Sony STR-7015 receiver

FM Stereo - FM/AM receiver

Features:

True complimentary direct coupled power output stage with differential dual power supply

FM IF stage with IC and solid-state filter

Triple tuned soild- state AM IF stage

 

Budget minded hi-fi enthusiasts will find the STR-7015 well within their reach and well up to hi-fi standards. Power output is moderate but adequate to drive a fairly efficient speaker. It doesn't take much to really appreciate the STR-7015's circuitry and performance features. Another fine example of Sony's advanced engineering and component design expertise.

 

Tuning

Up in the front-end the STR-7015 features in the FM stage an IC and soild-state IF filter for high stability and smooth, clean listening. Phase locked Loop (PLL) circuitry in the FM stereo demodulator delivers high stereo sepaaration and low distortion performance. Triple-tuned soild-state AM IF stage offers high selectivity for great AM listening. An illuminated frequency linear FM dial scale and signal strength meter make tuning a snap. FM interstation muting quiets the annoying between station noises for noise-free tuning.

Preamplifier and Control ections

A front panel Mic input jack allows for voice mixing with any source, i.e., phono, tuner, etc. PA applications are also possibile in addition to voice mixing for recording. Loudness compensation offers precise bass response and overall tonal quality at low listening levels. An attractive gold anodized control panel includes a headphone jack, mode switch, bass and treble controls and a tape monitor.

Power Amplifier Section

The STR-7015 features a direct coupled true complimentary power output stage that delivers 15 watts per channel, minimum RMS at 8 ohms from 40 Hz to 20 kHz with no more than 0,8% Total Harmonic Distortion. Though the power output is modest, the performance is outstanding. For operation of main and remote speaker, the STR-7015 features two pairs of speaker outputs in addition to a speaker selector switch.
