Authorities in our business will tell in no uncertain terms that Lorem Ipsum is that huge, huge no no to forswear forever. Not so fast, I’d say, there are some redeeming factors in favor of greeking text, as its use is merely the symptom of a worse problem to take into consideration.

Product care

Anyway, you still use Lorem Ipsum and rightly so, as it will always have a place in the web workers toolbox, as things happen, not always the way you like it, not always in the preferred order.

Product details

Made possible by exploring innovative molded plywood techniques, Iskos-Berlin’s Soft Edge Chair blends strong curves with extreme lightness to create a three-dimensionality not usually possible with 2-D plywood.

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.
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.
