STATUS LEDs

On the front of your speaker, you can see a front LED 

panel which will indicate its operational status in the fol-

lowing way:

•  Red “OL”: lights up if the limiter circuit of the speaker 

kicks in and protects the drivers from overloading

•  Green “PWR / STBY”: normal operational power-on 

status

•  White “SYNC”: lights up if the speaker is synchronized 

with a digital source (HEDD Bridge card) 

 

HEDD BrIDgE

The HEDD Bridge was inspired by the rather simple and 

yet absolutely vital idea that our analog speakers should 

feature a freely configurable system that, being located 

on the back panel of each monitor, allows for the optional 

integration of specific digital audio protocols. The HEDD 

Bridge is nothing less than a modular system of input 

cards that enables all HEDD monitors to fully handle 

digital protocols such as USB2, AES3, Wireless and even 

AES67 / Dante, that is Audio-over-IP. As a customer you 

can either stay completely in the analog domain or can 

choose the HEDD input module that fits your workflow 

and audio environment in the best possible way.

The HEDD Bridge brings versatile digital input connectiv-

ity including two AoIP options to the world of professional 

monitoring. For the first time, it becomes possible for 

studio monitors to be integrated into today’s most es-

tablished audio network protocols: Audinate’s Dante and 

Ravenna Network / AES67.

Here are a few examples of how loudspeakers can be used 

in an AoIP environment:

•  Directly connect a computer to the loudspeakers via a 

CAT.6 Ethernet cable and stream high resolution audio 

•  In complex multi-channel setups (like Dolby Atmos, 

Auro 3D), multiple separate loudspeakers can be fed 

with a single high-resolution audio stream and each one 

of these speaker channels can be controlled individually 

by software control applications 

•  Audio devices in different rooms or facilities (e.g. movie 

theaters, conference rooms, live concerts and music 

festivals) can be controlled from one or multiple work-

spaces connected to the Ethernet network 

•  AoIP will enable broadcast engineers to simplify the in-

house signal distribution in broadcast stations
