Instructions

Mounting: The stylus/cantilever assembly is the most fragile part of any phono cartridge. Please use extreme caution while handling the cartridge and keep the stylus guard mounted whenever possible to prevent damage during the mounting process.

Blue Point Special EVO III note: The Blue Point Special EVO III is supplied without a stylus guard so extra care must be observed when handling. Because of the likelihood of damaging an exposed generator cartridge during the process of removing and reinstalling the stylus guard, the stylus guard has been omitted from this model. When mounting a Blue Point Special EVO III, take care not to touch the semi-exposed wires leading from the four gold plated bars to the coil structure. These wires are very fragile and can be easily broken. Since it is not necessary to touch the cartridge where the wires are exposed, the mounting process will not be affected in any way. We suggest that you hold the Blue Point Special EVO III by either the blue top plate or the black rear plate of the cartridge during the mounting process. Using the supplied hardware, loosely mount the cartridge on the headshell. With a pair of small needle-nose pliers, connect the tonearm (headshell) lead wires to the cartridge terminal posts using the following orientation: Red wire to Right +, Green wire to Right −, White wire to Left + and Blue wire to Left −.

Do not solder the leads to the cartridge terminals as excessive heat may permanently damage the cartridge.

Once the cartridge is mounted, balance the tonearm for the proper vertical tracking force indicated for each model cartridge (see specifications at the end of this manual). To set the tracking force, first balance the tonearm. Locate the counterweight. On virtually all pivoted tonearms, it will be located at the rear of the tonearm (meaning at the opposite end from the cartridge). Generally, it looks like a fairly large, shallow cylinder, usually black in color and often has numbers (indicating grams of force) ranging from 0 to 3 or more printed on it. As you move the counterweight backwards, the cartridge end of the arm will lighten (reducing stylus tracking weight), while moving the counterweight forward will increase the stylus

tracking weight. The first objective is to "statically balance" the arm, which is to achieve the proper weight balance such that the arm "floats" level. Practice a bit and you'll find it's fairly easy to achieve. Remember to exercise caution so that the stylus and cantilever are kept clear of any obstructions and are prevented from striking anything that could cause damage. After achieving static balance, adjust the counterweight to the desired tracking force by bringing the weight in toward the cartridge. Do not apply anti-skate until the cartridge is aligned. This will be addressed later in the setup process.

We recommend the use of a high-quality alignment protractor to determine correct cartridge positioning for the minimum tracking error. If none are available, follow the tonearm manufacturer's guidelines for overhang and offset angle. Then, tighten the mounting bolts.

Note: Do not over tighten the mounting bolts as this may cause damage to the cartridge and is not necessary for optimum performance.

Tracking Force: After achieving the correct alignment of the cartridge in the headshell, final adjustment of tracking force can be made. The suspension systems and stylus types used in Oyster™ cartridges are designed to perform optimally when a tracking force of between 1.7 – 2.3 grams is applied, depending on which model. If under 1.7 grams tracking force is applied, the stylus will not securely seat in the record groove, resulting in increased record and stylus wear. At greater than 2.3 grams tracking force, the suspension is no longer functioning properly and dynamics will be lost. Record damage will occur more readily with too little tracking force, rather than too much. A recommended optimum tracking force setting is given for each model in the specification section of this manual.

Anti-Skate/Bias: Due to the rotational inertia of pivoted tonearms, the friction of the stylus on the record groove produces a force pulling the stylus toward the center of the record. Anti-Skate (or mechanical bias) is added to compensate for this force in order to equalize the stylus tracking on the sides of the groove walls. Because this is a dynamic force, do not attempt adjustment using a blank or grooveless record, as this will result in over compensation.

Because anti-skate is based on the mass and compliance of the cartridge design, the amount applied can be quite a bit different for the varying designs available. The Oyster™ Series moving coil cartridges (Blue Point No. 2 and Blue Point Special EVO III) are lower compliance and higher mass designs and are less affected by the vector force applied by playing a record. For this reason, when using one of these cartridges a value of roughly one half that of the tracking force is the ideal value. In other words, the Blue Point Special EVO III has an ideal tracking force of 2.0 grams. Therefore, the anti-skate value on your tonearm should be set to 1.0 – 1.5.

Vertical Tracking Angle/Stylus Rake Angle: The dimensions of the cutting stylus used in mastering each vinyl record create a rake (forward-backward tilt) of the record groove. The rake angle may change for different records depending on the method of mastering used. The corresponding rake of the playback stylus will be one of the determining factors in the delivered performance of your Oyster™ cartridge; however, all Oyster™ cartridges are designed to give excellent performance over a very wide window of rake angles. If your tonearm does not have rake or adjustable height adjustment, you may rest assured that your cartridge will deliver a very high degree of performance. The following is intended for those who own a tonearm that allows for the adjustment of rake or arm pillar height. To optimize, start with the tonearm oriented with the back of the arm lower than the front by ≈ 1/2 inch. Listen to a recording of acoustical music, recorded in real space, to determine the tonal balance and soundstage presentation. Adjust the tonearm pivot height upwards ≈ 1/6 inch at a time and listen to the changes. When the correct orientation has been achieved, the soundstage will be better defined and the music will have a richer harmonic structure. Additionally, surface noise will be reduced dramatically. If the soundstage comes into focus and becomes very lifelike, but the sound has a slight hardness to the upper frequencies, the azimuth is probably misaligned (see azimuth section for adjustment details).

Azimuth: For optimum tracking of the record grooves, the stylus must be in correct azimuth (side-to-side tilt) alignment. Gross side-to-side tilt will result in an actual channel imbalance, but this is not a likely

scenario. More likely, any sort of an azimuth error that you will experience will result in tonal aberrations in the upper frequencies and not a channel imbalance.

Loading: All Sumiko Oyster ^™ high output moving coil cartridges are designed to work into a standard moving magnet phone stage at 47kΩ loading. It is normal to experience a slightly lower output from your phono stage relative to a line stage device such as a CD player. Our low output MC cartridges have a recommended loading of 100 - 1kΩ.

Note: If your receiver or pre-amp has capacitance loading capabilities, a Sumiko high output moving coil cartridges should be loaded with a value no higher than 200pf, and ideally below 100pf.

Maintenance Cleaning: Optimum performance can only be achieved by maintaining a clean stylus and record surface. If your records are kept very clean, the brush supplied with your cartridge will suffice to remove accumulated dust if it is used after each play. Be sure to either turn the volume down or select a different input prior to doing this. Only use a back to front motion when contacting the stylus during cleaning. To remove compacted debris, we recommend LAST cleaning products as the best and safest stylus cleaner available.

Important: Extreme caution should be exercised in cleaning the stylus. A single front to back motion can permanently damage the cantilever.

Flux Build-Up: Any phono cartridge that comprises a magnetic circuit for generating electricity is subject to an unwanted magnetic flux build-up (bias). We have designed the cartridges in the Oyster™ Series to be less susceptible to this bias than other cartridge designs currently available. Symptoms of a charged cartridge are: distortion unrelated to tracking, a loss of dynamics, a loss of soundstage definition, or frequency related abnormalities. This can occur either gradually or rapidly, depending on the cartridge design type. While the Oyster™ Series cartridges are less susceptible to the flux build-up that other designs, the cartridge performance can be improved with the use of a cartridge demagnetizer. NEVER USE A TAPE HEAD OR BULK DEMAGNETIZER to demagnetize your Oyster™ series phono cartridge. Permanent damage will result with a significant loss of output. This cannot be reversed. (When using a cartridge demagnetizer on your Oyster™ moving magnet cartridge, the stylus assembly must be removed prior to the demagnetizing process or permanent damage will occur).

Stylus Replacement: Moving coil cartridges must be traded-in for a new unit as the stylus/cantilever assembly is not user replaceable. Some manufacturers offer something called a re-tip for moving coil cartridges. While the stylus tip is one component of the cartridge that wears out, so does the cantilever and rubber suspension system. Additionally, magnet power reduces over time as well. Replacing all of this is too costly a proposition and does not let the consumer take advantage of design updates that may not be retrofittable to their older cartridge. For these reasons, Sumiko provides both a cartridge trade-in and trade-up program. Some Oyster™ cartridge models can be upgraded to even higher performance models at additional cost to the consumer. See your dealer for more details.
