Akai AA-1115 receiver

Stereo Receiver AA-1115

Outstanding performance is guaranteed from this elegantly designed slim high fidelity stereo receiver. Top grade circuitry, precise controls and multiple connections.

 

Quality Circuits for High Fidelity

A plus/minus power supply and differential semi-complementary OCL circuitry not only provides 15 watts per channel continous power output, minimum RMS at 8 ohms from 40 to 20,000 Hz with no more than 0,5% Total Harmonic Distortion, but also produces better phase characteristic and accounts for more low range frequency directivity. Top grade 3-stage direct coupled negative feedback equalizer circuit also in the amplifier section extends phono input, signal linearity to 110 mV (rms, 1 kHz) to assure wide dynamic range.

AA-1115 tuner section features PLL (Phase Locked Loop) MPX section to assure accurate and stable FM stereo separation of more than 40 dB, IC equipped FM-IF section features a built-in quadrature detector for excellent linearity and minimal distortion over an exceptionally wide frequency range and two-stage ceramic filter for better selectivity.

 

Elegant and Easy-to-Operate Design

The new lighting structure enables clear reading of linear dial scale and AM/FM tuning meter, and the enumerated bass, treble, balance and volume controls facilitate easy reference. Other features include a loudness switch for clearer low volume listening, a mode switch with FM muting circuit for quieter tuning, a tape monitor switch and push-button speaker switches for easier selection

 

Multiple Connections

Connections include Phono Jacks and two full speaker systems. Dubbing from a tape deck to a tape deck is possible using Aux and Tape Jacks. Tuning, preamplification and power amplification in one slim cabinet. Do them well with quality Akai receiver AA-1115.
