Title: MP-2 Phantom Power?
Post by: arawak420 on September 19, 2004, 11:36:13 AM
i just got me mp2 in the mail from (deadband) and about to go out to a reggae festival today. i check my sonic mics, and they do phantom power up.

my ? is. i know phantom power uses the battery faster. i used my PA-6 batt box, and switched the mp-2 to phantom and it sounded the same with the batt box as it did without the batt box on 48v phantom mode.

will my mp-2 battery last longer if i use the batt box and switch it onto 48v phantom, or will it still drain the battery at the same rate as if i didnt have the batt box in between the mics and amp?

basically does phantom power drain at the same rate regardless of using your own mic power supply?

i think the sound sounds a lot fuller without the the unit running on phantom, it tends to sound scrathcy when db is gained in phantom. maybe it's just I.

sorry if post seem to coincide with each other, having fun with these tech toys the most high minds give.

Jah Bless the Tech Taper Junkies.<----- that sounds like a cult  ;D.  i have become one now

so you are running phantom power into your battery box? that cant be good

shhhh!  ;)

but yeah, I wouldn't use both phantom and battery box power...unless you like fireworks...

thats what i was thinking, that could cause some damage to your battery box

just how are you plugging your battery box into the mp-2?

i think i read somewhere he posted that he made a dual xlr > 1/8 cable to do that. but can you really send phantom through xlrs to a 1/8" plug?

nope!

so how is this guy applying phantom in the first place?

he wasnt, because the phantom wouldnt go through the dual xlr > 1/8" mini cable

se he was running the batt box and the phantom, but the phantom wouldnt work like that, so basically just running the batt box

just run the mp2 with phantom power.  if you have fresh batts you arent gonna kill them, not to mention your mics will have more dynamic range with phantom power as opposed to the bb.

oh and your sig looks like homer simpson's first website :-)

the sonic mics he has are miniatures, which won't take direct phantom.

ok then just run your batt box and turn off phantom on the mp2.  :-)

just how are you plugging your battery box into the mp-2?

still wanna know how this is being done...does the battery box have xlr outs? that would be news to me.

I thought most bat boxes had 1/8" stereo out. where do you plug a 1/8" into the mp2...into the tape return?  ???

you could add gain with the mp2 w/o phantom. i'm pretty sure you could.

if you go tape return does it add gain?

"he wasnt, because the phantom wouldnt go through the dual xlr > 1/8" mini cable" actually it does run on phantom power i dont like the phantom though cause it takes away from the fullness of the recording. there isn't any bass in the phantom design.

i pluged my mics directly into the female 1/8" mini> dual xlr and ran phantom.
i'll use my batt box from now on. yes the Sonic DSM-6s do and can run on phantom.

i ran phantom during one set, and the batteries drianed 1 hour 40 minutes. i was able to get the whole set, but it's not listenable or tradeable lots of distortion,static and hiss.

if you have mp-2 and can power the mics with their own power supply i suggest one does so for a nice full, warm recording.

phantom offers no bass what so ever. im a STRICTLY ROOTS MON taper. so i need the actuall bass not lots of high like one gets with phantom power. plus it ran my batteries dead, and gave me a shitty recording. turn phantom off= warm bass, and fullness

one more thing the level LIGHTS on the mp-2 do not actually turn all the way off. i noticed this when the evening sets came around. all the way off and you could still see the levels banging.

good LUCK, one love, and keep taping.

JAH BLESS THE TAPERS.

phantom has nothing to do with bass.  the problem you are describing is mics not getting the correct amount of power...which is very likely because you were trying to power mics wired for batt box power with a full 48V.  distortion and hiss are the results.

>>i pluged my mics directly into the female 1/8" mini> dual xlr and ran phantom.

i would strongly advise you switch off phantom on your mp2, because you're shorting pin 3 in the 1/8" mini.  

hence, you're not providing phantom power to the mics.

which is concurrent with why your tape sounds like shit...they are underpowered

I'm sorry for being an asshole, but you are now banned from talking about things you know nothing about.  Not to be arrogant either, but even I wouldn't make such inferences, especially when 5 people have told you "phantom doesn't work with 1/8" connectors," and "don't use phantom with a battery box."

my batt box does have a male 1/8" mini plug out. plug my mics into the batt box, and the male 1/8" off the batt box into the female 1/8">dual xlr.  i made the female 1/8"->dual xlr.

"phantom has nothing to do with bass.  the problem you are describing is mics not getting the correct amount of power...which is very likely because you were trying to power mics wired for batt box power with a full 48V.  distortion and hiss are the results."

i did have the filter set on 80hz w/ the phantom running (cut the bass more than i wanted). i got a couple good sets, but one set that ran 1 hour 40 minutes sounded like static,distortion, and hiss cause the batteries started dieing. mics run on phantom fine. it just drains the hell out of my machine, and when it drains the machine the recording is gawd awful.

i have the fucking machine right here in my face JAYGO. yes it does run on phantom w/ my 1/8" female mini to dual xlrs. makes nice recordings until the batteries start to take a dive. so don't try to tell me something when i have the machine and have been through several sets of recordings with it.

im shorting pin 3? how is this? pin 1 is grounded, and pins 2 is left and pin 3 is right or vice versa for 2 and 3. i don't notice anything shorting out. 1 of the 3 recordings i got came out like shit, cause the batteries didnt hold out.

supa crispy  I MEAN CRISPY TO. SO NICE recordings with the phantom,but man when those batteries get low its all over but the crying. i can send you guys copies of the Morgan Heritage set and the Junior Reid, plus you can get a chance to hear how sweet this stealth system really is.

Im gonna run the batt box from now on to save battery life and get a warmer, fuller sound. trial by error.
