System Overview
The Digi-wave™ system is a patented, 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” (under “Support – Downloads - Tech Bulletins”).
A Digi-Wave communication system consists of at least one transceiver (DLT 300 ) and various combinations of transceivers and
receivers (DLR 360 ) depending on the venue.
The DLT 300 is a two-way transceiver, meaning that it can transmit and receive audio simultaneously. It can operate in one of 3
dierent modes:
1. In Two-way Mode, a speaker (with a DLT 300) can hear another speaker’s voice (from a second DLT 300) and,
at the same time, can also transmit their own voice. In this way, two-way communication is established (similar to a
phone conversation). Two-way mode can only be established between DLT 300 units. In addition, DLR 360 receivers
in the same group can also hear the broadcast.
2. In One-way Mode, one DLT 300 acts as a transmitter (speaker) and another DLT 300 acts as a receiver (listener).
In addition, DLR 360 receivers in the same group can also hear the broadcast. There are 4 one-way modes.
3. In Repeater Mode, the DLT 300 receives audio from another DLT 300 and re-broadcasts the signal to increase the
transmitted range of the person speaking. In this way, larger groups can be covered by using one or more DLT 300’s
acting as repeaters. Listeners can have either DLT 300’s or DLR 360’s to listen to the broadcast.
The Repeater function only operates in 1-way mode. It is not available in a 2-way scenario.
4. In Intercom Mode, up to six people can talk simultaneously. All of the DLT 300’s are in 2-way mode in the same
group. More DLT’s can be in the group, but only six can have live mics at the same time (the seventh DLT who wishes
to speak pushes their TALK button and knocks the sixth talker o). DLR’s can listen-in on the conversation if desired.
The DLR 360 is a receiver only. Users of receivers can only hear what is being broadcast by DLT(s).
Combinations of one or more DLT 300’s and DLR 360’s in One-way mode, Two-way mode, or Repeater mode can be used to
facilitate dierent 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. Rules of Operation for 1-way or 2-way mode must be followed for successful operation.
For simplicity, throughout the rest of this manual, the DLT 300 may be referred to as a “DLT” and the DLR 360 as a
“DLR”. Similarly, Master 1, Master 2 and Guest may be referred to as “M1”, “M2”, and “GST”.
The Digi-Wave 300 Series is not backward compatible with previous generation transceivers or
receivers (DLT 100, DLT 100 2.0, DLR 50, DLR 60, and DLR 60 2.0).

Getting Started: Preprogrammed Systems
If a system has been purchased, you should not need to perform any programming. The system will have been configured to
your order. Turn Master 1 on first so other units can pair. Guest units will turn o after 5 minutes if they cannot find a master.
1. Charge all DLTs. If using DLRs, either charge them with NiMH batteries or insert fresh Alkaline batteries. Make sure the
battery switch is in the correct position for “Alkaline” or “NiMH”. Any DLRs that will be used should have fresh batteries.
2. Identify and turn on the Master 1 first, usually identified by a grey silicone cover. Turn on the DLT by holding the power button
until the LCD screen comes on. If Master 2 or Guests are powered up first they will turn o after a few minutes if not paired
with the M1. As Master 2 and Guests are paired with the M1 the M1 and M2 will show C-#. The # refers to how many DLTs are
paired within the group, i.e. C-12 means that 12 DLTs are paired with the M1 or M2 within their group. This can be utilized as
an attendance checker making sure everyone is connected with the group.
3. Once all the DLTs are on, you can check the set-up status of all units by pressing the power/menu button momentarily to
scroll through the settings:
Master 1 and Master 2 screens will display (not necessarily in this order):
C-X (Chairman plus X = number of participants within the group).
Time Displays the time of day.
Group number (0 – 1023) must be the same number for the group.
ADD Address number (0 – 1023). Each DLT must have its own individual address.
“F-#” Denotes software version.
CODE Only shows if a code has been entered (code number will NOT be displayed).
Guest units will display:
Time of Day
Address Number
Software Version
Group Number
Secure Key Code (if entered)
4. If headsets are to be worn, plug them into the jacks on the top of the DLTs making sure that the Microphone and Earphone
plugs are fully inserted into the correct jacks.
5. The Master 1 will usually be the first speaker and should press the talk button momentarily to activate the microphone. This will
be confirmed by the red LED around the talk button illuminated. If the talk LED is flashing, the talk button was held too long and
the talk mute has been activated in the system. Hold the talk button until the LED’s stop flashing to deactivate talk mute.
6. The Master 2 and all Guest units should now be hearing audio from the M1 unit. Listening volume levels can be adjusted
by pressing the – or + button. One other DLT can activate the Talk button for team tour or teach applications. A maximum
of 2,3,4,5, or 6 microphones can be live at any one time (depending on 2-way mode chosen and maximum number of live
mics selected). For a Guest unit to talk, either the M1 or M2 will have to turn their talk button o by quickly pressing their talk
button.

DigiWave 300 Series Digital Transceiver and Receiver
10
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 M1 will have first priority, M2 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 DLTs or DLRs.
The M1 and M2 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.
There are 4 basic steps to programming a Digi-Wave system.
1. Decide which mode you need.
A. 2-Way Modes
In 2-way mode, DLTs can hear and talk to each other, just like having a phone conversation or a conference call. DLRs can
listen to the conversation. Common applications include: Tours with multiple Tour Guides, Tours with audience participation
(Q&A), Wireless Intercom, Portable Discussion and Personal Communication.
There are two 2-way Modes represented by these symbols on the LCD Display:
2-way: (4 simultaneous talkers maximum)
2-way - Intercom: (6 simultaneous talkers maximum)
Rules of Operation (2-way modes)
The following rules must be followed. Failure to adhere to these rules will result in unpredictable, unsupported operation.
• There must be one, and only one Master 1 (M1) per group.
• If the M1 unit is o, the Master 2 and Guest units will turn o after a few minutes.
• Master 2 is optional and there can only be one per group.
• Each DLT must have its own address and the address cannot be duplicated within a group.
• Maximum 4 talkers (in 2-way mode) or 6 talkers (in 2-way Intercom mode) can operate simultaneously within a group.
• Maximum four Groups can operate simultaneously within the same area, but each group must be assigned its own
group number.
• When using four simultaneous groups, group numbers must be sequential. i.e. 11, 12, 13, 14. Any numbers 0-1023 can
be used (or 0-99 if DLRs are used in the system).
• Attendee count will only work with addresses 1-99 (Maximum 100 DLT’s with one Master 1 at address 0).
• With Secure Key Code active, all DLTs within the group must have the same 4-digit code entered. (DLRs will not work
with secured DLTs)
B. 1-Way Modes
In 1-way mode, communication flows in one direction. It flows from the main speaker’s DLT, to secondary DLTs or DLR’s. If
repeater mode is used, the repeater DLTs listen to the primary DLTs and transmit to DLTs and DLRs assigned to the same
Group/Channel. The most common applications are: Simultaneous Interpretation with one or more interpreters, or Tours
without audience participation (no Q&A).
There are (4) 1-way Modes represented by these symbols on the LCD Display:
1-way - Main Speaker: (talks on Channel 0)
1-way - Interpreter: (receives on Channel 0, speaks on Channel designated for their language).
Within this mode Bilingual Interpretation Mode can be enabled or disabled. This allows an interpreter to quickly switch
their DLT to output on either channels 1 or 2. So if the floor is speaking in English, the bilinguist could be translating into
Japanese to the Japanese audience listening on Ch 2. When the floor changes to Japanese, the interpreter can quickly
change their output to Ch 1 and interpret Japanese into English to the audience listening in English.

DigiWave 300 Series Digital Transceiver and Receiver
11
1-way - Repeater Mode: (Units out of range of the primary unit(s) receive their broadcast from these units)
1-way - Interpretation with Relay Mode:
This allows the interpreter to quickly switch between listening to the Floor or the Relay. For example, the floor may
be speaking in English and the interpreter is interpreting English to Spanish. When the Floor changes to a French
speaker, the interpreter can quickly switch to the Relay, who is interpterting French into English, so the interpreter
can continue interpreting English to Spanish.
1-way - Listen Only: (receive the broadcast from either the primary units or the repeater units, depending on range)
Rules of Operation (1-way modes)
The following rules must be followed when setting up any Digi-Wave™ system. Failure to adhere to these rules will result in
unpredictable, unsupported operation.
• Up to 15 channels can be used simultaneously, i.e. one floor and 14 interpreters.
• There must be one Master 1 (usually this is also the floor), and only one, per group.
• Each Interpreter must be assigned their own channel number.
• Repeater function can only be used in 1-Way mode.
• When repeater function is used, all 15 channels can be utilized in one-way mode, i.e. one floor and 14 interpreters.
• When repeaters are used, Floor (channel 0) or Interpreter (channels 1-14) must be assigned as the master unit for the
group. All other DLTs have to be assigned as “GST”. When a Repeater is added to the system, the repeater must be set
as the Master.
2. Decide Speaking Priority for each DLT.
There are 3 levels of priority. The M1 has first priority, M2 has second priority and Guest units have third priority. The M1 or M2
will have to turn OFF their talk access to allow the Guest units to talk. When 2-6 people are talking in a group the participants
can hear their voices in the DLTs or DLRs.
The M1 and M2 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.
Speaker priority is assigned as follows:
1st priority — Master 1 ( M1 ):
2nd priority — Master 2 ( M2 ):
3rd priority — Guest ( GST ):
3. Decide what Address(es) you will need.
Each DLT transceiver must have a unique address. Refer to the “Rules of Operation” (under Step 1) for the mode you are using,
to determine how you will address the units.
4. Decide what Group(s) you need.
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.

DLT Secure Key Code:
When a group has been set up and the same Secure Code has been entered into all the DLTs, the DLTs without this Secure
Code entered cannot listen in on the group. This may be desirable in private or high security-level functions.
The same four digit code must be programmed into all of the DLTs, Master 1, Master 2 and Guests. If a dierent secure code
has been entered, participants cannot re-enter the group without re-entering the correct secure code. The only time the Secure
Code is displayed is when it is being entered. To block users from entering the set-up mode, refer to the SETUP LOCK (SLOC)
feature (see “DLT Set-Up Lock (SLOC)” on page 6).
1. Choose a 4 digit numerical code; i.e. 1357. You must use the same code on each DLT in the group.

Example 1: Tour Guide (2-way, up to 4 open microphones)
HOW IT WORKS
Up to four (4) people can have open microphones (TALK button on) 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 set up as a Guest unit. When a 5th person desires to speak, they push their
TALK button and this knocks the first Guest unit o (deactivates their talk button). The first Guest unit to turn their mic on is also
the first Guest unit to be knocked o when the 5th unit wants to join the conversation. This First-In-First-Out (FIFO) order continues
each time a member pushes their TALK button who is not a part of the live group.
Every DLT can either be used alone (built-in speaker) or with a compatible headset microphone (pictured).
1. The Tour Guide speaks, using the Master DLT.
2. Each Tour Group Member using a listens directly to the Tour Guide using a Guest DLT.
3. At this point Tour Members 1-3 microphones are “live” (TALK buttons on) so they can speak at any time. Tour Member 1 asks
a question, the Tour Guide hears their question, then speaks, and everyone in the Group hears the question and the answer.
4. Tour Member 4 then has a question. With the push of their TALK button, they deactivate Tour Member 1 DLT and ask the Tour
Guide a question. All Tour Group Members listen to the question, and hear the answer through their DLT.
5. Another Tour Member can ask a question by pushing their TALK button and knocking someone else o. This can continue indefinitely
but only 4 DLTs can have “live microphones” at the same time.
6. The Tour Guide has the ability to take control of the discussion by overriding Group Member (Guest) units, if needed. This is
accomplished by pushing-and-holding their TALK button down which mutes all Guest unit microphones.
7. A second Tour Guide may be added (as a MASTER 2 unit, not pictured) and this unit also can take priority over Guest units.
Master 1 and 2 units have two-way communication capability; they can talk/listen simultaneously to one another. Tour Group
Members can participate as listen-only or can ask questions with the quick push of a button.

Example 2: Simultaneous Interpretation Mode (1-way, up to 14
languages)
HOW IT WORKS
The “Floor” unit (main presenter) transmits on channel 0. All interpreter units receive 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.
1. The Main Speaker will use channel 0; Press the TALK button to activate the microphone
2. Each Interpreter unit will need to be assigned a channel number (1-14). The TALK button must be activated to send the
interpretation to the attendees.
3. The floor speaks, using a DLT alone (built-in mic) or using it with a compatible headset mic.
4. Interpreter listens directly to the floor, using a DLT alone (built-in speaker) or using it with a compatible headset mic.
5. With the push of a button, interpreter simultaneously interprets to the listeners, using a DLT alone (built-in mic) or using it with
a compatible headset mic.
6. Each listener hears the interpretation using a DLR.
An additional DLT can be set-up as a repeater to increase the range of each channel. The Repeater Function can only be used
in simultaneous interpretation mode. See section “Repeater Mode” for details.
The 3.5mm stereo microphone jack can accept a headphone level or a line level output from audio sources when using the
Williams Sound WCA 094 attenuated cable.
