Volume Adjust the volume of channel 1. 2. Bass Adjusts low-frequency gain of channel 1. 3. Treble Adjusts high-frequency gain of channel 1. 4. Reverb Adjust the intensity of the reverb effect. Channel 2: Passive Guitar Input 5. Guitar EFX Dedicated reverb switch for channel 2 (passive guitar). Press to activate reverb effect on Channel 2; release to disable. Note: Microphone channel reverb is always active. 6. Volume Adjust the volume of channel 2. Channel 3: B.T Wireless System 7. B.T Function Short Press: When B.T is disconnected, short press to activate pairing mode (LED flashes rapidly); when connected, short press to play/pause music. Pairing Process: Use B.T search to find device named "Crush20" and connect. After successful pairing, LED stays solid with confirmation tone. Long Press (2s): Disable B.T function. 8. Battery Indicator Four LEDs display battery level (each 25% capacity); when the red light turns off, the amplifier enters standby mode and ceases audio output. 9. Master Volume Adjust final output volume for all channels. 10. Channel 2 Input Jack Standard 1/4" (6.35mm) input interface. Connect passive guitars or dynamic microphones. 11. USB-C Charging Port Recharge using included cable with 5V/2A charger (charger not included). 12. Charging Status Light Illuminates solid red during charging, and turns off when fully charged or not being charged. 13. Channel 1 Input Jack Standard 1/4" (6.35mm) input interface. Connect dynamic microphones or active guitar. 14. Power Switch Toggle upward to power on, toggle downward to power off. Tips Active Guitar: Require battery-powered pickups with built-in preamps, delivering strong signals that need connect to Channel 1's low-impedance input to prevent distortion from overload. Passive Guitar: Use non-powered magnetic pickups generating weaker signals, requiring Channel 2's high-impedance input to avoid volume loss and noise interference.

To operate Crush20 safely, please read the entire manual. 1. Battery Charging Fully charge the battery via USB-C (5V/2A) before use. 2. Initial Tone & Effect Setup Set bass and treble to 12 o'clock position, reverb to 9 o'clock position, turn all volumes down for neutral baseline. 3. Connect Instrument Connect your instrument or microphones to channel 1/ channel 2 input with shielded 6.35mm cables. 4. Set Tone & Effect Turn on the power switch. While playing, adjust bass, treble and reverb, then calibrate channel volume by playing intensely and reducing volume when distortion occurs. 5. Volume Optimization Slowly raise master volume to desired level. Tips Always minimize master volume before power-on to prevent speaker damage from power surge and avoid hearing injury from unexpected loud sounds Troubleshooting 1. Can't Turn on the Machine A. Check the battery level to ensure that it is sufficiently charged. B. Check that the power switch is in upward position. 2. Unable to Charge A. Use only the included 5V/2A USB-C cable. B. Ensure power source is 5V/2A DC. C. If left unused for months, recharge every 3 months to maintain battery health. 3. B.T Cannot Connect A. Check whether B.T can be turned on normally. B. If the B.T indicator light does not flash but remains lit, it is possible that another device is connected, please disconnect from the other device and then retry pairing. 4. Audio Distortion/Low Volume A. If using a passive guitar, ensure it is connected to Channel 2 input. B. If using an active guitar or microphone, connect to Channel 1 input. C. Reduce the channel volume if distortion occurs during playback. 5. No Sound from Microphone A. Confirm the microphone is a dynamic type, condenser microphones are not supported. B. Ensure the microphone is properly connected to Channel 1. C. If the microphone requires a battery, check that it is…
