Active - Connect your bass guitar to this standard 1/4" unbalanced jack.
Guided Tour - Front Panel 8. Limiter Control - This determines the amount of compression (peak signal reduction) by simultaneously adjusting both threshold and compression ratio (which ranges from 2:1 to infinity [limiting]). At the fully counterclockwise “Zero” position, the circuitry is bypassed and no compression is applied. As the knob is raised clockwise (at settings from “1” to “10”), increasing amounts of compression are applied. 9.
Guided Tour - Rear Panel A. AC Power Inlet - Use the supplied grounded AC power cord to connect your A Series amplifier to mains power. This cord comes supplied with the appropriate plug for your geographic area. CAUTION: Do not use an adapter to defeat the third grounding pin on this plug or severe electric shock may result! B. Speaker Output – The jack is used to connect the internal 8-ohm aluminum driver. C.
Setting Up and Using Your Hartke A SERIES Combo Bass Amplifier Setting up your Hartke Systems A Series Combo Bass Amplifier is a simple procedure which takes only a few minutes: 1. Remove all packing materials (save them in case of need for future service) and decide where the amplifier is to be physically placed. You may decide to use the “kickback” position for additional directionality and high frequency clarity.
Setting Up and Using Your Hartke A SERIES Combo Bass Amplifier 9. Test the headphone output by turning the Volume control to its minimum (fully counterclockwise) position and then connect a standard stereo headphone to the front panel Phones jack. While playing your bass, slowly turn the Volume control up—you should hear sound from the headphones and none from the connected speaker. We recommend the use of large size headphones (those with large transducers) for optimum bass reproduction. 10.
Using the CD Input Your A series amplifier features a CD input which you can use with a portable CD player, cassette, mini disk or MP3 player to jam with pre-recorded tracks or learn a riff from a favorite tune. In fact, you can plug any line level signal into the CD input including the signal from a keyboard or drum machine. Connect the CD player or other Line level device to the CD Input using standard RCA cable.
Using Equalization The Hartke Systems A Series Bass Amplifier gives you enormous control over shaping the sound of your bass, using a process called equalization. To understand how this works, it’s important to know that every naturally occurring sound consists of a broad range of pitches, or frequencies, combined together in a unique way. This blend is what gives every sound its distinctive tonal color.
Using Equalization The specific EQ you will apply to your bass signal is very much dependent upon your particular instrument and personal taste and playing style. However, here are a few general suggestions: • For that super-deep reggae or Motown sound, boost the Bass EQ slightly while attenuating the Treble EQ. •To remove boxiness and make your instrument sound more “hi-fi,” try attenuating the Mid EQ control. •For a twangy, cutting sound, try boosting the Treble EQ.
