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.

The BK-5 contains speakers and therefore doesn’t need
to be connected to an external amplifier.
You can, however, connect the BK-5’s OUTPUT sockets
to an external amplifier (Roland KC-series) or the audio

For the connection to an amplifier, please choose
unbalanced (mono) cables with 1/4” plugs at one end
(for the BK-5). The connectors at the other end need
to match the input sockets of the device to which
you are connecting the BK-5.

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.
