7ENGLISH6Setting Up and Using Your HartkeB Series Combo Bass AmplifierSetting up your Hartke Systems B Series Combo Bass Amplifier is a simple procedure which takesonly a few minutes:1. Remove all packing materials (save them in case of need for future service) and decide wherethe amplifier is to be physically placed. To avoid potential overheating problems, make sure thatthe rear panel is unobstructed and that there is good ventilation around the entire unit.2. Connect the 3-pin AC plug into any grounded AC socket. Don’t turn the B Series on just yet,though.3. Use a standard music instrument cable to connect your bass toone of the Input jacks on the front panel. If your bass has passiveelectronics (that is, if it has no battery), connect it to Passive Inputwhich is designed to handle low-voltage signals. If your bass hasactive electronics (that is, if it has a battery), connect it to ActiveInput, which has a 10 dB pad and is designed to handle hotter basspickup signals.4. On the front panel of the B Series, turn the Volume control to itsminimum (fully counterclockwise) position, set all three EQ controlsto their “0” (12 o’clock) position, and, if you are using a B600 or B900 ,set the Shape control to its 12 o’clock position.5. Press the front panel Power switch in order to turn on yourB Series amp; the LED in the switch will light up.6. Set the output of your bass to maximum and then, while playing,slowly turn the B Series Volume control up until the desired level isachieved. It’s nearly impossible to overload the B Series amplifier, soif you hear distortion even at low Volume settings, check for a faultycable (if it’s good, simply back off the output of your bass).7. If you are using a B600 or B900 , turn the Shape knob both clock-wise and counterclockwise to hear the effect of the Shape curveand filter on the sound of your bass. Leave the Shape knob at thepoint where it best complements your particular instrument andplaying style.8. Adjust the three equalization controls to taste (when you get agreat setting that complements your instrument and playing style,it’s a good idea to write it down for future use).9. Test the headphone output by turning theVolume control to its minimum (fully counter-215B00_OM_5L_v5.indd 7 3/30/06 11:37:50 AM
