The 120 watt per channel R12 receiver from SAE TWO
It shares all the basic performance and design characteristics of the R18 minus a few of the added conveniences. Like the R18 it offers wide and narrow IF band selection. (Wide for normal reception and narrow for weak signals or unusual reception conditions)
Also like the R18, the R12 features optional infrared remote control capability for convenient turn-on, volume, balance and tuning.
You're provided state-of the-art digital readout, flourescent bar graph displays and much more:
Synthesized Touch Tuning.
Quartz lock.
External processor Input.
Tape EQ.
Single Strata Voltage Amplifier.
Full Complementary Outputs.
Infrared remote Control (Optional).
Parametric EQ.
Low Noise Phono IC's.
Moving Coil Input.
Relay Speaker Protection.
