Quick Start

Setting up your Hartke TX300 Amplifier is a simple procedure, which takes only a few minutes.
1. Remove all packing materials (save them in case your unit requires servicing in the future) and
decide where the amplifier is to be physically placed. To avoid potential overheating, be sure
that the rear panel fan is unobstructed and that there is proper ventilation around the entire
unit.
2. Begin by hooking up your bass cabinet(s) to the twist-and-lock or 1/4" speaker output
connectors on the rear panel. Any appropriately rated bass cabinets with a total minimum
impedance of 4Ω (that is, 4Ω or greater) can be used. In order to ensure correct phase
correlation when using the 1/4" outputs, the tip of the amplifier's speaker jack should
be connected to the "+" (hot) input of your loudspeaker, and the sleeve of the amplifier's
speaker jack should be connected to the "-" (ground) input of your loudspeaker. When using
the twist-and-lock outputs, the +1 output should be connected to the "+" (hot) input of
your loudspeaker, and the -1 output should be connected to the "-" (ground) input of your
loudspeaker.
3. Next, connect the 3-pin AC plug into any grounded AC socket. Don't turn the amplifier on just
yet.
4. Use a standard shielded instrument cable to connect your bass to the TX300 INPUT jack on
the front panel. On the front panel of the, set the MASTER control to the 12 o'clock position
and set the GAIN knob to the fully counterclockwise "0" position. Set the COMPRESSOR
knob counterclockwise until it is in the "0" position, and set the EQ knobs to the 12 o'clock
position.
5. Press the Power switch on the rear panel to turn on the amplifier.
6. Set the output of your bass to its maximum level. Then, while playing, slowly turn the TX300
GAIN knob control up until the desired level is reached. If you hear distortion, even at a low
master MASTER setting, lower the GAIN control or back off the output of your bass. If the
problem persists, check for a faulty cable.
7. When you have settled on a GAIN and MASTER volume, the next step is to adjust the tonal
characteristics of your sound. Set the Drive control and three band EQ controls to taste. When
you get an equalization setting that complements your instrument and playing style, it's a good
idea to write it down for future use.
8. Now try out the compression circuit. As you rotate the COMPRESSOR knob, the input signal
from your bass becomes more compressed. You'll hear peak signals (such as string slaps and
pulls) begin to sound increasingly "squashed" relative to the lower-level signals produced
by standard playing. The result will be a decreased dynamic range, but an overall leveling of
signal throughout the full range of your instrument.
9. If you're using an external signal processor, turn the amplifier off momentarily and connect
a standard audio cable from the PREAMP OUT jack to your effects processor input, and a
second standard audio cable between the POWER AMP IN jack and your effects processor
output. Then turn the amp back on and play your bass while adjusting the controls of
your outboard effects processor. 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.
