Two-Channel Guitar Amplifier with DSP

Congratulations

and thank you for choosing the Crate VTX30 Guitar Amplifier with Digital Signal Processing. This rugged amplifier features a Clean channel with a three-band EQ and level control, and a Solo channel with our patented FlexWave technology, Gain, Level and Shape control. An easy to operate DSP section lets you dial in a variety of digital effects including reverbs, delays, octave and wah-wahs. RCA input jacks allow connection of a CD or tape player for practicing with your favorite music, while the Headphones jack allows you to practice in private. The top-mounted electronic tuner allows you to get tuned and stay in tune any time the amplifier is on.

In order to get the most out of your new amplifier, we strongly urge you to read this guide before you begin playing.

And thank you for choosing C TE .

IMPORTANT SAFETY INSTRUCTIONS

• READ, FOLLOW, HEED, AND KEEP ALL INSTRUCTIONS AND WARNINGS.

• DO NOT OPERATE NEAR ANY HEAT SOURCE AND DO NOT BLOCK ANY VENTILATION OPENINGS ON THIS APPARATUS. FOR

PROPER OPERATION, THIS UNIT REQUIRES 3” (75mm) OF WELL VENTILATED SPACE AROUND HEATSINKS AND OTHER AIR

FLOW PROVISIONS IN THE CABINET.

• DO NOT USE THIS APPARATUS NEAR SPLASHING, FALLING, SPRAYING, OR STANDING LIQUIDS.

• CLEAN ONLY WITH LINT-FREE DAMP CLOTH AND DO NOT USE CLEANING AGENTS.

• ONLY CONNECT POWER CORD TO A POLARIZED, SAFETY GROUNDED OUTLET WIRED TO CURRENT ELECTRICAL CODES AND

COMPATIBLE WITH VOLTAGE, POWER, AND FREQUENCY REQUIREMENTS STATED ON THE REAR PANEL OF THE APPARATUS.

• PROTECT THE POWER CORD FROM DAMAGE DUE TO BEING WALKED ON, PINCHED, OR STRAINED.

• UNPLUG THE APPARATUS DURING LIGHTNING STORMS OR WHEN UNUSED FOR LONG PERIODS OF TIME.

• ONLY USE ATTACHMENTS, ACCESSORIES, STANDS, OR BRACKETS SPECIFIED BY THE MANUFACTURER FOR

SAFE OPERATION AND TO AVOID INJURY.

• WARNING: TO REDUCE THE RISK OF ELECTRIC SHOCK OR FIRE, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE..

• SERVICE MUST BE PERFORMED BY QUALIFIED PERSONNEL.

• OUR AMPLIFIERS ARE CAPABLE OF PRODUCING HIGH SOUND PRESSURE LEVELS. CONTINUED EXPOSURE TO HIGH SOUND

PRESSURE LEVELS CAN CAUSE PERMANENT HEARING IMPAIRMENT OR LOSS. USER CAUTION IS ADVISED AND EAR PRO-

TECTION IS RECOMMENDED IF UNIT IS OPERATED AT HIGH VOLUME.

1: INPUT: Use this 1/4” jack to connect your guitar to the amplifier by means of a shielded instrument cable.

SOLO CHANNEL: A high gain channel giving you sounds from a slight edge to serious overdrive.

2: GAIN: Use this control to adjust the amount of distortion for the Solo channel.

3: SHAPE: Use this control to adjust the tone of the Solo channel.

4: LEVEL: Use this control to adjust the output level of the Solo channel.

5: SOLO/CLEAN: Use this switch to select the Solo or Clean channel. With the switch in the out position, the Clean channel is selected. When the switch is depressed, the Solo channel is selected.

CLEAN CHANNEL: A normal gain channel designed to give you crystal clear sounds to medium distortion.

6: LEVEL: Use this control to adjust the output level of the clean channel.

7: LOW: Use this control to adjust the low frequency level of the clean channel.

8: MID: Use this control to adjust the midrange frequency level of the clean channel.

9: HIGH: Use this control to adjust the high frequency level of the clean channel.

10: DSP LEVEL: Use this control to adjust the level of the selected digital effect. The DSP effects can be turned on and off by using a footswitch (#17, rear panel).

11: (DSP MODE): Use this control to select one of the 16 built-in digital effects. The nomenclature around the control is further explained in the chart on page 6.

12: CD INPUT: Use these RCA jacks to connect the output from a CD payer or tape deck to the amplifier. The signal at these jacks is summed into a mono signal which is sent to the internal power amp circuit. Use the CD or tape player’s output level control to adjust the signal for the proper mix with your guitar.

13: HEADPHONES: Use this jack to connect headphones to the amplifier. The internal speaker is disconnected when headphones are used.

CAUTION: To avoid possible damage to your hearing, do not use headphones for extended periods of time at extremely loud levels.

14: POWER: Use this switch to turn the amplifier on (top of the switch depressed) and off

(bottom of the switch depressed). The switch illuminates when the amplifier is turned on.

15: TUNER: The electronic tuner is active whenever the amplifier is turned on, providing constant, “real-time” tuning. The bottom row of LEDs indicate which note (string) is being tuned. The top row of LEDs provides directional queues to facilitate quick and precise tuning of your instrument. The indicated note

(string) is properly tuned when only the center

LED is illuminated.

The Bottom Panel (not shown):

16: EXTENSION SPEAKER: Use this jack to connect the amplifier to an external speaker. The internal speaker is disconnected when this jack is used. The impedance of the external speaker must be 4 ohms or greater.

WARNING: Do not attempt to use headphones in the Speaker jack! Permanent hearing damage could result!

17: FOOTSWITCH: Use this jack to connect the 1/4” stereo plug on the cable of a two-button footswitch (such as the Crate CFP2). This allows you to remotely switch between the

Clean and Solo channels and turn the DSP function on and off.

18: POWER CORD: The grounded power cord should only be plugged into a grounded power outlet that meets all applicable electrical codes and is compatible with the voltage, power, and frequency requirements stated on the bottom panel. Do not attempt to defeat the safety ground connection.
