How to set bridge mode of switching power amplifier?

Today we will introduce the bridge mode of our Sanway FP switching power amplifier.  Let's take FP10000Q for example.  Sanway FP10000Q is 1350Wx4 at 8 ohms; 2100Wx4 at 4 ohms; 2500Wx4 at 2 ohms; 4CH switching lightweight power amplifier.  When it is in bridge mode, its power is 2x4500W at 8 ohms bridge; 2x5000W at 4 ohms bridge. 

What is bridge mode of FP10000Q ?

Bridging refers to combining two (four) channels of an amplifier into one (two) channel(s) with twice the voltage. A two channel amp can be bridged to one channel, and a four channel amp into two channels. Bridging the channels increases the power output. An amplifier is usually bridged to combine two channels to power one subwoofer, or to combine four channels into powering two subwoofers 

What is the advantage of this mode ? 

It can help you to power the audio cabinet box with bigger power. 

How to use bridge mode of the audio amplifier?

Before  setting  the  mode,  please  turn  off the amplifier  and  slide  the mode  select  switch  to  above  ( Picture 2) ,  channel 1 and  channel  2 are  bridged,  channel 3 and channel 4  are  bridged. At  time,  the signal  input  into  channel  1  and  channel  3  will  be  output  from the bridge end.  On other hand,  the  output  level  control of channel  2 and  channel  4  should  be  turn  down  to  smallest .  Only  the  volume control  of  channel  1  and  channel 3 are  used to control the volume of whole system

Besides bridge mode, there is an parallel mode.  When you input signal from CH1, the output from CH1, CH2, CH3 and CH4 are the same.
