1. mmm AISISISISIS ar Loudspeaker Connection Tri Mode Stereo Satellite Subwoofer iPaul 4 300 The amplifier is likewise suitable for loudspeaker connection in tri mode at the FRONT and REAR outputs and can be used for rear deck systems with subwoofers With the application of this wiring suggestion the connection of the loudspeaker system and the subwoofer should occur on the rear deck at the outputs REAR and connection of a front loudspeaker system at the outputs FRONT Fig 10 Attach the rear deck loudspeaker system at the terminals 7 as described in the section Loudspeaker Connection Stereo above Additionally an 8Q or 4Q subwoofer over a passive crossover on the clamps RL and RR will be attached The mechanical load of the woofer of the rear deck loudspeaker system will fall at low frequencies because of the limits on electrical load set by the cone excursion when no security measures for the lower frequency range have been made If the loudspeaker system is operated without additional high pass the total power handling of the system will be determined by the maximum power handling of the loudspeaker system Disadvantages of this circuitry are the decreased channel separation as well as the inability to regulate the subwoofer level The advantage is however in the compactness of the system which is ideal for elevated placement Figure 10 Loudspeaker Connection2. REAR 9 RR RL must be occupied by a Y RCA cable which will then distribute the signal to both RCA sockets during mono operation Recommendation The amplifier part FRONT is intended for use as broadband or high pass for the front system A mono bridge connection for the amplifier part Front is only recommended for broadband and or high pass operation mode when the amplifier for purpose of maximum performance is used separately for the left and right sides Use amplifier part REAR over the low pass at 80 Hz for a subwoofer in mono bridged connection Use amplifier part FRONT over the high pass at around 60 Hz for a kickbass front system Fig 9 The connection impedance of the loudspeakers during mono operation may not fall below 4Q in order that the critical minimum connection impedance of 202 is maintained A 2Q loudspeaker connection is not permitted for reasons of thermal power load limitations Note An 802 loudspeaker impedance on the mono bridge represents a material impedance of about 402 on the amplifier At 40 the material impedance is only around 202 and at 2Q it is only around 10 The halving of the impedance is achieved through the allocation performed by the mono clamps bridging the two internal amplifiers Figure 8 Loudspeaker Connection Mono Bridged KT BRIDGED T BRIDGED Figure 9 Loudspeaker Connection FRONT Stereo REAR Bridged Recommended sa BRIDGED BRIDGED
