MXA118 80 SECOND VOICE RECORDER WITH 5 WATT AMPLIFIER

This circuit is a Digital Audio Recorder and low consumtion current when
standby about 128µA. It can use the battery for supply the circuit. This circuit can be
connected MXA119 PIR sensor for giving the word “Thank you”. If connect with
MXA112 infrared sensor, user have to use the adaptor 5VDC to supply the circuit.
TECHNICAL DATA- Power supply : 5-6VDC.- Consumtion : 128µA (standby), 250mA (working) at speaker 8-ohm 0.25W.- It can be connected the external sensors for starting the operation of circuit.- Build-in on-board audio power amplifier 5 watts.- Can select external sources for recording.- PCB dimensions : 3.55 in x 2.12 in.
CONNECTING POINTS FOR APPLICATION- +5V- point is for connecting to a 5-6VDC power supply.- SP1 and SP2 points are for connecting to speaker 8-ohm 0.25-3.0W.- SW1 switch is for playing the message and pause the message.- SW2 switch is for selecting the play mode (PLAY) and the record mode
(REC).- J1 jumper is used to select the operation of circuit. If connected to J1 and
supply the power, the circuit will run continuously. If not connected to J1, the circuit
works when SW1 is pressed or receives an external signal.- I/P SENSOR point is used to connect the sensor PIR, Coin acceptor and
Switch, etc.- LINE IN point is used to connect the external sound for recording.- JM1 and JM2 jumpers are used to select the source sound when the circuit is
recording. If connected to MIC point, it’s a recording of the microphone. If
connected to IN point, it’s a recording of LINE IN point.- SMP point is used to adjust the quality of recording sound. If adjust to the
rightmost, the sound quality is low and the recording range is 80 seconds. But to the left,
the sound quality is high and the range is 50 seconds.- VOL point is used to adjust the sound level of playback
