The Akai model AA-1030 , is another machine that's packed with power.
Minimum 30 watts per channel RMS at 8 Ω from 20 to 20,000 Hz with no more than 0,3% T.H.D. And frankly we're probably being over modest. It's certainly worth emphasising here that the power rating is a minimum. Typical samples, when measured with both channels driven at 1 kHz into 8 Ω , should demonstrate quite clearly the importance of comparing specification in power output.
There's a delicately balanced flywheel for picking your spot on the waveband. And with AFC (Automatic Frequency Control) you get perfect FM centre tuning with completely drift-free reception. A low noise FET and 3-gang frequency rectilinear variable capacitor in the front end eliminate intermodualtion distortion for clear broadcast reception. Ceramic filters in the FM IF section give better reception of weak signals. IHF sensitivity is 2,0 µV. The Phase-Lock-Loop circuit produces complete stability with separation better than 40 dB
As with the AA-1020, the AA-1030 also has variable FM muting to let you select not only the strongest stations and the weakest stations the tuner can pick up, but any point in between as well. There's also a level adjuster to allow you to cut out local atation interference. There are separate bass and treble tone controls; loudness switch; high and low filters; the same comprehensive tape dubbing facilities as the AA-1020 (you can connect two tape decks for simultaneous recording from a single source and Tape monitor 1 has parallel DIN and phone connections), two sets of phono jacks; aux jacks; connections for two speaker systems; FM and AM antenna terminals and a distance/local switch.
