Signal to Noise Ratio:
| Tape Speed | Overall Record/Playback Unweighted | Playback Only Electronics (at all speeds) |
|---|---|---|
| 15 ips | 66 dB | 72 dB unweighted |
| 7½ ips | 66 dB | |

Measured with respect to a record level of 520 nWb/m to biased tape noise when using Ampex 456 or 3M 250 tape, using a 30 Hz to 18 kHz audio filter. Playback only measured with a 30 Hz to 18 kHz audio filter.
Crosstalk: At 1000 Hz on adjacent tracks: greater than 55 dB.
Frequency Response:
| Tape Speed | Overall Record/Playback | Playback Only |
|---|---|---|
| 15 ips (at 0 VU, +4 dBm) | 30 Hz to 22 kHz (±2 dB) | 31.5 Hz to 20 kHz (±2 dB) |
| 7½ ips (at -10 VU, -6 dBm) | 25 Hz to 20 kHz (±2 dB) | 31.5 Hz to 16 kHz (±2 dB) |
| 3¾ ips (at -10 VU, -6 dBm) | 30 Hz to 12 kHz (±2 dB) | 31.5 Hz to 10 kHz (±2 dB) |
Overall record/playback based on 250 nWb/m alignment level and 3M 206. Playback only using an MRL 21J205 alignment tape.
Distortion: Less than 0.7% at 1000 Hz at 250 nWb/m.
Test Oscillator Frequency: Nominal 1000 Hz.
Indicators: Standard VU meters plus peak reading LED's set at +9 dB (adjustable) based on 185 nWb/m.
