLR Receivers do not have microphones or talk buttons and cannot be speakers in any circumstance.

Only 4 speakers using DLT 300 transceivers are allowed. 6 speakers can still be in the group, but the 5th and 6th speakers must be using DLT 400 transceivers.

Talk Mode: Push-to-Talk and Push-n-Latch (DLT Master 2 and Guest Only)

On a DLT transceiver, the Master 2 or Guest Talk Mode can be changed to Push and Latch or Push to Talk. Master 1 DLT transceivers are always set to Push-N-Latch mode. This feature is not available on a DLR Receiver as it does not have a microphone or talk button.

In Push-n-Latch mode, when the talk button is pressed and released, it stays in talk mode until the talk button is pressed and released again.

In Push-to-Talk mode (the default mode), the talk button must be held down while speaking, and when released, it shuts off.

Tone Control

The default for tone control is 5, unless in Hearing Assistance mode, where the default is 9.

Using the up and down arrow buttons, adjust the tone up or down to your preference. The number range indicates:

• 1 = Most bass response

• 5 = Flat

• 9 = Most treble response

Side Tone Adjustment

This gives the user the ability to change the volume of their own voice as heard in the headset (side tone). This feature is only available on the DLT transceiver.

Use the up and down arrow buttons to choose between off (0 dB), low (-12 dB), or high (-6 dB).

Encryption PIN:

When a group or channel has been set up with a Encryption PIN, master and guest transceivers and DLR 400 receivers without this Encryption PIN entered cannot listen in on the group. This may be desirable in private or high security-level functions. The PIN cannot be used with DLR 400 ALK units.

The same four digit code must be programmed into all of the Digi-Wave devices in the group. If a different secure code has been entered, participants cannot re-enter the group without reentering the correct secure code. The only time the Encryption PIN is displayed is when it is being entered. As the PIN is being entered, individual numbers will be replaced by the * symbol.

We recommend using a unique PIN to your group. Using PIN 0000 or other easily entered or guessed PIN will not be as effective as a unique pin.

To set the PIN:

1. Select whether or not the connection requires a PIN. If yes, you will be prompted to enter the desired PIN.

2. Choose a 4 digit numerical code; i.e. 4297. You must use the same code on each device in the group.

3. Using the up and down arrows, enter ﬁrst digit of the code (0 – 9).

4. Press the menu/select button to move to the second digit. Enter the next digit and continue until all four digits have been entered.

When setting up the other transceivers or receivers for this group or channel, enter the same code into those devices.

When the Encryption PIN is set, a key icon will show on the main screen under the signal strength indicator.

Microphone Gain, Line Input Gain and Line Output Gain

Gain can be used to increase the volume of the microphone or line input sound. Line input is connected via a USB-C connector.

Use the up and down arrows to adjust the gain to a suitable level. The default value for the microphone gain is

33. The default value for the line input gain is 5. The default value for line output gain is 0, but can be adjusted to +4dB.

Note: For setting up an input line interface, please contact TechBlue Technical Support.

Display Clock

The clock can be displayed in several formats on the main screen. It can be shut Off, displayed Big in the center of the screen, or displayed Small near the bottom of the screen (default behavior).

The group or channel will be displayed at the bottom of the screen in small font if the clock is set to display big. The group or channel will be displayed in the center of the screen if the clock is set to off or small.

Manual Group and Address

If the Group or Address needs to be adjusted, it can be set here. This may be necessary if needed to be backwards compatible with the DLT 300 or DLR 360 from the previous generation.

Encryption

Extra security can be added to the transmitted signal via encryption. The “300 Compatible” 87-bit encryption is default. This level of encryption is backwards compatible with the DLT 300 from the previous generation. The DLR 360 cannot work with encrypted signals.

128 + 87-bit Encryption adds AES-128 encryption on top of the 87-bit encryption. This adds an additional layer of security, but is not backwards compatible and may only be used with Digi-Wave 400 devices. This method requires an Encryption PIN.

To remove an Encryption PIN when using 300 Compatible mode (Pins are required in 128+87 mode):

1. Go through the menu system until you are prompted if you would like to use a PIN code.

2. Select “NO PIN CODE.” The existing PIN will be removed.

Allow Join Group

The Master 1 can prevent other devices from seeing the group as available to join. Disabling Join Group will prevent available groups from being listed under the Join Group menu. Devices will have to be manually set to

the correct group or channel.

See “Join Group” on page 11 for more details on the Join Group feature.

Factory Reset

If the Digi-Wave device is not behaving correctly, or otherwise needs to be reset, a factory reset option is available. This is the last item in the Advanced Settings menu. If the device is reset, all changes selected before this reset will be lost.

The factory reset can also be done manually. A hole is on the back of the device. The hole covers a switch that can only be reached with a paper clip or other thin material. Pressing the button with the paper clip while the device is on will display a prompt on the screen asking to perform a factory reset. Select Yes to reset the device.

Interpretation Mode Features

Interpretation Mode has several features not available in other Digi-Wave modes.

During setup, you will be prompted to select a broadcast mode and select an additional interpretation mode. The available options for broadcast mode are Floor, Interpreter and Repeater. The available options are for the additional interpretation mode are Standard, Bilingual and Relay.

Floor and Interpreter

The ﬂoor is the main speaker or audio of the event. In a lecture, this is the person standing at the podium. Interpreters translate the audio from the ﬂoor into another language. There can only be one ﬂoor in a Digi-Wave system, but there can be up to 14 interpreters.

The ﬂoor will always broadcast their audio on channel 0. Interpreters

can broadcast their audio on channels 1-14. Interpreters can listen to channel 0 as they interpret in standard interpretation mode.

language requires their own DLT transceiver and interpreter. The audience member then listens to the channel for their speciﬁc language.

Note: In previous Digi-Wave versions, this was known as Simultaneous Interpretation Mode.

Repeater Broadcast Mode

Repeater mode can be entered by selecting it as the Broadcast Type during setup.

An additional DLT 400 can be set-up as a repeater to increase the range of each channel.

When repeater mode is used, the Repeater is conﬁgured as the Master 1, and all units sync to this Master Repeater. The ﬂoor unit should be conﬁgured as a guest.

There can only be one repeater per channel and one of the repeaters must be a Master unit. In basic scenarios, it is best to set the Repeater on Channel 1 since most connecting devices can easily access this channel.

Standard Interpretation Mode

Standard interpretation mode allows for each DLT transceiver to listen to the ﬂoor (the main speaker) on channel 0 and broadcast out in one interpreted language on a channel (1-14). Each additional channel or

Bilingual Mode

Bilingual mode allows the interpreter to quickly switch their output channel between Ch. 1 or Ch. 2, depending on which language the audience needs to hear.

This mode eliminates the need for the interpreter to physically switch between 2 DLT transceivers programmed to ﬁxed channels. The interpreter can easily switch between which channel is being broadcast by using the up or down arrow under each channel listed.

For example, the Floor changes from a Japanese speaker to an English speaker. When the Floor is speaking Japanese, the bilingual interpreter selects Ch. 1 as the output channel and interprets Japanese to English to the English audience. When the Floor changes to a English speaker, the interpreter selects Ch. 2 as the output channel and interprets English to Japanese to the Japanese audience.

The DLT transceiver in Bilingual Mode always listens to channel 0, regardless if channel 1 or 2 is chosen as the transmission channel. Only one DLT transceiver can be programmed to transmit on channels 1 and 2.

The bilingual interpretation mode may be utilized within a larger system. For example, one interpreter can use the bilingual mode on channel 1 and 2, while others have the normal mode on other channels. It does not work with Relay Mode.

Relay Mode allows the interpreter to quickly switch between listening to the Floor on Channel 0 or the Relay on Channel 1.

For example, the ﬂoor is speaking Japanese. The Japanese audience can listen to the Floor on Ch.

0. Interpreter 1 pushes the down button to hear the ﬂoor, and interprets Japanese to English to the audience listening on Ch. 1. Interpreter 2 speaks English and Spanish, and cannot translate from the ﬂoor as they do not speak Japanese; they need to listen to Interpreter 1’s translation as a relay. Interpreter 2 listens to the relay (Interpreter 1) by pushing the up button and interprets English to Spanish to the audience listening on Ch. 2.

Channel 1 is automatically the Relay channel. Channel 1 will automatically listen to Channel 0, just as in Standard Interpretation Mode. The DLT transceiver transmitting on Channel 1 cannot switch and listening to Channel 1, and the ﬂoor cannot listen to channel 1. Interpreters on other channels (2-14) are able to switch which channel they are listening to.

Only one DLT can be programmed to transmit on each channel. All interpreter units must be programmed in the Interpretation with Relay Mode, and cannot be combined with units programmed in other modes.

Court Mode

Court mode may require a ﬁrmware update to version 1.2.0 or higher to be available on your Digi-Wave devices.

Court mode is used to limit users to speciﬁc groups. When not in court mode, a guest Digi-Wave unit can change their group to any group. In Court Mode, the guest unit can only access up to four pre-selected groups.

Limiting the access to groups may be useful in situations requiring privacy and security, such as in a court. For example, a lawyer may need to privately consult with their client on Group 12, and may also need to listen to the judge on Group 10. To prevent the lawyer from accidentally broadcasting private case information on any other

CH 2CH 2

Group, the lawyer would be limited to only accessing Groups 10 and 12.

PIN codes can be assigned to a Group to further secure access to a group. Court mode has the added beneﬁt of quickly toggling between groups, even if they require a PIN code, without letting the Guest unit end up on an unused or incorrect Group.

Although this mode is named Court Mode, this mode can be used whenever a limitation to group selection is needed.

Device Availability

Court Mode is only available for DLT 400 transceivers and DLR 400 RCH receivers. It is not available for DLR 400 ALK units or for backwards compatibility with the Digi-Wave 300 Series.

For older Digi-Wave 400 series units, a ﬁrmware update may be required to use Court Mode.

Group Selection

A Master unit can only be in one group and cannot toggle between groups. Like most other modes, the Master unit will be programmed with the settings for one speciﬁc group.

Guest units can access up to four groups. The Guest will be able to add up to four groups. If a PIN code has been set up for the group, the Guest will be required to enter it when they add the group. PIN codes are only available in with Encrypted signal transmission.

Both the Master and any Guest devices must be set to either encrypted or unencrypted signal transmission.

Once the setting for Court Mode have been saved on a Guest device, any Group previously accessible by the unit will be erased from the device. All groups the Guest unit should be allowed access to will need to be entered at once. A single group cannot be added or removed later.

Toggling Between Groups

Once setup is complete, the Guest unit can use the Up and Down buttons to toggle between the list of groups on the left hand side of the screen.

The Guest indicator will ﬂash until the group is joined. If a device seems unable to join a group, check the PIN code.

Locking the Device

To prevent Guest units from accessing the setup menu, using Basic Lock is recommended. Basic lock can be activated by holding the volume up button and menu button at the same time for a few seconds.

Guest units can still edit some personal auto settings by repeatedly pressing (not holding) the menu button. These settings include viewing the System Information, and Adjusting Mic Gain, Side tone, and Tone. Volume is adjustable using the volume up and volume down buttons.

Microphone Mute

Court mode requires Push-n-Latch mode. Push-to-Talk mode is not available in Court mode. To mute your microphone, press the Talk button so the red light around the Talk button is no longer on.

Holding down the talk button will not mute all speakers in court mode.

Saving and Replacing Proﬁles

After settings have been conﬁgured, you will have the option to save your settings as a proﬁle, or replace an existing proﬁle. This is only available if Advanced Settings have been adjusted.

If you choose to not save your proﬁle, the device will still use the settings but they cannot be loaded again if the settings are later changed.

Saving Proﬁles

After selecting your settings, you can select a numbered proﬁle where you can save your settings. Five proﬁles are available.

Proﬁles that are being used have a disc icon next to them. Proﬁles can be overwritten if desired.

Select the proﬁle name to use to save the settings to the proﬁle. If the proﬁle is already in use, conﬁrm that you are replacing an existing proﬁle.

Loading Proﬁles

For information on loading proﬁles, see “Load Proﬁle” on page 11.

Advanced Interpretation Module

The Advanced Interpretation Module (AIM) introduces the following new features to a Digi-Wave® system:

• Q&A Mode

• 24-Channel Interpretation Mode

• Control Function

• Channel Naming

• Channel Sub-Groups

Advanced Interpretation Module (AIM) Features are only available for the DLT 400-AIM variant of the DLT 400 transceiver. To check if your DLT is the AIM variant, check if the word “AIM” is present under the battery symbol on the display. Contact your local Williams AV representative regarding possible upgrade paths to the DLT 400AIM variant.

Compatibility

• DLR 400 RCH units on ﬁrmware version 1.3.0 or higher are compatible. Contact your Williams AV representative to upgrade your ﬁrmware.

• DLR 400 ALK units are not compatible with the special AIM features.

Interpretation Q&A Mode

Interpretation Q&A Mode is used to facilitate Questions and Answers between the audience and a presenter in a bilingual setting. Q&A Mode can also be utilized in bilingual meetings and two-way tours since two open mics for each language are available. This enables a ﬂuent and natural interchange of opinions and commentary across language barriers. Interpretation Q&A Mode is limited to two active languages.

Devices Required for Q&A Mode:

Scenarios for Q&A Mode

1. Scenario 1: Presentation with Interpreted Audience Questions

The interpreter listens to CH01 and CH02 consecutively and can speak to the presenter on CH01 and interpret what they hear to the audience on CH02 or the interpreter is listening to the audience on CH02 and interpreting what they hear to the presenter on CH01:

2. Scenario 2: Bilingual Meetings with Multiple Participants

Two speakers from both sides (CH01 and CH02) can simultaneously speak and the interpreter is interpreting to CH01 on CH02. (Note a maximum of two people per channel can speak at once and the Interpreter can always speak).

3. Scenario 3: Bilingual Two-Way Tours

The interpreter listens to CH01 and CH02 simultaneously and can speak to the presenter on CH01 and interpret what they hear to the audience on CH02. When the interpreter is listening to the audience on CH02 then they can interpret what they hear to the presenter on CH01.

- You may reprogram the presenter DLT from Channel 01 to Channel 02 – and the audience question DLT from Channel 02 to Channel 01

Scenario 2: Bilingual Meeting with Multiple Participants

Q&A Mode may be used in bilingual settings where multiple participants need to be able to ask questions or participate in a discussion. This mode is useful for meetings where several delegation members in two different languages should be able to have their opinions interpreted into the other language.

Q&A Interpretation mode supports two languages. CH01 is the language of one delegation. CH02 is the language of the other delegation. Two microphones can be active for each language at any one time, enabling two delegates to speak seamlessly at the same time while the interpreter interprets into the other language.

The interpreter will listen to the audio feed from both CH01 and CH02 simultaneously. The interpreter will toggle their output between CH01 and CH02 depending on which language they are currently interpreting into. When interpreting from delegation 1 (CH01) language into delegation 2 (CH02) languages, output CH02 will be active on the interpreter DLT. When interpreting from the delegation 2 (CH02) languages into the delegation 1 (CH01) language, output CH01 will be active on the interpreter DLT.

2. MODE: Q&A INTP

6. Use the arrow up button to go to CH 02 for the interpreted language. Some DLRs may be programmed to listen to the presenter language on CH01 for assistive listening or other purposes.

What to do if the presenter language switches:

There is no need to reprogram the interpreter DLT or audience DLRs if the presenter languages switches. If channel 01 originally represents English and channel 02 represents Spanish for example, these channel numbers will continue to represent the same languages after a presenter language switch. There are several ways to handle presenter and audience question DLTs.

- You may switch the DLT for the presenter with the DLT for audience questions.

- You may assign a presenter DLT to channel 01 and another presenter DLT to channel 02 and give presenters in different languages different DLT units. The DLTs may easily be identiﬁed by different color silicon skins (optional accessory CCS 061 BK, GR, RD or BL). In a similar manner, you may have two different DLTs for

3. MASTER/GUEST: Master 1. This selection is usually recommended for the interpreter. Every Q&A system requires exactly one Master 1. Master 2 is optional.

7. CLOCK: Set current time if desired. All units in the Q&A system will sync their time to the MASTER 1 unit.

9. Press TALK to turn on the TALK button for the Interpreter unit.

Note: It is possible to program multiple interpreter units for a setting where multiple interpreters take turn interpreting. However, only one interpreter can have their TALK button pressed at the same time. An interpreter unit programmed as MASTER 1 can take over the open mic from an interpreter unit programmed as GUEST. An interpreter unit programmed as a GUEST can’t take over the open mic from an interpreter unit programmed as MASTER 1 until the MASTER 1 unit presses the TALK button to make it inactive.

PROGRAMMING ADDITIONAL DELEGATION UNITS.

Go through the same steps as above for each DLT you would like to program for the delegation. Up to 1024 DLTs can be connected to the overall system. For key members, you can program them as Master 2 units, so that they don’t risk being bumped off if somebody else presses their TALK button. Keep in mind that only two microphones may be active at the same time for each delegation (channel/language) (in addition to the interpreter). If you would like to have a set-up where a new delegate is not allowed to “butt in” and talk before another delegate has turned off their TALK button, then program all delegate DLTs as Master 2 units. Unlimited units can be programmed as Master 2.

3. MASTER/GUEST: MASTER 2.

We recommend programming the DLT for the most important member of the delegation as Master 2. Master 2 is optional, but it enables key delegation members to always have their TALK button on when speaking without risking being bumped off if there are too many open mics in the system. Two open mics are allowed at the same time for each delegation (channel/language) in addition to the interpreter.

4. GROUP #: Choose the same group number as the interpreter.

C. DLR Programming

The following steps are for DLRs to be used as listen only devices. DLRs may be used for example for junior delegation members who need to hear the conversation in one of the languages but are not expected to participate.

1. Enter programming mode by holding the menu/select button for three seconds, choose your programming language.

2. SET UP: JOIN GROUP

3. SELECT GROUP: Choose the same group number as the interpreter.

4. Channel: The DLR will be on channel 01. Participant can choose to listen to delegation 1 or delegation 2 language. Use the arrow up button to go to CH 02 if desired.

Scenario 3: Bilingual Two-Way Tour

Q&A Mode can be utilized in bilingual two-way tours to enable all participants to freely ask questions in their language to be interpreted back to the tour leader.

Q&A Interpretation mode supports two languages. CH01 is the language of the tour leader(s) and possibly some of the tour participants. CH02 is the language of tour participants who require interpretation into another language. Two microphones can be active for each language at any one time, enabling two tour leaders to speak seamlessly at the same time while the interpreter interprets into the other language.

The interpreter will listen to the audio feed from both CH01 and CH02 simultaneously. The interpreter will toggle their output between CH01 and CH02 depending on which language they are currently interpreting in. When interpreting from the tour leader’s language into the tour participant’s target language, output CH02 will be active on the interpreter DLT. When interpreting questions from the tour participants back to the tour leader, output CH01 will be active on the interpreter DLT.

Interpreter output: CH02 Interpreter output: CH01

24-Channel Interpretation Mode

24-channel mode is intended mainly for large interpretation conferences. As the name implies, it allows for 24 channels/languages instead of the ﬂoor + 14 languages supported in standard interpretation mode. One difference compared to Digi-Wave® standard interpretation mode is that the 24-channel mode is a pure one-way mode. This means that an interpreter DLT on one of the channels works as a transmitter only. An interpreter using a DLT can’t hear the ﬂoor language directly through the DLT. Instead, the interpreter would typically use an interpreter console such as the IC-2 to hear the ﬂoor language.

Devices required for 24-channel mode

1. 1 x DLT 400-AIM for Interpreter: Broadcast Type: Interpreter – Master Channel 01

2. 1 or more x DLT 400-AIM for Interpreters languages 02-24: Broadcast Type: Interpreter – Master – Channel 02-24

3. 1 or more x DLR 400 RCH for listen only participants: Channels 01-24

4. Optional: 1 or more x DLT 400-AIM as repeater units: Broadcast Type: Repeater – Guest – Channel 01-24

4. The DLR will be on channel 01. Use the arrow up button to go to channel 02 if desired.

Programming for 24-Channel Interpretation

A. Interpreter DLT Programming

2. MODE: INTP14

3. MASTER/GUEST: MASTER. One (and only one) interpreter DLT has to be set up as MASTER. The other interpreter DLTs have to be set up as GUEST.

4. GROUP #: Choose a group number. All DLTs and DLRs in the INTP24 system need to be connected to the same group.

5. BROADCAST TYPE: INTERPRETER. Repeater units can be added to add range. Max. 1 repeater unit per channel is allowed.

6. CHANNEL: 01. Choose channel 01 for the ﬁrst channel. Additional interpreter DLTs will be on channels 02-

24.

3. SELECT GROUP: Choose the same group number as the interpreter.

The DLR will be on channel 01. Use the arrow up button to go to channel 02-24 if desired. Hold the arrow up button to seek for active channels.

Control Function

A DLT 400-AIM device can be programmed is a CONTROL unit. This enables channel naming and sub-groups to be set up ofﬂine. The control function makes it possible to make changes to a Digi-Wave® system without interrupting an ongoing event. The control unit is synced to the MASTER when convenient, for example during a break. All other DLTs and DLRs (RCH only) then inherit channel names and sub-group information from the master unit. Channel naming and sub-group programming is only available through a DLT programmed as a CONTROL unit.

The DLT 400-AIM functionality enables a CONTROL unit to be set up for all the interpretation modes:

• INTERPRET. (Standard interpretation mode incl. BILINGUAL and RELAY)

• INTP24 (24-channel interpretation mode)

• Q&A INTP (Interpretation with Question & Answer)

DLT 400-AIM does not enable channel naming and sub-groups for other Digi-Wave® modes such as Tour, Hearing Assist, Intercom and Court mode).

See the sections “Channel Naming” and “Sub-Groups” for details on CONTROL unit programming.

7. CLOCK MODE: As desired (12 HOUR or 24 HOUR)

8. CLOCK: Set current time if desired. All units in the system will sync their time to the MASTER unit.

9. ADVANCED SETTINGS: In most cases, there is no need to go into advanced settings. If you choose NO, then the programming is done. For more information on Advanced Settings, reference page 12 of the User Manual for more information.

10. The TALK button will automatically be turned on, the ﬁrst interpreter unit is ready.

ADDITIONAL INTERPRETER DLT UNITS:

Program additional interpreter DLT units in the same manner on channels 02-24 as GUEST units.

B. DLR (Listen Only) Programming

The following steps are for DLRs to be used for the audience to listen to interpreted languages.

1. Enter programming mode by holding the menu/select button for three seconds and choose your programming language.

2. SET UP: JOIN GROUP

Channel Naming

The channel name can be any 3-letter ISO language abbreviation out of 100 common languages; OR custom 5-character names (letters, numbers, blank). Channel naming is done on a DLT programmed is a CONTROL unit. The control unit is synced to the MASTER when convenient. All other DLTs and DLRs (RCH only) then inherit channel names from the master unit. See the document “AIM List of Channel Names” for details on which channel names are available.

Digi-Wave 400 Series Digi-Wave 400 Series

Programming Channel Names

1. Enter programming mode by holding the menu/select button for three seconds, choose your programming language, then select new settings.

2. MODE: INTERPRET, INTP24 or Q&A INTP.

3. Make sure you choose the same mode as the MASTER unit of the Digi-Wave® system. If the modes aren’t the same, then the Control unit will not be able to synchronize with the Master unit.

4. MASTER/GUEST?: CONTROL.

5. GROUP #: Choose the same group number as the MASTER 1 of the system you wish to update.

If you keep 01 as the channel name, then you move to channel name

programming for channel 02.

If you choose ISO CODE,

Then, the next screen is: CH01 REGION: WORLD, EUR/AM, INDIA/SA. Choose region and then 3-letter language code for desired language.

If you choose CUSTOM,

6. SETUP SUBGROUP: NO. Select NO if you don’t wish to set up a subgroup. See the SUBGROUP section for details on setting up subgroups.

7. Select a CH01 NAME: The options include: 01, CUSTOM or ISO CODE. (For standard interpretation mode, you can also program the channel 0 (ﬂoor language) name.)

• Then the next screen is LETTER 1-5: Choose between the letters in the English Alphabet, blank and 0-9. Program 5 letters for Channel 01. (Reminder the power button can be used as a back function for

mistakes.)

8. Once you have programmed the name for Channel 01, then the next step is Choosing Channel 02 (CH02) NAME: Same process as for Channel 01 name. You may name all the channels available for the interpretation mode you are programming. If you don’t have a name for all the channels, then you may jump to the end of programming by holding the enter button for three seconds. (Unprogrammed channel names keep the default number as their name.)

9. SAVE: SAVE, SAVE AS PROFILE or CANCEL.

• Choose SAVE if you are ready to update the system now or soon.

• Choose SAVE AS PROFILE if you are planning to update the system at a later date and you may use the same DLT for other purposes between now and then.

10. UPDATE SYSTEM: NO or UPDATE SYSTEM NOW.

• Choose NO if you want to save your settings, but you are not ready to update the system.

• Choose UPDATE SYSTEM NOW if you are ready to synchronize with the MASTER and all DLTs and DLRs connected to that group.

11. UPDATE SYSTEM ARE YOU SURE? Choose UPDATE SYSTEM NOW to go ahead with the update.

• A bar showing the progress of the UPDATE will be visible both on the CONTROL units and the MASTER unit. Once the update has been done a pop-up window showing UPDATE OK will be visible on the control and master units. Channel naming will then be pushed out to all DLTs and DLRs which are connected to the group. Note: DLTs and DLRs need to be connected to the MASTER unit (within radio

range and turned on) when the update is done in order to be updated.

Verifying Channel Names

The current channel names programmed for the CONTROL unit are listed at the bottom of the display. You can

go scroll through the channels to see the names by using the up/down arrows.

Channel Sub-Groups

Channel subgroups are helpful in a situation where you don’t want all the channels to be visible to all participants. For example, this may be the case when a large hall is sometimes divided into two or more separate spaces. You can also utilize sub-groups to limit the number of channels visible on the receivers. For example, if only channels 01-16 are active in 24-channel mode, then you could set up a subgroup for channels 01-16 and program the DLRs to be in that subgroup for the receivers to avoid seeing non-active channels.

Programming Sub-Groups

1. Enter programming mode by holding the menu/select button for three seconds, choose your programming language, then select new settings.

2. MODE: Select INTERPRET, INTP24 or Q&A INTP.

• Make sure you choose the same mode as the MASTER unit of the Digi-Wave® system. If the modes aren’t the same, then the Control unit won’t be able to synchronize with the Master unit.

3. MASTER/GUEST?: Select CONTROL.

4. GROUP #: Choose the same group number as the MASTER of the system you wish to update.

5. SETUP SUBGROUP: YES.

You must choose a higher number for the last channel than the ﬁrst channel.

• CH 01-CH24 for INTP24.

7. SUBGROUP 2 - 1ST CHANNEL: CH 00-CH 14 for standard interpretation, CH 01-CH24 for INTP24. You must program at least two subgroups in order to use the sub-group feature. There can be overlap between the different subgroups. For example, you could have channels 01-05 for subgroup 1 and channels 03-08 for subgroup 2.

8. SUBGROUP 2 - LAST CHANNEL: CH 00-CH 14 for standard interpretation, CH 01-CH24 for INTP24. You must choose a higher number for the last channel than the ﬁrst channel.

9. ADD SUBGROUP 3: NO or YES. Optional.

10. ADD SUBGROUP 4: NO or YES. Optional.

11. ACTIVE SUBGROUP: NO or YES. If you would like to update subgroups as soon as you update the system, choose YES. If subgroups were previously active, the way to deactivate them is to go to this programming step and choose ACTIVE SUBGROUP = NO and then update the system.

12. After adding 2-4 subgroups, you are taken to the channel naming menu. See Channel Naming section for details. If you don’t want to name the channels, then you may jump to the end of programming by holding the enter button for three seconds. (Channel names will then have the default number as their name.)

13. SAVE: SAVE, SAVE AS PROFILE or CANCEL.

• Choose SAVE if you are ready to update the system now or soon.
