  1)

 

Display 

      Shows the current DSP preset number. 

  2)

 

DSP mode control 

      Allows you to select DSP preset 1-16. The presets are divided in two groups, preset 1-8 are optimized  
      for using the LT-215A standalone (full range). Preset 9-16 are optimized for using the LT-215A in  
      combination with a LT218BA bass cabinet. Each group has 8 presets: Flat, indoor, outdoor, square,  
      grass, theatre, hall and user. If you own the optional interface and software, the LT-215A offers you the  
      ability to program/ edit your presets to your own specific requirements. 

  3)

 

LED array 

      

Power 

      Indicates that AC power is connected and the amplifier is turned on. 

      DSP limit 
  

    Indicates that the DSP protection circuitry is limiting the signal, thus preventing digital clipping. 

  

    Soft clip 

  

    Indicates that the analog soft clipping circuit in the poweramp section is active.  

      A soft clipping circuit clips short signal peaks in a way that is not sounding unpleasant to your ears.  
      Although a soft clipping circuit limits your dynamic range, it allows you to operate on higher volume  
      levels. 

      Protect 
      

Indicates an electrical or thermal fault condition in the power amp 

  4)

 

RS-485 Termination (only in older units) 

      Allows you to switch the RS-485 termination on or off. The last device in a RS-485 setup should always  
      have a termination resistor connected. If you’re using only one device in a RS-485 setup make sure  
      that the termination switch is pressed in.  

  5)

 

RS-485 control sockets 

      

Allows you to control one or more devices from the LT-series using your computer and the included 

      software. You can connect up to 32 devices. 

  6)

 

Input XLR input 

      The input equipped with 3 pole XLR/ jack combo socket is electronically balanced to accept the   
      (line) signal from any mixing console.

 

  7)

 

Link XLR output

  

      For linking several LT-series speakers.  

  8)

 

Volume 

      Use to adjust the input volume level for the LT-215A.

 

  9)

 

Ground Lift switch 

      When this button is pressed, it separates the signal ground from the chassis ground, enabling you to  
      eliminate potential ground loops or low-frequency hum. 

10)

 

Fuse Holder

 

      

Replace the fuse only with a fuse of same specifications (T8A).
