INTRODUCTION

OWNER’S MANUAL MODEL 102/102 s sTEREO AMPLIFIER

• One pair XLR input connectors for

balanced system congurations.

Same gain and input impedance

characteristics are ensured whether

XLR or RCA adapted inputs are used.

• CE approved speaker output terminals

require no tools for secure, low resis-

tance connections.

mains operating voltage and ensures

consistent performance under all

operating and AC line conditions.

• Fully-balanced inputs provide

universal compatibility with other

components and eliminate ground

loop noise and EMI.

• High efciency ICEpower® power

conversion technology generates

high output power with very little heat,

promotes long component life and

permits a relatively small physical size.

• Low power consumption permits

constant power-up operation to

eliminate warm-up time.

• Ultra-low resonance, structurally

rigid chassis,

precision-machined

from a solid block of aircraft grade

6061-T6 aluminum.

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 Model 102 Stereo 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.

INITIAL INSPECTION

OWNER’S MANUAL MODEL 102/102 S STEREO AMPLIFIER

PO BOX 7231, COLORADO SPRINGS, COLORADO 80933 USA E-mAIL: jRDG@jEffROwLAND.COm www.jEffROwLAND.COm TELEPHONE (719) 473-1181

All JRDG products are designed to provide

a lifetime of enjoyment

and listening pleasure. The Model 102 Stereo

Ampliﬁer is uniquely

constructed from a solid block of precision-machined 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

lifetime of the product. All internal circuitry is maintenance-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 appearance.

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

OWNER’S MANUAL MODEL 102/102 S STEREO AMPLIFIER

Protection SyStemS

The Model 102 Stereo 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

ampliﬁer

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.

If you have any questions about the care or cleaning of your Model

102 Stereo 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.

PO BOX 7231, COLORADO SPRINGS, COLORADO 80933 USA E-mAIL: jRDG@jEffROwLAND.COm www.jEffROwLAND.COm TELEPHONE (719) 473-1181

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 Model 102 Stereo Ampliﬁer is energy efﬁcient, eliminating the need for

heatsinks or forced-air cooling. As a result, the Model 102 Stereo Ampliﬁer can be housed in

a cabinet or custom enclosure with no fear of overheating.

The efﬁcient and compact design of the Model 102 allows it to be

installed in any number of

music, ﬁlm and surround sound systems. For connection instructions for use in a typical two-

channel stereo system, please see page 11 of this manual.

The main chassis of the Model 102 is machined out of a solid block of aluminum to create

as rigid an enclosure as possible, impervious

to lateral and torsional forces. The ampliﬁer is

particularly non-resonant; however, various damping and resonance control accessories may

be used to yield greater audio performance in some audio systems.

RISK OF ELECTRICAL SHOCK!

WARNING

: Do not attempt to access the interior of the MODEL 102 STEREO AMPLIFIER by removing the bottom

cover. Doing so will void your warranty and could expose you to dangerous, potentially lethal electrical voltages.

InstallatIon, Use & care

OWNER’S MANUAL MODEL 102/102 S STEREO AMPLIFIER

The JRDG Model 102 Stereo

Ampliﬁer has been designed to

operate at the highest level of

efﬁciency and performance in

any normal operating situation;

however, there are a few impor-

tant use and care principles

that must be kept in mind when

operating the ampliﬁer.

• Do not expose the amplier to

rain, moisture, or excessively

damp conditions.

• Due to auto-ranging circuitry and

dual-stage voltage regulation, the

audio performance will not be

affected by any voltage uctuations

within the operating voltage range.

The Model 102 Stereo Amplier can

be operated at any mains voltage

over the range of 85 to 265 VAC

without any adjustments necessary.

•

The Model 102 Stereo 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 power switch

is turned off or AC power cable

is removed

before connecting or

disconnecting any loudspeaker or

interconnect cables.

• When operating the Model 102,

properly grounded AC receptacle

should be used. A potential shock

hazard may result if the supplied

3-wire, grounded AC cable ground

terminal is defeated or lifted or

the unit is connected to a 2-wire

ungrounded AC outlet.

• The Model 102 is designed to per-

form

optimally with no adjustments

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

Model 102 can be hazardous.

• Because of the energy efciency

of the Model 102, there is no need

to turn the unit off when not in use

except in the event of severe voltage

hazards as mentioned previously.
