NOTE:
Specifications and the design subject to possible modifi-
cation without notice due to improvements.
NOTES:
1. Reference Tapes: Standard & LH: DIN 45513/BLATTE6 or
equiv.
: CrO,: DIN 45513/BLATT7(CrO, ) or equiv.
. Reference Recording Level: Meter OdB indicating level (160
nwb/m magnetic level = Philips cassette reference level)
. Reference Signal: 333Hz
. Wow & Flutter: e JIS [3kHz, with acoustic compensation
(weighted), rms value]
5. Frequency Response: @ Measured at —20dB level, DOLBY
NR OFF, level deviation is $6dB without indication.
6. Signal to Noise Ratio: @ Measured at the third harmonic distor-
tion 3% level, weighted. e
7. Sensitivity: Input level (mV) required for reference recording
level with input (REC) controls set to maximum.
8. Maximum Allowable Input: While decreasing settings of input
(REC) tevel controls and increasing level at input jacks, this is
the maximum input level (mV) at the point where recording
amplifier output waveform becomes clipped.
9. Reference Output Level: Playback output level when meter
indicates OdB.
10. Maximum Output Level: Playback output level with respect to
reference recording level when output (PLAY) level controls
are set to maximum.
