DV-2000 · Digital autoload message-on-hold system, STD and PRO models

Models

The DV-2000 is a digital autoload message-on-hold system. Messages are loaded from a standard cassette into non-volatile FLASH memory and play continuously from memory until new messages are loaded. Audio fidelity is 100 Hz to 3.4 kHz on the STD version and 100 Hz to 6.8 kHz on the PRO version, with a 60 dB signal-to-noise ratio.

• DV-2004: 4 minutes, 3.4 kHz
• DV-2008: 8 minutes, 3.4 kHz
• DV-2016: 16 minutes, 3.4 kHz
• DV-2032: 32 minutes, 3.4 kHz
• DV-2008 PRO: 8 minutes, 6.8 kHz
• DV-2016 PRO: 16 minutes, 6.8 kHz

Installation

Before installing, make sure the phone system has a message-on-hold or music-on-hold input, and that a non-switched 110 VAC outlet is near the unit. The box holds the DV-2000, a wall mount 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, flat, side or horizontal; 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 110 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

All connectors are on the front side. Connect the supplied RCA cable from LINE OUT to the message-on-hold input of the telephone equipment, and set the level with the audio output potentiometer. If that does not give enough level, move the cable to SPKR OUT.

• DC power: 2.5 mm barrel connector, 12 VDC; use only the AC-DC power adapter supplied by the manufacturer.
• LINE OUT (RCA): 600 Ω, transformer isolated, +4 dB line level output; connect it to the phone system first.
• SPKR OUT (RCA): amplified output, 2 W into 8 Ω (the Quikey gives up to 1.5 W), for on-hold circuits the line output cannot drive to a high enough level.

Loading messages from cassette

A new DV-2000 has a blank memory. To load a message, insert a recorded cassette, tape up and facing the label. The unit rewinds the cassette, plays it and records the audio program into memory, ignoring the silence before and after it. The red Record LED is on while audio is recorded. When the unit detects 5 seconds of silence, recording ends, the Record LED goes out and the tape is rewound; the 5 seconds of silence are deleted before the message plays.

The audio being recorded is sent to the LINE and SPKR outputs and can be heard on the monitor speaker. When recording is done, the DV-2000 plays the message automatically through the audio outputs, and the green M-O-H LED is on while a message plays. The Quikey recommends leaving the cassette in the system for autoload operation.

Inserting a tape deletes the previous recording immediately; if the tape is ejected before any audio is recorded, the memory stays empty.

Controls and indicators

• Eject / Record 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; pressing and holding for two seconds deletes the audio just recorded and ejects the tape without rewinding.
• Speaker pushbutton (black, locking): turns the front monitor speaker on and off. Its volume follows the audio output level; do not raise the output level to hear the monitor better, as that also changes the message-on-hold level.
• Tape Ejected LED (yellow): on when no tape is inside; goes out when a tape is loaded.
• Record LED (red): on while an audio program is recorded into memory; blinks once at power-on to show that the memory is operational.
• M-O-H LED (green): on while a recorded message plays.

Audio adjustments

Two potentiometers on the front, directly above the audio output connectors, tailor the output.

• Level: sets LINE OUT and SPKR OUT 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.

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.

Troubleshooting

• No LEDs on → normal just 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 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 and deletes the audio; check the tape side; a tape with no audio is ejected at its end.
• Nothing heard on the on-hold circuit → if both the Record and M-O-H LEDs are off, the unit outputs no audio; 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 → check the Record and M-O-H LEDs, lock the Speaker button down, and note that a very low output level also makes the monitor very quiet.
