INTRODUCTION 

Product Description 

The 

INO

mini

 

632

 is an FM and FM/HD Radio™ receiver for 

off-air broadcast monitoring.  It receives standard analog 

FM broadcast transmissions, as well as FM/HD Radio digital 

broadcasts transmitted via the FM station’s associated HD1 

through HD8 auxiliary, digital broadcasting channels. 
Analog FM and HD Radio digital programs are both accom-

panied  by  digitized  text  and  ‘housekeeping’  data.    FM  RDS  

(Radio  Data  System)  and  HD  Radio  PAD  (Program-

Associated Data) are shown on the front-panel LCD display 

of  the  632,  along  with  readouts  of  signal  quality  infor-

mation. 
When the 632 is set by the user to receive HD Radio digital 

broadcasts, it does not automatically revert to FM reception 

if the digital signal is lost.  Thus this receiver is not a suita-

ble radio for general consumer use. 

Product Features 

Features of the Inovonics 632 include: 

 

Reception  of  all  standard  FM  and  FM/HD  Radio  

broadcasts. 

 

Easy setup using the LCD screen and jog-wheel navi-

gation of the receiver’s menu tree. 

 

Front-panel display of most-essential FM RDS (Radio 

Data system) and HD Radio PAD (Program-Associated 

Data) information. 

 

Direct display of RT+ ‘tagging’ data. 

 

Analog L/R and AES-digital program line outputs. 

 

Front-panel alarms with rear-panel ‘tallies’ for Carrier 

Loss, Digital Program Loss and Audio Loss.
