1. PASSIVE Input jack - If your bass guitar has passive circuitry, connect it here. This
standard, 1/4" unbalanced jack provides a high impedance (>1MΩ) input sensitiv-
ity of 20 mV.
2. ACTIVE Input jack - If your bass guitar has active circuitry, connect it here. This stan-
dard, 1/4" unbalanced jack provides a high impedance (>1MΩ) input sensitivity of
60 mV. Note: Bass guitars that have active circuitry normally require a battery for
the circuitry to be functional.
3. MUTE Switch - When engaged, this orange backlit switch mutes all of the outputs.
4. COMPRESSOR Knob - This knob determines the amount of compression by adjusting
the threshold level. The compressor allows you to control the overall dynamic range
of your performance by reducing sudden peaks, and increasing the sustain of the
instrument. At the fully counterclockwise position, no compression is applied. As
the knob is turned clockwise an increasing amount of compression is applied. When
the compressor is engaged the lights around the COMPRESSOR knob flashes yellow
providing a visual indicator of the status of the compression circuitry.
5. GAIN Knob - This control adjusts the amount of level provided to the tube preamp
stage. The lights around the GAIN knob will flash red when clipping occurs in the
preamp signal path. If you notice that the light is continuously flashing red, turn
the GAIN control down until the indicator no longer lights.
6. BRITE switch - Use this switch to turn on the BRITE circuit, which when engaged,
adds a preset EQ curve to enhance the bass instrument's high-end response. When
engaged the switch will light orange.
7. BASS (80Hz) Knob - As part of the passive tone stack equalizer, this control is used
to adjust the low frequency response.
8. SHAPE Knob - The SHAPE control knob is used to set the depth of the mid-band EQ.
9. FREQUENCY Knob - This control knob is used to set the center frequency for the mid-
band EQ. The range is from 200Hz to 800Hz.
10. TREBLE (6k) Knob - As part of the passive tone stack equalizer, this control is used
to adjust the high frequency response.
11. MASTER Knob - This is the overall volume control for the amplifier.
12. AUX Input - Use this 1/8" (3.5mm) input to connect a line level device like a porta-
ble CD or MP3 player.
13. Headphones jack - Connect headphones to this standard 1/8" (3.5mm) jack. When
a plug is inserted into the headphone jack, the speaker output is disconnected,
allowing you to use your TX600 as a practice amplifier.
