![]() I also just noticed that I can set parametric EQ on my SVS sub woofer to roll of low frequencies, wonder if that would offer similar solution. ![]() Still I am a bit perplexed can't find much information that someone would be using such DC filter for connecting modular to hi-fi receiver. Understood! So seems like this DC filter would be useful to insert between the modular and the receiver. Some of your modules may do digital signal generating or digital processing internally, but they are outputing an analog signal and your overall output from your Eurorack modular is also analog or you would not be able to hear it unless you first connected it to a dedicated Digital to Analog converter before sending it to the receiver. So the signal you are sending to it from your synth is also an analog signal, not digital. This topic is now archived and is closed to. Your Yamaha receiver is an analog receiver. The subsonic filter is a high pass filter that prevents non audible signals from getting amplified, this has two effects, reduced current draw/heating on the amp and in ported boxes better excirsion control below tuning, theres actually no reason to leave it off. DC-blocking filters are a type of high pass filter that remove DC offset and other extremely low signals that are below the audio range (below 20 Hz) because this is one of the major things that will damage a subwoofer (or any speaker, for that matter).Ģ. DC in an audio signal can be thought of as an infinitely low frequency, and you don't want DC offset in the audio signal that you send to the receiver (and them onward to your speakers and subwoofer). At least reading the manual I could not infer that it has a built-in high pass filter.ġ. It is pretty basic so I wouldn't expect there to be driver protection against very low frequencies - however surely any pro-grade sub woofer should have that? I have a domestic Yamaha sub-woofer on my hifi. I trashed the driver in my beloved Peavey KB300 combo when I inadvertently sent an LFO signal to it from my Minimoog.
