Setup

Unpacking and Inspection

Carefully unpack your K3000FX amplifier. Inspect the unit for any signs of damage that may have occurred during transit. If damage is found, contact your dealer immediately. Retain the original packing materials for future shipping or storage.

Placement

Place the amplifier on a stable, level surface. Ensure adequate ventilation around the unit. Avoid placing it in direct sunlight or near heat sources. The K3000FX also features an integrated 35-mm pole socket for stand mounting, allowing it to be used as a PA system.

Power Connection: Connect the supplied power cord to the AC inlet on the rear panel and then to a suitable power outlet.
Channel Inputs (1-4): Each channel features 1/4" stereo inputs. Channel 1 also includes an additional XLR microphone input for direct connection of dynamic microphones.
CD Input: Use the RCA (phono) inputs to connect an external audio source like a CD player or MP3 player for playback or practicing along.
Headphone Output: Connect headphones to the dedicated 1/4" stereo headphone jack for quiet practicing.
DI Output: The balanced stereo XLR DI output with a Ground Lift switch allows for direct connection to a mixing console or external PA system.
Link Output: Connect this output to a slave amplifier (e.g., another K3000FX) for true stereo operation or to expand your sound system.
Subwoofer Output: Connect an active subwoofer to this output for enhanced low-end power.

Operating Instructions

Powering On/Off

Ensure all connections are secure before powering on. Turn the MASTER VOLUME control to its minimum setting. Press the POWER switch to turn on the unit. Wait a few seconds for the amplifier to stabilize before increasing the volume. To power off, reverse this procedure.

Channel Operation

The K3000FX features four independent stereo channels, each with dedicated controls:

Volume Control: Adjusts the input level for each channel.
FX Send Control: Determines the amount of signal sent from each channel to the internal digital effects processor.
Channel 1 XLR Input: For connecting dynamic microphones.

Digital Effects Processor

The integrated 24-bit digital FX processor offers 100 presets, including reverb, chorus, flanger, delay, pitch shifter, and various multi-effects. Use the FX program selector to choose your desired effect. The FX RETURN level in the Main section controls the overall wet/dry mix of the effects.

FBQ Feedback Detection System

The revolutionary FBQ Feedback Detection System instantly reveals critical frequencies that cause feedback. When feedback occurs, the corresponding LED on the 7-band graphic EQ will illuminate, indicating which frequency band needs adjustment to eliminate the feedback.

7-Band Graphic EQ

Use the dedicated 7-band graphic equalizer to shape your sound. Adjust the sliders for each frequency band to boost or cut specific frequencies, optimizing the amplifier's output for your instrument and acoustic environment. The FBQ system works in conjunction with this EQ.

Main Section Controls

FX Return Level: Controls the overall level of the effects returned to the main mix.
Master Volume: Adjusts the overall output volume of the amplifier.
Phones Level: Controls the volume of the headphone output.
Shape Switch: Engages a specific equalization curve for a quick tonal adjustment.

Maintenance

Cleaning

Clean the amplifier's exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or waxes, as these can damage the finish. Ensure no liquids enter the unit.

Storage

If storing the amplifier for an extended period, ensure it is in a dry, dust-free environment. It is recommended to use the original packaging for protection.

Troubleshooting

Problem	Possible Cause	Solution
No sound output.	Power cord not connected. Amplifier not powered on. Volume controls set too low. Input cables faulty or incorrectly connected. External device not sending signal.	Check power cord connection. Ensure power switch is ON. Increase Channel Volume and Master Volume. Verify all cables are securely connected and functional. Check the output of your connected instrument/device.
Distorted sound.	Input signal too high. Master Volume too high. Faulty cable or instrument.	Reduce input level on the instrument or channel volume. Lower the Master Volume. Test with different cables and instruments.
Feedback (howling sound).	Microphone too close to speaker. Specific frequencies are resonating.	Reposition microphone or speaker. Use the FBQ Feedback Detection System to identify and cut problematic frequencies on the 7-band EQ.
