[. . . ] This feature minimizes false recordings and does not apply when using Voice Activated Recording (VAR). This feature can be disabled from the Recorder Settings menu. a. Setting for Phone Line or Voice Activated Recording (VAR) When you first connect a new TeleCorder, default settings for all channels will be for Voice Activated Recording (VAR). Channels connected to phone lines should have their start/stop mode changed to the voltage sensing start/stop mode. In this mode, instead of monitoring audio levels, the recorder will monitor for DC voltages on the selected inputs to indicate on-hook and off-hook status. The phone line voltage is high when the circuit is not in use and will drop to a lower voltage when it is being used. Any channels set for on-hook/off-hook voltage sensing that are not connected to a phone line will not show any recordings due to the lack of the DC voltage changes that are required to initiate a recording. If you connect any of the TeleCorder inputs to audio sources that do not have standard on-hook/offhook voltages, these channels must be set for voice activated recording (VAR). b. VAR Settings Recorder channels set for the VAR mode will detect the audio level on the channel (port) input to start a recording. It will start recording when a preset audio level is reached (normal conversation levels), and stop after the audio drops below this threshold (no sound other than weak background noise) for a preset period of time. The length of quiet required for the recording to end is called "turn-off-delay". Phone Line Recording Requirement to Start Requirement to Stop Phone Line DC voltage lower than the threshold, o/a 20v DC Phone Line DC voltage higher than the threshold, o/a 20v DC Recording from standard analog phone lines Suggested Uses Voice Activated Recording (VAR) Audio level on input is loud enough or louder than preset threshold required to start recording Audio level is lower than preset level required to continue recording for the selected turn-off-delay 1 Radio recording, broadcast or two-way 2 Meeting recording with amplified microphone 3 Audio picked up from handset or headset of analog or digital telephone set (single or multiline phone) 4 Analog phone line recording where DC voltage sensing cannot be used 5 Paging and Intercom audio User Manual -- TeleCorder with UpCorder Software -- V 2. 02-B-US 9 Parameters 1. VAR TimeOut: If any channels have VAR selected for start/stop, set the TimeOut to one of the four choices; 20, 40, 60 or 120 minutes. This setting will limit the maximum length of a recording for easier management of long conversations or for when recording from broadcast radio where pauses may not be long enough to separate individual recordings using VAR for start/stop. If a recording reaches the maximum length of time that you select for VAR TimeOut, that recording will end, and a new recording on that channel will begin. Click the Write Hardware button to confirm any changes. This setting is only for recordings using VAR. It does not limit length of recordings when using voltage sensing for start/stop. Time and Date Setting: Date and time are supplied by the clock in your PC. Audio Recording Modes: From this sub-button you can set the quality of recordings. 8bit linear PCM mode used in the 1st generation recorders. Caller ID Detection Settings: From this sub-button you can set (turn on/off) the Caller ID detection features. Pre-Ring DTMF Detection: If the local Caller ID mode is DTMF and sent before the ring, you must turn this feature on. [. . . ] It has an RJ-11 jack on one end and a 3. 5mm monaural mini-plug on the other end. The MOD-SC is typically used to connect modular telephone line cables used with audio recorders to the audio output of a radio receiver that uses a 3. 5mm jack for speaker or line level audio output. MTJ-S2 -- Converts a 2-Line RJ-14 Modular Telephone Jack into Separate RJ-11 Single Line Jacks This adapter/cable assembly splits a 2-line RJ-14 circuit/jack into two RJ-11 jacks (Line-1 on left and Line-2 on right). It is typically used with the two line jacks on the TeleCorder and other Voice Logging Recorders that have two inputs on a single modular jack (RJ-14, 6P4C). PZ-2LA -- Pressure Zone Room Monitoring Microphone with Line Level Output The Omnicron PZ-2LA Microphones are Pressure Zone Microphones designed for meeting and conference recording. They look like a switch, not a microphone, so as not to draw attention. [. . . ]
