vehicle, or otherwise subject it to temperature extremes.
Excessive heat can deform or discolor the unit.
355
• To avoid possible breakdown, do not use the unit in a wet
area, such as an area exposed to rain or other moisture.
Maintenance
401a
• For everyday cleaning wipe the unit with a soft, dry cloth
or one that has been slightly dampened with water. To
remove stubborn dirt, use a cloth impregnated with a
mild, non-abrasive detergent. Afterwards, be sure to wipe
the unit thoroughly with a soft, dry cloth.
402
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
558a
• To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels. You may prefer to use
headphones, so you do not need to be concerned about
those around you (especially when it is late at night).
559a
• When you need to transport the unit, package it in the box
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.
562
• Use a cable from Roland to make the connection. If using
some other make of connection cable, please note the
following precautions.
• Some connection cables contain resistors. Do not use
cables that incorporate resistors for connecting to this
unit. The use of such cables can cause the sound level
to be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable.
Copyright
851
• Unauthorized recording, distribution, sale, lending, public
performance, broadcasting, or the like, in whole or in part,
of a work (musical composition, video, broadcast, public
performance, or the like) whose copyright is held by a
third party is prohibited by law.
852a
• When exchanging audio signals through a digital
connection with an external instrument, this unit can
perform recording without being subject to the restrictions
of the Serial Copy Management System (SCMS). This is
because the unit is intended solely for musical production,
and is designed not to be subject to restrictions as long as
it is used to record works (such as your own compositions) that do not infringe on the copyrights of others.
(SCMS is a feature that prohibits second-generation and
later copying through a digital connection. It is built into
MD recorders and other consumer digital-audio
equipment as a copyright-protection feature.)
853
• Do not use this unit for purposes that could infringe on a
copyright held by a third party. We assume no responsibility whatsoever with regard to any infringements of
third-party copyrights arising through your use of this
unit.
Additional Precautions

buttons, sliders, or other controls; and when using its jacks
and connectors. Rough handling can lead to malfunctions.
556
• When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
internal elements.
557
•A small amount of heat will radiate from the unit during
normal operation.

5 7 8
When connecting the XLR input jack to a device that requires phantom power, turn this
on. When phantom power is being supplied, the PHANTOM indicator will light.
Supplying phantom power to a dynamic mic or an audio playback device
will cause malfunctions. Carefully read the owner’s manual of the device you
are using, and leave this turned off except when connecting a device that
requires phantom power (such as a condenser mic).
When phantom power is turned on/off, high-volume noise may be output,
which can damage your amp or speaker system. Be sure to turn down the
volume of audio equipment before you turn the phantom power on/off.
Turn phantom power off if nothing is connected to the XLR input jacks. Also,
to minimize noise, we recommend that you make the PAD indicator light and
turn the INPUT knobs that adjust the input sensitivity all the way to the
“+4dBu” position.
2 PAD Buttons 1–8
Switch the input sensitivity (adjustment range of the INPUT knob) for INPUT1–8.
When the PAD indicator is lit: +4 dBu– -44 dBu
When the PAD indicator is dark: -16 dBu– -64 dBu
3 PEAK Indicators 1–8
This will light when the input level of INPUT1–8 is excessive.
The PEAK indicator will light at the level at which the waveform clips (distorts). The
ideal level is when the sensitivity is raised as far as possible without causing the PEAK
indicator to light. If you wish to make more precise adjustments, watch the level meter
of the device connected via the R-BUS connector as you make adjustments.
4INPUT Sensitivity Knobs 1–8
Adjust the input sensitivity for INPUTs 1–8.
If you rotate the knobs, or push the PAD buttons while the MANUAL indicator is
lighted, the value currently indicated by the knob will be put in effect. Previous values
will remain in effect for knobs left untouched.

Front and Rear Panels
5MANUAL Button
6 CLOCK SOURCE Button
Selects whether operation of the front panel PHANTOM buttons / PAD buttons /
INPUT sensitivity knobs will be enabled or disabled. If you want to enable operation of
these buttons/knobs, make the MANUAL indicator light.
If you wish to remotely control the ADA-7000 from a device connected via
the R-BUS connector, make the MANUAL indicator go dark.
Selects the source of the sampling clock.
Turn down the volume on all devices connected to the R-BUS (RMDB2)
connector, RCA output jacks, and XLR output connectors (on the rear panel)
before operating this button.
R-BUS (RMDB2):
The ADA-7000 will operate according to the sampling clock of the device (e.g., digital
mixer or digital recorder) connected to the rear panel R-BUS connector. When a clock
signal is input from the R-BUS connector, the R-BUS indicator will light, and the
SAMPLING FREQ indicator for that sampling frequency will light. If no clock is being
input from the R-BUS connector, the R-BUS indicator will blink. If you have selected “RBUS (RMDB2)” as the sampling clock of the ADA-7000, you must set the master clock of
the connected device to be other than the R-BUS to which that ADA-7000 is
connected.
WORD CLOCK:
The ADA-7000 will operate according to the word clock signal that is connected to the
rear panel WORD CLOCK connector. When a clock is being input from the WORD
CLOCK connector, the WORD CLOCK indicator will light, and the SAMPLING FREQ
indicator for that frequency will light. If no clock is being input from the WORD CLOCK
connector, the WORD CLOCK indicator will blink. If you have selected “WORD
CLOCK” as the sampling clock of the ADA-7000, you must set the master clock of the
connected device to be the R-BUS to which that ADA-7000 is connected.
INTERNAL:
Select this when you want the ADA-7000 to operate on its own internal clock. Use the
SAMPLING FREQ button to set the sampling frequency. If you have selected
“INTERNAL” as the sampling clock of the ADA-7000, you must set the master clock of
the connected device to be the R-BUS to which that ADA-7000 is connected.
7 SAMPLING FREQ Button
If CLOCK SOURCE is set to “INTERNAL,” this selects the sampling frequency at which
the ADA-7000 will operate.
The ADA-7000 allows you to select a sampling frequency of 96 kHz. This is in
order to support 96 kHz compatible equipment that will become available in
the future. At present (December 1999), no devices with a 96 kHz compatible
R-BUS connector are available. For details, please contact your nearest
Roland Service Center, authorized Roland distributor, or your dealer.
