They can not be used to equalize channel outputs or as Frequency Response cassettes.Suitable for tape speed alignment of Cassette Tape Decks using Frequency Counter and W&F Meter.Only new TDK, MAXELL or TEAC 17u tape is used when recording.Time Constant: 3180us + 120us. Frequency: 1 kHz, 3 kHz or 3.15 kHz. Frequency fluctuation: +/-0.01% measured.Level: -10 dB re 0 dB 160 nWb/m @ 400 Hz for 3 kHz NAB tapes (Nakamichi DA09006A); -10 dB re 0 dB 250 nWb/m @ 315 Hz for 3,15 kHz DIN tapes; -10 dB re 0 dB 250 nWb/m @ 315 Hz for Tandberg 1 kHz DIN tapes. Duration: 5 min recorded at the BEGINNING of the Tape from 00 min 30 sec to 5min 30 sec;The residual W&F of the tape itself is 0.022 % RMS WEIGHTED measured to NAB / JIB C5551 Standards using for playback the same MX5050 Reel to Reel tape recorder the tape has been recorded on. A few measurements of the same tape portion have been done using a Neutrik A2 analizer. The results from 0.008% to 0.036% averaged to 0.022%. A cassette reproduced using our Nakamichi Dragon showed 0.014% to 0.057% averaged to 0.035%. Cassette Tape Deck speed alignmentThe tape frequency reading gradually drops slowly towards the end of 5 min. portion of the tape. This is normal, and it depends on the deck mechanism condition. To check your deck mechanism condition do following: 1. Read the deck Speed specifications (1-7/8 +/- ….%). 2. Calculate +/-….Hz tolerance from 1000, 3000 or 3150 Hz. 3. Playback ANY tape for 2 minutes to warm up motors and mechanism. 4. Playback the 1, 3 or 3.15 kHz Speed tape from the beginning of the tape for 1 min. Note the frequency in Hz at the end of the 1 min. portion of the tape. Say this is the Frequency at the Beginning of the Speed tape. 5. Stop the deck. Flip over the cassette. The 1 min. portion becomes the last minute of the tape. 6. Playback the tape from that 1 min. position and note the frequency in Hz at the beginning of that 1 min. portion of the tape. Say this is the Frequency at the End of the Speed tape. 7. Check if the frequency difference in Hz is within the decks Speed specifications tolerance. If not, a number of things could be the reason: too high back tension of the supply reel (dirty friction felt or misalignment), not enough friction in the capstan-pinch roller pair (dirty or dried out pinch roller), dried out capstan bearings lubrication, dried out and loose capstan belt, dried out motor bearings lubrication etc. 8. Finally, calculate the Average Frequency. F average = (F beginning + F end)/2. Calculate the Average Frequency Deviation from the Tape Nominal Frequency. Deviation = F average - F nominal. Adjust speed of the deck to obtain minimum possible Deviation.3kHz or 3.15kHz 1-7/8 4.76 cm/sec Speed Cassette is suitable for tape speed alignment of any Normal-speed Cassette Tape Deck (Nakamichi DA09006A).3kHz or 3.15kHz 15/16 ips 2.38 cm/sec Speed Cassette is suitable for tape speed alignment of any Low-speed Cassette Tape Deck (e.g. Nakamichi 680ZX).3 kHz or 3.15kHz 3-3/4 ips 9.53 cm/sec Speed Cassette is suitable for tape speed alignment of any Hi-speed Cassette Tape Deck.Tandberg Cass.

Cassette Tape Deck speed alignmentThe tape frequency reading gradually drops slowly towards the end of 5 min. portion of the tape. This is normal, and it depends on the deck mechanism condition. To check your deck mechanism condition do following: 1. Read the deck Speed specifications (1-7/8 +/- ….%). 2. Calculate +/-….Hz tolerance from 1000, 3000 or 3150 Hz. 3. Playback ANY tape for 2 minutes to warm up motors and mechanism. 4. Playback the 1, 3 or 3.15 kHz Speed tape from the beginning of the tape for 1 min. Note the frequency in Hz at the end of the 1 min. portion of the tape. Say this is the Frequency at the Beginning of the Speed tape. 5. Stop the deck. Flip over the cassette. The 1 min. portion becomes the last minute of the tape. 6. Playback the tape from that 1 min. position and note the frequency in Hz at the beginning of that 1 min. portion of the tape. Say this is the Frequency at the End of the Speed tape. 7. Check if the frequency difference in Hz is within the decks Speed specifications tolerance. If not, a number of things could be the reason: too high back tension of the supply reel (dirty friction felt or misalignment), not enough friction in the capstan-pinch roller pair (dirty or dried out pinch roller), dried out capstan bearings lubrication, dried out and loose capstan belt, dried out motor bearings lubrication etc. 8. Finally, calculate the Average Frequency. F average = (F beginning + F end)/2. Calculate the Average Frequency Deviation from the Tape Nominal Frequency. Deviation = F average - F nominal.

GennLab Standard Alignment Cassettes.1 kHz, 3 kHz or 3.15 kHz Speed, Wof & Flutter.Please note. These cassettes are 3 kHz FREQUENCY cassettes. They can not be used to equalize channel outputs or as Frequency Response cassettes.Suitable for tape speed alignment of Cassette Tape Decks using Frequency Counter and W&F Meter.Only new TDK, MAXELL or TEAC 17u tape is used when recording.Time Constant: 3180us + 120us. Frequency: 1 kHz, 3 kHz or 3.15 kHz. Frequency fluctuation: +/-0.01% measured.Level: -10 dB re 0 dB 160 nWb/m @ 400 Hz for 3 kHz NAB tapes (Nakamichi DA09006A); -10 dB re 0 dB 250 nWb/m @ 315 Hz for 3,15 kHz DIN tapes; -10 dB re 0 dB 250 nWb/m @ 315 Hz for Tandberg 1 kHz DIN tapes. Duration: 5 min recorded at the BEGINNING of the Tape from 00 min 30 sec to 5min 30 sec;The residual W&F of the tape itself is 0.022 % RMS WEIGHTED measured to NAB / JIB C5551 Standards using for playback the same MX5050 Reel to Reel tape recorder the tape has been recorded on. A few measurements of the same tape portion have been done using a Neutrik A2 analizer. The results from 0.008% to 0.036% averaged to 0.022%. A cassette reproduced using our Nakamichi Dragon showed 0.014% to 0.057% averaged to 0.035%. Cassette Tape Deck speed alignmentThe tape frequency reading gradually drops slowly towards the end of 5 min. portion of the tape. This is normal, and it depends on the deck mechanism condition. To check your deck mechanism condition do following: 1. Read the deck Speed specifications (1-7/8 +/- ….%). 2. Calculate +/-….Hz tolerance from 1000, 3000 or 3150 Hz. 3. Playback ANY tape for 2 minutes to warm up motors and mechanism. 4. Playback the 1, 3 or 3.15 kHz Speed tape from the beginning of the tape for 1 min. Note the frequency in Hz at the end of the 1 min. portion of the tape. Say this is the Frequency at the Beginning of the Speed tape. 5. Stop the deck. Flip over the cassette. The 1 min. portion becomes the last minute of the tape. 6. Playback the tape from that 1 min. position and note the frequency in Hz at the beginning of that 1 min. portion of the tape. Say this is the Frequency at the End of the Speed tape. 7. Check if the frequency difference in Hz is within the decks Speed specifications tolerance. If not, a number of things could be the reason: too high back tension of the supply reel (dirty friction felt or misalignment), not enough friction in the capstan-pinch roller pair (dirty or dried out pinch roller), dried out capstan bearings lubrication, dried out and loose capstan belt, dried out motor bearings lubrication etc. 8. Finally, calculate the Average Frequency. F average = (F beginning + F end)/2. Calculate the Average Frequency Deviation from the Tape Nominal Frequency. Deviation = F average - F nominal. Adjust speed of the deck to obtain minimum possible Deviation.3kHz or 3.15kHz 1-7/8 4.76 cm/sec Speed Cassette is suitable for tape speed alignment of any Normal-speed Cassette Tape Deck (Nakamichi DA09006A).3kHz or 3.15kHz 15/16 ips 2.38 cm/sec Speed Cassette is suitable for tape speed alignment of any Low-speed Cassette Tape Deck (e.g. Nakamichi 680ZX).3 kHz or 3.15kHz 3-3/4 ips 9.53 cm/sec Speed Cassette is suitable for tape speed alignment of any Hi-speed Cassette Tape Deck.Tandberg Cass.
