Kenwood's KA-7100 integrated amplifier is a moderate-price product with outstandingly low distortion specifications and ample control flexibility for a well-equipped hi-fi system. It is rated to deliver 60 watts per chanhel to 8-ohm loads from 20 to 20,000 Hz, with less than 0.02 per cent total harmonic distortion. The KA-7100 has separate power supplies for its two channels, fed by a common power transformer. The power-amplifier sections of the KA-7100 are direct-coupled.
The dominant feature of the front panel is the large volume-control knob near its center. It operates a thirty-two-position step attenuator whose detents are so light that one is hardly aware of their presence. The bass and treble tone controls are each eleven-position step controls, and the balance control is lightly detented at its center. Below these are level switches for tone defeat, subsonic and high filters, and a 20-dB audio attenuator.
To the right of the volume knob is the tape switch, with positions for dubbing from one tape deck to another (but not back the other way) while monitoring the playback output from either deck and for conventional tape playback from either tape deck or a selected program source. The input selector has positions marked phono, tuner, and aux. Below are the loudness switch, with three positions marked off, 1, and 2, and the mode selector, with reverse, stereo, and mono positions. Completing the front-panel controls are the speakers switch at the upper left (for driving either, both, or neither of two pairs of speakers), the power switch, and a headphone jack.
In the rear of the amplifier are the various signal input and output jacks, plus a DIN socket duplicating one set of the tape-recorder connections. The speaker terminals are insulated binding posts. The two switched a.c. outlets will take no more than 100 watts of accessory equipment; there is one unswitched outlet. The Kenwood KA-7100 is approximately 17 inches wide, 15 inches deep, and 6 inches high. It weighs 25.4 pounds.
