SOLIDYNE 462

dsp - broadcast digital processor

 

This  option  is 

disabled  from  factory

  (program 

30:Mic processing off). In order to enable it, select 
“Mic  processing  PGM”  and  choose  a  program 
created  for  voices  (for  example  09:VOICE 
IMPACT). 

The commutation controls from a connector in the 
rear panel, detailed in the installation chapter (see 
“2,5 Console MIC Start”). 

 

 

TIPS 

The 

programs for “music” and “voice” do not have to be 

radically  different

.  The  gains  of  the  density  EQ  and  the 

AGC  output  must  stay  without  greater  variations.  The 
differences  will be fundamentally in the  attack  and recovery 
times of the AGC and the multiband compressor.  

It  agrees  to  create  the  adjustment  for  voices  starting  from 
the  adjustment  chosen  for  music.  The  attack  and  recovery 
times used for music usually are slower than those required 
for the voices, mainly in the AGC. Observe and compare the 
factory presets. 

 

 

PASSWORD:

 You can define a password to avoid 

the access of unauthorized personnel to the main 
menu  to  change  the  settings.  Once  defined, 
462dsp will ask for the password whenever you try 
to  accede  to  the  main  menu,  but  you  don’t  need 
the  password  to  explore  the  program  list  and 
change the program on-air. 

The  password  must  have  3  characters.  Any 
combination  of letters,  numbers  and  symbols  can 
be used. 

  To enter a password, go to field “Password” turning 

the JOG and touch it briefly to confirm.  

  A flashing cursor appears to enter the first character. 

Turn  the  JOG  until  reach  the  wanted  symbol  and 
confirm with brief touch. The cursor will jump to the 
next character. 

  Proceed  in  the  same  way  to  choose  the  others 

characters. 

  After  confirm  the  last  character,  the  option  “OK”  is 

on  focus.  PRESS  AND  HOLD  to  confirm  the 
password. A brief touch in this point will make jump 
the cursor to the first character again. 

 

Press  and  hold  the  JOG  cancels  the  process

  in 

any  instance.  (equivalent  to  escape), 

except  when 

“OK”  is  selected

,  in  such  case  confirm  the 

password!

 

  To 

delete  the  password

,  edit  it  entering  3  space 

characters.

 

 

 

 

Write down the password in a secure place, in 
order to do not loose it. If you forgot the 
password, please contact with Solidyne; and y 
you will receive instructions to restore it. 

 

PROCESSOR  MODE:

  Shows  the  processor  type. 

The  unit  can  be  prepared  for  FM  or  AM  stations. 
This  is  defined  in factory,  because  requires  some 
internal  changes  in  the circuit  board;  as  well  as  a 
different  programming  of  the  flash  memory  with 
the corresponding constants for the AM band.
