Product input voltage description Indicates that the rated operating voltage of the product is 110-120V Indicates that the rated operating voltage of the product is 220-240V 5 APPLICATIONS Stereo Operation D-1000.4 can be used in the stereo mode as two separate 2000 watt units; each capable of driving loads down to 4 ohms. Each channel operates independently and has its own input connectors, sensitivity level controls, automatic limiter, fault protection circuitry, power amp, and speaker outputs. The default settings of the mode is stereo mode. This approach provides a more accurate reproduction of the live performance. PROFESSIONAL AMPLIFIER Mono Bridge Operation The two internal power amplifiers (CHA and CHB or CHC and CHD) can be bridged together to form a single, higher powered amp. This is especially useful when using the amplifier to power a sub woofer. In the mono mode, the amplifier uses the channel A or C input jacks and sensitivity control(channel B and D's are disabled). When operation in this mode, each channel is independently protected. The minimum speaker load impedance must be 8 ohms. Please set the amplifier as follow: Link CHA and CHB ,or CHC and CHD, Set the phase of the CHB or CHD to 180 4 OHMS SPEAKERS SIG A SIG C SIG B SIG D 4 OHMS SPEAKERS 8 OHMS SUBWOOFER SIG 1 SIG 2 8 OHMS SUBWOOFER 4 OHMS SPEAKERS 4 OHMS SPEAKERS 6 7Corel PDF Engine Version 9.397
