Know before you buy
Before the RIAA standard became universal in the mid-1950s, record labels used various equalization curves for their pressings. The 100 combinations allow you to precisely match the EQ settings to the specific era and label of your vintage records, ensuring the frequency response is accurate to the original recording.
Yes, the EQ-100 supports both MM and MC cartridges. It features dedicated input settings to accommodate the different gain and impedance requirements of each cartridge type.
The Bass Limiter is designed to manage low-frequency output for specific historical curves like DECCA and RIAA. It prevents excessive bass resonance, which helps maintain clarity and prevents distortion during playback of older monaural LPs and 78rpm discs.
The EQ-100 is designed with a pure, monaural signal path, making it ideal for dedicated mono playback systems. If you are looking to play stereo records, you would need two of these units or a dedicated stereo phono stage.
No, the EQ-100 does not feature a built-in subsonic filter. It is engineered for a direct, pure signal path to prioritize audio fidelity and accuracy over signal processing.
The front panel features two primary controls: one for Turnover and one for Roll-off. By consulting the documentation provided with your records or using the included guide, you can dial in the specific settings for your record's label, such as Columbia, NAB, or AES.
