As such I conclude for now that the phase knob is best left at zero and that I’m better off using the delay function in the receiver.Īt least I can not imagine why I would need phase shift when delay is possible in my setup. true time delay elements, and an inductance tuning technique is introduced which enhances the delay tunability of a synthesized transmission line while keeping its characteristic impedance con-stant. My best guess is that it is a phase shift circuit as it is clearly marked with settings for different degrees. I guess it is possible to execute both time shift and phase shift in the digital domain (thanks amirm) but without measuring the output I can’t know for sure. By the look of the input circuit it looks like some sort of imbedded DSP. is transmitted phase-shifted by 22 (i.e., slightly delayed) than from the lower radiator. I am not able to tell if the sub is “digital” or analog with confidence, but I opened it up and looking at the plate amp, my guess is that it is in fact digital. So if two radiators emit a signal in the same phase shift. This is readily available in the receiver.
The better solution seems to be a true time shift to align the phase of the sub and speakers. This might or might not be audible according to various posts found elsewhere, but is IMO best avoided if possible. Read more about how how we test products and services and how we make our recommendations.So from what I can gather from all of your posts are that phase shift is definitely not the same as a time delay, and that a phase shift circuit will introduce phase shifts into the audio signal itself. If you've already got the basics covered, then a more out there delay could spark some needed inspiration in your rig. They tend to be relatively niche, and it's a deep rabbit hole to venture down, but here we're thinking about pedals like the Montreal Assembly Count to Five, the Catalinbread CSIDMAN, the Red Panda Particle and others. Some, like the Boss DD-3, DD-5 and DD-6, deliver a distinctive tone of their own that sits somewhere between clinical and the darker, grungier tone of an analog delay.ĭigital emulations of delays have become commonplace with modern signal processing, and it's not unusual to see larger delay units emulating not only classic analog delays, but also tape echoes and other types of delay.įinally, there exists a somewhat hazier group of digital delays that aren't trying to emulate other sounds, but instead do something radically new. Depending on who you ask, you might hear them described as brighter or even clinical. If you turn up the feedback, you'll find that these can be easily coerced into infinite feedback and auto-oscillation.ĭigital delays are generally more pristine in timbre. (Image credit: Electro-Harmonix) Analog vs Digital: which one do I want?Īnalog delay pedals work by using a so-called Bucket Brigade chip, a capacitor array that gives them a distinctively dark sound that's increasingly lo-fi when you apply longer delay settings. That said, the Electro-Harmonix Memory Boy (opens in new tab) and Boss DM-2W (opens in new tab) are both worth considering if your budget can stretch to them. It's simple, sounds good, and even blends well with other delays and reverbs in case you later add more FX to your pedalboard, or indeed if you are looking to add a delay pedal to your current board. If you want a no-frills analog delay pedal that doesn't cost the earth, the TC Electronic Echobrain (opens in new tab) is a good place to start. If you'd rather get to the products, then keep scrolling. If you'd like to read more about the best delay pedals, we've included some expert buying advice at the end of this guide. If you're unsure where to start, then don't worry - we've rounded-up some of the best options in this guide for you to check out. Modern digital delays go far beyond their ancestors, both in sound and functionality. In phasor form, this is represented by the + j or -j in the inductive and capacitive reactance, respectively. It's said that a capacitor causes a 90 lag of voltage behind current, while an inductor causes a 90 lag of current behind voltage. The first echo effects used tape loops to replay the guitar signal, before bucket-brigade analogue delay pedals took over, due to greater reliability and lower cost. In this article, 'phase shift' will refer to the difference in phase between the output and the input. Let’s put it another way players from The Edge, to Tom Morello, to Matt Bellamy, and Johnny Greenwood would not have been able to create the music they did without delay effects.
