  OPERATION  Instruction notes 

·   USE  Only  one set of inputs at a time  either  LOW  or  High
  LEVEL- not both 

·   LOW input: Bridge  both L& R Low level inputs if you have a mono output from your DVD or Home Theatre Amplifier this will give a 6db volume Level boost.

·  HIGH input : separate  L&R  speaker cable feeds from L&R front speakers to the  High level inputs on Sub Amp for Home theatre or Music DVD # Double check the polarity of the speaker leads is correct before switch on . 

·  PWR / PRT : LED light  normal mode  Green , 
 Protection mode LED changes to RED

·  Use Phase switch REV /NORM to achieve the deepest bass in sync with the L&R Front 
 Speakers 

·  Delayed Power on takes 5 to 20seconds  this is the Speaker  anti thump circuit  protecting the speaker on initial switch on 

·  Subwoofer Level Frequency and phase  controls are to achieve the best sound from your Subwoofer speaker  in conjunction with the Subwoofer speaker room  position .This will vary radically with different rooms and different program material music requiring different settings of the Gain/Freq/Phase  Controls  DVD movies require different settings to DVD music or CD Music
