Whirlwind ISO2 User manual

ISO2
The ISO2 is a two-channel line level
isolation box and line balancer. Use it
to help eliminate hum and buzz
caused by long cable runs or to
convert unbalanced lines to balanced
in high noise environments.
XLR and 1/4" inputs accept balanced
or unbalanced connections.
Balanced XLR outputs each feature a
ground lift button.
Channel 2 features a handy polarity
reverse button to correct for opposite
polarity signals or mis-wired cables.
Whirlwind's premium TRSP-600
transformers ensure flat frequency
response and low distortion.
