9.CD INPUT: Use this 1/8" stereo mini jack to connect the output from a CD play- er, MP3 player, laptop, etc., to the amplifier. The signal at this jack is summed into a mono signal, which is sent to the internal
power amp circuit. Use the output level control from the signal source to adjust the signal for the proper mix with your guitar.
Note: Depending on your CD player or other signal source device, you may need to use an adapter (i.e., two phono jacks to 1/8" stereo plug), available at most electronic outlets.
10.HEADPHONES: Use this 1/8" stereo jack to connect headphones to the amplifier. The internal speaker is disconnected when headphones are used.
Note: Depending on your headphones, you may need to use a stereo 1/8" plug to 1/4" jack headphone adapter, available at most electronic outlets.
CAUTION: To avoid possible damage to your hearing, do not use headphones for extend- ed periods of time at extremely loud levels.
11.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 head- phones in the Speaker jack! Permanent hearing damage could result!
12.POWER: Use this switch to turn the ampli- fier on (top of the switch depressed) and off (bottom of the switch depressed). The switch illuminates when the amplifier is turned on.
13.POWER CORD (rear panel, not
