The Akai AA-1020
Promises a minimum power output of 20 watts per channel RMS at 8 ohms from 20 Hz to 20 khzs with no more than 0,4% total harmonic distortion. IHF tuner sensitivity is 2,0 µV.
The Multiplex Section features a Phase-Lock-Lop circuit which locks the 19 kHz FM sugnal phase to the phase of the 38 kHz switching signal for complete stability. Separation is better than 40 dB. An FM Muting switch cuts out noise during FM reception.
There's a power transistor protection unit which is activated if there's a short caused by a wrong speaker connection or when input goes over the top. The tone control circuit is a 2-stage direct coupled negative feedback type. It gives you precise tone adjustment of both channels Special "click: type Bass and Treble controls can be adjusted to plus or minus 10 dB. Each calibrated "click" represents 2 decibels. A two stage direct coupled negative feedback phono equalizer circuit provides a really wide dynamic range from disc.
The loudness switch boosts bass and treble response for balanced sound at low volume. High and low filters reduce extreme high and low frequency output for clearer playback quality.
There's a comprehensive tape dubbing facility as well. You can connect two tape decks for simultaneous recording from a single source. Tape monitor 1 has parallel DIN and phone connections. You can also connect up two pairs of speakers. A Speaker Selector gives you the choice of using the speakers individually or both together.
The AA-1020 has both FM and AM antenna terminals and a distance/local switch plus an AM Bar antenna for perfect station pick-up.
Versatility goes still further with two sets of phono jacks for connecting two magnetic cartridge turntables. Aux jacks will take ceramic and crystal cartridge turntables. And the Aux jacks can also be used for dubbing from an additional tape recorder to Tape 1 or Tape 2.
