Processor Use: Configuring the Processors (3-way Mono Stack)
Example 2- Active 3-way Mono Stack
In a 3-way configuration, the Top Box amplifier’s two channels are used for low- and high-frequencies and the
subwoofer handles bass. The Processors perform the required crossover and time delay functions.
This Top Box configuration has time delays included in the DSP chain to align the impulse response of the audio.
The upper signal chain is tuned for a 100 to 1200 hertz pass band and the EQ block compensates for any driver/
cabinet resonances. The lower signal chain is tuned for 1200 hertz and higher with back-to-back high-pass filters
and EQ for any required compensation.
The Subwoofer Processor would be configured similarly to the example on the previous page. Normally, the Top
and Sub processors receive the full range signal and extract their respective frequency ranges.
3-way Mono Stack Checklist: There are two ways to handle the signal routing for this application. In Discrete Mode, two input
cables are required, but if you have the option of controlling input signal levels of each, the overall subwoofer level can easily be
adjusted on the fly. In Combination Mode, only one input cable is required since the Top Box Processor’s CH1 Input is also connected to
the Subwoofer Processor (IN1 block). Any changes to input signal level will now effect both the MF/LF and subwoofer channels.
Changing subwoofer gain requires Signal Manager and a computer. Bass level should be managed with EQ.
