1. LOUDSPEAKER CONNECTIONS The Impact 50 is provided with a recessed connector panel housing a pair of colour coded spring loaded push terminals These are used for input and loop out connections to further Impact 50 enclosures Note that looping out to additional enclosures has the effect of reducing the total load impedance on the amplifier For example two 16 ohm cabinets in parallel give a combined total impedance of 8 ohms It is possible to connect four Impact 50 cabinets in parallel to one amplifier channel providing that amplifier is capable of delivering long term power output into 4 ohms Never connect loudspeakers to a power amplifier whose total combined impedance is lower than the amplifier s recommended minimum load impedance Impact 50 manual page 5 user manual 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 CONNECTING CABLES Good quality loudspeaker cable should always be used throughout the installation with a minimum wire size of 12 gauge 1 5mm and preferably 10 gauge 2 5mm for longer runs keeping the run as short as possible This he2. plastic push rivets These are removed by placing a small flat blade screwdriver under the flange and carefully lifting upwards Set the grille aside for later re assembly Spare rivets are supplied in the accessory pack with your product for re fitting the loudspeaker grille Undo the four screws holding the driver in place and carefully lift it out and away from the cabinet Make a note of the driver polarity for later reconnection Disconnect the cables from the drive unit and completely remove the driver from the cabinet To reinstate the driver simply reverse the above procedure making sure you observe the correct polarity when reconnecting the cables back into the terminals of the drive units Removal of the high frequency tweeter 1 Remove the loudspeaker grille as described above and set the grille aside for later re fitting Undo the four screws holding the high frequency tweeter in place and carefully lift it out and away from the cabinet Make a note of the driver polarity for later reconnection Disconnect the cables from the drive unit and completely remove the driver from the cabinet To reinstate the high frequency tweeter simply reverse the above procedure making sure you observe the correct polarity when reconnecting the cables back into the terminals of the drive unit Impact 50 manual page 9 user manual Impact 50 Impact 50 manual page 10 APPENDIX A Spares and Accessories LS 50 TW 51 PX 5
