QUICK-START

Turntable Quick-Start:

1. Changing Platter Speed

Use the RPM selectors (10 & 11) to change the platter speeds. The 33-rpm (10) and 45-rpm (11) speed selectors change the platter rotation respectively.

2. Starting and Stopping the Platter

Use the START/STOP BUTTON (6) to switch back and forth between platter rotation and pause modes.

3. Pitch Control

1. The pitch adjustment is a fine adjustment to the platter's RPMs.

2. The pitch adjustment is variable and may be adjusted between -10% and +10% of the platter selected speed.

3. The pitch is changed by sliding the Pitch Slider (12) in an up and down motion.

4. The STROBE INDICATORS (2) on the rim of the PLATTER (20) can be used to visual approxi- mate the platter pitch. These indicators are lit by the STROBE INDICATOR PILOT LAMP (4) as they pass by the POWER SWITCH (5). At different pitch levels each row of STROBE INDICATORS (2) may appear stand still.

Note: The use of heavy fluorescent lighting directly above the turntable will defeat the STROBE LAMP PILOT LAMP (4) affect indicator accuracy.

Product Service:

1. Clean the stylus periodically with a soft brush to prevent the accumulation of dust.

2. When sound becomes distorted or noisy, check the stylus. If the stylus is worn out, replace it with a new one.

3. From time to time, the dust cover and turntable cabinet should be wiped down with a soft, dry cloth.

4. Volatile materials should not be used, such as: alcohol, thinner, benzine etc. They may remove the paint or damage the luster.

Turntable Installation:

1. Do not place the unit in a location where it will be exposed to direct sunlight or near any type of heating appliance.

2. Do not place the unit in a location where there is high humidity or a lot of dust.

3. Cartridge may pick up slight sound pressure or vibrations of near by speakers. For best results, do not install this unit too close to speakers.

4. Install this unit on a horizontal surface that is stable and vibration free.

5. The rubber feet have been specially designed to isolate the unit from excess vibration. The feet may also be used to stabilize the main body horizontally. Adjust the height of the unit by turning the feet in a clockwise or counter-clockwise direction.

Tonearm Balance and Stylus Pressure:

Adjustment of horizontal zero balance and stylus pressure:

1. Remove the stylus protective cover, if so equipped. Never touch the stylus tip during the adjust ment.

2. Lower the TONEARM LEVER (13).

3. Release the tonearm clamp and release the tonearm from the arm rest.

4. Set the ANTI-SKATE (15) adjustment to zero.

5. Rotate the COUNTERWEIGHT (16) in either direction until the TONEARM (9) is perfectly balanced

horizontally (floats freely).

6. Return the TONEARM (9) to the arm rest and lock it in place.

7. Hold the COUNTERWEIGHT (16) stationary with one hand and rotate only the stylus-pressure ring to bring the number “0” of the ring into alignment with the center line on the tonearm rear shaft.

8. Rotate the COUNTERWEIGHT (16) clockwise until the scale value corresponding to the recom mended stylus pressure.

Note: The recommended stylus pressure of the optional cartridge that may have been included with

your unit is 2 grams. For all other cartridge systems please refer to the manufactures specification included with the cartridge.

Anti-Skate:

The anti-skate adjustment prevents the TONEARM ASSEMBLY (9) from skipping across the record from the centrifugal force that is caused spinning rotation of the PLATTER (20). The ANTI-SKATING

(15) control knob should be set to the same value as the stylus pressure. For example if your COUNTERWEIGHT (16) is set to 2.5 grams the ANTI-SKATE (15) value should also be set to 2.5.

The included HEADSHELL (7) is used to connect your stylus with the tone arm.

After attaching the headshell to the tonearm, this locking nut will securely hold the headshell to the tonearm.

The tonearm is the mechanism that holds the HEAD- SHELL (7) and stylus allowing it to glide across a record.

Engaging this button will rotate the platter at 33 revo lutions per a minute (RPMs). A function LED will glow when this function is activated.

Engaging this button will rotate the platter at 45 RPMs. A function LED will glow when this function is acti vated.

This slider is used to adjust the playback pitch per

centage (platter speed). Use this slider to match the BPM’s of this unit to that of another music source.

This lever is used to safely elevates the tone arm above a record surface without endangering a records surface.

The anti-skate applies inward force to the tonearm to prevent outward skipping across the record due to the centrifugal force cause by platter rotation. The antiskate value should be equally to that of the stylus counterweight pressure (see counterweight 16).

The counterweight adjustment applies the proper downward pressure on the stylus.

This cut out has been designed to safely store an extra stylus headshell.

These jacks are used to send a low voltage "phono" level output signal to a mixers "phono" input jacks. Turntables should only be connected to “Phono” inputs on a mixer. The red colored RCA jack repre

sents the right channel input and the white represents the left channel input.
