nected to AUX jack, you can play along on
your bass with a tape, etc. However the vol-
ume must be adjusted on the connected de-
vice.
*4 Connecting cables are sold separately.

dard mono cable to connect it to a bass amp
etc., only the L (left) output will be heard.
*6 PX4Bs output level and sound quality will vary
depending on which headphones are used.
We recommend using good quality low imped-
ance headphones, 32 Ohms or less with a
sensitivity rating near 100dB/mW or above.
Many headphones sold for use with portable
CD or cassette players will work just fine.

If the recording mode is set to "JAM," the maxi-
mum number of recordable measures will be au-
tomatically calculated from the tempo. Also, the
audio quality will be automatically set according to
the tempo and the specified number of measures.
If you select a long recording time (16 or 32),
the audio quality of the recording will be lower.
If the tempo of the rhythm is extremely slow, it
will not be possible to record a large number of
measures. Please re-specify the tempo in
Rhythm mode (maximum length is approximate-
ly 31.7 seconds)
Start playback on your CD or other audio source,
and at the point where you wish to begin record-
ing, press the ENTER/REC button. Recording
will begin.
If the recording mode is "JAM," recording will
begin after one measure of playback.
