The following is a partial quote from Audio Heritage (website) 【BOSE 1706Ⅱ】 A power amplifier developed for use in professional settings such as recording studios and stage sides. Aluminum die-cast is used for the entire body case, which effectively cools the heat while increasing the rigidity of the body, suppressing vibrations and resonances that adversely affect the sound. The 1706II is equipped with Bose's patented PAP (Psycho Acoustically Processed) circuit. This circuit was developed to address the characteristic that the human ear has difficulty hearing sounds in certain frequency bands as the volume decreases, and it automatically controls the frequency balance to make the sound sound natural at any volume level. It is equipped with three input terminals, allowing various sources to be connected. It has a volume and selector on the front panel. Equipped with a Rec output terminal that directly outputs the input signal. #jupicaスピーカー
