Setup

Follow these steps carefully for proper assembly and initial setup of your Marantz TT-15S1 turntable.

1. Turntable Placement

Place the turntable chassis on a stable, level surface, away from direct sunlight, heat sources, and excessive dust. The three height-adjustable aluminum feet provide a strong base and can be adjusted to ensure the turntable is perfectly level.

2. Motor Assembly and Placement

The external motor unit is designed to minimize vibration transfer to the plinth. Place the motor unit next to the turntable chassis, ensuring it is stable. Attach the motor pulley to the motor shaft. Some users find placing a 2-inch circular felt pad under the motor can further reduce vibration and optimize belt alignment.

3. Platter and Belt Installation

Carefully place the turntable platter onto the center shaft. Using the provided white cotton gloves to avoid fingerprints, gently loop one of the silicon drive belts around the motor pulley and the outer rim of the platter. Ensure the belt is seated correctly and not twisted.

4. Tonearm and Cartridge Installation

The anodized aluminum tonearm is a critical component for sound quality. Attach the ClearAudio Virtuoso MM cartridge to the headshell using the provided screws. Connect the four delicate wires from the tonearm to the corresponding pins on the cartridge (Red-Right Hot, Green-Right Ground, White-Left Hot, Blue-Left Ground). Use tweezers for precision. Secure the headshell to the tonearm.

5. Tonearm Adjustment (Tracking Force and Anti-Skate)

Accurate tonearm adjustment is crucial for optimal sound and record longevity. First, balance the tonearm so it floats freely. Then, set the tracking force using the counterweight according to the cartridge manufacturer's recommendation (typically 1.8-2.2 grams for the Virtuoso MM cartridge). Use a stylus force gauge for precise measurement. Finally, adjust the anti-skate mechanism to prevent the stylus from pulling towards the center or outer edge of the record. A test record can be used for fine-tuning this setting.

6. Connecting to an Amplifier/Receiver

Connect the turntable's audio cables to the "Phono" input of your amplifier or receiver. Ensure both the audio ground cable from the tonearm and the separate 5' ground wire from the turntable chassis are connected to the signal ground terminal on your amplifier to prevent hum. If your amplifier does not have a dedicated "Phono" input, a separate phono pre-amplifier (MM compatible) will be required.

Operating the Turntable

Once set up, operating the Marantz TT-15S1 is straightforward.

1. Powering On/Off

Plug the motor's AC power cord into a suitable wall outlet or power strip. The turntable does not have a dedicated power switch on the unit itself; it is designed to be powered on/off via the wall outlet or a switched power strip. This allows the motor to run continuously for optimal speed stability, or to be easily turned off when not in use.

2. Selecting Playback Speed

The TT-15S1 supports two playback speeds: 33 1/3 RPM and 45 RPM. To change speed, manually move the drive belt to the appropriate groove on the motor pulley. The smaller diameter groove is for 33 1/3 RPM, and the larger diameter groove is for 45 RPM.

3. Playing a Record

1. Place a record on the platter. You may use the included felt turntable pad.
2. If desired, place the record clamp (Clever Clamp by Souther Engineering) over the record spindle to flatten the record and reduce vibrations.
3. Gently lift the tonearm using the cueing lever.
4. Position the tonearm over the desired starting groove of the record.
5. Slowly lower the cueing lever to gently drop the stylus onto the record.
6. At the end of playback, lift the tonearm using the cueing lever and return it to the tonearm rest.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your turntable.

• Cleaning the Plinth and Platter: Use a soft, dry, lint-free cloth to wipe down the acrylic plinth and platter. Avoid abrasive cleaners or solvents.
• Stylus Cleaning: Gently clean the stylus regularly using a dedicated stylus brush or cleaning fluid. Always brush from back to front.
• Drive Belt Inspection: Periodically inspect the drive belts for signs of wear, stretching, or cracking. Replace them if necessary to maintain accurate playback speed.
• Bearing Lubrication: Apply a small drop of the provided bearing oil to the main platter bearing shaft periodically, as instructed in the original packaging or by Marantz support, to ensure smooth rotation.
• Dust Cover: While not included, consider acquiring a dust cover to protect the turntable from dust and debris when not in use.
