Another sound question
We've all heard about the non-line level input of the XLRs...but, there is the possibility that is wrong. Yesterday I spoke with a friend of mine who has regular contact with a Canon rep because the organization has ordered several XL2s. He brought up the audio issue to the rep, who checked on it. The rep claims that the camera detects automatically whether there is mic or line level coming in. If it's line level, ie., from a mixer, the camera will switch over automatically. That's what he said. I only have this second hand and don't know if it's true. I know my friend is a pro and reliable. Could be the rep is full of it, doesn't know, or it is true. I'm wondering if somebody with an XL2 and a mixer might check this out. Should be a simple thing to do...just hook up a line from the mixer to a camera XLR, flip on tone from the mixer and see what happens.

This has been fully tested and is not correct. The XLR inputs are MIC level only.

See thread for extensive info on this subject.

You don't have to tell Bill to see that other thread. He started that other thread.

Bill Pryor September 25th, 2004 08:44 AM

Yeah, i started it and I'm still in the dark about it. I don't recall seeing anything about anybody actually doing a test to see if maybe the camera does really take a line feed after all. I didn't think of it either till I got this second hand info from the Canon rep. I really would like to know if it's true or not. My natural inclination is to not believe anything any salesman says till I check it out for myself. When I first heard about no line level switches, I was incredulous, thinking it had to be a mistake. So it does make sense that the camera might take care of the issue internally and automatically. That would be very cool if it did. So far, the XL2 is very close to being a terriffic camera for the money.

Chris Hurd September 25th, 2004 12:04 PM

Agreed. I have serious doubts about the "automatic sensing" claim, but I'd really like somebody to try recording a mic-level source and then a line-level source through those XLR jacks and tell us what really happens.

Greg Milneck September 25th, 2004 02:43 PM

Sorry, I didnt realize that.
I tested the input....it is MIC level input, not LINE level. I thought I stated that clearly in the earlier thread, but I guess I didnt.

Besides, I have never seen a camera that auto switches between line/mic. It is always a physical switch....I dont see how it could auto detect and switch this.

Regardless, it is MIC LEVEL only!

Greg Milneck September 25th, 2004 02:45 PM

BTW Bill,
The camera will take a LINE input, but only thru the (unbalanced) RCA connector.

Bill Pryor September 25th, 2004 02:59 PM

Yeah, I'm aware of the RCA line inputs. Weird to have it on unbalanced but not where you need it. I keep hoping the rep was right.

Robin Davies-Rollinson September 25th, 2004 03:39 PM

Since there is a switch in the XLR inputs from MIC to ATTN, wouldn't this drop the input level down to LINE?


Greg Milneck September 25th, 2004 04:59 PM

No, the XLR input is MIC LEVEL ONLY!
The ATT switch is a simple mic attenuator and doesnt even come close to allowing a Line level input.

Let this rest....the XLR input can NOT accept a LINE level without external help.

I own the XL2 and have personally tested this.

I know we are trying to figure out if we have a "line in" and according to the manual (which seems to have some omissions and errors) there is no mention of one. There is mention of a "line out" which I have a question about.

In the audio setup mmenu, there is a setting "AUD. M. SET". And the choices are, "NORMAL" or "LINE OUT".

Page 28 of the manual mentions this setting and references to page 53 for an explanation. However, ther is no mention on page 53 or anywhere else for that matter.

This being the 2nd un/poorly documented item in the manual, no doubt there are more.

Any insight on what this setting is about would be helpful.


Chris Hurd September 26th, 2004 09:17 AM


Look at the very bottom of page 53, the last paragraph. This setting simply selects whether or not you want to hear the audio delay when you're monitoring with external gear (audio is always synced to video on the DV cassette).

Evan Fisher September 26th, 2004 10:29 AM

Oops, User error.

Thanks Chris.

Rick Step September 27th, 2004 11:03 AM

Don't some mixers allow you to switch between line and mic...if you have one such mixer, this wouldn't be an issue. Is that correct?

Lauri Kettunen September 27th, 2004 12:13 PM

Rick, mixers may have a switch between line and mic on input but not on output.
