GENERAL
OMNICRON "VLR" recorders are professional analog voice loggers designed to provide you with complete documentation of your important telephone conversations, two-way radio messages, or dictation. They have special features which allow virtually unlimited use in a wide range of applications, with top performance and minimal maintenance.
            Built-in voice activation circuitry expands the recording time by automatically stopping the recorder between conversations. Model VLR-1 runs at the standard cassette speed allowing you to record and playback tapes which are compatible with recorders that do not have slow speed capability.
            Advanced slow speed drive circuits in the VLR-4 and VLR-8 recorders expand the recording time even further to provide 8 or 16 hours of solid talk time on each cassette tape. The VLR-4 provides four times the unattended recording and playback time. It packs 8 hours of conversation on each MLC-120 cassette tape. The super slow speed VLR-8 runs at 1/8 speed for 16 hours per tape with little loss of fidelity (8 hours per side with an MLC-120 cassette).
            VLR recorders which have the "CT" Clock Track option (VLR-1CT, VLR-4CT, and VLR-8CT) are designed for use with the Omnicron TCC-14 Talking Clock/Calendar. They have a second track for recording the verbal time and date announcements provided by the clock. When playing back the recorded conversations, simply switch to the Time Track and you will know exactly when the recording was made. One Talking Clock can provide time and date announcements for over 50 recorders.
 

FEATURES
DESIGNED FOR CONTINUOUS DISPATCH CENTER USE
VOICE ACTIVATED RECORDING — with adjustable record level, activate-sensitivity, and turn-off delay.
ALARM — beeps when the cassette needs to be changed, or if the recorder is turned off either accidentally or by  the built-in all mode motion sensing circuit. The tape drive automatically turns off and sounds the alarm if the tape stops when it should be moving in record, play, fast-forward, or fast-rewind.
MONITOR WHILE RECORDING — lets you listen to conversations while they are being recorded, through the built-in speaker, through either of the two 1/4" headphone jacks, or through the 1/4" external speaker jack (8 Ohm).
CUE AND REVIEW — for rapidly finding and repeating recorded messages.
AUTOMATIC RECORD LEVEL CONTROL — prevents overload on strong signals. Manually adjustable record level, activate-sensitivity, and turn-off delay permit you to adjust the recorder’s voice-activation circuit to match your particular application.
AUTOMATIC END-OF-TAPE SHUT-OFF — in record, play, fast-forward, and fast-rewind.
TAPE SIZE — Standard Compact Audio Cassette.
AUTOMATIC BATTERY CHARGING — for optional rechargeable batteries, unit automatically switches to battery power if external AC power is lost.
MONITOR & ALARM ON/OFF SWITCHES
INPUT/OUTPUT JACKS — auxiliary audio input, microphone, remote record on/off, remote speaker, two headphone jacks, and Talking Time Clock (CT option only).
ROTARY VOLUME & TONE CONTROLS
DIGITAL TAPE POSITION COUNTER WITH RESET
AC BIAS RECORDING — for optimum voice frequency recordings.
EASILY INSTALLED — with or without direct electrical connection.
