If you put four 16 ohm speakers in parallel on your amp you should set it to 4 ohm. You calculate that as 16 ohm/4 = 4 ohms because they are in parallel.

When you put speakers in series then you add the impedance of each. You can ONLY series speakers if they are identical AND in identical cabinets.

How do I activate speakers on Clavinova CVP 601 piano after having disconnected the head phones

It is likely the contacts on the headphone jack are sticking. If you're lucky, spraying some contact cleaner into the input will loosen it. Be careful not to get the spray onto the rest of the cabinet o the keys. If that doesn't work, you will need to take the unit apart so you cab get to the part to clean it.

How do you change from 4 to 8 ohm output on a phonic 1860 mixer

Stereo and bridged mode selects automatically. Stereo mode gives 4-16 ohms per side. Bridged mode is only from 8-16 ohms. This impedance match is created by the combination of speakers you use. If you link any speakers, the wiring is usually going to be in parallel because of the sockets wiring in the cabs. Any time you link 2 speakers in parallel, it cuts the impedance in half. Remember that in bridged mode, do not link 2 8 ohm sets together because this will create a 4 ohm circuit which it will not allow. This can only be done in stereo mode. It is ok to use speaker combinations of higher impedance, but never go lower as it would cause damage to the power amp.

Can i connect 2 (2x12) cabs rated @ 4ohms each to my avt50 head?

No, the ATV50 head is rated for 4 ohms total. Using both 4 ohm cabinets at once will fry your amp. Your only option would be to rewire your cabs internally to 16 ohms each by connecting the speakers in parallel, but that would cut your amp's power in half.

I Have A Peavey Valveking head and cab. I was wondering what inputs for the OHMS to put it on if i were to be playing in a band. 4, 8, or 16? and what input do i plug the speaker cable into on the cab, the...

The answer all depends on the impedance of your speaker(s). A single speaker can be plugged into either jack. Set the switch to the impedance of your speaker. If you use two speakers, set the switch to one half of the impedance of the lowest impedance speaker. Very few speakers are 16 ohm types. Most are 8 ohms and some are 4 ohms. You could plug an 8 ohm into each of the jacks and set the switch to 4 ohms for example.

I am not sure how you are measuring the power output to verify it is less than 200 watts. With a true RMS voltmeter you should see 28.28 volts RMS across a net speaker load of 4 ohms. If you use only one 8 ohm speaker, you will get 120 watts. If you are getting the 28 volts there is nothing wrong with the amp. You MAY have blown the speakers OR not generating much bass due to processing in an EQ. I assume you are using at least 15 inch speakers if you want to feel bass. Look up your speakers specs... you will need speakers capable of 32 Hz to feel much. With this amp your speakers should have aa total rating not less than 400 to 600 peak watts or around 300 watts RMS continuous power rating. Using a lot of high end EQ will keep the amp busy at the high end and reduce the power available at the bass end.

I have a Gallien Krueger Backline 600 head rigged to a GK Blackloine 410 BLX-II cab. There is a crackle sound emitting from all the speakers, so I'm guessing there is something wrong with the head. Have...

i) If the crackle is there with all input signal cables removed, then likely to be the head.

ii) Does the crackle vary noisily with control settings? If so, move noisy control to & fro about 10 times to wipe any dirt from internals (temporary solution).

iii) If ii) is not a problem, then tap head casing to check whether a dry solder joint or poor internal connection is the cause. Was unit dropped?

iv) If none of the above, then suspect possible component breakdown.

I have theUB802 model and I'm getting buzzing feed back from speakers. Any suggestions

Check for ground loops. Please read my tip on here in regard to speaker polarity hazard on the A channel output.

Ground loops are common if you don't have everything powered by a singel receptacle. Also if you are using DI's make sure the Ground Lift is set to LIFT.

Start troubleshooting by disconnecting ALL inputs and one at a time re-connecting to find offending input.
