DISTORTION
Recorded on 280B using 3M 206 tape,
3rd harmonic distortion of 500-Hz signal
at 500 nWb/m is less than 3%; at
standard operating level (250 nWb/m) is
less than 0.6%. Speaker out 1% at
3.0 Watts into 8-0hm resistive load.
OUTPUTS Line +17 dBm into 600-0hm load. Speaker
3.0 Watts into 8-0hm resistive load.
EQUALIZATION Automatically switched with transport
speed. Specify NAB or IEC (CCIR).
*Full track and two track only. Quarter track approximates same
response. Measurements available on request.
