Making Connections
A slot (cord hook) for securing the AC adaptor cord is built
into the bottom of the BR-800.
To prevent the inadvertent disruption of power to your unit
(should the plug be pulled out accidentally), and to avoid
applying undue stress to the AC adaptor jack, anchor the
power cord using the cord hook, as shown in the
illustration.

Using the Cord Hook
• To prevent malfunction and/or damage to speakers
or other devices, always turn down the volume, and
turn off the power on all devices before making any
connections.
• Howling could be produced depending on the
location of microphones relative to speakers. This
can be remedied by:
1. Changing the orientation of the microphone(s).
2. Relocating microphone(s) at a greater distance
from speakers.
3. Lowering volume levels.
• This instrument is equipped with balanced (XLR/
TRS) type jacks. Wiring diagrams for these jacks are
shown below. Make connections after first checking
the wiring diagrams of other equipment you intend
to connect.
The XLR connector of INPUT 4 can provide 48 V
phantom power, allowing you to connect a
phantom-powered condenser microphone (p. 140).

• Some connection cables contain resistors. When
connection cables with resistors are used, the sound
level may be extremely low, or impossible to hear.
For information on cable specifications, contact the
manufacturer of the cable.
• When using the FS-5U foot switch (sold separately),
set the polarity switch as shown below.
fig.00-130.eps
• Use only the specified expression pedal (Roland
EV-5, BOSS FV-500L/FV-500H; sold separately).
By connecting any other expression pedals, you risk
causing malfunction and/or damage to the unit.
• When using an expression pedal, set the pedal’s
MIN volume to “0.”
Polarity Switch
• Do not use excessive force when pressing the cord
into the cord hook. Doing so may break the cord.
• When turning the unit upside-down, get a bunch
of newspapers or magazines, and place them
under the four corners or at both ends to prevent
damage to the buttons and controls. Also, you
should try to orient the unit so no buttons or
controls get damaged.
• When turning the unit upside-down, handle with
care to avoid dropping it, or allowing it to fall or
tip over.
