Quick Start

Setting up your Hartke HD Series Combo Bass Amplifier is a simple procedure which
takes only a few minutes:
1.
Remove all packing materials and decide where the amplifier is to be physically
placed.
2.
Before you plug-in the power cable, be sure the Power switch is in the off posi-
tion. Connect the supplied power cable to the AC inlet located on the rear panel.
Then, plug-in the 3-pin AC plug into any grounded AC socket.
3.
Use a standard ¼" instrument cable to connect your bass to the Input jack on the
front panel.
4.
On the top panel of the amplifier, turn the Volume the minimum (fully coun-
terclockwise) position, set all EQ knobs to their twelve o'clock position and the
7-band graphic EQ sliders to the center position.
5.
Press the rear panel Power switch in order to turn on the amplifier.
6.
Set the output of your bass to maximum and then, while playing, slowly turn the
Volume control up until the desired level is achieved.
7.
Adjust the equalization controls to taste.
8.
Test the headphone output by turning the Volume control to its minimum (fully
counterclockwise) position and then connect a pair of headphones to the top-pan-
el 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.
9.
The HD Series amplifier features an AUX INPUT that you can use with a portable
CD or MP3 player to play with prerecorded tracks. You can plug any line level
signal into the AUX INPUT including the signal from a keyboard or drum machine.
Connect the line level device to the AUX INPUT using standard 1/8" cable. You
will need to use the volume control on the input device to set the balance between
the track and your bass. So, start with the volume control all the way down and
slowly raise it until you reach a good balance with your bass.
