Our Dynamic Master uses a refined cobalt ferric mix for a wide dynamic range and low noise. It is the most sought-after standard bias formula for clients who require high-quality voice and music recording. The cassette tapes are bulk-loaded without a Norelco box, label, or J card.

Features:

• Type: 5 Screws Type I Normal Bias Master Audio Cassette.
• Packaging: No case or label. Cassettes come in a 25-pack box.

We do not accept the return of all custom-loaded audio tapes. No technical data is available for reference, and we cannot guarantee a specific dB or frequency (Hz). We only purchase high-performance ferric oxide material formulated for demanding music applications. It meets all the requirements for music recordings.
