Setting Up and Using the
HS 1200 Bass Amplifier
2. The HS 1200 is shipped with a rear panel connector
between the speaker output (see #2 on page 6 of this
manual) and the built-in speaker input; check to make
sure this is in place; if not, plug it in. If you are using an
external speaker cabinet, make a connection between it
and the 1/4" unbalanced Speaker output connector on
the rear panel. Any appropriately rated external bass
cabinet with an impedance load of 8 ohms can be used,
though we recommend the use of the specially designed
internal speaker. It is never a good idea to power up
any amplifier that is not connected to a loudspeaker.
3. Next, connect the 3-pin AC plug into any grounded
AC socket. Don’t turn the HS 1200 on just yet, though.
4. Use a standard music instrument cable to connect
your bass to the Input jack on the front panel. On the
front panel of the HS 1200, turn the Volume control to its
minimum (fully counterclockwise) position, set all three
EQ controls to their “0” (12 o’clock) position, and start
with the Shape switch out (that is, off).
5. Press the front panel Power switch in order to turn on
the HS 1200; the LED above it will light up.
6. Set the output of your bass to maximum and then,
while playing, slowly turn the HS 1200 Volume control
up until the desired level is achieved. If you hear
distortion even at low amplifier Volume settings, back off
the output of your bass (or check for a faulty cable).
7. Press in the Shape switch and turn the Shape knob
both clockwise and counterclockwise to hear the effect
of the Shape curve and filter on the sound of your bass.
Leave the Shape knob at the point where it best comple-
ments your particular instrument and playing style.
