New Aurorasound EQ -100 Phono

First information and specifications about the brand new Aurorasound EQ -100 adaptive multi-curve phono equalizer.   

This is a variable multi-curve phono equalizer amp that supports the cutting characteristics of all analog records from 78 rpm SP to 331⁄3 rpm monaural LP. The equalizer correction values ​​for low-frequency correction turnover and high-frequency correction roll-off can be adjusted completely independently as shown on the panel, and 100 types can be combined because there is no mutual interference. As typical cutting characteristics, there are four types of 78-rotation SP, pre-war and post-war (EU78 ~ 1945, AM78 ~ 1945, EU78 1945 ~, AM78 1945 ~) ​​after 1945 in the United States and Europe, respectively, and RIAA in LP. 

As a result, it is easy to preset to AES, DECCA, Columbia, NAB. In particular, DECCA, Columbia, and RIAA have individual Bass Limit characteristics to suppress the rise limit of the low frequency range and reproduce correctly.

From SP experts to monaural LP enthusiasts to those who want to listen to his pre-stereo sound, we have developed it as an easy-to-use analog record enthusiast.

For each variable value, each filter circuit was precisely calculated using a computer-based circuit simulator, the actual circuit was confirmed with an Audio Precision measuring instrument, and the capacitor and resistance were switched using a rotary switch. Each switch is designed so that the noise at the time of switching is almost inconspicuous so that it can be operated while listening to the record. In the conventional variable equalizer, he used the volume to change various curves, but he often used it, but in the volume type, it is about due to problems such as the contact quality of the rotating slider and the error between the rotation position and the resistance value. There is no choice but to display the panel. The EQ-100 eliminates all these concerns.

It also features an exterior design and wooden frame that matches vintage equipment, and a foldable tilt stand for easy viewing and operation of the front panel.

There will be new discoveries with this unit, such as musical expressions that have been buried or hidden until now, and the intentions of the performers.
