Before using this unit, carefully read the sections entitled: “IMPORTANT SAFETY
INSTRUCTIONS” (p. 2), “USING THE UNIT SAFELY” (p. 3, 4), and “IMPORTANT
NOTES” (p. 5). These sections provide important information concerning the proper
operation of the unit. Additionally, in order to feel assured that you have gained a

Main Features
●
In Pursuit of High Sound Quality
The DS-8/7/5 powered monitor uses a two-way, bi-
amplifier design to achieve high sound quality.
The LF driver and dome HF driver use separate amps
sections for LF and HF, ensuring optimal sound quality.
In particular, the DS-8/7 feature completely discrete DC
power amps for the highest possible quality.
●
Analog Input
In addition to an XLR connector, which provides for
balanced input, a 1/4" TRS phone jack accommodating either balanced or unbalanced input
is also provided. This assures broad-ranging connectivity.
●
Digital Input
The digital inputs (coaxial and optical) support 24-bit digital audio data at sampling rates up
to 192 kHz. AES/EBU professional audio format digital input is also provided.
Digitally input signals are reproduced faithfully through 24-bit D/A conversion, thus
preventing noise or a drop in sound quality.
You can use the monitors with a wide variety of equipment and applications through
selective use of the analog and digital settings.
●
Magnetically Shielded Low- and High-Frequency Drivers
This allows you to use the speakers next to CRT displays.

The ● symbol alerts the user to things that must be
carried out. The specific thing that must be done is
indicated by the design contained within the circle. In
the case of the symbol at left, it means that the powercord plug must be unplugged from the outlet.
008a
• The unit should be connected to
a power supply only of the type
described in the operating
instructions, or as marked on the rear side
of unit.
......................................................................
008e
• Use only the attached powersupply cord. Also, the supplied
power cord must not be used
with any other device.
......................................................................
009
• Do not excessively twist or bend
the power cord, nor place heavy
objects on it. Doing so can
damage the cord, producing
severed elements and short
circuits. Damaged cords are fire and
shock hazards!
......................................................................
010
• This unit, either alone or in
combination with an amplifier
and headphones or speakers,
may be capable of producing
sound levels that could cause
permanent hearing loss. Do not
operate for a long period of time
at a high volume level, or at a
level that is uncomfortable. If
you experience any hearing loss
or ringing in the ears, you should
immediately stop using the unit, and
consult an audiologist.
......................................................................
011
• Do not allow any objects (e.g.,
flammable material, coins, pins);
or liquids of any kind (water, soft
drinks, etc.) to penetrate the unit.
......................................................................
013
• In households with small
children, an adult should
provide supervision until the
child is capable of following all
the rules essential for the safe operation
of the unit.
......................................................................
012a
• Immediately turn the power off,
remove the power cord from the
outlet, and request servicing by
your retailer, the nearest Roland
Service Center, or an authorized
Roland distributor, as listed on the “Information” page when:
• The power-supply cord, or the plug
has been damaged; or
• If smoke or unusual odor occurs
• Objects have fallen into, or liquid has
been spilled onto the unit; or
• The unit has been exposed to rain (or
otherwise has become wet); or
• The unit does not appear to operate
normally or exhibits a marked change
in performance.
.......................................................................
014
• Protect the unit from strong
impact.
(Do not drop it!)
.......................................................................
015
• Do not force the unit’s powersupply cord to share an outlet
with an unreasonable number of
other devices. Be especially
careful when using extension
cords—the total power used by
all devices you have connected to
the extension cord’s outlet must
never exceed the power rating
(watts/amperes) for the
extension cord. Excessive loads can cause
the insulation on the cord to heat up and
eventually melt through.
.......................................................................
016
• Before using the unit in a foreign
country, consult with your
retailer, the nearest Roland
Service Center, or an authorized
Roland distributor, as listed on the “Information” page.

unplug the power plug and clean
it by using a dry cloth to wipe all
dust and other accumulations
away from its prongs. Also,
disconnect the power plug from
the power outlet whenever the
unit is to remain unused for an
extended period of time. Any
accumulation of dust between the power
plug and the power outlet can result in
poor insulation and lead to fire.
.......................................................................
104
