Korg Pitchblack needs "at least 600 mA"??

[H3R3T1K]

I've recently got the tuner and have had noise problems. Now I've used a cheapo 500mA power supply and a daisy chain for the two effect pedals I used. I've ordered a a new higher quality supply which provides 5x120mA. But that's not nearly enough. The manual states that I need a power supply which provides at least 600mA. What do I do?

Wow that's obscenely much.
Either they calculated in some rather generous headroom, or this pedal draws a huge amount of power...

Good thing I read this. I was thinking of maybe putting one on my pedalboard, but don't feel like sacrificing 2 outputs of my Voodoo lab PP2 + current doubler cable.

By comparison: Polytune:

Current Draw: 45-50 mA (typical use)

... which is more standard.

Update:
After some research it seems this is a "worst case" requirement.
Should be no problem.

600 mA for a tuner? It doesn't make sense except if you use it to daisychain to other pedals and even then, the maximum ouput is 200mA.

 

[Downunderwonder]

Closer to 6mA than 600mA I bet.

 

[okcrum]

Given that it will run 5 hours (or more) on a 9v battery the current draw can't be higher than about 100 ma with everything (display, etc.) on.

 

[BioDriver]

Yeah I'm calling shenanigans. The 600 mA is probably too make sure there's enough power for the auxiliary out.

 

[H3R3T1K]

In the manual it says about the DC in that you need at least 600 mA and about the out which can power other pedals it says that these shouldn't use more than 200 mA. Funny people at Korg... Will try my new power supply and hope all stays quiet.

I run mine off an output on my SKB pedalboard that is 100mA max per output. I even use the daisy chain output to run my MXR compressor off it.

No issues

Yeah I'm calling shenanigans. The 600 mA is probably too make sure there's enough power for the auxiliary out.

I checked the specs, and it does indeed specify a 600mA or great PS, but also specs 30mA consumption, and a max of 200mA aux use - doesn't make sense to me, either...

I call typographic error. If anyone is interested I'll get my multimeter onto my PB tomorrow.

It is very common to specify a power supply that is much larger than what the device needs to operate.

One of the old-school “rules of thumb” is that a power supply operated at its ratings can produce 10% of AC ripple. A larger supply than needed will have less ripple, with less work load and will operate at a much cooler temperature. These common assumptions were accepted worse case standards when power supplies were nothing more than a step-down transformer, diode rectifier (AC to DC) and capacitor filters (DC storage and smoothing).

Ripple example: If a 10VDC supply was rated at 500mA it would have 10% of AC ripple or 1V of AC riding on top of the DC voltage with a 500mA draw. Now if the same supply had a 50mA draw you could expect the AC ripple to be no more than 0.1Vac.

Today we have very clean, regulated and cheap power supplies available… but someone will find an old DC adapter from the 70’s in a junk drawer and will try to use it.

Don't worry about it. It works fine from a 9V battery. Fat chance of getting this type of current from one. So, yeah it's a Furphy.

It'd need incandescent lights in it to require that amount of draw. Always had one on my pedal board, always neglected it's power requirements, never had an issue.

The Eventide pedal on the other hand - oh yes, they will reboot with not enough juice.

Pitchblack pedals - as long as they can light up they're fine. Good tuners too, so enjoy one

 

[arginator]

I run mine from a OneSpot, with four other pedals as well. Seems to work fine.

Agreed - it was probably supposed to be 60mA, if I were to guess...

[petergales]

The Owners Manual states the power consumption as 30mA, which seems about right. I have one and think it's a great tuner with a display that's far easier to see than the Boss TU2 I used to use.

 

[CAW]

Come now, no pedal board would be complete without a TU-1000 tuner, right?

I haven't had problems running my Pitchblack from a single VL Pedal Power 9v output. I formerly used a Roland PS-10 (?) and had no attendant issues. Perhaps you have a bad Pitchblack or there's some other cause for the noise?
