Using the LIMITER for Basic Speaker Protection
In order to help you protect your speaker system, the
D3500 employs a digital Limiter. When engaged, the
digital Limiter will prevent signals from reaching outputs
levels over a desired point. The D3500’s Limiter has a vari-
able Threshold level, which is the point the limiter circuit
begins to attenuate the system. The Limiter also has a
variable Release time, which is the time the limiter circuit
takes to return the signal to the original level.
The LIMITER Switch Has Two Clicks!
