Starting up and operation 

 

 

3.1 Basic  actions 

3.1.1  Using the JOG wheel 

All the installation settings and each parameter of 
audio  processing  are  managed  with  the  JOG 
wheel into a friendly graphic interface. 

The frontal panel presents a big blue screen of dot 
matrix,  and  a  rotating  control  (JOG)  with  push 
button. Their use is very simple: 

  Turn  the  JOG  control  to  select  an  option  or  to 

change  values  (i.e.:  changing  levels;  select 
Yes/No; etc.) 

  To  confirm  an  option/value 

press  the  JOG 

briefly

. It’s like make “click” with the mouse. 

 

Push and hold the JOG by a second

 to enter 

to the Main Menu or to cancel a screen. It’s the 
equivalent to double-click with a mouse. 

3.1.2  Processing programs 

462dsp  has 

15  presets

  programs  and 

15  user

 

memories.  Programs  from  00  to  14  are  programs 
made  by  the  engineers  of  Solidyne, 

ready  to  be 

on  the  air

.  There  are  different  adjustments  for 

different music’s styles. Each program has a name 
that  identifies  it  (Jazz,  Rock,  Pop,  Melodic,  etc.) 
but  the 

names  are  only  indicatives

;  all  music 

styles  sounds  well  with  any  preset.  Processing 
programs are described with detail later. 

You can customize the programs copying it to the 
user  banks  (15  to  29)  and  edit  them.  By  default, 
user  memories  are  “empty”  (strictly  speaking  with 
“flat”  processing  adjustments).  You  can  create  a 
new  adjustment  changing  the  values  of  each 
parameter  on  the  user  memory;  or  copying  a 
preset  to  the  user  memory  (recommended).  See 
“4.3.1 – Copy programs” 

3.1.3  Modes of control 

The processor can be controlled of many ways: 

a)

  Can  be  manually  controlled  from  the  frontal 

panel.  

b)

  The  programs  can  be  chosen  automatically 

from  the  OnAir PC.  In this  way  you  can  use  a 

specific  processing  for  each  song  or  musical 
style.  

c) 

The programs can be created and edited using 
the 

462dsp  VirtualRack  software

.  This 

software  allows  saving  the  462’s  programs  in 
the Hard Disk (files .462) that you can send by 
mail,  so  that  other  radios  of  your  chain  share 
the  customized  adjustments.  In  addition;  this 
software 

allows 

creating 

scheduling 

programming

,  to  change  the  processing 

program  at  certain  hours  from  the  day.  Virtual 
Rack  runs  in  background  using  very  few 
resources.  In fact  this  software  can  run  on  the 
On-Air computer.

  

d) 

Connecting

 

the  PC  to  Internet,  you  can 

controls  the  software  via  “Shared  desktop” 
Windows feature. 

 

 

3.1.4  Access password 

You  can  define  a  password  of  3  characters 
(letters,  numbers  and  signs)  to  avoid  that  non 
authorized  people  make  changes  on  the 
programming adjustments. 

Each time that you try to access to the main menu 
the processor will ask you for the password. 

Note  that 

you  don’t  need  the  password  to 

change  the  current  preset  on-air

.  Please  see 

“3.2.3 - Processor Setup”. 

 

3.2 INSTALLATION SETTIN GS 

 

a) 

On  start  up,  the  462dsp  shows  by  a  few 

seconds  the  boot  screen  indicating  the  firmware 
version.  Once  started;  the  processor  present  the 
main  screen;  described  in  the  item  3  of  the 
Chapter 1.  

 

The unit always starts loading the last used 
program.

 

 

b)

  Pressing  and  holding  the  JOG  you  accede  to 

the 

Main Menu.
