Several unique functions are available on all
inputs, such as the DF (adjustable damping
factor) and the Booster (increased gain at
50Hz).
DAMPING FACTOR
The Damping Factor can be set to HIGH [250] or
LOW [25] to drive any kind of speakers.
HIGH
Ideal match for big speakers with mid/low
sensitivity.
LOW
Suggested to drive high-sensitivity speakers and
mini- monitor as the IS-1000 acts more like a tube
amp.

BOOSTER
The Booster is a feature designed to reproduce the
lower range of frequencies with power and control.
It works as a custom equalisation, increasing the
gain around 50Hz to provide a richer and more
full-bodied sound. The 50Hz frequency has been
chosen since lower frequencies are more difficult to
obtain with small speakers.
The Booster is particularly useful in case of speakers
that require more energy in the bass frequencies,
for night-time listening at lower volumes, or even
to achieve a more realistic headroom with some
systems. The Booster is completely by-passed
when set to OFF, applied to 50% when set to 1,
applied to 100% when set to 2.
