** Now with 4 reel options, default is a refurbished small hub reel**

The RTT-2 is a 3.75ips full track master recording test tape that will allow for the complete adjustment of azimuth, reproduce level and high frequency equalization as well as verifying frequency response characteristics. This tape can be used with full track, 2 track and 4 track recorders.

The tape includes our exclusive Toggle Tone test signal for easy high frequency adjustment. Our high accuracy process insures consistency and conformity to NAB standards. A convenient usage tally is provided to track play back passes. Each tape is serial numbered and has an associated QC report.
