*2 If a CD player or other audio source is con-
nected to the AUX jack, you can play along
to it with your guitar. However the volume
must be adjusted from the connected device.
*3 Connecting cables are sold separately.
*4 The PX4A’s output jack is stereo. If you use
a standard mono cable to connect it to a gui-
tar amp etc., only the L (left) output will be
heard.
*5 The PX4A’s output level and sound quality
will vary depending on which headphones
are used. We recommend using good quali-
ty low impedance headphones, 32 Ohms or
less with a sensitivity rating near 100dB/mW
or above . Many headphones sold f or use with
portable CD or cassette players will work just
fine.
