Rare Teac casseiver or glorified all-in-one (recorder, amplifier and tuner in a box) with a twist : dbx !
The rest is nothing particular : auto-reverse for the cassette, eight FM presets for the Quartz PLL tuner, loudness switch, auxiliary input, timer rec/play, clock & alarm clock modes, a MIC input with line/mic mixing pot and a wired RC-95 remote control.
The amp section of the CR-R7 (CR-7 in Japan) can put out 2x 40W with an 8 Ohm load at 1Khz. Not much but quite enough to wake up with the soundtrack of Electric Dreams !
This wasn't really new salad in 1982 - but for the design : etched aluminium flat controls, a doubled-up front and top holding a gloriously slanted front. A real pity the good 1980s design ended in... 1984.
Like the A-1, the R7 was probably built by Cybernet, just before it got absorbed by Kyocera.
