2. CONNECTIONS

2.1.

Connection Panel

The power and audio connections are located on the unique panel, shown in 2. The
different  parts  of  the  panel  are  explained  in  detail  in  the  following  sections  of  the
manual.

Control:

A) LCD

: Displays  information  about  the system status.  The  main  screen  shows  the

following information.

Current preset

Input Level

Output Level LF Channel

Output Level HF Channel

Amplifier temperature

ALC mode enabled/disabled

ECO mode enabled/disabled

Keypad locked/unlocked

B) KEYPAD

: Allows the user to perform basic operations on the DSP such as Preset

selection, audio settings and user preferences. There are three keys available:

MENU key:                OK key:               Circular key:

To enter  the  menu  the  keypad  must  be  unlocked  by  pressing  simultaneously  the
MENU and OK keys.
The central circle of the circular key will light up in blue when this key is active.

C) PROTECTION  LED:

This  led  lights  up  when  the  amplifier  is  in  a  protection

situation  (such  as  temperature  excess,  overcurrent,  or  other  situations  that  can
compromise  the  amplifier’s  integrity).  It  will  also  light  up  when  the  amplifier  is  in
standby mode. This happens for a couple of seconds at start-up.
The  Protection  led  will  light  off  when  the  amplifier  recovers  from  the  abnormal
situation.  Shall  the  Protection  led  keep  up  lighted  on  even  after  a  system  restart,
please contact an authorized service.

D) LIMITER  ON  LED:

The  limiter  led  lights  up  to  indicate  that  the  amplifier  is

delivering  the  maximum  power  set  by  the  limiter  circuit.  The  limiter  prevents  the
loudspeaker from receiving excessive or distorted signal. Continuous lightning of this
led  indicates  that  the  signal  is  being  massively  compressed.  In  this  case,  the  input
level should be reduced in order to get a proper dynamic headroom.
