AFW 30

ANTI-FEEDBACK WORKSTATION

EQUALIZER, PEAK LIMITER, SABINE FBX FEEDBACK SUPPRESSION

Tuning and calibrating an audio system,
whether it’s for a conference or a concert,
is a complex procedure at the best of times!
Simply stopping feedback is only a part of
it - you still need to adjust the actual fre-
quency response of the system in the room.
In the ideal world you’d have an equalizer
to set the system EQ curve, something to
eliminate feedback, and something else to
keep the system level under control.

So, we’d like to introduce you to the ARX
contribution to the ideal world - the ARX

AFW 30 Anti Feedback Workstation.

A super accurate 30 band graphic equaliz-
er, with 30 of our new

XR Extended Res-

olution

long throw faders providing up to

± 10dB of cut and boost, a fast, smooth
sounding peak limiter, plus onboard 9 band
FBX Feedback Exterminator DSP circuitry
licensed from Sabine.

The first 6 FBX filters lock in at the primary
feedback nodes, leaving 3 filters ‘floating’
to handle any short term feedback prob-
lems, such as presenters or artists moving
the microphone in front of the speakers, or
too close to monitors, or something simi-
lar. These are usually short term problems,
and once they have passed, the floating
filters go back to a waiting mode.

Operation of the

AFW 30

is simplicity

itself. Just use the EQ section to set
the curve you require, press the Re-
set switch in the anti feedback section
for 4 seconds, and start increasing the
system gain.

If the system is in a fixed installation,
simply power everything down when
you’ve finished. The

AFW 30

remem-

bers your anti-feedback settings next
time it is used - there’s no need to re-
set the circuit when it is turned back
on.
The

AFW 30

also features a Variable

Threshold Output Limiter to ensure
freedom from System overload and
Amplifier clipping.

The ARX

AFW 30 Anti Feedback

Workstation

has an application for

every mode of live and installed au-
dio: Monitors, Front of House, Church
installations, TV audience monitors,
Conferences.
In fact, anywhere there’s a live micro-
phone and loudspeakers, there’s a
need for the
