Guided Tour - HA3000 Front Panel1. Inputs - Connect your bass guitar to one of these standard 1/4" unbalanced jacks.If your bass has passive electronics (that is, if it has no battery), connect it to Input 1, whichis designed to handle low-level signals. If your bass has active electronics (that is, if it hasa battery), connect it to Input 2, which employs a 10 dB pad and is designed to handlehotter bass pickup signals.2. Volume control - This is the overall volume control. For best signal-to-noise ratio, keepthe output of your bass at or near maximum and set the HA3000 Volume to the desiredlevel.3. Shape control - In conjunction with the Intensity control (see #4 below), this controlapplies a specialized 20 dB notch filter to the specified frequency area so that you cancustomize the effect of the Shape curve to best complement your particular bassinstrument. Moving the Shape control clockwise causes the notch filter to be applied tohigher frequencies, while moving it counterclockwise causes it to be applied to lowerfrequencies. At the fully clockwise position, the filter is applied to the 1 kHz frequencyarea; this will act to attenuate mid-range frequencies and give your bass a deep, low tone.At the fully counterclockwise position, the filter is applied to the 90 Hz frequency area; thiswill act to attenuate low frequencies and give your bass a biting, trebly sound. For moreinformation, see the “Using Equalization and Shape” section on page 11 in this manual.4. Intensity control - Determines the degree to which the Shape curve (set with theShape control; see #3 above) affects the signal; the higher the Intensity, the greater theeffect of the notch filter. When set to 0, the Shape curve has no effect.5. EQ controls - These four controls provides approximately 15 dB of cut or boost at eachof four frequency areas: 80 Hz (Low), 220 Hz (Low Mid), 770 Hz (High Mid), and 5 kHz(High). When the equivalent knob is at the 12 o’clock (“0”) position, there is no boost orattenuation (flat response). As it is turned clockwise from the “0” position, thecorresponding frequency area is boosted; as it is turned counterclockwise from the “0”position, the corresponding frequency area is attenuated. For more information, see the“Using Equalization and Shape” section on page 11 in this manual.6. Direct Out - This standard balanced XLR jack provides an instrument-level outputsignal which is pre-EQ, pre-Shape and pre-Volume. This is generally used to send “dry”signal from the HA3000 to a PA system or recording mixing console.7. Status LEDs - The bottom “Power” LED lights whenever the HA3000 is powered on(see #8 below). The top “Clip” LED lights whenever the output signal rises to anunacceptably high distortion level. The center “Protection” LED goes on for approximatelyfive seconds when the HA3000 is powered on and fades slowly when it is powered off.While it is lit, all connected speakers are muted via mechanical relay, thus preventing any“thump” from occurring.8. Power switch - Use this to power the HA3000 on or off.52 3 51INPUT 1 INPUT 220dBU 10dBUDIRECT OUTBALANCED<100Ω –20dBuHartke01234 5 678910 901001151452153204507708509001K1234 5 6789MIN MAX-12-9-6-3 0 +3+6+9+12-15 +15-12-9-6-3 0 +3+6+9+12-15 +15-12-9-6-3 0 +3+6+9+12-15 +15-12-9-6-3 0 +3+6+9+12-15 +15VOLUME SHAPE INTENSITY LOW MID LOW MID HIGH HIGHHA3000 CLIPPROTECTPOWER4 6 7 8ENGLISH
