Topic: Marantz 671 in the field...

[sygdwm]

My first two field experiences with the 671 were coming digitally out of a Lunatec V3.  Since I had to return the loaner V3, the last two shows have been running line out of a Lunatec V2.  I had read some comments from other users about brickwalling on the analog inputs and I am happy to report there were no signs of that on my recordings...... 

So far I'm really liking the 671!!!!!!

You shouldn't have troubles brickwalling the unit if you're going v2 > line in, it's when you're going mic > mic in you'll have the problems without the mod.  You have 2 analog inputs, mic and line, I'd use line in if you're using an external preamp.

so when using a m148, should xlr>rca sound better than xlr>xlr? does that make sense?

Yes, it makes sense. 

the XLR inputs are the microphone pre inputs, you'd be passing through the 671's noisy stock preamp.  You have a m148, one heck of a preamp, squeaky clean too, you'd be doing it an injustice if you're passing through the 671's stock preamp. 

The big UNLESS you're not able to get decent levels through the Line In (RCA in) on the 671, depends on your mics output since the brick adds a non-adjustable +20db of gain.

Go line in if you can, screw the stock preamp, I'd avoid it if at all possible, ESP when running a preamp as nice as the m148.

great info. +t. fwiw, doug never mentioned a difference. he knew there would be a brick involved and convinced us to skip the mods.

Look at it this way...

mics > m148(preamp) > 671mic in 671preamp > 671 a/d > cf

mics > m148 > line > a/d > cf

The weakest link would be the 671's stock preamp, stock is somewhat noisy, hence the Oade mod (along with other reasons).  Even if it's modded, I'd still run m148 > line in (levels permitting).

Just the parts alone in the 148 cost about the same price as a pmd670...  If only Doug was designing the preamp stage for tascam or marantz...

If you bought it from Doug I'd highly suggest the preamp mod, it sounds great, definitely worth every dollar.

Ok, walk with it...

To the post office...

Send it my way...

Dang... I didn't get to try it out last weekend. I was going to try SBD feed via RCA and 481> mic in, but the band got fired from the place I was going to try it in!  Looks like my first time in the field will be RatDog 12-02.

[sygdwm]

I was going to try SBD feed via RCA and 481> mic in

at the same time? it will matrix-on-the-fly?

I highly doubt it, as far as I could tell you could only select either the mic OR line inputs.  (spdif too)

[sygdwm]

thats what i figured. just curious.

No, mic in and line in for different sets. Not sure if you can do line in and mic in at the same time. I assume not...

I run 2500 mh Powerex NiMH rechargeable batteries to power mine and I get 6+ hours on a set of batteries.  I do have an extra battery holder with another set of batteries in it that I can use for those marathon recording sessions..... but so far I haven't needed more than one set.  Sure is sweet to not carry an outboard battery system.

[sygdwm]

sweet. i am using the exact same batts. good to know. also, i just got done w/ my first ambient recording w/ this thing (besides record my stereo). i setup ROH (right of honda) in my garage 140>671 and recorded this wicked storm going over. mainly i was testing the auto-split feature, it is seamless. also i cant hear or see the overs in wavelab, which is good i think.
