Commentary
Decoder amplifier with built-in regular / SQ matrix circuit.
Using the Tape Rec/Mon jack of the 2-channel amplifier, you can easily convert to four channels regardless of whether it is a separate type or a component type.
In addition to four channels of regular / SQ matrix, four channels of discrete tape are available, and CD-4 playback is also possible by adding a demodulator.
In addition to independent tape recording and re-terminal for 2 channels and 4 channels, a spare input terminal for 4 channels is provided.
The four level meters and four level controls make it easier and more accurate to adjust the level of each channel.
In addition, since the master volume is mounted, once you decide the level, you can control it at once.
Equipped with rear dedicated tone control, you can control it freely.
