The electronic crossover is ideal for use with subwoofers and may also be used to crossover from low to mid, mid to high or low to high on biampable speakers. A signal can be sent to a completely separate amplifier if desired see page When connecting speaker cabinets, you must observe proper load impedances.
Whenever connecting multiple cabinets to an amplifier, the total load impedance must be calculated to insure proper performance from the amplifier. The table which follows shows the total load impedances of many common parallel speaker combinations:.
So, using two 16 ohm speakers in combination with one 8 ohm speaker, the imped-. You can also figure this on the table.
Note that some combinations result in impedances less than 2 ohms. They are included on the chart for reference only. The power output of an amplifier changes as the total load impedance increases or decreases. If each parallel connected speaker cabinet has the same rated impedance, divide the total power output by the number of cabinets used.
Speaker cabinets with different rated impedances will draw different amounts of power. To calculate the power output per cabinet, obtain the total load impedances from the impedance chart above and divide it by each speaker impedance.
For example: Three speaker cabinets, one with a rated impedance of 8 ohms and two at 16 ohms are connected in parallel.
According to the impedance chart, the total load impedance is 4 ohms, which means a total power output of watts as above. Divide the total impedance by the impedance of each speaker and multiply the results by These inputs accept Medium or Low impedance balanced or unbalanced signals. On each channel, both input jacks are wired in parallel; when one jack is used as an input, the remaining jack may be used to obtain a line out signal.
Each channel operates independently and has its own input connectors, sensitivity level controls, signal indicator LEDS, automatic limiter, fault protection circuitry, power amp, and speaker outputs.
One application of the Stereo Mode is using one channel of the amplifier for the left house speakers and the other for the right. The mixing board channels can be panned left or right according to the position of the instruments on the stage.
