MAIN IN
This is a female XLR-type connector that accepts a balanced line-level signal from your mixing console or signal processor.
CONNECTIONS
The FUSSION 3000 has a female XLR input that accepts a balanced or unbalanced line-level signal. When connecting a balanced signal, be sure it�s wired per AES (Audio Engineering Society) standards: XLR Hot (+) Pin 2 Cold (�) Pin 3 Shield (Ground) Pin 1 There are also three male XLR connectors labeled LOOP OUT, SUB OUT, and FILL OUT. These are also wired according to the above AES standard.
LOOP OUT
This is a male XLR-type connector that produces exactly the same signal that is connected to the MAIN IN jack. Use it to daisy-chain several FUSSION 3000s together off the same signal source.
HIGH PASS/FULL RANGE
With the switch set to FULL RANGE position, the FUSSION 3000 operates from 55Hz to 20kHz. With the switch set to HIGH PASS, a high-pass filter is placed in the signal path and the FUSSION 3000 operates from 85Hz to 20kHz. Use this setting when you have a FUSSION 1800AS connected to the SUB OUT connector. Note: The LOOP OUT is not affected by this switch. It is always full-range, and the FILL OUT is always 85Hz to 20kHz.
SUB OUT
This male XLR-type connector produces a line-level signal that you can connect to the FUSSION 1800AS powered subwoofer system. The FUSSION 3000 has a built-in controller that operates below 85 Hz.
Balanced XLR Connectors
FILL OUT
This is a male XLR-type connector that produces a line-level signal you can connect to a side or front fill powered speaker or speaker amplifier. Note: The FILL OUT has a low-pass filter that operates from 85Hz to 20kHz, regardless of the FULL RANGE/HIGH PASS switch setting.
The LOOP OUT connector allows you to connect more than one FUSSION 3000 to the output of your mixing console. Simply plug the signal source output into the first MAIN IN jack, and patch that speaker�s LOOP OUT jack to the next MAIN IN jack, and so on, daisy-chaining multiple speakers. There is a limit to how many you can daisy-chain together. A general rule is to maintain a load impedance 10 times or more than the source impedance to prevent excessive loading on the source. For example, if your mixer has an output impedance of 120 ohms, then you can daisy chain up to sixteen FUSSION 3000s. This is a load of 1250 ohms (FUSSION 3000 input impedance=20k ohms; 16 of these in parallel=1250 ohms). The LOOP OUT jack is wired straight from the MAIN IN connector � there is no electronic circuitry between � so the signal coming out of the LOOP OUT jack is exactly the same as the signal going in.
OUTPUT LEVEL
This controls the output signal level at the FILL OUT. This control ranges from off up to unity gain. Use it to adjust the relative volume for the side or front fill speaker.
PHASE
This switch reverses the phase of the signal at the FILL OUT connector. Depending on the placement of the fill speaker, you may get better overall response with the PHASE switch set to 180º.
