Frequently Asked Questions - DJ Wheeler MARTIN

How do I replace the stylus on the DJ Wheeler?

To replace the stylus, gently remove the old stylus from the cartridge by sliding it forward. Align the new stylus with the clips and push until it clicks into place. Ensure the turntable is off before handling the cartridge.

Can I use this turntable with a digital DJ controller?

Yes, you can connect the DJ Wheeler to a digital DJ interface via the RCA outputs. You will need a compatible audio interface or mixer with phono inputs. Some setups may require a ground wire connection.

What is the pitch range on the DJ Wheeler?

The pitch control allows a range of ±8% and ±16%, with a reset button for returning to zero. Use the wider range for creative effects and beatmatching.

How do I adjust the tonearm tracking force?

First, set the counterweight to zero. Then rotate the weight until the tonearm balances horizontally. Finally, adjust the tracking force dial to the recommended range for your cartridge (typically 1.5-2.5g). Use a stylus force gauge for accuracy.

Is the DJ Wheeler suitable for scratching?

Yes, the high-torque direct drive motor and sturdy construction make it suitable for scratching and club use. The start/stop button and pitch control are optimized for turntablism.

How do I connect the turntable to a mixer?

Use the included RCA cables to connect the turntable's output to a phono input on your mixer. Ensure the grounding wire is connected to the mixer's grounding terminal to avoid hum. Do not use line inputs without a preamp.

What should I do if the turntable produces no sound?

Check the power supply, RCA connections, and ensure the cartridge is properly attached. Verify that the mixer or amplifier is set to the correct input and volume level. Test with known working cables and speakers.

How do I clean the turntable's slipmat?

Remove the slipmat and gently hand wash with mild soap and water. Allow it to air dry completely before replacing. Do not use harsh chemicals or machine wash.

Can I convert vinyl records to digital files using this turntable?

Yes, connect the turntable to a computer via an audio interface or USB converter. Use recording software to capture the audio. Many DJ Wheeler models support direct USB connection if equipped.

What is the weight of the turntable?

The DJ Wheeler weighs approximately 4.5 kg (10 lbs), making it stable for performance yet portable enough for transport. Check the packaging dimensions for shipping.

• Do not expose the fixture to rain or moisture.
• Refer all service to a qualified technician.
• Never operate the fixture with missing or damaged lenses and/or covers.

To protect yourself and others from burns and fire

• Never attempt to bypass the thermostatic switch or fuses. Always replace defective fuses with ones of the specified type and rating.
• Keep all combustible materials at least 0.1 meters (4 inches) away from the fixture. Keep flammable materials well away from the fixture.
• Do not illuminate surfaces within 0.3 meters (12 inches) of the fixture.

• Provide a minimum clearance of 0.1 meters (4 inches) around fans and air vents.

• Replace the lamp if it becomes defective or worn out. When replacing the lamp, allow the fixture to cool for at least 15 minutes before opening the fixture or removing the lamp. Protect your hands and eyes with gloves and safety glasses.

• Never place filters or other materials over the lenses or mirror drums.

Warning! Make sure the fixture is disconnected from AC power before removing the lamp box. Allow hot lamps to cool for 15 minutes before replacing.

1 Locate the lamp box with the four lenses in the center of the unit. Support it in one hand while removing the two thumbscrews on the top, and remove the lamp box.
2 Hold the lamp by the ceramic base or in a clean cloth, taking care not to touch the glass, and then push the lamp firmly into the lamp socket. If you do touch the glass part of the lamp you must clean it thoroughly with alcohol before use.
3 As you replace the lamp box, lead the wires through the corner opening so as not to pinch them. Replace the thumbscrews and tighten them securely by hand.

WARNING! The fixture must be grounded (earthed).

The fixture may be delivered without a plug on the power cord. A 3-prong grounding-type plug must be installed. Following the manufacturer's instructions:

1 Connect the BROWN wire to the LIVE pin.
2 Connect the BLUE wire to the NEUTRAL pin.
3 Connect the YELLOW/GREEN wire to the GROUND (EARTH) pin.

INSTALLATION

The fixture may be installed by fastening the mounting bracket directly to a structural support or with a rigging clamp.

WARNING! Always use an approved safety cable.

1 If using a rigging clamp, bolt the clamp to the bracket with an M12 bolt and lock nut through the 13 mm hole in the mounting bracket.
2 If fastening the bracket directly to the structure, make sure that the attachment hardware is adequate to hold the fixture securely.
3 Verify that the structure can support the weight of all installed fixtures, clamps, cables, auxiliary equipment, etc.
4 Working from a stable platform, fasten the fixture to the structure.
5 Install a safety cable that can hold at least 10 times the weight of the fixture through/over the support and through the mounting bracket.
6 Loosen the locks on both sides of the bracket and tilt the fixture to the desired angle. Tighten the tilt locks.

OPERATION

Important! Electric dimmers may damage the electronic components.

Do not attempt to dim the Wheeler. Use a suitable switch-pack or the 0 and 100 percent levels of a dimmer pack if you need to switch the fixture remotely.

To operate the Wheeler, apply power and set the mode switch to the “lamp on” or “flash” position. Sounds are picked up by a built-in microphone and an Automatic Gain Control circuit adjusts the gain when the average sound pressure alters.

LAMP ON

In “lamp on” mode, the lamp stays on and drum rotation is sound activated. If there is no sound, drum rotation stops.

FLASH

In “flash” mode, both the lamp and rotation are sound activated. If there is no sound, the lamp turns off after 5 seconds. There is no difference between the 2 “flash” positions.

FUSE REPLACEMENT

1 Disconnect the fixture from AC power.

2 Remove the fuse holder - located next to the power cord - with a flat-tip screwdriver.

3 Replace the fuse with one of the same size and rating. The rating is shown on the serial number label.

4 Replace the fuse holder.
