System Connections
Impulse 5t/8t use pins +1 / -1 for their input. Impulse 4t is wired +1 / -1 when used in full range passive
mode and +1 / -1 for the LF section and +2 / -2 for the HF section when used in 2 way active mode.
Impulse 3t is wired +1 / -1 for the LF section and +2 / -2 for the MHF section. Please make sure the rear
panel switch is set for the correct operating mode. The switch to change operating modes can be
found above the input speakons on the rear panel
All Impulse t series speakon connectors are wired in parallel, so either speakon can be used as the input.
The other speakon can be used as a link output. A positive signal to the + pin gives a forward cone
movement on all Impulse t enclosures.
Notes
Impulse 3t/4t feature a rotatable HF/MHF horn that allows the cabinet to be used in either vertical or
horizontal positions. To change the dispersion first loosen the screws that hold the grill in place.
Remove the grill and undo the screws holding the HF horn in place. Rotate the HF horn by 90 degrees
and replace the screws that hold it in place. Attach the grill and tighten the screws that hold it in place.
The HF/MHF horn on Impulse 3t and 4t are factory aligned for vertical cabinet positioning.
The Logos on Impulse 3t/4t are spring loaded and rotatable. This allows the logo to be displayed
upright when the cabinet is used in either vertical or horizontal positions. The handle cover plates can be
attached with the supplied screws if the handles are not required.
Precautions
Please consider the following precautions during use :
1. Install Impulse t series enclosures in a dry environment, do not expose the cabinets to rain or
moisture.
2. When flying or mounting Impulse 3t or 4t enclosures ensure safe working practices and follow the
recommended rigging guidelines.
3. Impulse series enclosures contain very powerful magnets. Do not locate an enclosure near any
sensitive equipment such as; VDU monitors, CRT TV's or high gain preamplifiers.
