Pioneer SP-101R

Commentary

Synth-sized surround processor for surround effects.

Equipped with a surround mode selector that allows you to enjoy four different types of realism.
Studio mode is for the source of studio recording, so you can feel as if you are in the middle of a studio or in an orchestra box, in Theater you can feel as if you are in a movie theater or in a concert, and in Stadium you can feel as if you are in a sports or outdoor concert.
Simulated Stereo is intended for mono sources, so you can enjoy a wide range of sound and a feel of a hole in mono.

It has a built-in Super Base Synthesizer to produce a heavy bass sound.
We extract frequency components around 110 Hz, 90 Hz, 73 Hz, and 60 Hz from the program source, and create ultra-low frequencies corresponding to half of them to create heavy low frequencies.

It is equipped with a synthesizer level controller that can change the synthesizer level of the ultra-low added to the front and surround.
It is also equipped with a push-cut switch in order to make the music source feel unnatural when the ultra-low range comes out.

It comes with a wired remote control that can control the front and surround volume independently.

In addition to the black model, there was also a silver model.
