System Overview
Thank you for purchasing the DWD 102 Digi-Wave™ Dual-Bay Docking
Station.
The Digi-Wave™ Dock, when used with second-generation Digi-Wave 2.0
products, can be used to receive audio through a Digi-Wave™ receiver (or
transceiver) and send the audio into a sound system, or send audio from a
sound system to a transceiver for broadcast. There are many applications for
the dock; for more information please visit our website and download the Digi-
Wave Dock Applications Guide.
The Digi-Wave™ Dock supports audio input/output functions with the DLT 100
2.0, DLR 60 2.0 and DLR 60 models. It will only act as a charger for the DLT
100.

Setup Instructions:
1. Connect the external devices to the XLR or RCA jacks on the back of
the Digi-Wave™ Dock (Figure 1). Both RCA and the single XLR input
jacks are all mixed internally - but for proper mixing to occur at the output
without any adjustments, the following combinations can be used: One
single RCA jack by itself, both RCA jacks, the XLR jack by itself, or both
RCA jacks and the XLR jack. If one RCA jack is to be mixed with the XLR
jack, the gain of the RCA source will need to be adjusted at the source.
2. Select DLT mode. We recommend using “Chairman Master” mode for
two reasons: (1) The Chairman Master has #1 Talk Priority so the Talk
button on this unit can never be bumped o by another user, and (2)
The Chairman Master will be powered by the dock, and all other units
synchronize to the Chairman Master, making it a more reliable Master
than one powered from the internal battery.
3. Insert any combination of DLT 100 2.0 transceiver(s) or DLR 60 2.0
receiver(s) into the bays (Figure 2). The unit(s) must be facing forward for
proper mating to the 30-pin connector.
4. Using the appropriate line cord (US, EURO, UK or AUS) into the TFP 048,
plug the TFP 048 power supply into the AC wall outlet. Plug the power
connector into the rear of the DWD 102 unit (gure 1). The green LED
power indicator should light up (Figure 2).
5. Select either Auto or Manual for each docked device, using the switch(es)
on the back. See Figure 3 for an explanation of the dierence between
the two modes.
You may charge any combination of DLT 100 2.0, DLT 100, DLR 60 2.0, or
DLR 60s. (In DLR 60 2.0 and DLR 60 units, NiMH batteries must be used and
the battery switch must be in the NiMH position.) Digi-Wave™ Dock audio
inputs/outputs are only available on the DLT 100 2.0, DLR 60 2.0, and DLR
60. DLT 100s can be docked but will charge only (no audio). See Digi-Wave™
Dock Functions chart (Figure 3).
Note: It is safe to leave the DLT and DLR units in the charger, even after
the batteries are fully charged. The charger will switch to ‘maintain’
mode to maintain full battery potential.

DLT microphone mixing with dock sources
The dock’s inputs - two mono RCA jacks (-10dBV) and one XLR jack (+4dBu)
- are mixed together in the dock, then sent to the DLT 100 2.0. The DLT 100
2.0 then mixes the dock audio with it’s microphone before transmitting.
Depending upon what sources are being mixed, there may be a level
mismatch between the dock and the DLT’s microphone level. The DLT 100
2.0 includes line-level adjustment for proper mixing.
To adjust the DLT 100 2.0 line-level gain, hold the “^” button for 3 seconds.
The default level is “L:5”, or 0dB of gain adjustment. See Figure 4 below for
level settings and corresponding gain/attenuation.

Note: The “microphone volume” adjustment can also be used, but may
require other DLTs microphone levels to be adjusted too, which makes
it a more cumbersome method, and therefore line-level adjustment is
recommended.

Installing the Support Pads
Two sets of supporting pads have been supplied with the dock to support the
back of the unit(s) when sitting in the dock; thick (1/8”) and thin (1/16”). Use
the table below to choose which pad thickness to use (Figure 5). See the
diagram below showing where to affix the pads (Figure 6).

Specications subject to change without notice.
New batteries have various charge conditions. Some DLT/DLR’s may take
less or more time to fully charge. Charging batteries generates heat. The
receivers, transceivers, charger, and power supply may feel warm when
charging. Do not charge units in a closed enclosure, such as a carry case or
brief case.

Troubleshooting
No audio transmitted from docked DLT 100 2.0:
1. Make sure the DLT is seated rmly on the dock’s 30-pin connector.
2. Make sure the dock and DLT are powered ON.
3. Check the source input into the dock - make sure it is connected, powered
on and playing/producing audio.
4. Verify that the incoming audio level is sucient.
5. Make sure the TALK button red ring light is ON on the DLT.
6. Make sure the DLT is set up as a Chairman Master (recommended). Other
modes can be used but talk priority may cause the docked DLT to go o-air
when another unit enables the TALK function.
7. Make sure the DLT and DLR(s) are on the same Group.
8. Verify the DLT is transmitting audio. Take it out of the dock, talk into the
on-board microphone, listen with a DLR receiver and make sure it is receiving
audio. When this is veried, put the DLT back in the dock.
9. Verify the DLT 30-pin attenuator setting is not 0, as this mutes the dock
input.
No audio received by docked DLT 100 2.0 or DLR 60 2.0:
1. Make sure the DLT (or DLR) is seated rmly on the dock’s 30-pin connector.
2. Make sure the dock and DLT or DLR are powered ON.
3. Make sure the sending and receiving transceiver/receiver are both on the
same Group.
4. Make sure the TALK button red ring light is ON on the DLT that is serving as
the transmitter.
5. Make sure the receiving DLT/DLR is receiving audio. Take it out of the dock,
listen to the on-board speaker and make sure it is receiving audio. When this
is veried, put it back in the dock.
6. Check the dock output for the bay by connecting the RCA or XLR outputs
to a device that will show or produce audio, such as a boombox or small mixer
with VU meters.
7. Make sure the device receiving audio from the dock is connected, powered
on, and if applicable - on the correct bay/output for the dock (the two bays are
not connected).
8. The audio output level is dierent for the RCA and XLR jacks. Make sure the
correct output is being used for the connected equipment.

10
One or more source audio levels too quiet or too loud (not
mixing evenly):
1. If the RCA inputs are being used with an XLR source, both RCA inputs
must be used to mix evenly with the XLR source. If using a mono RCA source,
it must be wyed-out (using a Y-cable or adapter) and sent into both RCA
inputs. If just one RCA is used, when mixed with the XLR, it will not mix evenly
and will be quieter than the XLR source.
2. If the DLT microphone level is not mixing evenly with the XLR and/or RCA
sources, adjust the DLT line input level to match the microphone audio level
(see section on “DLT microphone mixing with dock sources”.
3. If the transmitted audio is distorting, turn the DLT line level down (see
section on “DLT microphone mixing with dock sources”), or turn the audio level
down at the source.
DLT/DLR not charging or indicating charge:
1. Make sure the DLT or DLR are seated rmly on the dock’s 30-pin
connector(s).
2. Check that the line cord is rmly plugged into the power supply, the power
supply is plugged into the AC outlet, and the power supply connector is
plugged in on the back of the Digi-Wave™ Dock inserted rmly until it stops.
3. Verify the dock’s green power LED is ON.
Note: DLTs do not indicate charge status when powered ON, but DLRs do.
4. On DLR, verify the NiMH batteries are installed correctly (not reversed) and
battery switch is set to “NiMH” position.
