3 Crossovers (continued)
HAWKINS – This is a patented circuit developed by Soundstream many years ago. Hawkins has 2 controls but 3 functions. One of the controls is the boost and it is from
4Bass EQ – This circuit allows you to choose a frequency between 30Hz and 80Hz and boost that frequency by
5Xover Mode Switch – Select HP/FR for High Pass / Full Range and only the HIGH PASS functions will work. The High Pass filter is never off, but can be set to 15Hz which passes the entire audible spectrum to be reproduced. If you select LP/BP for Low Pass and Band Pass, then the LOW PASS function works as well. You can use the Low Pass in conjunction with the
Let’s say you have
6Input Gain – While most people set this control by ear to how loud they want their music, this is not the intent of this control. The range is from 0.2 volts to 9 volts. The control is meant for matching to the source unit’s output sig- nal voltage. For example, if you have a unit with low output voltage, you would probably have the control set fairly high, towards the 0.2V range. A lot of head units have 4 volts of signal voltage which mean that your con- trol would be set in midway through the range. If you happen to have a line driver (signal booster) that yields 9 volt or more, you will set the gain at the minimum position. In all of these examples, when properly level matched, the amplifier will put out full volume. Setting the control above the proper point may cause damage to the amplifier and speakers, and can result in poor sound quality and overall undesirable results…
7RCA Signal Inputs – Ummm… If you do not know what goes here, get over to your local Soundstream dealer immediately!
