User manual OMNICRON ELECTRONICS ANALOG RECORDERS (VLR)-PAGE 2

[. . . ] The VLR-4 and VLR-8 recorders include slow speed drive circuitry. The VLR-4 provides up to four hours of recording time on each side of a tape. The VLR-8 provides up to 8 hours per side. Automatic level control recording assures the best performance with reduced back-ground noise and distortion. [. . . ] Depress this key a second time to EJECT the cassette. If you reach the end of the tape while recording, the recorder will shut off and the PLAY and RECORD buttons will pop up. RECORDING FROM OTHER SOURCES: RADIO, PHONE, ETC. Your recorder receives audio either by placing a microphone near the speaker of your audio source, or by connecting directly to the speaker or audio output of the device you wish to monitor. If possible, use a direct connection to prevent unnecessary noise pickup. A direct connection also will produce clearer recordings. Most telephone and some twoway radio installations require the use of an interface coupler or adapter (such as the TSA-3, LIC-390, or LIC-100) between the recorder and the audio circuit. Couplers provide isolation and a balanced line input. They also help to prevent the noise on telephone lines from reaching the recorder between conversations. Check with your Omnicron dealer or telephone company to see if you require a coupler for your application. Do not connect the recorder directly to telephone lines without a coupler. Improper operation of both your recorder and the telephone circuit could result. An accessory patch cord is available (AUX-6S) for use if you will be connecting the recorder to your audio source without a coupler. It will also beep if you do not place the unit back into the auto-record mode after reviewing a recording. To deactivate the alarm, use a small screwdriver to place the switch into the OFF position. DO NOT FORCE THE SWITCH. ALC SWITCH On recorders that do not have the CT option (Clock Track) there is a switch to turn off the Automatic Level Control. You should normally set this switch to the ON position. If you set it to the OFF position, the internal ALC circuit will be off and the recorder will not automatically adjust for sounds that are too loud. Use the record level adjustment on the bottom of the recorder to set the recording level. When the ALC switch is on, you must still turn the record level up if the sound is too weak and the record level light does not flash while recording. The ALC circuit will prevent sounds that are too loud from over driving the recorder. On recorders with the Clock Track option, this switch is used to select the time track during playback. PLAYBACK Insert a recorded cassette with the full reel to the left and the side you wish to play up. If the cassette you are playing was just recorded and is still in the recorder, rewind it to the beginning of the recording. Then set the volume for the desired listening level from the speaker. [. . . ] When playing back the recorded conversations, simply switch to the Time Track and you will know exactly when that moment of conversation was recorded. One Talking Clock can provide time and date announcements for over 50 recorders. OMNICRON recorders are used in a wide variety of voice logging applications. A standard or custom audio adapter, coupler, or cable should be be ordered with the recorder to match your audio source. [. . . ]
