Installation

Technical Considerations:

When a loudspeaker EQ is selected in ControlSpace Designer, the appropriate crossover and V

and V

RMS

limiters for that loudspeaker are automatically loaded.

Adjusting the Output Attenuation control of a single channel does not aect the level of other channels. The

only exception is if the ampliﬁer is attempting to deliver more than the total ampliﬁer wattage. If the total

ampliﬁer power is exceeded, the ampliﬁer will limit all outputs simultaneously and equally until the demand

is reduced. If the demand remains too high, the ampliﬁer will gradually limit to an average of 200 watts

continuously.

There are multiple ways to adjust output power in a PowerShare ampliﬁer application:

Adjust input signal level relative to the sensitivity setting of the ampliﬁer.

Adjust the Matrix level in ControlSpace Designer.

Adjust the Out levels in ControlSpace Designer.

Adjust the Output Attenuation controls of the ampliﬁer.

Adjust the CC-D ControlCenter digital zone controller(s) settings.

Adjust the limiter settings for each output using ControlSpace Designer software.

Adjust the transformer tap settings of any connected Hi-Z loudspeakers.
