• Do not connect plugs to both the XLR type and
phone type INPUT jack of the same number.
• You cannot use the GUITAR jack and the INPUT 8 jack
(phone type/XLR type) simultaneously. If devices are
connected to both jacks, the GUITAR jack input will take
priority. If you want to use the input from the INPUT 8
jack (phone type/XLR type), do not connect anything to
the GUITAR jack.
• If using the phone type INPUT jack, you must switch
phantom power off. For details, refer to "Using phantom
power" (p. 16).
• In order to handle audio with the SI-24 and to transfer
audio between the SI-24 and your computer, you must
connect it to a computer in which an R-BUS interface card
(RPC-1) has been installed.
• You must use a special R-BUS cable to make this connection.
The SI-24 cannot use a five meter R-BUS cable (RBC-5).
•
The R-BUS connector of SI-24 can not be used by connecting with
the equipment requires power supply via R-BUS such as DIF-AT,
VE-7000 and so on.
Be careful of loop connections

OUTPUT INPUT
When the SI-24 is connected as shown in the above diagram to a device that passes the input sound through
to its output (a DAT recorder/the Roland VS series that is recording), the SI-24 and that device will form a
loop that can cause oscillation, producing an unexpectedly loud sound.
This type of connection can cause malfunction and damage to speakers and other equipment; take care to
avoid these conditions.
In addition to the above figure, take a moment now to check your connections for the following conditions.
• Could there be a looped connection between the analog and digital realms?
• Has any looped connection resulted from insertion of a mixer or other piece of equipment between the
devices?
• To prevent malfunction and/or damage to speakers or

by:
1. Changing the orientation of the
microphone(s).
2. Relocating microphone(s) at a greater
distance from speakers.
3. Lowering volume levels.
