Using your Audibox
The simplest ideas are usually the
best!
The Optimizer is a unique trans-
former isolated Level optimizer.
An accurately calibrated Level con-
trol sits between the Jack and RCA
Inputs and Outputs, enabling precise
level attenuation and matching.
It allows you to attenuate the level
from one piece of equipment to the
next in order to provide the exact
level required and reduce the risk
of overloading sensitive inputs, es-
pecially ones on the front of digital
converters.
The internal Iso Transformer pro-
vides hum prevention and complete
Galvanic isolation for this essential
piece of equipment for anyone
needing accurate level matching, eg.
Live audio feeds, digitising audio and
more. It will have applications in Live
Sound, Studio or Broadcast use.
Power Requirements
None. The ISO Optimizer is a pas-
sive iso-transformer coupled devic-
es,
ie.
it doesn't need power to run,
making it a truly universal problem
solver.
The heavy duty all-steel chassis is fin-
ished in attractive matt textured
powdercoat, with hardwearing
epoxy screen printing and slip resist-
ant rubber pads.
Specifications
Security features include Kensing-
ton®-type computer lock slot and
optional bracket kit for under-table
mounting.
Please note that it is advisable to pow-
er down the system before connect-
ing it, to avoid the risk of sending large
electrical and signal noises through the
system when disconnecting and con-
necting.
