In addition to Viridian I'd turn it on when I play warped records.
Phono-pre: subsonic filter on or off ?
I currently have mine set to on. Does this mean I'm rolling off some bass and perhaps not getting the full bass slam I should ? What do most of you do that have phono pre's with subsonic filters...on or off ? Thank in advance.

INFRA -- SUB ULTRA -- SUPER are synonims as well as SUBSONIC or INFRASONIC. Technically you can say SUB RED but it's not common. Not only Carver produced the infrasonic dynamic filter. I've seen that in works of many different electronics designers adn Carver probably not the first implementing this circuit. |

It's clear that music is a complexed signal that has over and under tones. Rumble or subsonic waves of a large amplitude are not safe for the listener and can cause heart problem if not collapsing and should be voided. I've always thought that it's part of RIAA standards to have subsonic filters as a matter of fact since becides EMI causing rumble there are record or pressing imperfections that also can take part especially if played at the high volumes. |
2 beats per minute is the rough estimate of the heart beat. 4 beats per minute is 2x the heart beat that is blood circulating in/out... anything that is the closest magnitude of that is dangerous if reaches certain SPL magnitude levels and considered to be a weapon. 4hz, 6hz, 8... 12 could resonance with heartbeat. INSANE??? ANYONE WANTS TO AUDITION THIS MUSIC AND EXPERIENCE??? RAISE YOUR INSANE HAND... |
