Section II 

GETTING STARTED 

Unpacking and Inspection 

Immediately upon receipt of the NOVIA 236, inspect for 

possible shipping damage.  If damage is found or suspected, 

notify the carrier at once, and then contact Inovonics. 
We recommend that you set aside the original shipping car-

ton in the event that return for Warranty repair is required.  

Shipping damage sustained as a result of improper packing 

for return may invalidate the Warranty! 

Warranty Registration 

Please complete the Warranty Registration process.  Not on-

ly does registration assure coverage of the equipment under 

terms of the Warranty (printed inside the back cover of this 

manual), but the user is assured of receiving specific service 

and modification instructions, including software

 

or firm-

ware updates.  Register online at: 

www.inovonicsbroadcast.com/product-registration 

Mounting 

The NOVIA 236 is packaged in a compact, half-rack format.  

We  supply  stick-on  rubber  feet  so  the  unit  may  sit  on  a  

desktop or atop an existing piece of rack-mounted equip-

ment,  as  long  as  at  least  1U  of  panel  space  is  left  open  to  

access the NOVIA 236 front panel. 
An optional rack-mount kit is available that can accommo-

date a single or a pair of Inovonics half-rack products.  The 

kit comes with a blanking panel for unused space and with 

a ‘daisy-chain’ power cable so that two devices may share a 

single supply. 

AC Mains Power 

The  NOVIA  236  comes  with  a  ‘universal’  outboard  ‘brick’  

type switching power supply that accepts mains voltages 

between 100VAC and 240VAC.  The actual power consumed 

is  240mA  at  12  volts  DC.    A  second  DC  connector  on  the  

— 8 — 

rear panel of the unit allows the user to ‘daisy-chain’ two or 

more units to share a common mains supply, thus cutting 

down  on  cord  clutter.    Do  make  sure  that  the  total  power  

consumption does not exceed the DC current rating noted 

on the power supply label. 

Radio Frequency Interference (RFI) 

Although we anticipate the NOVIA 236 finding a home in 

radio broadcasting environments, please do practice rea-

sonable care in locating the unit away from 

abnormally

 high 

RF fields. 

Front-Panel Display and Controls 

LED bargraph meters monitor the processor input and out-

put.  These are peak-responding meters with a floating 

‘peak hold’ above the bouncing display. 
The input meter dB markings should be considered relative 

as the meter comes after the input level control in the signal 

path.  For the output meter, 0dB at the top of the scale cor-

responds to 100% carrier modulation.  
The input meter display range and activity will depend very 

much on the dynamics of the program material.  Heavily 

compressed music will generally peak (and ‘hang’) at about 

–6dB on the meter scale; material with greater dynamic 

range will show more variation. 
The green LED to the right of the level display indicates 

AGC gating.  It will be lighted most of the time, going dark 

only during pauses in speech.  The audio loss alarm lights 

the red LED. 
The front-panel OLED graphic display screen presents the 

setup/operate menu tree in an easy-to-read format, and all 

setup can be done with jog-wheel knob entry.  The display 

does employ a screen saver, so when the screen goes dim or 

completely dark, simply push the jog-wheel knob or 

Back

 

button once to bring the screen back to life.  No selection or 

change is made with this wake-up call. 

Front-Panel vs. Web Interface Setup 

The NOVIA 236 may be set up and operated either by using 

the front-panel menu and jog-wheel knob, or by using the 

Web interface.  Doubtless you’ll find the Web interface fast-
