Introduction

This manual provides essential information for the proper setup, operation, and maintenance of your Denon DP-450USB Semi-Automatic Analog Turntable. Please read this manual thoroughly before using the product to ensure optimal performance and longevity.

1. Setup

1.1 Unpacking and Component Identification

Carefully remove all components from the packaging. Ensure all items listed below are present:

• Turntable Unit
• Dust Cover
• USB Cable
• Power Adapter
• Platter
• Drive Belt (pre-installed or separate)
• Counterweight
• Headshell with Cartridge (pre-mounted)
• 45 RPM Adapter

1.2 Placement

Place the turntable on a stable, level surface away from direct sunlight, heat sources, and strong vibrations. Ensure adequate ventilation around the unit.

1.3 Platter and Belt Installation

1. Carefully place the platter onto the center spindle.
2. Locate the drive belt (if not pre-installed) and stretch it around the inner rim of the platter and over the motor pulley.

1.4 Tonearm and Cartridge Setup

The DP-450USB typically comes with a pre-mounted cartridge. Follow these steps for tonearm balancing:

1. Remove the stylus protector.
2. Unlock the tonearm from its rest.
3. Adjust the counterweight by rotating it until the tonearm is balanced and floats horizontally.
4. Set the tracking force according to the cartridge manufacturer's specifications (typically 1.8g for the included cartridge).
5. Adjust the anti-skating dial to match the tracking force setting.

1.5 Dust Cover Installation

Attach the dust cover hinges to the designated slots on the rear of the turntable. The unique design allows the dust cover to double as a display stand for album covers.

1.6 Connecting to an Audio System

The DP-450USB offers multiple connectivity options:

• Analog Output (RCA): Connect the RCA cables from the turntable's 'PHONO OUT' to your amplifier's phono input. If your amplifier lacks a phono input, use the built-in phono equalizer by setting the 'EQUALIZER' switch to 'ON'.
• USB Output: Connect the USB cable to your computer for digitizing vinyl records.

3. Maintenance

3.1 Cleaning the Stylus

Gently brush the stylus from back to front using a soft brush designed for stylus cleaning. Avoid touching the stylus with your fingers.

Wipe the turntable chassis and platter with a soft, dry cloth. For stubborn marks, use a slightly damp cloth and dry immediately. Avoid abrasive cleaners or solvents.

3.3 Dust Cover Care

Clean the dust cover with a soft, lint-free cloth. Use a mild, non-abrasive cleaner if necessary. Avoid harsh chemicals that can scratch or cloud the plastic.

4. Troubleshooting

• No Sound: Check all cable connections (RCA, power). Ensure the phono equalizer switch is set correctly (ON if connecting to a line-level input, OFF if connecting to a phono input). Verify amplifier and speaker settings.
• Skipping or Distortion: Check if the record is clean and free of dust. Verify tonearm balance, tracking force, and anti-skating settings. Ensure the turntable is on a stable, level surface.
• Incorrect Speed: Confirm the speed selector switch is set to the correct RPM for the record being played.
• USB Recording Issues: Ensure the USB cable is securely connected and your recording software is correctly configured to recognize the turntable as an audio input device.
