Chapter 3 

Starting up and operation 

 

3.1 Basic  actions 

3.1.1  Processing programs 

562dsp  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” 

3.1.2  Modes of control 

The processor can be controlled of many ways: 

a)

  Can  be  manually  controlled  from  the  frontal 

panel.  

b) 

Connecting

 

the  unit  to  a  PC,  you  can  create 

and 

edit 

programs 

using 

the 

562dsp 

VirtualRack software

. This software allows to 

save the 562’s programs in the Hard Disk (files 
.562)  that  you  can  send  by  mail,  so  that  other 
radios that you manages share the customized 
adjustments.  In  addition;  this  software  allows 
creating  a 

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.

  

 

In  this  modality  the  programs  can  be  chosen 
automatically  from  the  OnAir  PC,  using  the 
automation  software 

Solidyne  Audicom  7

This way you can use a specific processing for 
each musical style.  

 c) 

Models

  562dsp/IP

  allows 

direct  connection 

to  the  LAN

.  You  can  run  the  software 

VirtualRack from another terminal to control the 
562dsp/IP. 

 

With  the  apropiate  network  configuration,  you 
can adjust the sound of the radio in real time... 
from  your  Laptop,  while  drinking  a  cup  of 
coffee at the living room of your home; listening 
you  favorite  audio  system,  which  sound  you 
know very well. 

 

By the other hand, this feature allows to asjust 
the  processing  from  far  distances,  to  optimize 
the reception in areas  with marginal coverage. 
Please see “2.9 – Ethernet connection”  

 

3.1.3  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. 

 

3.1.4  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”.
