Does this amplifier have a warm-up time? My piece sometimes takes several minutes before I get a sound output. Is this normal? Or a defective piece?

No warm up time required. Plug it in, turn it on, and you're ready to go. I think that Pyle audio equipment is an excellent value. I've purchase four pieces of equipment over the last several years and have been very happy with everything that I've bought.

Not that I have noticed. I needed to boost pc audio output and the Pyle amp does that just fine.

This unit is solid state. No warm up time, Instant on. Don't understand the delay.

There is minimal delay between turning on unit and sound output - seconds at most. I've had no trouble with this unit since it's purchase in August.

My works right away. I just turn it on and I start using it. You may have a defective piece.

I have not noticed any time to warm up. I"m amazed at the high quality sound I get . I hope it has a long useful life. Some things like my Century Link Modem contains a chip that causes the modem to fail when server format is changed. I hope this is not a future trend in electronics. I have to pay $180 per year to replace modems which have been programmed by my ISP to fail.

It could be your input cable from your music source. Try a different cable first before declaring the unit defective.

Sorry, I only use the Pyramid for the phono preamp. I turn it on when I play music. One time, I forgot to turn it off. The next day, it was still ok. Please check with the manufacturer.

Make sure you have the speaker's volume control at the medium level or lower, and keep the ON control to Auto. The other thing that may be wrong is the Polarity, make sure the plus side of the amp goes to the plus side of the speaker and likewise for the negative. .............. Hope this helps.

Does the popping still occur when you change the source to a channel that the pre-amp not plugged in? Have you tried switching the phono cable that the pre-amp connects to the amp with? I've not had this problem with mine, I'm using a a/c adapter to power mine.

It's also quite possible that the Volume Pot is not the correct one or is defective and could be why you have to turn it up so high. Was the sound ever distorted? Or was it clean? If you did overdrive the output you might have gotten distortion. But if the sound was clean but low in volume, then it might be the Volume control , preamp setting or output amp.

Check your inputs, good Mic, good cord & connections ect. Use a new or known good mic & cable. Then check speakers & wiring for damage or loose connections. Make sure speakers are connected correctly for their impedance (marked on speaker). User manual should help. If this amp has a radio tuner, make sure it's input (Aux In) is turned all the way down. Also turn down any inputs without a mic connected. If these steps don't fix it, then you may have a bad amp(s). There are some known quality problems with this brand.

To the person who said their amp is shutting off........please check your voltage regulator. I dealt with 2 pioneers and 1 JBL amp which did the same thing. The amps were good, but turned out to be my voltage regulator. Car stereo always worked fine, but amp would go into default.

No. I'm running a 700 mono block and it's not even turned up all the way. It's super loud. It's a great speaker. The box is nice. I want to run max but don't wanna buy a new amp.

Take it out of the box, tune it and it sounds great without any adjustments. I have amplifiers but like my electric/acoustic guitars I usually prefer it unplugged.

I wonder what your source component is and if possibly your converters are somehow not "playing nice" with the HiFiMan transducers.; I am into year 2 with mine and after 200 or so hours of break-in the mids and low end have opened up along with the soundstage but only positives have happened, nothing negative. (I am using an Oppo BDP-95 running via XLR to a Teac HA-501-B headphone amp. ALSO, it may be something is loose inside the cups that is resonating. I can honestly say other than not liking the way my cables attach, I can find very little to complain about regarding these cans. Good luck! Cheers! Marty G

Sounds like a wiring problem with your amp. Speakers are very simple to get working

It sounds like you must have a defective unit. I don't get a hum with either tubes or solid state amp. Sorry yours is making bad noises.

I think that you may have one of the switches on the back set to "auto". In this mode you can leave the amp powered on, and it will detect an input signal, and power up your output stages. If you change the switch to "normal" you must turn the amplifier on and off by pushing the power button. In "normal" mode, it should play soft passages, and fade outs as expected.

I had this amp for about a week. It was under powered (couldn't use it in a band setting) and was noisy. I returned it.

Check your speaker connections,and the speaker cords need to be the same length.mine takes 35-40 seconds before you can hear music.Jb

The popping you hear is the tube warming up; tubes usually take 10-15 seconds to warm up. This is inherent of tube amplifiers.
