1. OVERVIEW
The DV-2000 MTS/LR is a versatile Message-On-Hold and Storecasting System, now with Local
Recording capability. The MTS/LR combines high quality audio playback, background music,
selectable messages, remote control and recording features for use in even the most demanding
applications.
1.1 Features and Benefits:
The DV-2000 MTS/LR is a highly reliable audio playback system specifically designed for
Message-On-Hold and Storecasting applications. The system allows music and marketing
messages while clients are waiting on-hold or in your retail location. This heightens
awareness and minimizes frustration, thus increasing sales.
Message material may be loaded into the system via a ruggedized, electronically controlled
cassette mechanism originally designed for automotive applications and providing years of
reliable service. In addition, messages may be recorded live via the local record
handset(optional) , for last minute changes or frequently updated material. Messages are
digitized and stored in non-volatile FLASH memory that protects them from loss during power
outage.
The DV-2000 MTS/LR supports up to 20 individual messages. Each message has an enable
switch that allows the user to manually select which messages will be played for a particular
application. The Background Music(BGM) input is for combining messages with an external
music source such as CD or satellite. A built -in timer lets the user determine the time
between message plays.
Multiple audio outputs(600ohm,8ohm) with level control, Aphex®, and high quality sampling
allow the sound of the DV-2000 MTS/LR to be optimized for almost any phone or public
address system, insuring that the message gets heard.

3. Operation:
3.1 Message Downloading - Cassette:
When you receive the new DV-2000 MTS/LR Storecasting system, its memory will be blank.
To load new messages into the DV-2000 MTS/LR’s memory, simply insert a pre-recorded, and
properly formatted(Section 6), cassette tape into the DV-2000 MTS/LR unit. Make sure to
insert the tape with the side which audio is on facing toward the top of the machine.
When a new tape is inserted, the DV-2000 MTS/LR will automatically rewind the cassette to
the beginning and start playing it. The DV-2000 MTS/LR will record the audio program(s),
ignoring the silence segments on the cassette. When the Audio program on the tape starts,
the red Record light will come on signifying that Audio is being recorded. At the end of the
Audio program, when the DV-2000 MTS/LR detects 6 seconds of silence, the Record LED will
go out. The system will keep playing the tape while it “looks” for another message on the tape.
If another message exists, the red Record light will go on signifying that another message is
being recorded. When the last message on the tape is recorded, signified by 15 seconds of
silence, the system will automatically rewind the cassette tape.
The DV-2000 MTS/LR system offers two Message Download Modes; Replace All and Replace
and Append. See below for details.
3.1.1 Message Download Mode 1 - Replace All (Replace/Append LED: OFF)
When this mode is used, the system will erase all the messages in memory as soon as
the tape is inserted. The system will begin recording the messages from the cassette
tape into memory starting from message #1 and continuing through the last message on
the tape. Use this mode any time all of the messages on the DV-2000 MTS/LR system
need to be updated.
Important: Once a tape is inserted into the DV-2000 MTS/LR system, in this mode,
all of the messages in memory will be deleted immediately. Even if the tape is then
ejected prior to recording any audio, the DV-2000 MTS/LR’s memory will be empty.
3.1.2. Message Download Mode 2: Replace and Append (Replace/Append LED: ON)
This mode allows the user to add or replace any number of messages on the system.
Activate this mode by pressing the Replace/Append button until the Replace/Append
LED lights. Turn ON the message selection switches of the messages to be overwritten.
Make sure to turn OFF the message selection switches of the messages you want saved.
Insert the tape with the new messages on it and the system will rewind the cassette and
start playing it. The first message on the tape will overwrite the first active message,
signified by its message selection switch being ON. The second message will replace
the second active message, and so on.
6

If there are more messages on the cassette tape then there are messages on the
machine set up to be overwritten, the DV-2000 MTS/LR will append the extra messages
until there are twenty messages recorded on the system, or until the last message on the
cassette tape is reached.
Example: The DV-2000 MTS/LR system has ten messages currently recorded on the
system. To replace message 3 and 7 with new messages and add three more messages
to the system follow the steps below:
1. Activate the Replace/Append mode.
2. Enable message selection switches 3 and 7.
3. Disable all other message selection switches.
4. Insert the cassette tape which has the five new messages on it.
5. The system will record the first message on the tape into message location #3.
6. The system will record the second message on the tape into message location #7.
7. The system will then record the last three messages of the cassette tape into locations
#11, 12, and 13 on the DV-2000 MTS/LR, respectively.
It is not necessary to enable a message location to Append messages to memory. If the
user wants to simply append messages to the system, activate the Replace/Append
mode and disable all of the message selection switches. Insert the cassette tape with the
new messages into the DV-2000 MTS/LR and it will record the messages on the tape to
any empty message locations on the machine.
The Audio being recorded will be output though the 8 ohm and line outputs during the
recording process. This audio may also be monitored locally by depressing the “Speaker”
button.
3.2 Message Downloading - Local Record Handset:
You may also create messages for the DV-2000 MTS/LR by recording them directly to the unit
using the optional LR-HSET handset. This feature allows you to make a custom recording to
any of the 20 message locations on the unit. These messages may be updated at any time for
maximum flexibility.
1. Plug the LR-HSET(sold separately) into the Local Record Input.
2. Press the Local Record pushbutton to initiate the record sequence, Record LED(RED) will
blink.
3. Toggle the desired message location switch two(2) times to begin recording.*
4. The Record LED should now be illuminated, record your message into the handset.
5. Press the Record(RED) button to stop recording.
6. A preview of the message will automatically be played after the recording has been stopped.
*NOTE: Local recordings may be made to message locations that are either enabled or
disabled. If disabled, toggle the switch up then down to begin recording. If the message
location is enabled, toggle the switch down then up to begin recording. Always leave the switch
up, or enabled, if you want it to playback.
3.3 Automatic message playback
After messages have been recorded into memory, the DV-2000 MTS/LR will automatically
begin playing them through the audio outputs. There is no control, or user input, required to
initiate the playback. The green, Audio LED will light whenever the system is playing
messages.
All enabled messages will be played back sequentially. If an enable switch is active, but has
no associated message recorded into that position, the position will be skipped.
The messages in memory are automatically played back sequentially with a user programmed
delay time inserted between them(see section 3.7 for delay configuration information).
7

In between pre-recorded message plays, the DV-2000 MTS/LR will output the background
music, BGM, audio to the audio output. The DV-2000 MTS/LR will gently fade the BGM
audio up after a pre-recorded message is played, and it will gently fade the BGM audio
down just prior to a pre-recorded message play.
3.4 Pushbutton descriptions
Eject / Rec Stop pushbutton – Red, momentary
Allows the user to stop the recording process, in several ways, and/or eject the tape.
-When the system is not recording, the button functions as an Eject button.
-When the DV-2000 MTS/LR is recording audio, (whenever the Record LED is on) pressing
this button momentarily will stop the recording and save the Audio which was just
recorded. The system will rewind the tape, but not eject it.
-If this button is pressed and held for two seconds while the DV-2000 MTS/LR is recording,
the message just recorded will be deleted, and the tape will be ejected without being
rewound.
-If the button is pressed momentarily while the DV-2000 MTS/LR is recording audio, and
then pressed momentarily again, the system will stop the recording process, save the
Audio just recorded, and eject the cassette tape without rewinding it.
Append / Replace pushbutton – Black, momentary
Pressing this button toggles the Replace/Append mode. The status of the Append and
Replace mode is signified by the Replace/Append LED. When this LED is on, the system is
in Replace/Append mode. This setting is not saved when power is removed, and reapplied
to the unit.
Operation of the unit in Replace/Append mode is described in the Message Download
section(3.1).
Speaker pushbutton – Black, locking
A monitor speaker, on the front side of the unit, allows the local user to hear the Audio being
output by the DV-2000 MTS/LR. Pressing this button will activate the monitor speaker.
Releasing the button will deactivate the monitor speaker.
The volume of the monitor speaker is determined by the volume setting of the Audio output.
If the phone system requires a particularly low level from the DV-2000 MTS/LR, the volume
of the monitor speaker will also be low.
Note: Do not adjust the Audio output level adjustment in order to hear the monitor
speaker level better. Doing this will adjust the level of the Audio output which may
not be acceptable.
Local Record pushbutton – Green, momentary
Pressing this initiates local recording.
3.5 LED (Light Emitting Diodes) descriptions
Eject LED, Yellow
This LED will light whenever the tape is ejected, i.e. no tape in the system. When a tape is
inserted, and loaded, i.e. tape is completely inside the machine, this LED will go out.
Record LED, Red
This LED will light when the DV-2000 MTS/LR starts recording an Audio program, and will
go out when the recording process stops. This LED also blinks while the system is in local
record setup mode.
The Record LED will blink one time when the DV-2000 MTS/LR is powered on, indicating
that the memory operational.
M-O-H LED, Green
This LED will light whenever the DV-2000 MTS/LR is in automatic playback mode and
playing messages, or outputting the BGM audio.
10

Mode - Append / Replace, Red
This LED indicates the message download mode. When this LED is OFF, the system is in
Replace All mode. When this LED is ON, the system is in Replace and Append mode. This
setting is not saved when power is removed, and reapplied to the unit. Operation of the unit
in Replace/Append mode is described in the Message Download section.
3.6 Audio adjustments
There are three potentiometers and two pushbuttons on the DV-2000 MTS/LR system allowing
the user to tailor the BGM level, the audio output level and high frequency response. Refer to
the Quikey for location of each control.
Audio level
The level of the both 600 and 8 ohm Audio outputs are simultaneously adjusted using the
Audio level adjustment pot. Turning this potentiometer counter clockwise will lower the
Audio level. Turning this potentiometer clockwise will raise the Audio level.
Aphex®
A special, psycho-acoustical processing extends the high frequency response of the
DV-2000 MTS/LR. Turning this potentiometer counter clockwise attenuates the high
frequencies while turning it clockwise amplifies the high frequencies.
BGM In
This sets the overall level of the background music being fed into the DV-2000 MTS/LR.
Turning this potentiometer counter clockwise will lower the BGM level. Turning this
potentiometer clockwise will raise the BGM level.
BGM Fade
Two pushbuttons are provided on the top cover allowing the user to set the amount of
“ducking” to be applied to the BGM audio when a pre-recorded message is played by the
system. The BGM audio is mixed with the pre-recorded message audio, and this setting
governs the amount of BGM audio being mixed. “Ducking” is the amount which the BGM
audio level is attenuated, or lowered.
BGM Fade Down pushbutton – Black, momentary
Pressing this button will increase the ducking amount, or, in other words, lower the BGM
audio being mixed in with the audio output when a pre-recorded message is played.
Pressing the button one time will attenuate the BGM audio approximately 1dB. If the button
is pressed and held, the BGM level will be lowered approximately 8dB per second.
BGM Fade Up pushbutton – Black, momentary
Pressing this button will decrease the ducking amount, or, in other words, increase the
amount of BGM audio being mixed in with the audio output when a pre-recorded message
is played. Pressing the button one time will raise the BGM audio approximately 1dB. If the
button is pressed and held, the BGM level will be raised approximately 8dB per second.
3.7 Slide Switch descriptions
Several slide switches are provided on the top cover of the DV-2000 MTS/LR. These switches
control the functions described below:
Message Selection Switches
The DV-2000 MTS/LR system can record and play up to 20 messages. Each message has
a message selection switch associated with it. These switches allow the user to enable or
disable messages to be played, or recorded. The system will recognize changes of the
message selection switches during normal operation.
When a message selection is in the “ON” position, the message is enabled. When the
DV-2000 MTS/LR is in play mode, it looks at the switch for all recorded messages. If the
message is enabled, the system will play the message. When a message selection switch
is in the “OFF” position, the message is disabled. If the switch is disabled, the system will
skip the message.
When the DV-2000 MTS/LR is in record mode with Append/Replace mode active, the
system will overwrite any messages whose message selection switch is enabled, while
protecting the messages whose message selection switch is disabled. All message 11

selection switches are ignored when the system is recording and the Append/Replace mode
is not active.
Play Mode
The DV-2000 MTS/LR system has three play modes, Music Only, Message Only, and Music
and Message. A three position slide switch sets the mode of the system.
Music Only – No pre-recorded messages are played when the system is in this mode. The
system will simply route the BGM audio directly to the output.
Message Only – Pre-recorded messages will be played sequentially based on the Music
Interval setting. The BGM audio will be muted, however. No audio will be present on the
audio output connector between pre-recorded message plays.
Music and Message (Default) – This mode allows Pre-recorded messages to be played
sequentially based on the Music Interval setting. When a message is playing, the BGM
audio will be mixed in with the pre-recorded audio. Between pre-recorded message plays,
the BGM Audio will be routed directly to the audio output.
Music Interval
Two Rotary switches and a slide switch make up the Music Interval setting. The two rotary
switches allow for a setting from 00 to 99. The left rotary switch represents the “tens”
position, while the right rotary switch represents the “ones” position. The slide switch to the
right of the rotary switches sets whether the 00 to 99 setting is in minutes or seconds.
These switches are read by the system during operation, so changing the setting can be
performed while the unit is playing messages.
3.8 Connections
12VDC, 2.5mm Barrel connector
The system is powered by 12VDC. Use only the AC-DC power adapter supplied by the
manufacturer to guarantee proper operation.
BGM IN, RCA connector
A 10K ohm, transformer isolated, audio input. When installing the DV-2000 MTS/LR
system, connect this input to the output of the background music source.
LINE OUT, RCA connector
A 600 ohm, transformer isolated, Audio output. When installing the DV-2000 MTS/LR
system, connect this output to the phone system, or PA system, first.
SPKR OUT, RCA connector
An amplified, 1 watt into 8 ohm, Audio output. Use this Audio output if the Audio from the
Line output can’t drive the on-hold circuit, or PA amplifier, to a high enough level.
Local Record, RJ11 connector
Local record input for connecting an optional handset(LR-HSET).
4. Power failure recovery
The DV-2000 MTS/LR uses FLASH memory which is not dependent upon power or battery
backup to retain its memory. This eliminates problems associated with brown outs or unexpected
power losses. When power is returned, the system will immediately start the operation it was in
prior to power being removed.
5. Troubleshooting guide
Before contacting the factory, please review the following answers to some common problems.
No LEDs are active on the DV-2000 MTS/LR.
•When a tape is inserted, and before audio is detected by the system, all LEDs will be off.
•Verify that the AC-DC power adapter is plugged into non-switched AC power outlet.
•Verify that the power connector is plugged completely into the jack on the
DV-2000 MTS/LR.
12

The system will not mechanically load the tape into the system
•Push the cassette tape completely into the DV-2000 MTS/LR.
•Verify that the AC-DC power adapter is plugged into non-switched AC power outlet.
•Verify that the power connector is plugged completely into the jack on the DV-2000
MTS/LR.
The system ejects the tape immediately after it is loaded.
•If in Append & Replace mode and the memory is full.
•If in Append & Replace mode and all of the messages are used.
•If it is an endless loop tape.
The Record LED never comes on after the cassette tape is loaded into the system
•Verify that the tape was inserted right side up.
•If the tape is blank, the Record LED will never come on.
•Verify that the nominal level of the Audio recorded on the tape is over –20dB.
After recording the tape, the tape ejected, and the system is not playing a message.
•Pressing, and holding the edit/eject button while recording will eject the tape immediately.
•Verify that the tape was inserted right side up.
•If there is no audio on the tape, it will eject automatically when it reaches the end of the
tape.
Can’t hear anything from the audio output
•If both Record and M-O-H LEDs are off, there is no audio being output by the system.
•Verify that the RCA to RCA connector is securely attached to the DV-2000 MTS/LR and the
phone system.
•Turn the output level adjustment clockwise to increase the Audio output level.
•Use the 8 ohm output instead of the line level output.
Can’t hear anything through the monitor speaker
•If both Record and M-O-H are off, there are no recorded messages on the system.
•Press the Speaker button so that it locks in the depressed position.
•If the audio output is adjusted low, the level from the monitor speaker will also be low.
The system didn’t record all the messages on the tape
•If there is noise in the silence portions separating the messages on the cassette tape,
multiple messages can get grouped into a single message location on the system.
•If in Append/Replace mode, the tape has more messages on it than there are locations
enabled or available on the system.
6. Audio Tape Production Format:
•Messages must be recorded on the left channel or track A.
•The length of individual messages do not have to be the same, but the total length of all
messages should not exceed the total memory capacity of the unit.
•The silence portion between messages is not included in the maximum recording time.
•The audio should be set to a nominal level of 0VU = -4dBm.
•For best results, the audio should be filtered to cutoff any frequencies higher than 6.8kHz for
the PRO version.
•The dynamic range of the production should be held low so as to allow the production to be
recorded at the highest possible level without exceeding +5VU = +1dBm.
The system requires 1 seconds of constant audio at a level greater than -20dBm for the
system to acknowledge the production and start recording. This is required so that the
system can discriminate between tape noise and message material.
