er  and  easier,  but  we  do  advise  gaining  some  familiarity  

with  the  front-panel  approach.    You  will  need  to  set  up  a  

network connection initially from the front panel. 
Having  said  that,  if  you  are  adventurous  do  feel  free  to  

jump-in, set up a network connection and do all your setup 

over your network.  The Web interface is organized so much 

like the OLED Menu Tree that separate sets of instructions 

would be redundant.  Here in Section II we’ll concentrate on 

front-panel setup.  But anything in the Menu Tree can be 

found in the Web interface pages.  Check Section IV for mat-

ters that are specific to networking the NOVIA 236. 

Navigating the Menu Tree 

In a nutshell, you 

turn

 the jog-wheel knob to cycle among 

and to highlight menu items, and then 

push

 the knob to se-

lect, edit or adjust the highlighted item.  To further clarify: 

1)

 

If  you  land  on  a  menu  item  that  requires  a  text  or  

numerical entry, a text-entry screen appears when 

you enter that submenu.  

Turn

 and 

push

 the knob to 

select  alphanumerics,  punctuation,  backspace,  etc.  

After text entry, select 

Save

 and 

push

  the  knob  to  

commit to entry, or press the 

Back

 button next to the 

knob to cancel the operation. 

2)

 

If  the  submenu  has  a  checkbox  or  ‘radio  button,’  

bracket the option and 

push

 the knob to toggle it. 

3)

 

If the screen shows an adjustment ‘slider,’ 

turn

 the 

knob to bracket the slider, 

push 

the knob to enable 

adjustment, and then 

turn 

it to change the value.  Fi-

nally, 

push

  the  knob  or  press  the  

Back

 button  to 

commit to the adjustment. 

You  may  always  press 

the 

Back

 button repeat-

edly  to return  to the 

Main Menu screen shown 

here. 

Analog and Digital Program Inputs 

As one might well expect, the rear-panel 

ANALOG IN

 XLR 

connector accepts only a single channel of program audio.  

But the stereo-capable 

AES IN

 digital input may be config-

— 10 — 

ured as required, offering ‘split’ use of the channels to feed 

a separate program to a co-located service. 
From  the  Main  Menu, 

navigate to

 Setup

/

Inputs

Digital Input Mono Mode

.  

This is where you select 

your AES-digital pro-

gram feed, either from internal combining of 

 Left

 

+

 

Right 

stereo channels, or for input audio from 

only

 the 

 Left 

or 

only

 the 

 Right

 channel of the AES-digital stereo pair. 

Stream Input 

Just as described for the AES-digital input, The NOVIA 236 

can accept monaural or stereo streamed audio.  Navigate to 

Setup

+

 

Right 

stereo feed, or for input audio from 

only

 the  

 Left 

or 

only

 the 

 Right

 streamed channel. 

Under 

Stream URL

, man-

ually enter the Internet 

address of the streamed 

program  audio  source.  

When the 

 Only connect 

when stream is source

 box is 

not

 checked, the NOVIA 236 will 

connect to a valid stream automatically and remain con-

nected.  When the 

 Only connect when stream is source

 box 

is 

checked, as shown above, the unit will connect to the 

stream either when the stream has been manually selected 

as the primary input source or ‘failover’ has switched-over 

to  the  stream  as  the  backup  source.    The  

Connect

 button 

simply forces a re-connection. 

Input Sources and Program Failover 

From the Main Menu, go to 

Input Sources 

to select your
