ABOUT THE POWER SUPPLY:  
The TX50D uses a sealed lead-acid 12-volt battery as its internal power  
source. Unlike ni-cad batteries, this battery has no “memory” – it can  
be fully recharged at any time, without damage to the battery.  
When fully charged, the LED next to the power switch will glow yellow  
with the switch at the on (“I”) position. The LED will change to red  
when the battery is low and needs recharging. When this happens, turn  
the amp off, connect the 15-volt charger to the charger jack and plug it  
in. The LED near the charger jack will glow red while the amp is charg-  
ing and goes out when the amp is fully charged. The battery fully  
recharges within 6 hours, providing up to 8 hours of use at low levels,  
about 4 hours of use at moderate levels, and about 2 hours of use at  
continuous full power (sine wave). The battery is rated for up to 1000  
charging cycles. The charger can also function as an AC power supply.  
The battery inside the TX50D must be fully charged before operating  
the amplifier for the first time. Even though the amplifier leaves our  
factory with a charged battery, time spent in shipping may cause the  
battery to lose some of its charge.  
WARNING! Never connect the supplied 15VDC charger  
to the amplifier’s 12VDC Cigarette Lighter Adapter jack!  
Damage to the amplifier may occur!  
NOTE: If the battery is drained too low, the Power LED will go out. This  
indicates an exhausted battery – one which may not take a charge. If  
this happens, turn the amp off, connect the 15-volt charger to the  
charger jack and plug it in. If the Charger LED (see #25, page 8) doesn’t  
illuminate, the battery might be beyond recharging. (The TX50D uses a  
“smart” charging circuit and will not allow you to charge a defective  
battery.) If the battery is serviceable, the LED will glow once the battery  
reaches 10 volts – leave the charger plugged in and let the battery fully  
recharge. If the LED never illuminates, the battery may need replacing.

ABOUT THE POWER SUPPLY (continued):  
The TX50D may also be powered by using a 12-volt vehicle cigarette  
lighter adapter, available at most electronic supply stores. Make certain  
that the polarity on the adapter matches what is shown below.  
POSITIVE  
NEGATIVE  
Connect the small round end of the adapter to the 12VDC Automobile  
adapter jack (#26, page 8), then plug the other end of the adapter into  
the vehicle’s cigarette lighter socket. (In some vehicles, the ignition  
switch must be in the “on” or “accessory” position to have power at the  
socket.) NEVER PLUG THE SUPPLIED 15VDC CHARGER INTO THE  
AMPLIFIER’S 12VDC LIGHTER PLUG!  
When using the DC cigarette lighter adapter, the vehicle’s battery will  
keep the amp charged to its voltage level – if the battery has a 13.5-volt  
charge, the amp will charge up to 13.5 volts; if the battery is low and  
only has a 10-volt charge, the amp will discharge down to 10 volts.  
CAUTION! The TX50D contains a sealed, rechargeable,  
lead-acid battery. Improper disposal of battery or replace-  
ment with any other type may cause leakage, explosion,  
and/or injury. See page 4 for additional information. Also,  
refer to product warranty information.

1. LOW Z: Connect a low impedance micro-  
phone here by means of a shielded signal cable  
terminated with an XLR type connector.  
9. INSTRUMENT INPUT: Connect an instru-  
ment, tape player, CD player, or high imped-  
ance microphone here by means of a shielded  
signal cable terminated with a 1/4connector.  
2. HIGH Z: Connect a high impedance micro-  
phone here by means of a shielded signal cable  
terminated with a 1/4connector.  
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 dis-  
tortion. As this control is rotated clockwise, the  
distortion increases and the output signal  
becomes louder.  
3. LEVEL: Use this control to adjust the level of  
the mic channel.  
4. LOW: Use this control to adjust the low fre-  
quency level for the mic channel.  
5. MID: Use this control to adjust the mid fre-  
quency level for the mic channel.  
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.  
6. HIGH: Use this control to adjust the high fre-  
quency 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.  
12: LEVEL (Active only with the Channel Select  
switch depressed): Use this control to adjust  
the output level of the instrument channel 1.  
8. INSERT: Use this jack to connect an external  
effects device to the amplifier. This is a stereo  
1/4jack, wired as follows:  
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.

22. HEADPHONES: Use this jack to connect a  
pair of stereo headphones for private practice  
sessions. The internal speakers are discon-  
nected when headphones are used.  
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:  
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.  
BYPASS: No effect applied  
SLAP: Moderate slapback delay  
DELAY: Moderate delay with regeneration  
ECHO: Long delay with regeneration  
CHORUS: Moderate chorus effect  
24. POWER: Use this switch to turn the amplifi-  
er on (top of the switch depressed) and off (bot-  
tom of switch depressed).  
ROTARY: Simulated rotating speaker effect

SUGGESTED SET-UPS:  
The TX50D can be used in a variety of different ways, some of which are  
shown below and on the following page. Use these ideas to fuel your  
imagination for the setup which best suits your needs.  
Idea 1 Play and sing, with external effects and backup: Connect a micro-  
phone to the Low Z jack. Connect an instrument (acoustic or electric gui-  
tar, keyboard) to the Instrument Input jack. (This high-Z input works with  
all types of pickups, from Piezo to active types.) Connect a rhythm  
machine to the CD Input jacks. A two-button footswitch may be used to  
select Instrument Channel 1 or 2 and to turn the DSP on and off. Connect  
the external effects device to the Insert jack using one of the methods  
shown on page 8. (Note that the external effect will be applied equally to  
both channels, as well as the CD inputs, so use with discretion.)

Idea 2 Play along: Connect an instrument (acoustic or electric guitar,

er to either the CD Input jacks or to the Low Z jack of the remaining  
channel. (See the notes on page 10 for more detailed infromation.) A pair  
of stereo headphones may be connected to the Headphones jack for pri-  
vacy.

SUGGESTED SET-UPS (continued):  
Idea 3 Sing along: Connect a low impedance microphone to the Low Z  
jack. Connect a high impedance microphone to the Instrument Input jack.  
Connect a tape player (for sound tracks and back up music) to the CD  
Input jacks. A single button footswitch may be used to turn the DSP on  
and off.

Notes:  
When a tape player or CD player is connected to the CD Input jacks,  
the output of the player may need to be adjusted by means of its out-  
put level control (if it has one), or by an external attenuator/preamp.  
A tape player or CD player may be connected to either channel instead  
of to the CD Input jacks. This provides control of the gain and equaliza-  
tion of the signal, as well as the application of DSP if desired. In this  
case, the left and right outputs of the tape or CD player must be  
summed to create a mono signal, such as shown below.

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 abra-  
sive cleansers which could damage the finish.  
Crate continually develops new products, as well as improves existing ones. For this reason,  
the specifications and information in this manual are subject to change without notice.
