Congratulations on your new Huldra
We hope that the unit will serve you faithfully for many years and bring you joy every day. Huldra
has a lot of features, but if you take it step by step, you will see that it is quite manageable. Huldra
can reproduce programs from 5 different sources:
1.
AM radio, i.e., long wave, medium wave, coastal wave and short wave.
2.
FM radio.
3.
Tape recorder, mono or stereo.
4.
Turntable, mono or stereo. A separate 2-channel pre-amplifier with 4 transistors will
ensure full utilization of the power amplifier with the use of magnetic pickup. The pre-amp
has a selector with correction curves for magnetic, ceramic or crystal pickup.
5.
From the “listen and talk” function, which enables communication with people
in other
rooms.
Huldra 8 is prepared for FM stereo multiplex reception. The main circuit board has dedicated
space and connection points for a decoder for your particular FM stereo system. A separate
indicator light will light up on stereo sound reproduction.
Huldra 8 has 2 transistorized main amplifiers (class B
1
). Both amplifiers can be used in parallel for
the same program, or independently for two mono programs or one stereo program. The two
amplifiers (channels) have individual volume control. Max. output power is 2 x 10 Watt.
