INPUT jack
Devices such as an audio player can be connected to this jack via a
stereo mini-plug.
* To adjust the volume, use the controls of the connected
device (e.g., audio player).
31
OUTPUT L/MONO (TREBLE) jack
32
OUTPUT R/MONO (BASS) jack
These jacks can be connected to an amplifier, a mixing console or
a wireless system. If you use both connectors, the FR-4x’s output
is stereo. In that case the signals of the right-hand keyboard
section are transmitted to the L/MONO jack, while the R/MONO
jack transmits the bass (and chord) signal. If you only use one jack
(connected to the “L” or “R” jack), the FR-4x’s output is mono.
MEMO
5
On the FR-4x, connecting to these jacks does not mute the
internal speakers.
5
By holding down the [SHIFT] button and pressing the [5/12]
button you can turn the speakers on/off (p. 17). Switching off
the FR-4x’s speakers allows you to save battery power.
33
PHONES jack
This is where you can connect stereo headphones.
Connecting a pair of headphones mutes the internal speakers.
MEMO
You can change a setting so that the internal speakers produce
sound even when headphones are connected (p. 17).
Securing the Cable
Proceed as follows to ensure that a MIDI cable–or an audio cable–
doesn’t come loose while you are playing.
Your FR-4x comes with an attachment strip that allows you to
secure optional MIDI as well as audio cables to the right strap.
1.
Wind the attachment strip around the cable and the
strap.
