USB COMPUTER port
Use a USB cable to connect the BK-5 OR to your
computer via this connector (page 18).

AUDIO INPUT (STEREO) mini jack
This mini jack allows you to connect the audio out-
puts of an external signal source (CD/mp3 player,
synthesizer, etc.).
C
AUDIO OUTPUT R & L/MONO sockets
These sockets transmit all audio signals the BK-5 OR
generates as well as the signals you input to the
BK-5 OR.
NOTE
If you can/want to use only one channel on your external
amplifier, connect the L/MONO socket to its input. For opti-
mum sound quality, we recommend working in stereo,
though.
D
VIDEO OUTPUT socket
Connect this socket to the appropriate input of your
TV or external display.
NOTE
The signal format (PAL or NTSC) and aspect ratio are select-
able (page 71).
E
PEDAL HOLD socket
An optional Roland DP-series or BOSS FS-5U foot-
switch connected to this socket can be used to hold
the notes of the real-time parts. (The MELODY INTELL
part can also be sustained in this way.) This function
is also referred to as “sustain” or “damper”.
F
PEDAL SWITCH/EXPRESSION socket
Connect a separately available pedal switch (Roland
DP-series), a separately available foot switch (BOSS
FS-5U) or a separately available expression pedal
(Roland EV-5) to this jack (page 19).

(page 18).

With the factory settings, the BK-5 OR’s power will
automatically be switched off 30 minutes after you
stop playing or operating the BK-5 OR.
If the BK-5 OR’s power has been turned off automat-
ically, you can use the [POWER] switch to turn the
BK-5 OR back on. If you don’t want the power to turn
off automatically, set the “Auto Off” parameter to
“OFF” (page 72).
