Impact 50

TRANSFORMER TAP SETTINGS

The constant voltage Impact 50T is fitted with a 4–way input connector. Always connect the speaker cable corresponding to the negative terminal on the amplifier to the blue terminal. The cable corresponding to the positive terminal should be connected to one of the following terminals:

	70 volt line		100 volt line
RED	30W	200 ohms	60W	200 ohms
YELLOW	15W	400 ohms	30W	400 ohms
GREEN	7.5W	800 ohms	15W	800 ohms
BLUE	Common terminal		Common terminal

CONNECTING CABLES

Good quality loudspeaker cable should always be used throughout the installation, with a minimum wire size of 12 gauge (1.5mm2), and preferably 10 gauge (2.5mm2) for longer runs, keeping the run as short as possible. This helps to avoid wasting amplifier power in the resistance of the cable. High cable resistance also lowers the damping factor of the amplifier that affects its ability to control loudspeaker cone movement.

POSITIONING

The Impact 50 has been designed with a rear facing port, which reinforces the low frequency response of the speaker. Increased low frequency performance can be achieved by placing the Impact 50 near to a wall. Even greater benefit is achieved if the unit is placed in a corner. The optimum distance from the rear of the enclosure to the wall is between 30–100 mm. Using the WB-50 adjustable mounting bracket will ensure the loudspeaker is located at an ideal distance from the wall.

INSTALLING THE IMPACT 50

The enclosure may be installed using a variety of different methods:

♦Using the WB-50wall bracket supplied, which allows for horizontal and vertical adjustment. Disassemble the WB-50 bracket and attach the speaker plate to the Impact 50 using the M6 screws provided. Attach the wall plate at the desired position and then re–assemble the bracket, tightening the thumbwheel after positioning the speaker to give the desired coverage.
