I am so excited that the new stompboxes, such as the Harmony Singer2, will run on 9v instead of 12v! I am planning to put one on my pedalboard and run it off of my Voodoo Labs Pedal Power 2+, but just need to know how many mA it actually requires so as to know which power outlet to use on there (or if I need to double up for more mA etc...). Thanks!
I just recently purchased the Harmony Singer 2 and was wickedly impressed, but after taking it out to its first gig, it went totally haywire.....needless to say my impression dropped to disappointment.... Then I found (and did) the firmware update. I really hope this works. (it seems to work fine when I'm practicing at home).... Anyway, We have another gig in a couple of weeks, and my faith in this unit is very dim, I sure hope the firmware update does the trick.... I absolutely love this thing, its awesome.
Now to get to my question... I noticed, when I turn the tone button ON, the voice level drops to at least 1/4 less than with the tone button OFF. Is that normal ?
Yes that is normal. There is come subtractive eq'ing going on in the bottom end with the Tone button. How much depends on your microphone and voice, but it's not uncommon for Tone to slightly reduce the perceived level.
Our Keyboard/2-vocals/Harmony/Guitar busking rig uses a 12volt battery. It has become so reliable and simple we don't bring an extension cord or wall warts any more.
Rolls 4-channel mixer with phantom power, Casio 560 keys, Shure Beta 54 headworn mics, HH2, MM2 (2nd singer), Ipad backing tracks. Portable, really cool and simple.
Some of the items in our rig are 9v others 12v.
We use small voltage converters, solder them to the leads for the 9v gear then enclose them in wide heat shrink tubing to protect them. They are crazy inexpensive ($2.00 each) and will provide up to 3,000ma. A local computer repair shop will build them for you if you need help. Here is an Amazon link:
You will need a DC volt meter to set the output voltage and drop it from 12v to 9v.
New battery technology led us to Lithium Ferrous Phosphate (LFP) batteries 6-years ago. They are even better now.
Ask for Kevin Zanjani - tell him Ed Koplin sent you. LFP's can be charged and discharged thousands of times and are 1/4 the weight of a lead (yuck) battery. They are the safest Lithium battery too. And LFP's do not drop lower and lower in voltage as they run down....they stay over 12v until they go dead. One last thing (sorry to geek out) once you charge them up they stay charged for YEARS. Literally. A 2lb (1kg) LFP will run our keyboard, small amp, MM2, HH2, two mics and two USBs for Ipads for 4-hours. We charged a spare 2-years ago and when we went to use it it was only on the charger for 3-minutes and went green.
ALSO some items in our rig are "Center pin +" others like TC-Helicon (VLT2, HS2, MM2) are "center pin -" To avoid plugging in the wrong polarity we buy polarity changers for the TC-Helicon products and LEAVE THE POLARITY CHANGERS PLUGGED INTO THE TC-DEVICE. That way we can run an industry standard "center pin +" and not think about where which cord gets plugged in, or what device is this way or that way. If there is a polarity changer in the device, leave it there...simple. $4 each. Could save your gear, if you are busking.
