Recording
Recording is possible from either the on-board microphone or external line in-
put. The input choice is selected by jumper position of J2. To select the Micro-
phone input, move the jumper to the “MIC IN” position as marked on the board.
The “LINE IN” position selects recording from a Line Level input from an exter-
nal source such as the Line Out of a cassette or CD player.
To record a voice message:
1. Set J2 to the “MIC IN” position.
2. Power up the unit by pushing in the power button.
3. Push the “Record” button S1. (The “Record” LED will illuminate.)***
4. Start speaking into the microphone.
5. Push the “Record” button a second time to release it and end recording.
To record from an external source:
1. Set J2 to the “LINE IN” position.
2. Connect the Line Level Output of the CD or tape player to the “Line Input”
jack J6 on the BS1. Potentiometer R2 adjusts the recording level and is typi-
cally set to about the “4 o’clock” position (as seen from looking over the
front panel.) DO NOT CONNECT SPEAKER LEVEL OUTPUTS TO THE
BS1 INPUTS OR DAMAGE TO U2 COULD RESULT!
3. Push the “Record” button on the BS1. (The “Record” LED will illuminate.)***
4. Start the playback of the CD or tape player.
5. Push the “Record” button a second time to release it and end recording.
*** If maximum memory capacity has been reached before releasing the
“Record” button, the “Record” LED will turn off indicating the unit has stopped
recording. Release the “Record” button at this time.
Recorded messages may be any length of time up to the maximum capacity of
8 minutes. Since the ISD4004 stores the recordings in a non-volatile memory,
there is no worry of losing a recording due to loss of power.
Playback
The BS1 has both a speaker level output (jack J4), for monitoring playback or
announcing to a local audience, and a set of Line Level outputs (jacks J1 and
J3) designed for connection to auxiliary equipment such as power amplifiers or
broadcast transmitters. The two Line Outputs are identical and serve only to
provide easier connections to units which require stereo (left and right) inputs.
