Description
SPEAKER PROTECTOR :
The Speaker Protector is designed to prevent damaging low frequencies from reaching automotive midrange and high frequency drive units. It improves sound quality by lowering distortion levels.
PURPOSE:
The Speaker Protection Circuit has two main functions:
1. To protect the audio amplifier and the loudspeakers during start-up sequence when the amplifier output might exhibit DC voltage.
2. To protect the loudspeakers in the unlikely event of an amplifier power stage failure, where DC component would damage the
speaker voice coil.
speaker voice coil.
POWER INPUT :
The Speaker Protection Circuit can be powered with AC voltage in range of 12V AC, 50Hz and requires about 40mA for proper operation. This is a very small current which can be obtained from an auxiliary winding of any transformer.
HOW IT WORKS:
The Speaker Protection Circuit will disconnect the RELAY, if a DC voltage is present. Delayed Startup will protect loudspeakers during start-up sequence when, the amplifier output might exhibit DC voltage.
HOW TO CONNECT:
1. Connect 0-12 V AC (no polarity) to power on the board.
2. Left + and Right + from power amplifier should be connected to amp in L+ and R+ input vise versa.
3. Connect L+ and R+ out from speaker protection, to the speakers.
4. Connect Left – and Right – from power amplifier directly to speakers.
