This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequen­cy energy and, if not installed and used in accordance with the instructions, may cause harmful interfer­ence to radio communications. However, there is no guarantee that interference will not occur in a par­ticular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications to this device not expressly approved by SLM Electronics could void the user’s authority to operate the equipment under FCC rules.

Congratulations!
You are now the proud owner of the Crate VTX350H three-channel guitar amplifier with Advanced Digital Signal Processing. This rugged amplifier combines outstanding features with serious clean and distorted sounds. Dual DSP controls provide 15 mod­ulation effects and 15 delay effects which can be combined for a wide variety of sounds. The Tap/Save button allows you to manually set the tempo of many of the effects and to save new DSP presets in the amplifier’s non-volatile memory. A separate Reverb control adds even more to the array of effects.
A highly visible electronic tuner (with a Mute switch for silent tuning) allows you to get tuned and stay in tune any time the amplifier is on. The rear panel Line In and Line Out jacks allow you to connect additional equipment for even greater flexibility.
Channel switching, Tap/Save, and a second bank of DSP effects may be controlled by means of the supplied four button footswitch.
Like all Crate products, your VTX350H amplifier is designed by musicians, and built using only the best components. Extensive testing confirms that this amplifier is the absolute best it can be.
In order to get the most out of your new amplifier, we strongly suggest that you read the information contained in this guide before you begin playing.
And thank you for choosing Crate.

1. 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 power is on.
2. REVERB: Use this control to adjust the amount of digital reverb effect. In its fully counterclock­wise position the signal will be “dry” (without any reverb). As you rotate the control clockwise the amount of reverb increases.
3. TAP/SAVE (LED): This LED flashes in time with the tempo set by the Tap/Save button (#4), and serves as a status indicator for certain DSP activities (see page 8).
NOTE: For some of the DSP effects, the Save/Tap LED remains illuminated. The Save/Tap LED does not illuminate when the DSP knobs are set to the Bypass position.
4. TAP/SAVE: Use this pushbutton to set the tempo of many of the effects by tapping the button repeatedly in time with the desired tempo. The Tap/Save button is also used to save DSP presets and to restore the factory default DSP settings. Additional information about the Tap/Save button is on pages 7 and 8.
5. DELAY: Use this control to select one of the fifteen digital delay effects. Complete information about the DSP effects is on page 7.
6. EFFECTS: Use this control to select one of the fifteen digital modulation effects. Complete information about the DSP effects is on page 7.
7. (ELETRONIC 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.
8. MUTE: This switch, when depressed, mutes the output signals at the Speaker jacks (#30) and the Line out jack (#28), allowing you to silently tune or switch instruments. The adjacent yellow LED illuminates when the Mute function is active.
9. 3 (CH 3 SELECT): This switch, when depressed, selects Channel 3 as the active channel. The adjacent red LED illuminates when Channel 3 is active. Channel 3 features a high gain FlexWave circuit for extreme distortion and sustain.

14. LOW: Use this control to adjust the low frequency level of Channel 3.
15. 2 (CH 2 SELECT): This switch, when depressed, selects Channel 2 as the active channel.
The adjacent yellow LED illuminates when Channel 2 is active. Channel 2 features a medium gain FlexWave circuit for moderate distortion and “crunch.”
16. HIGH: Use this control to adjust the high frequency level of Channel 2.
17. LEVEL: Use this control to adjust the output level of Channel 2.
18. MID: Use this control to adjust the midrange frequency level of Channel 2.

The adjacent green LED illuminates when Channel 1 is active. Channel 1 features a low gain FlexWave circuit for clean sounds or sounds with mild distortion.
22. HIGH: Use this control to adjust the high frequency level of Channel 1.
23. LEVEL: Use this control to adjust the output level of Channel 1.
24. MID: Use this control to adjust the midrange frequency level of Channel 1.
