Soundstream Technologies 502, 1002, 702 manual

The RUBICON amplifiers incorporate an on-board staggered elec- tronic crossover, with RCA outputs to drive an external amplifier. No external electronic crossover is necessary. The high and low pass portions of the crossover can be set independently of one another.

To engage the High Pass filter, set the left crossover switch on the top of the amplifier to “H.P.X-OVER”, and use the frequency adjust- ment knob marked “H.P. X-OVER”. To engage the Low Pass filter, set the left crossover switch to either “SUB SONIC” or “HAWKINS BASS CONTROL” (see pages 1 O-1 1 for more details), and set the right crossover switch “L.P. X-OVER” to the “IN” position.

In many car audio installations, there is a tendency for a “midbass boom.” Because of their interior dimensions, most cars will reso- nate or ring at these midbass frequencies. If we design the system so there is reduced output in this region, the final response is very smooth and natural sounding. The high pass cossover is indepen- dently variable from 70 to 160 Hz at 12 dB/Octave, and the low pass crossover is independently variable from 55 to 220 Hz at 24 dB/Oc- tave.

For initial crossover setup, try setting the low pass filter to approxi- mately 60 Hz, and the high pass filter to approximately 100 Hz. Change the crossover points to accommodate a good mixture of frequency response, power handling, and personal preference.
