Omnicron Electronics - Professional Voice Logging Recorders and Accessories - since 1975



The "VP" series of cassette tape players are designed to play back the recordings made on the "VLR" and "CR" series of Omnicron Voice Logging Recorders. They provide an inexpensive means of playing the tapes without tying up the main recorder/player. Since they do not have the ability to make recordings, accidental erasure is not possible.

See the chart below to insure that your tape player matches the speed of your recorder and has the time track if your recorder has a time channel.

If your player has the Time Track (CT) option, there is a rocker switch located on the front of the unit under the volume control. When playing tapes, you can select either the main "VOICE TRACK" or the "TIME TRACK". If the tape you are playing has verbal time or time and date announcements recorded on the edge of the tape, you will hear the time announcements with the switch in the "TIME TRACK" or down position. Switch back to the "VOICE TRACK" or up position to play conversations recorded on the main channel.

This manual covers the following Omnicron "VP" Models -



Standard 1-7/8 ips NO VLR-1 or CR-1 (std. spd.)
VP-1CT Standard 1-7/8 ips YES VLR-1CT

Setting up your player

Installing batteries
Remove battery compartment cover (located on bottom of unit). Insert six "C" size batteries in compartment; alkaline type batteries are recommended for longer life and maximum power output. Carefully follow polarity (+ and - symbols) diagram inside case.

After batteries are installed and seated correctly, replace compartment cover. NOTE: Always remove old or weak batteries immediately to prevent damage due to leakage. Batteries should be removed if player is not used for an extended period of time.

Operating on AC current
This player may be operated on regular 120 volt 60 Hz AC current. The 1.7 meter AC cord fits snugly within open storage compartment on bottom of unit. Plug cord into a properly grounded wall outlet. This automatically disconnects battery circuit. The three-prong plug should be used without a two-prong adapter whenever possible. If an adapter is used, be certain the green wire or grounding tab on the adapter is attached to the screw on the wall outlet plate for proper grounding.

CAUTION: If it is necessary to use a power cord adapter, have a trained electrician install the adapter to the outlet and check wiring to be sure there is no shock hazard. Faulty wiring can cause damage to the unit and possible injury to the operator.


Using your player

Playing a recorded cassette
After setting up your player by installing batteries or by plugging in the AC power cord, you can play recorded cassettes by following these easy steps.

1. Open Cassette Chamber cover by pressing down Stop/Eject key. Insert cassette into channel rail inside chamber cover with exposed edge of tape facing you and full reel to your left. If you are playing a commercially recorded cassette, selections listed on the label on top side are the ones that will be played.

2. With cassette seated, close cover of cassette chamber and press Play key to listen to the tape.

3. If your player is a "CT" version, select either the main voice channel or the time channel with the "VOICE-TRACK/TIME-TRACK" rocker switch located on the front of the recorder. If the tape you are playing has verbal time or time and date announcements recorded on the edge of the tape, you will hear the time announcements when this switch is in the down position. Switch to the up position to play audio which was recorded on the main channel.

4. Adjust Volume Control and Tone Control for comfortable listening level.

Most tape cassettes have two sides. Pre-recorded cassettes are normally recorded on both sides.

Your player has a Full Automatic Shut-off feature which turns the unit "off " when all of the tape on one side has been played. To hear selections on the other side, just turn cassette over and reload as explained above. The full reel of the cassette should always be on your left when loading.

Using Review and Cue keys
After playing a tape and with the tape stopped, pressing Review key or Cue key will lock the key down for fast rewind or fast forward, respectively. Pressing Stop key returns Review or Cue key to up position.

For a quick review, back up the tape by pressing Review key (leaving Play key down) and hold it for the desired time. When Review key is released, unit returns to play mode.

To advance tape to another selection, press Cue key (leaving Play key down) and hold it for desired time. When Cue key is released, unit returns to play mode.

When using Review key and Cue key, you soon learn to estimate approximately how long to hold the key depressed to reach a desired tape location.

Using Pause key
The Pause key is used to instantly stop the tape transport without releasing the Play key. Push this key once to stop tape movement; push it again to restart tape.

Using tape counter
The counter provides a means of numerically indexing selections on tape cassettes and allows fast return to specific parts of the tape. To reset counter to "000" at the start of tape, press reset button. The counter conforms to 2X ANSI standards.

Using Listening Center
Located on top of the unit, this center consists of four standard 1/4" headphone jacks. From one to four headphone sets may be plugged into this center at one time for private group listening of tape cassette being played.

NOTE: When using more than one headphone, be sure that all headphones are of the same type or impedance so that they will all reproduce at the same volume level. The 1/4" jacks are not designed to operate extension loudspeakers.
