Operation
Connect guitar to input (1) via a 6.3mm jack lead
If mp3 or other playback is to be used, connect this to the 3.5mm MP3 IN connector (8)
If headphones are to be used for silent practice, connect these to the 6.3mm PHONES jack (9)
Turn the VOLUME control fully down and all other controls to the vertical (12 o’clock) position
Connect to mains using the supplied mains lead via the rear panel IEC connector and switch POWER on (11)
Gradually turn up the volume and play until sound is heard and increase to the required level
Adjust BASS, MIDDLE and TREBLE controls to achieve the required tone character
If “feedback” causes howling or squealing through the speaker, cutting certain EQ levels can help curtail this
It is advised to position the guitar facing away from the CA-15 and not too close in order to avoid feedback
To give a special effect, the internal chorus can be engaged by pressing in the CHORUS ON/OFF switch (5)
Depth of this effect can be adjusted with the CHORUS control (6)
Turn down the VOLUME control before unplugging the guitar or switching off the CA-15
Caution
Do not cover cooling vents at the rear of the amplifier. Keep away from damp or dusty environments
Check mains lead is in good condition and ensure mains outlet voltage is correct as indicated.
Use only approved fuse rated as shown. Unplug from mains before replacing fuse.
