Roland BR-800 用户手册

 

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.

• 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.

• 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.
