Setup
To prepare your Maxell XL-II 90-Minute audio cassette for use, follow these steps:
- Compatibility Check: Ensure your cassette deck or recorder supports Type II (High Bias / CrO2) audio cassettes. Using a Type II cassette in a deck not configured for it may result in suboptimal recording or playback quality.
- Unpack the Cassette: Carefully remove the cassette from its packaging.
- Labeling: Use the provided labels or a permanent marker to clearly identify the contents of your recording on the cassette shell and J-card.
- Tape Slack Adjustment: Before inserting, ensure there is no slack in the tape by gently inserting a pencil or similar object into one of the hub holes and turning it clockwise until the tape is taut.
Operating Instructions
This section outlines the general procedures for recording and playing audio on your Maxell XL-II 90-Minute cassette.
Recording Audio
- Insert Cassette: Open the cassette compartment of your deck and insert the Maxell XL-II cassette with the desired side (A or B) facing up, ensuring the tape window is visible. Close the compartment securely.
- Select Bias Setting: On your cassette deck, select the 'Type II' or 'High Bias' setting. Some decks may automatically detect the tape type.
- Set Recording Levels: Connect your audio source (e.g., CD player, turntable, computer) to the input jacks of your cassette deck. Adjust the recording level controls to ensure the audio signal does not peak into the red zone on the deck's meters, which can cause distortion. Aim for levels that are consistently high but avoid clipping.
- Begin Recording: Press the 'Record' and 'Play' buttons simultaneously (or as per your deck's instructions) to start recording. Begin playing your audio source.
- Monitor Recording: Continuously monitor the recording levels and sound quality during the process.
- Stop Recording: Press the 'Stop' button on your deck when finished.
- Protect Recording: To prevent accidental erasure, break off the small plastic tabs located on the top edge of the cassette for the recorded side.
Playing Audio
- Insert Cassette: Insert the recorded Maxell XL-II cassette into your deck.
- Select Playback Settings: Ensure your deck's playback settings (e.g., Dolby Noise Reduction, EQ) are appropriate for the recording.
- Start Playback: Press the 'Play' button.
- Adjust Volume: Adjust the volume on your amplifier or receiver to your desired listening level.

Maintenance
Proper care of your Maxell XL-II cassettes will ensure longevity and optimal performance.
- Storage: Store cassettes in their cases, away from direct sunlight, high temperatures, humidity, and strong magnetic fields (e.g., speakers, motors).
- Handling: Avoid touching the magnetic tape surface. Handle cassettes by their edges.
- Cassette Deck Maintenance: Regularly clean the heads, capstan, and pinch roller of your cassette deck to prevent tape wear and maintain sound quality. Demagnetize the heads periodically.
- Avoid Dropping: Do not drop cassettes, as this can damage the shell or internal components.
Troubleshooting
If you encounter issues with your Maxell XL-II cassette, consider the following:
- Poor Sound Quality (Dull/Muffled):
- Ensure your cassette deck's bias setting is correctly set to Type II (High Bias).
- Clean the cassette deck's heads and pinch rollers.
- Check if the recording levels were set too low during recording.
- Distorted Sound:
- Recording levels may have been set too high, causing clipping. Re-record with lower levels.
- Check for damage to the tape or cassette shell.
- Tape Jamming or Snapping:
- Ensure the tape is taut before insertion (no slack).
- Check for physical damage to the cassette shell or tape.
- Clean and inspect your cassette deck's transport mechanism for obstructions or worn parts.
- No Recording Occurs:
- Verify that the record-protection tabs on the top edge of the cassette are intact. If they are broken off, cover the holes with adhesive tape to enable recording.
- Ensure your cassette deck is in record mode (usually by pressing 'Record' and 'Play' simultaneously).
