DV-2000 MTS/LR · Digital autoload storecaster with music-thru and local record

Models

The DV-2000 MTS/LR is a message-on-hold and storecasting system with local recording. It combines audio playback, background music (BGM), selectable messages and recording features, and stores up to 20 messages in non-volatile FLASH memory, each with its own enable switch. Audio fidelity is 6.8 kHz (PRO) with a 60 dB signal-to-noise ratio. Messages load from cassette, or are recorded live through the optional handset for last-minute changes or frequently updated material.

• DV-2008 MTS/LR PRO: 8 minutes, 6.8 kHz
• DV-2016 MTS/LR PRO: 16 minutes, 6.8 kHz
• LR-HSET (option): local record handset and cable

Installation

Before installing, make sure there is a message-on-hold or music-on-hold input on the phone system, or a line level input on the public address system, and a non-switched 110 VAC outlet near the unit. The box holds the DV-2000 MTS/LR, a power pack, an audio cable, mounting hardware and the user’s manual.

• Mount the unit on the telephone equipment board or wall in one of three positions: back against the wall, flat (10 × 8 in); left side against the wall (2.2 × 8 in); or left side against the wall horizontally (8 × 2.2 in). Mark the mounting holes and secure it with the screws provided.
• For table top use, stick the enclosed rubber feet on the bottom of the unit.
• Plug the power pack into a 120 VAC outlet that is not controlled by a switch, then into the jack marked 12VDC. There is no power switch; the system is active as soon as power is connected.

Connections

Telephone system: connect the supplied RCA cable from LINE OUT to the message-on-hold input. PA system: connect an RCA to RCA cable from LINE OUT to the PA amplifier’s line level input. In both cases use LINE OUT first and set the level with the audio output potentiometer; if that does not give enough level, switch to SPKR OUT.

• 12VDC: 2.5 mm barrel connector; use only the AC-DC power adapter supplied by the manufacturer.
• BGM IN (RCA): 10 kΩ, transformer isolated audio input for the output of the background music source, such as CD or satellite.
• LINE OUT (RCA): 600 Ω, transformer isolated, +4 dB line level output; connect it to the phone system or PA system first.
• SPKR OUT (RCA): amplified output, 1 W into 8 Ω, for when the line output cannot drive the on-hold circuit or PA amplifier to a high enough level.
• HANDSET INPUT (Local Record, RJ11): input for the optional LR-HSET local record handset.

Loading messages from cassette

A new DV-2000 MTS/LR has a blank memory. Insert a pre-recorded, properly formatted cassette with the audio side toward the top of the unit (tape up, facing the label). The unit rewinds the tape, plays it and records each audio program into memory, ignoring the silence between them. The red Record LED is on while a message is recorded and goes out when the unit detects 6 seconds of silence; the unit keeps playing the tape and records the next message it finds. 15 seconds of silence mark the last message, and the tape is rewound. Playback then starts automatically from memory. The audio being recorded is sent to the line and 8 Ω outputs and can be heard on the monitor speaker.

The Append / Replace pushbutton selects one of two download modes; the setting is not kept when power is removed and reapplied.

• Mode 1, Replace All (Replace/Append LED off): as soon as the tape is inserted, every message in memory is erased, and the messages on the tape are recorded starting from message 1. Even if the tape is ejected before any audio is recorded, the memory stays empty. Use it whenever all messages need updating.
• Mode 2, Replace and Append (Replace/Append LED on): turn ON the message selection switches of the messages to overwrite and OFF those to keep, then insert the tape. The first message on the tape replaces the first enabled message, the second the second, and so on; extra messages on the tape are appended until 20 messages are stored or the tape ends.
• Example: with ten messages stored, enabling only switches 3 and 7 and inserting a tape with five messages records them into locations 3, 7, 11, 12 and 13.
• To only append messages, select Replace and Append and turn all message selection switches off; the messages on the tape go into the empty locations.

Recording with the local record handset

With the optional LR-HSET handset, a custom recording can be made directly into any of the 20 message locations and updated at any time.

• Plug the LR-HSET into the Local Record input.
• Press the green Local Record pushbutton; the red Record LED blinks.
• Toggle the desired message location switch twice to begin recording; the Record LED then stays on. A disabled location is toggled up then down, an enabled one down then up.
• Record the message into the handset, then press the red Record button to stop.
• A preview of the message plays automatically after recording stops. Leave the location switch up (enabled) for the message to play back.

Playback and message selection

After loading, all enabled messages play automatically in sequence with no user input, separated by the music interval; an enabled location with no recorded message is skipped. Between messages the unit outputs the background music, fading it up after a message and down just before the next one.

• Message selection switches 1 to 20: ON enables a message for playback and OFF skips it. In Replace and Append mode, enabled messages are overwritten and disabled ones are protected; in Replace All mode the switches are ignored while recording. Changes are recognized during normal operation.
• Play Mode switch, Music Only (up): no messages play; the BGM goes straight to the output.
• Play Mode switch, Music and Message (middle, default): messages play in sequence at the music interval with the BGM mixed under them; between messages the BGM goes straight to the output.
• Play Mode switch, Message Only (down): messages play at the music interval and the BGM is muted; the output is silent between messages.
• Music Interval: the TENS and ONES rotary switches set 00 to 99, and the MIN/SEC slide switch to their right sets minutes or seconds. The setting is read during operation and can be changed while messages play.

Controls and indicators

• Eject / Rec Stop pushbutton (red, momentary): ejects the tape when the unit is not recording. While recording, a short press stops recording, saves the audio and rewinds the tape without ejecting it; a second short press also ejects the cassette without rewinding; holding it for two seconds deletes the message just recorded and ejects the tape without rewinding.
• Append / Replace pushbutton (black, momentary): toggles the Replace and Append download mode.
• Speaker pushbutton (black, locking): turns the front monitor speaker on and off, to preview recording and playback. Its volume follows the audio output level; do not raise the output level to hear the monitor better.
• Local Record pushbutton (green, momentary): starts local recording.
• Eject LED (yellow, NO TAPE on the Quikey): on when no tape is in the system; goes out when a tape is fully loaded.
• Record LED (red): on while an audio program is recorded; blinks in local record setup mode, and blinks once at power-on to show that the memory is operational.
• M-O-H LED (green, PLAYING on the Quikey): on in automatic playback while messages play or BGM is output.
• Append / Replace LED (red): off in Replace All (standard) mode, on in Replace and Append mode.

Audio adjustments

• LEVEL: sets the 600 Ω and 8 Ω outputs together; clockwise raises the level, counterclockwise lowers it.
• APHEX: psycho-acoustic processing that extends the high frequency response; clockwise amplifies the high frequencies, counterclockwise attenuates them.
• BGM LEVEL: overall level of the background music input; clockwise raises it.
• BGM FADE DOWN / UP pushbuttons (black, momentary): set how much the BGM is ducked (attenuated) under a message. Each press changes the BGM by about 1 dB; held down, about 8 dB per second.

Tape production format

• Record messages on the left channel (track A).
• Messages may differ in length; their total must not exceed the unit’s memory. The silence between messages does not count toward recording time.
• Set the nominal level to 0 VU = −4 dBm, and keep the dynamic range low so the production records at the highest level without exceeding +5 VU = +1 dBm.
• For best results, filter out frequencies above 6.8 kHz.

Power failure

FLASH memory keeps the messages without power or battery backup, so brownouts and power losses do not affect them. When power returns, the system resumes the operation it was in before the power was removed. The Replace and Append mode is not kept.

Troubleshooting

• No LEDs on → normal after a tape is inserted and before audio is detected; otherwise check that the power adapter is in a non-switched outlet and fully plugged into the unit.
• The tape will not load → push the cassette fully in; check the power adapter and power connector.
• The tape is ejected right after loading → in Replace and Append mode the memory is full or all messages are used, or the tape is an endless loop.
• The Record LED never comes on → check that the tape is right side up and not blank, and that its nominal recorded level is above −20 dB.
• The tape ejected after recording and no message plays → holding the Eject button during recording ejects the tape immediately; check the tape side; a tape with no audio is ejected at its end.
• Nothing heard from the audio output → if the Record and M-O-H LEDs are both off, there is no output; check the RCA cable at both ends, turn the output level clockwise, or use the 8 Ω output instead of the line output.
• Nothing heard on the monitor speaker → if the Record and M-O-H LEDs are both off, no messages are recorded; lock the Speaker button down; a low output level also makes the monitor quiet.
• Not all messages on the tape were recorded → noise in the silences between messages can group several messages into one location; in Replace and Append mode, the tape may hold more messages than there are enabled or free locations.
