MODEL M98ED T-2

CUSTOM MAGNETIC

CARTRIDGE

BlRADlAL (ELLIPTICAL) STYLUS

DATA SHEET

FREQUENCY RESPONSE:

From 20 to 20,000 Hz

OUTPUT VOLTAGE:

4 7 millivolts per channel at 1,000 Hz at 5 crnJsec peak recorded velocity

STYLUS: Model N95ED B~radial (Ellipt~cal)

Side Contact Radius:

5

microns (.0002 in.)

Frontal Radius: 18 microns (.0007 in.)

Grip Color: Yellow

TRACKABILITY:

This indicates h o w well a stylus can follow or track the signals i n a record groove without losing con- tact. To provide an unbroken f l o w o f signals from the record, the phonograph cartridge nlust be able to track the grooves. Signals recorded at a higher level (measured i n cm/sec peak recorded veloc- ity) are more difficult to track.

(Higher stylus forces within specified range im- prove trackability.)

TRACKING FORCE RANGE:

3/4 to 1-1/2 grams

This is the amount of force required of the stylus tip to properly play a record. The lighter the track- ing force within the recommended range, the longer the life of the stylus and records, provided that tracking is maintained.

CHANNEL SEPARATION (minimum):

25 dB at 1,000

Hz

INDUCTANCE:

650 millihenries

D.C. RESISTANCE

1550 ohms

OPTIMUM

LOAD:

47,000 ohms resistance i n parallel with 400 to 500 picofarads total capacitance per channel. Load re- sistance can be up t o 70,000 ohms w i t h almost n o audible change i n frequency response. Total ca- pacitance includes both tone arm wiring and amplifier input circuit.

MOUNTING:

12.7 mm (standard 1/2 in.) mounting centers

WEIGHT:

6.3 grams

TERMINALS:

4 terminals

OPERATION:

The M98ED T-2 DYNETIC@ phonograph cartridges have been developed for use with all high fidelity amplifiers h a v ~ n g magnetic and constant velocity inputs. Recommended track~ng force is 314 to

1 - 7 / 2 grams. Forces greater than 1-1/2 grams should not

be

used.

Mounting

The M98ED T-2 DYNETIC@ Cartridge has 12.7 mm

(standard 1 / 2 in.) mounting centers. Hardware is supplied w i t h each cartridge for mounting pur- poses I n some tone arms and plug-in shells, the cartridge sits so deep that the stylus cannot be conveniently replaced. For these applications, spac- ers are provided t o insure adequate clearance for stylus removal.

For optimum vertical tracking angle, the cartridge should be mounted so the top o f the mounting block is parallel to the record playing surface.

Connections

4-LEAD STEREO CONNECTION: Connect "hot" lead

(usually red) of right channel to terminal "R" and shield or ground lead of right channel (usually green) to terminal "RG". Connect "hot" lead of left channel (usually white) to terminal "L" and h e l d or ground lead of left channel (usually blue) to

"LC".

To prevent "ground loops" and hum, no common connection should be used at cartridge terminals.

MONOPHONIC OPERATION: For monophonic play- back, connect left and right channels i n parallel.

This is accomplished most conveniently by setting function switch on associated amplifier to " A t B " o r "MONO".

CAUTION:

D o not make solder connections t o car- tridge terminals.

Cleaning

Use a camel's hair brush (No. 2 size o r smaller), trimmed to approximately 6 mm (1/4 in.) dipped i n alcohol o r an alcohol-distilled water solution.

Commercial cleaning solutions may cause stylus damage o r corrosion. The alcohol w i l l remove any sludge deposit coating the stylus tip. Always brush stylus from back to front; never brush o r wipe stylus from front to back o r side to side.

Easy

Replacement (see

Figure

2)

Grasp molded housing o f stylus between thumb and forefinger. Gently withdraw stylus by pulling forward out of cartridge. Grasp replacement stylus between thumb and forefinger and insert into sty- lus socket. Press stylus into socket until the molded housing of the stylus mates w i t h the cartridge case.

Care must be taken not to allow the finger to slip off the molded housing o f the stylus, resulting i n damage to the stylus t i p o r shank.

SPECIAL NOTE: To maintain .the original perform- ance standards of your cartridge, be certain that any replacement stylus you buy is precision manu- factured by Shure Brothers Inc. AVOID INFERIOR
