Main Features
In Pursuit of High Sound Quality
The DS-30A powered monitor uses a two-way, bi-amplifier
design to achieve high sound quality.
The monitor features a 120-mm LF Driver and a 25-mm
soft-dome HF Driver as speakers. The amplification
includes 20-watt and 10-watt amplifiers designed to
achieve high sound 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 DS-30A is provided with digital input connectors (coaxial and optical) that support 96
kHz sample rate and 24-bit digital audio.
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.

this manual provides specific instructions directing you to do so). Refer all
servicing to your retailer, the nearest
Roland Service Center, or an authorized Roland distributor, as listed on
the “Information” page.
......................................................................
004
• Never use or store the unit in places
that are:
• Subject to temperature extremes
(e.g., direct sunlight in an enclosed
vehicle, near a heating duct, on top
of heat-generating equipment); or
are
• Damp (e.g., baths, washrooms, on
wet floors); or are
• Humid; or are
• Exposed to rain; or are
• Dusty; or are
• Subject to high levels of vibration.
......................................................................
007
• Make sure you always have the unit
placed so it is level and sure to remain
stable. Never place it on stands that
could wobble, or on inclined surfaces.
......................................................................
008a
• The unit should be connected to a
power supply only of the type
described in the operating instructions, or as marked on the unit.
......................................................................
008e
• Use only the attached power-supply
cord.
......................................................................
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!

• 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.
.....................................................................
014
• Protect the unit from strong impact.
(Do not drop it!)
.....................................................................
015
• Do not force the unit’s power-supply
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.
