THE FRONT PANEL:
1. LOW Z: Connect a low impedance microphone
here by means of a shielded signal cable
terminated with an XLR type connector.
2. HIGH Z: Connect a high impedance microphone
here by means of a shielded signal cable
terminated with a 1/4” connector.
3. LEVEL: Use this control to adjust the level of
the mic channel.
4. LOW: Use this control to adjust the low frequency
level for the mic channel.
5. MID: Use this control to adjust the mid frequency
level for the mic channel.
6. HIGH: Use this control to adjust the high frequency
level for the mic channel.
7. DSP SEND: Use this control to adjust the
amount of signal sent to the internal Digital
Signal Processor (DSP) for the mic channel.
8. INSERT: Use this jack to connect an external
effects device to the amplifier. This is a stereo
1/4” jack, wired as follows:
Tip = Line In (Return - from effect out)
Ring = Line Out (Send - to effect in)
Sleeve = ground
More information on the Insert jack can be
found on page 8.
9. INSTRUMENT INPUT: Connect an instrument,
tape player, CD player, or high impedance
microphone here by means of a shielded
signal cable terminated with a 1/4” connector.
10: GAIN (Active only with the Channel Select
switch depressed): Use this control to adjust
the gain for the instrument channel 1 – the
lower the setting, the lower the amount of distortion.
As this control is rotated clockwise, the
distortion increases and the output signal
becomes louder.
11: SHAPE (Active only with the Channel Select
switch depressed): Use this control to adjust
the tone of the instrument channel 1. Rotating
this control counter clockwise enhances mid
frequencies; rotating it clockwise enhances the
low and high frequencies.
12: LEVEL (Active only with the Channel Select
switch depressed): Use this control to adjust
the output level of the instrument channel 1.
13. CHANNEL SELECT: Use this switch to
select channel 1 or 2 for the instrument input.
With this switch depressed, the Gain, Shape,
and Level controls (#10 – 12) are active. With this
switch in the out position, the Low, Mid, High,
and Level controls (#14 – 17) are active. Channel
1 is typically used for electric guitars since the
Gain control can be cranked to produce heavily
overdriven distortion.
14. LOW (Active only with the Channel Select
switch out): Use this control to adjust the low
frequency level for the instrument channel 2.
15. MID (Active only with the Channel Select
switch out): Use this control to adjust the mid
frequency level for the instrument channel 2.
16. HIGH (Active only with the Channel Select
switch depressed): Use this control to adjust
the high frequency level for the instrument
channel 2.
17. LEVEL (Active only with the Channel Select
switch out): Use this control to adjust the output
level of the instrument channel 2.
18. DSP SEND: Use this control to adjust the
amount of signal sent to the internal Digital
Signal Processor (DSP) for the instrument
channel.
19. DSP MODE: Use this control to select the
type of Digital Signal Processing (DSP) effect
applied to the signal. The nomenclature around
the control is as follows:
BYPASS: No effect applied
SLAP: Moderate slapback delay
DELAY: Moderate delay with regeneration
ECHO: Long delay with regeneration
CHORUS: Moderate chorus effect
ROTARY: Simulated rotating speaker effect
CHO/HALL: Chorus combined with large reverb
ROOM: Small reverb effect
HALL: Large reverb effect
20. CD INPUT: Use these jacks to connect the
outputs of a CD player or tape player to the
amplifier. The output of the CD or tape player
may need to be attenuated for a suitable mix
with the input channels – see the notes on page
10.
21. FOOTSWITCH: Use this jack to connect a
footswitch to the amplifier for remote control of
the Instrument channel selection and turning
the DSP on and off. The jack is wired as follows:
Tip = Instrument channel selection
Ring = DSP control
Sleeve = ground
22. HEADPHONES: Use this jack to connect a
pair of stereo headphones for private practice
sessions. The internal speakers are disconnected
when headphones are used.
23. LED: This LED illuminates yellow when the
power switch is at the on position – when the
amp is fully charged. The LED illuminates red
when the battery needs recharging.
24. POWER: Use this switch to turn the amplifier
on (top of the switch depressed) and off (bottom
of switch depressed).

The TX50D is covered with a durable Tolex® material. To keep the cabinet in top
condition, wipe it clean with a damp, lint-free cloth to remove dirt and road film.
Never spray cleaning agents directly onto the cabinet, and stay away from abrasive
cleansers which could damage the finish.
