Please tell me I'm not screwed!

I just ordered XLR cables for the Marantz preamp and amp, following exactly what it told me in the MM8807 manual (p. 4):




I had already mounted it in my rack. While connecting one of the last few connections, I noted this on the back panel, to my horror:



That's just about the exact opposite. The cables have already been ordered and shipped. Now what do I do?

Gary

Thanks for responding.

I sure hope you're right. But when I look at the preamp manual (p. 16), it says this about the AV8801:

This unit is equipped with BALANCED XLR IN terminals. Use these terminals if your device has an XLR terminal as an audio output terminal.
When using BALANCED XLR IN terminals, assign “XLR” for “Input Assign” – “ANALOG” (vpage 134). By default, these terminals are disabled.

Then it repeats the same information in the amp manual. But the preamp does not have XLR in, correct? Those are OUTS.

Gary

Thanks, fellows. It's clearer.

What really was confusing was when I turned to the preamp manual, which repeated the same configuration as the amp. But I guess they were trying to show what the PIN arrangement is coming into the MM8077, even though it says

{AV8801 BALANCED XLR IN terminal PIN arrangement}

and then repeats the same information on page 31 for the amplifier configuration.

That would make no misprints, just very confusing.

I'll sleep better tonight. Thanks all.

Okay, so I received my XLR cables today and ran the Audyssey XT32 calibration. It shows that my C, FHL, FWL, FWR, SR, SL, SBL, SBR are all out of phase, even though I triple checked the speaker connections, positive and negative. All of these are using the XLR connections.

For some reason, FHR (front height right) does not show put of phrase, even though that is using the XLR connection. (Fronts right and left are bi-amped and I'm using RCA unbalanced connections while I await the XLR cables.)

Since I had a week of waiting to receive the cables, I ran RCA unbalanced interconnects. No phrase problems using Audyssey calibration.

So I "am screwed" after all? Something I'm missing?

Gary

Yep. Pin 2 hot. If you look at the first post, the amp is in the first picture and preamp in the second.

I ordered through Blue Jeans Cable so I could get 3-foot cables. XLRs are not available locally, except in 25-foot lengths for microphone hookups.

The biamped speakers (RCA) don't show they are out of phase; neither does the right height speaker (XLR). But you may be right. Perhaps the fronts are throwing off the measurement since they are biamped and using RCA (unbalanced) connections.

I'm going to run through the speaker configuration again and see if the selections are all correct--RCA or XLR for each set. Thanks.

Gary

Not yet. When I hooked everything up, the Audyssey setup showed the speakers were out of phase. All except the bi-amped fronts were connected to the Amp via XLR. I returned the cables for retermination and ordered a y-cable xlr--straight pass through instead of "Euro wiring. "
