- Page 2 Technical Specifications: Power Input: 4‐12V Output: 0.3mW @ 4ohms (if input is <6V) or 0.5W @ 8ohms Dimensions: 65(L) x 35(W) x 20(H) mm Notes: Never get any part of the module wet. Never attempt to open, modify or repair any part of the module. Instructions: Test the unit first before installing: Connect a 9V power supply to the amplifier module, with a multimeter (switched to the 200mA range) in series with one of the leads. Do not connect to a loudspeaker yet. With no input signal, you should get a quiescent current of about 8‐10mA. Any more than this and you should switch it off immediately. If everything appears to be okay, connect a loudspeaker and perform a ‘blurt’ test. To do so, turn the volume up high and then put your finger on the input audio signal. This will inject a hum/hash signal into the amplifier which is heard as a ‘blurt’ from the speaker. If it blurts, it is working fine. ...
