The Glensound HOWL32 is a high density frequency shifter for
preventing audio feedback across Dante and AES67 audio networks. It can
be fitted with a maximum of 4 independent frequency shifter cards. Each
of these cards provides 32 audio inputs and 32 frequeency shifted audio
outputs from the network.
There are no user controls on the HOWL32 as the frequency shift
function is preset - what comes in, goes back at less 5Hz. This
function means that if you route a mic audio input via the HOWL32, you
will significantly reduce the liklihood of acoustic feedback.
Every
frequency input has a 5Hz fixed offset for, example, 1 kHz in → 995 Hz
out. So the signal coming back to the mic is never at exactly the same
frequency as what left it. That means the system can’t 'lock onto' a
single resonant frequency and build a continous howl, as the potential
feedback frequency keeps reducing.
Being designed for 24/7 broadcast operation, each module on the
HOWL32 features redundant network interfaces. Both primary and
secondary network interfaces are available on copper Ethernet and SFP
module slots for fibre. Redundant power is available via dual AC IEC
connections.
Dante network audio is a common protocol for distributing high
quality linear audio over standard IP networks and it is widely used by
many audio equipment manufacturers. The Glensound HOWL32 Frequency
Shifter will be compatible with any other manufacturers' Dante audio
interface. Further details of Dante network audio can be found at
