Commentary
This is a power amplifier developed for professional use in recording studios and stage side.
The entire body case is made of aluminum die-cast and is designed to be used as a heat sink.
This improves the rigidity of the body while effectively cooling the heat associated with high output, and suppresses vibration and resonance that adversely affect sound.
The 1705 II is equipped with a dedicated active equalizer circuit for use with the 101 Series to achieve the best matching frequency balance for the 101 Series.
You can turn the equalizer circuit ON/OFF with the switch on the back.
Equipped with an independent sliding volume on the left and right.
The Rec output terminal that directly outputs the input signal is mounted.
It can be layered with the Speaker System 101 Series or installed on the microphone stand.
