6.0 TROUBLESHOOTING

Congratulations and thank you for purchasing the HUGHES & KETTNER BassBase 600!

The BassBase 600 represents our goal of designing the ultimate bass amp, featuring the cutting edge of
contemporary amplification technology. In respect to performance, sound quality, flexibility and workmanship,
we made our dream of the perfect bass amp a reality (and hopefully yours too).

In addition to all the tried-and-true features of classic bass amps, the BassBase 600 offers many innovative
details that will help you translate your ideas about sound into music.

In spite of its wealth of features, the BassBase 600 is designed to be straightforward to understand and easy
to operate. This manual will help you exploit the many options your new amp offers.

We wish you much enjoyment and success with your BassBase 600!

BEFORE OPERATING....

Check the voltage rating displayed next to the amp's AC socket. Make sure it matches your local AC current
before you plug the amp’s power cord into an AC outlet.

Place the amp on a sturdy, secure base (no, a stack of empty beer crates won't do). If you install the amp in a
rack, make sure the amp is supported from the rear, or is mounted at the bottom rack space.

HUGHES & KETTNER is not liable for damage to the amp due to incorrect installation in racks.

For safety purposes, the BassBase 600's power amp is exclusively equipped with Speakon jacks and female
XLR jacks. (In some cases, you may need to employ an adapter cable.)

NOTE: Under no circumstances should you use 1/4" plugs for connecting speaker cabinets to the BassBase
600; they are not designed to handle the amount of power this amp puts out.

3.0 SELECTING EQ SETTINGS/MIDI

You can activate the BassBase 600's two VARIMETRIC EQs and the FX LOOP in any one of three different
ways: via the front panel controls, the STAGEBOARD, or MIDI (once the MSM 1 MIDI Module has been
installed).

From the front panel, press the EQ ON button to enhance the basic EQ section (BASS and TREBLE), which
is always on, with the VARIMETRIC EQ. Now you can use the EQ A/B button to switch back and forth
between VARIMETRIC A and VARIMETRIC B.

From the Stageboard, use the same procedure to select a setting. The LEDs illuminate to indicate the current
switching status.
