Setting Up and Using Your
HA3000 / HA4000
7. Set the output of your bass to maximum and then, while playing, slowly turn the Volume
control up until the desired level is achieved. It's nearly impossible to overload the HA3000
or HA4000 input, so if you hear distortion even at low Volume settings, check for a faulty
cable (if it's good, simply back off the output of your bass) or, if your bass has active
electronics, a low or dead battery.

instrument and playing style. For more information on the use of these controls, see page
11 in this manual.
9. Adjust the equalization controls to taste (when you get a great setting that complements
your instrument and playing style, it's a good idea to write it down for future use). For more
information on the use of these controls, see page 11 in this manual.
10. If you need to connect the HA3000 / HA4000 to a PA system or a recording mixing
console, turn it off temporarily and then connect a cable between either the Direct Out or
Preamp Out output and the mixer. (See #6 on page 3, #10 on page 8, #8 on page 4, or
#12 on page 8 for more information). If you hear any hum or buzz in the signal, try
changing the setting of the rear-panel Ground Lift switch.
11. If you need to connect the HA3000 / HA4000 to an external slave amplifier, turn it off
temporarily and then connect a cable between the Line Out output and a -20 dBu input on
the external amplifier. (See #7 on page 4, or #11 on page 8 for more information).

between one of the Return jacks and your effects processor output (if required, multiple
effects processors can be daisy-chained together, output to input). Use the Pre Send if
you want the signal to be sent pre-EQ and pre-Shape; use the Post Send if you want the
signal to be sent post-EQ and post-Shape. Use the Pre Return if you want the signal to be
returned pre-EQ and pre-Shape; use the Post Return if you want the signal to be returned
post-EQ and post-Shape. If required, both the Pre and Post sends and returns can be
used simultaneously, though in matched pairs only (severe feedback and speaker damage
can result if you use a Post Send and a Pre Return!). Once all Send and Return
connections are made, turn the HA3000 / HA4000 back on and play your bass while
adjusting the controls of your effects processor(s). For best results, set both the input and
output gain of all connected effects processor(s) to 0 dB (unity gain), so that there is no
increase or decrease in level whether the effects are switched in or out.
13. If you're using an HA4000 and want to use a Mute Footswitch and/or tuner, turn the
power off temporarily and then connect it to the appropriate rear-panel jack (see #3 on
page 7 and #8 on page 8 for more information). If you want to use the SBASS out to send
subharmonic signal to an external amplifier driving a subwoofer, turn the power off
temporarily before making the connection (see #9 on page 8 for more information).
If you encounter difficulty with any aspect of setting up or using your Hartke HA3000 or
HA4000, call Samson Technical Support (1-800-372-6766) between 9 AM and 5 PM EST.
8. Experiment by setting the Intensity control to its 12 o'clock
6 position and then turn the Shape knob both clockwise and
