Resumen del manual
This allows the master amplifier to control gain, filter, and sub-level on both amplifiers. This combination allows the amplifiers to drive their own separate subwoofer(s) while being synced together via an in- phase audio pre-amp signal from the master amplifier. Wiring connections to the amplifier subwoofer outputs in this combination should be standard in-phase configurations, creating a parallel speaker connection. (Refer to Parallel Synced Gain section of this guide for amplifier and speaker connection diagrams.) N NNO OOT TTE EE: ::One master amplifier can control up to three slave amplifiers in this combination. Multiple identical master/slave combinations can be added to any given system. External Synced Bridged In this master/slave combination the master amplifier pre-amp controls remain active and the slave amplifier pre-amp is bypassed. This allows the master amplifier to control gain, filter, and sub-level on both amplifiers. This combination allows the amplifiers to drive common subwoofer loads while being synced together via an out-of-phase audio pre-amp signal from the master amplifier. In this subwoofer wiring configuration the master amplifier sends the positive signal to the subwoofer while the slave amplifier sends the negative signal, making an externally bridged speaker connection. (Refer to External Synced Bridged section of this guide for amplifier and speaker connection diagrams.) N NNO OOT TTE EE: ::Amplifiers in this combination can only be connected in matched pairs. Multiple matched pairs may be added to drive separate subwoofer loads in a given system. Combined Amplifiers Gain and Filter Settings Set the Subsonic, EQ, and other filter settings on the master amplifier to the positions that achieve the best sound quality. Adjustment guidelines are discussed in the Crossover and Gain Adjustmentsection of this guide. © 2003 Directed Electronics, Inc PARALLEL SYNCED GAIN CONNECTIONS/SETTINGS 1.

Connect the speaker terminals of each amplifier to any combination of one or more subwoofers that results in nominal impedance between one and four ohms. Make sure that each amplifier sees the same speaker impedance. © 2003 Directed Electronics, Inc FIGURE 5—PARALLEL SYNC GAINED 750d/1500d Master 12 3 Slave 4 Do Not Use Do Not Use 2 Do Not Use Subwoofer Wiring (top view) 5 N NNO OOT TTE EE: ::The dual + and -- subout terminals of the 750d/1500d are paralleled internally and the combined load impedance should be taken into consideration when connecting multiple subwoofers. © 2003 Directed Electronics, Inc EXTERNAL SYNCED BRIDGED CONNECTIONS/SETTINGS 1.
