Inspect the shipping container for damage. If any portion of the shipping container, packing material,
amplifier, or accessories are damaged or missing, notify your dealer and the shipper (if a claim is to
be made) immediately.
NOTE: Many shippers require notication and inspection within 24 hours of delivery to determine the nature of damages incurred.
Your CONTINUUM Integrated Amplifier has undergone extensive performance evaluations, listening
tests, quality control inspections, and a minimum 72 hour burn-in period prior to shipment and
should
therefore be in perfect operating condition upon delivery. If the amplifier does not operate
correctly, please notify your dealer immediately.
We strongly suggest that you save all of the packing materials. If the amplifier is returned to your
dealer or JRDG, the original packing materials must be used for shipment to avoid possible damage.
Neither JRDG nor the shipper can be held responsible for damages incurred during transit if the
original factory packing is not used. All factory returns require that JRDG issue a Return Authorization
(RA) number prior to shipment.

All JRDG products are designed to provide a lifetime of enjoy-
ment and listening pleasure. The
CONTINUUM Integrated Ampli-
fier is uniquely constructed from a solid block of precision-
m a c h i n e d
aluminum.
It’s chassis is sealed to prevent dust from entering the
interior of the chassis and thus should never need interior cleaning
during the life
time of the product. All internal circuitry is mainte-
nance-free such that no adjustments of any kind are necessary over
the lifetime of the product. If the amplifier is ever in need of service,
updating, or upgrading, it should only be returned to an authorized
repair facility or technician for servicing.
The front panel of the unit is precision-machined in a unique process
that incorporates a diamond tipped cutting tool. This process was
refined over many years to produce an attractive and unique appear-
ance. Because
the surface is not finished in the typical fashion of
most audio and
video equipment, there are a few rules that must be
kept in mind when cleaning the equipment.
• Please allow the front panel, which is coated with an automotive-grade polyure-
thane nish, to cure for 6 months before attempting to clean it.
This will prevent
small scratches from marring the surface before the surface coating has had a
chance to harden completely.
• The front panel of the unit should never be cleaned with anything other than a very
soft cotton cloth and plain water or ne oil-based furniture polish. Because of the
ne nish of the front panel, use of any other cleaning agent may permanently
scratch the nish.
• The top cover, sides and bottom are protected by a durable black anodized nish
and can be cleaned with a soft cotton cloth (such as an optical lens cleaning cloth
or ne furniture polishing rag) dampened with plain water. Water should be applied
directly to the cloth and not the chassis. A very mild plastic or glass cleaner that
does not contain ammonia may also be used. If a mark has been left on the
chassis,
do not use any type of abrasive or chemical cleaner to remove the mark.
Maintenance & cleaning

7
If you have any questions about the care or cleaning of your
CONTINUUM Integrated Amplifier, please contact your dealer or
the JRDG
factory before attempting to clean the chassis. The use
of a cleanser or abrasive to clean the chassis that has not been
approved by the factory will almost certainly damage the finish
and will not be covered under warranty.
NOTE: Cleaner/polish should be applied directly to the cloth and not the chassis.
Protection SyStemS
The CONTINUUM Integrated Amplifier is equipped with internal fuses
for protection against excessive AC current draw; however, since no
protection circuitry or system can completely protect a product from
every electrical hazard, certain precautions should be observed. In the
event of severe voltage hazards such as lightning or when the amp
lifier
will not be used for extended periods of time, the amplifier
should be
unplugged from the AC mains to avoid potential damage to the internal
circuitry. All other audio/video system components should also be
disconnected from AC mains power as hazardous voltages can easily
travel throughout an interconnected system.

Locate the amplifier as close as possible to its final installation point. Allow access to the rear panel
for making connections. Due to it’s design, the
CONTINUUM Integrated Amplifier is energy efficient,
eliminating the need for large heatsinks or forced-air cooling. However, the Continuum 500 should be
placed to allow ventilation around all sides to prevent overheating.
The efficient and compact design of the CONTINUUM allows it to be installed in any number of music,
film and surround sound systems. For connection instructions for a typical two-channel stereo system,
please see page 14 and 15 of this manual. For instructions regarding the use of the BYPASS INPUTS
for surround sound or home theater system use, please see page 15 of this manual.
The main components of the CONTINUUM are precision-machined from solid blocks of aluminum
to create as rigid an enclosure as possible, impervious to lateral and torsional forces. The amplifier
chassis is particularly non-resonant; however, various damping and resonance control accessories
may be used to yield greater audio performance in some audio systems.

The JRDG CONTINUUM
Integrated Amplifier has been
designed to operate at the
highest level of efficiency and
performance in any normal
operating situation; however,
there are a few important use
and care principles that must
be kept in mind when operating
the amplifier:
• Do not expose the amplifer
to rain, moisture, or excessively
damp conditions.
• Due to auto-ranging circuitry and
dual-stage voltage regulation, the
audio performance of the
CONTINUUM 500 will not be
affected by any voltage uctuations
within the operating voltage range.
The CONTINUUM 500 Integrated
Amplier can be operated at any
mains voltage over the range of 85
to 265 VAC without any adjustments
necessary. The CONTINUUM 250
Integrated Amplier requires internal
voltage change.
• The CONTINUUM Integrated Amplier
must not be modied in any way,
other
than according to ofcial service
bulletins from JRDG. Otherwise, the
factory warranty will be immediately
voided.
• Be sure the amplier is muted
(red front panel indicator light on)
before
connecting or disconnecting
any
interconnect cables.
• When operating the CONTINUUM,
a
properly grounded AC receptacle
should be used. A potential shock
hazard may result if the supplied
3-wire, grounded AC cable ground leave power switch ON and plug/
terminal is defeated or lifted or unplug unit from wall.
the unit is connected to a 2-wire
ungrounded AC outlet.
• The CONTINUUM is designed to per-
form
optimally with no adjustments
or
maintenance for the lifetime of the
product. Do not attempt to open the
bottom cover of the amplier and
refer all service issues to qualied
personnel. The voltages inside the
CONTINUUM can be hazardous.
• Because of the energy efciency
of the CONTINUUM, there is no need
to unplug the unit when not in use;
however, the amplier can be muted
if desired. The rear panel AC mains
switch is not intended for daily use.
Switch failure may result. Simply

installed
in a home theater or surround sound system for optimal play-
back of
stereo music sources when the multi-channel system is not
in use.
Pressing this button will allow a multi-channel processor to
bypass the amplifer functions of the CONTINUUM, with the volume
controlled only by the external processor. The indicator light below the
BYPASS button will illuminate blue to show that the Bypass function
is active.
NOTE: Do not connect a source component to the BYPASS INPUTS if it does not have
its own volume control. The volume control of the CONTINUUM Integrated Amplier is
inactive when Bypass Mode is selected.
(4) PHASE: Pressing this button will invert the phase of both channels
of the selected input and illuminate the yellow indicator light below
the PHASE button. Pressing this button again will turn off the light and
return the phase to uninverted polarity.
(5) MUTE MODE: Pressing the MUTE button will mute the speaker and
line outputs of the CONTINUUM and illuminate the red indicator light
below the MUTE button. Pressing this button again will turn off the light
and restore the output of the amplifier to the previous volume setting.
To avoid spurious noises and possible damage to other system
components, the amplifier should be muted when connecting or
disconnecting any rear panel connections.
(6) VOLUME DISPLAY: This display shows the current volume of the
selected input numerically, from 00.0 to 99.5, in 0.5 dB increments.
If desired, the volume display can be configured to turn off 5 seconds
after receiving any command from the front panel or the Remote Trans-
mitter. Please contact your dealer about this function. The volume display
also contains the infrared (IR) receiver for receiving remote commands.
(7) VOLUME CONTROL: Rotation of the volume control knob clockwise
will increase the output level of the CONTINUUM. Rotation of the knob
coun
ter-clockwise will decrease the output level. The CONTINUUM
features a
dual-range volume control system: rotating the volume
knob slowly will cause the volume to increase or decrease in small,
precise steps. Rotating the knob abruptly will result in large, immediate
changes to the output level.
NOTE: When the volume control is set to 85.5, the amplier is set for unity (0 dB) gain
from any input to any line output.

(1) UNBALANCED INPUTS: If you are using unbalanced RCA interconnects from your source
components (CD player, tuner, etc.), they should be connected to unbalanced INPUTS 1 and
2. If you have had the optional phono section installed in the CONTINUUM , the interconnects
from
the turntable should be installed into INPUT 1. For more information about the phono
option, please contact your dealer.
NOTE: To reduce audible pops when switching between inputs, install RCA “shorting” plugs, available from your JRDG
dealer, into all unused RCA unbalanced inputs.
The CONTINUUM Integrated Amplifier
offers
unprecedented compatibility with
associated audio and A/V components.
When connecting or disconnecting inter-
connect cables, the amplifier should be
placed

3) BYPASS INPUTS: If the CONTINUUM is
installed in a home theater or sound system,
the Left Front and Right Front output connec-
tions from
the surround processor should be
installed in the BYPASS input connec
tions.
The CONTINUUM will only accept unbal-
anced RCA interconnects from the surround
processor.
NOTE: If an external surround sound processor is not
connected, install RCA “shorting” plugs to both bypass
inputs.
(4) UNBALANCED LINE OUTPUTS: The
CONTINUUM also has one pair of RCA
unbalanced line level outputs. Use these
outputs if your amplifier does not accept
balanced inputs. Also, these outputs can be
used simultaneously with the balanced inputs
to feed a second amplifier (subwoofer, etc.)
(2) BALANCED INPUTS: If you are using
balanced XLR interconnects from your
source components, they should be
con
nected to balanced INPUTS 3 and 4.
A
slight mechanical click may be heard
when the balanced XLR interconnect cables
are correctly installed and locked into the
rear panel connector. The unlocking tab
must be pressed to disconnect the XLR
interconnect
cable from the amplifier. The
XLR inputs
may be left open if unused. Any
XLR input can be converted to an RCA input
by installing an XLR to RCA adapter, available
from your JRDG dealer.
NOTE: Pin 2 of each XLR connector is signal posi tive
with respect to each RCA input. Also, JRDG recom-
mends balanced cables as the
preferred method of
interconnection.
(5) BALANCED LINE OUTPUTS: The
CONTINUUM has one pair of balanced amplifier
line
level outputs. For best results, use these
outputs to connect to your power amplifier
whenever possible. If two sets of single-ended
outputs
are required then the balanced line
outputs can
be converted to single-ended
RCA outputs. JRDG recommends a single-
ended
adaptor box (Model PC-2XR) available
from Jensen
Transformers,
www.jensen-transformers.com.
NOTE: Pin 2 of each XLR connector is signal positive with
respect to each input and each unbalanced output.
(6) GROUND LUG THUMBSCREW: This
connection is reserved for units with the
optional phono section installed. When
connecting a turntable, the ground or earth
lead should be connected to the Ground
Lug Thumbscrew to eliminate any ground
noise in the system.
NOTE: Do NOT install RCA “shorting” plugs in the
unbalanced line outputs.

(A) LOUDSPEAKER OUTPUTS: Unscrew the knob that secures the speaker output connec-
tors on both the LEFT SPEAKER OUTPUT and the RIGHT SPEAKER OUTPUT and pull the
securing block out far enough to allow access to the binding posts. Install the positive (usually
red) loudspeaker cable spade terminal to the positive (+) binding post and the negative spade
terminal to the negative (-) binding post on both the LEFT and RIGHT CHANNEL. Secure the
loudspeaker connections by tightening the knob securely with your fingers. The CONTINUUM
will only accept spade terminated loudspeaker cables. Banana plugs or bare wire connections
can be used but require an optional clamp available from your JRDG Dealer.
WARNING: Both positive and negative outputs are
electrically active with respect to chassis
and/or
system ground potential. Therefore, this amplier cannot
be used in certain loudspeaker switching congurations,
such as those used in retail demonstrations. Failure to
avoid these precautions may short the outputs to ground
and can result in damage to the amplier and will void the
warranty. Certain subwoofer speakers which derive signals
from amplier outputs will require additional circuitry to
properly isolate the amplier output. Please contact JRDG
before connecting these types of subwoofers.

Install the AC Power Cable into the AC input connector (C) between the
amplifier and your AC mains outlet.
WARNING: If the unit is plugged into a voltage different from the range listed on the back
panel, it will result in serious damage and will void the warranty.
(C) POWER CONDITIONING: AC power conditioners and custom AC
mains power cables are
a common accessory in many high performance
audio and video systems and can be used to improve the quality of music
reproduction in certain instances. We have supplied the best
possible
basic power cord with the CONTINUUM; however, many users may wish
to use aftermarket AC power
cords available from many cable manufac-
turers
. Since we have not found an optimal universal power conditioner or
cable we cannot recommend any particular type or brand for use with the
CONTINUUM. Please use your dealer’s help and knowledge as a resource
to select the proper accessories for your individual system needs.
NOTE: Due to the exceptionally low power consumption rating of the CONTINUUM Integrated
Amplier, it is recommended that it not be disconnected from AC mains unless it is to be moved
or reinstalled in another location. It is recommended that the unit simply be left on when not in use.
WARNING: Serious damage to internal circuitry can occur if improperly wired or
unapproved AC power cords are used. Your dealer can be a helpful resource for
selecting the proper accessories based on your needs.
FIGURE 1: Detail of 12V remote trigger and mini-plug connector
requirements
NOTE: Please be aware that the remote feature simply places the
amplier in standby mode and does not disconnect the unit from
power or AC mains.
NOTE: If a 12V DC switching source is not available, then a short
circuit between the “tip” and “sleeve” of the 1/8” mini-plug connector
will place the amplier into the STANDBY MODE. Removing the
short circuit will return the amplier to the OPERATIONAL MODE.
