Booklet on two modular stereo systems from COLUMBIA: GL-K7D at ¥57,500 with four-band reception (FM, two shortwave bands, MW) and GL-K3 at ¥49,500 with FM and MW. Both are all-in-one: turntable, cassette deck, tuner, amplifier and 16 cm speakers. The inner spread is built around the slogan “5 sound sources at your choice” - Columbia treated shortwave as a full audio source on par with FM and cassette.
- モジュラーステレオ - integrated system: turntable, cassette deck, tuner, amplifier and speakers in a single body
- DCモーター - DC motor drives the platter more stably, without vibration or overheating
- ファイナルコンプリメンタリー回路 - symmetrical complementary transistor output stage in the amplifier (GL-K7D)
- マイクミキシング - built-in mixer: microphone blended in real time with playback
- ALC回路 - automatic recording level control for cassette, protection against overload
