NOTE
Be sure to use only the AC adaptor supplied with the unit
(PSB-7U). Also, make sure the line voltage at the installa-
tion matches the input voltage specified on the AC
adapter's body. Other AC adapters may use a different
polarity, or be designed for a different voltage, so their use
could result in damage, malfunction, or electric shock.
NOTE
If you won't be using the BK-5 OR for an extended period
of time, disconnect the power cord from the electrical out-
let.

Backing Keyboard BK-5 OR
Before you start using the BK-5 OR
Connecting the BK-5 OR to an
amplifier, mixer, etc.
The BK-5 OR contains speakers and therefore doesn't
need to be connected to an external amplifier.
You can, however, connect the BK-5 OR's OUTPUT sock-
ets to an external amplifier (Roland KC-series) or the
audio inputs of an external instrument (digital piano,
etc.).
NOTE
To prevent malfunction and equipment failure, always turn
down the volume and turn off all units before making any
connections.
Turn the [VOLUME] knob all the way to the
left to minimize the volume.
Switch off all devices.
Connect the BK-5 OR's OUTPUT jacks to the
inputs of your external device.
Connecting the BK-5 OR to an amplifier
OUTPUT R +
L/MONO
For the connection to an amplifier, please choose
unbalanced (mono) cables with 1/4" plugs at one end
(for the BK-5 OR). The connectors at the other end
need to match the input sockets of the device to
which you are connecting the BK-5 OR.
NOTE
When connection cables with resistors are used, the vol-
ume level of equipment connected to the audio inputs may
be low. If this happens, use connection cables that do not
contain resistors.
