Output Facilities:
4 loudspeakers to DIN 41 529 (Impedance 4 Q.
a)
Minimum impedance 3.2 Q) for stereo in two
separate rooms. It is permissible
loudspeakers with an impedance Of up to 16 Q
provided that the associated loss in output
power can be tolerated. The amplifier
fitted with an automatic short circuit
device which comes into operation when the
output load falls below 1.5 Q.
b) 2 sockets to DIN 45 Q7 for connecting
Of stereo headphones. Output impedance in the
range 5 to 2000 Q.
c) Line output: 410 mV in 47 kQ for 500 mV on
Tape input. mV in 47 kQ for 5 mV on
Phone input. Ri 5.6 kQ. Short-circuit
connecting tape recorders. amplifiers
units with corresponding input socket.
Damping Factor:
The internal impedance Of the amplifier
and when connected to a 4 Q load this will give
a damping factor of dB. This damping factor is
improved when using loudspeakers Of a higher
impedance.
