Title: V2 with M10
Post by: johnw on June 09, 2012, 01:57:25 PM
Has anyone used a V2 with an M10 before? I know the M10 can handle a hot signal, just wondering if anyone found settings that work well. I think I'm going to try 3 on the M10 and start at 20 with the trim at 0. This would be using the PFA and Nbox cable.

Dont forget that the "trim" on a v2 are actually attenuators, and arent true "trim" like the v3 has ;)

I usually run my V2 at 15 for louder bands, 20 for quieter, and the M10 at 4.

Thanks, I'll try that. There is no difference going rca out vs. xlr correct?

I can't recall, I want to say the XLR out is hotter. I run RCA out.

I do believe the XLR OUT is hotter ;) And remember what I said about the V2 "trim" John ;)

If it conforms to the normal standards.... it should be 14db hotter...

XLR are +4db    RCA are -10db

I'm not sure whether that is normal or not -- more of a marketing of pro level outs vs consumer level outs, not a reality of the design.  From a design perspective, unbalancing the outputs leads to a 6db drop in output, and the V2 complies to this -- the max output of the V2 on the XLRs is +27dbu, and the max output on the RCAs is +21dbu.

BTW, IIRC the M10 can take a >20dbu signal -- thought it was something like+24dbu.  At any rate, as long as you leave at least a little headroom on the V2, you should be fine.  I'd agree - set the M10 at 3 and work with the V2 to get your levels.

Thanks guys. I think I'll go RCA out to be safe.

I ran v-2's for years and always used the XLR outs to my AD2k or directly to my 744t or PDR 1000.   Typically I used the RCA outs for patching or running a 2nd deck .  I found the levels to be very stable and somewhat "forgiving". I've seen them run both ways with levels slamming red and just catching red on the peaks.  My mentors always said you were safe getting a consistent red on peaks but never staying in the red.

  I think you'd be save running either output option and personally I'd use the balanced outputs if I had the choice. I'm a huge v-2 fan for the record.

I ran the v2>m10 this way for quite some time and was always pleased wih the results.

The RCA outputs of the V2 are at consumer levels (-10 dBV) while the XLRs are at professional levels (+4 dBu), and the RCA outputs are unbalanced while the XLR outputs are balanced. So in both respects the RCA outputs would be a better match for a consumer recorder such as the Sony M10.

There's a rule of the universe that someone in every thread has to point out the following facts, so I guess it's my turn: The ratio between -10 dBV and +4 dBu is actually less than 14 dB, because the two reference levels are themselves about 2.2 dB apart; 0 dBV = 1 Volt while 0 dBu = 0.775 Volt. So +4 is only about 11.8 dB "hotter" than -10. That's assuming as always a no-load condition (but do you know anyone who ever operates equipment under no-load conditions? I don't).

On the third hand, whenever you unbalance some types of balanced output circuits you throw away half the signal voltage, while with others you don't--so beware of generalizations that go too far. Anyway, use the RCA outputs!
