7 Setting Up and Using Y our Har tke 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.

9 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.
10 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.
11 The specific EQ you will apply to your bass signal is very much dependent upon your par- ticular 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.
12 Rated Output Power (@ 1 kHz, 4 ohm, 1% THD) A70 70 w A100 100 w Rated Input Level (@ 1 kHz) Passive -20 dBu Active -10 dBu Total Harmonic Distortion (@ 1 dB below rated output, 1 kHz typical) A70 0.
