Being a passive Equalizer, it contain power amplifiers to drive speakers directly, Also provides one stereo signal line output and 1 pair sub-woofer output can be connected to remote highpower amplifiers. The ten center-frequencies are connected in the critical 50Hz to 12Hz region where compensation is most needed. 6.

Most speaker systems require rather heavy boost at the lowest frequencies due to the large amount of air that must be moved. Speaker woofer cones responder between 45-60Hz where output is higher so do not boost much at 60Hz. Use heavy boost at 100Hz, less boost at 400Hz. 2. Due to sound-wave reflections between the front and rear windshields of a typical vehicle, there may be heavy loss between 700Hz to 1.3KHz so moderate boost here is very effective and will create more presence for vocalists. 3. The mid-range from 3 to 6KHz should not require much change from flat [center] most speakers work well here. Adjust per your taste. 4. Due to limitations in human hearings. Sound above 8KHz is not heard very well. Moderate boost at 1KHz adds a crisp character when percussion instruments are present. 1. FADER KNOB Allow front to rear balancing in four speaker systems for best directional imaging. 2. EQ SLIDE CONTROLS Each slide controls the amount of boost or cut in one small part of the total audio frequency range. With all slides in the center position, the overall frequency response is flat. By moving any slide up or down. The output within the band is increased or decreased by up to 12db. 3. LED INDICATOR 4. CD INPUT JACK 5. POWER BUTTON Press it to turn on or off the unit. ...
