192 I/O unbalanced input in a balanced setup

[AC Sound]

Greetings from an old-newbie!
A quick 192io input related question.
In my new brand 192 I/O I have a "+4 dBu Balanced input" scenario (+4 dBu DB-25
outputs connected to a balanced patch bay).

For about a week I do need to route an unbalanced signal -10 dB(V) (consumer device) into a pair of 192 balanced inputs.
I don't want (and I've no time) to change my setup or something.

I'd like to know: is it possible to connect (via balanced patch bay) and record an unbalanced signal into the 192 balanced inputs (I don't matter the +4/-10 signal volume issue)?

The "192 IO Guide" states: " You can connect -10 dB(V) signals to the -10 dB(V) inputs, but you will need to make sure that the negative terminals are not connected.", is it something?

Any help and advice will be very appreciate.
Ale

Gosh, you'd hate to have to do anything!!!

Buy a Matchbox. Every studio should have one anyway.

You're right, more than 11 years on DUC...

BTW, the Matchbox is a good idea but is there any other suggestion?

What is going to happen if I "simply" plug the unbalanced jack into the 192 balanced ones?
Are the 192 circuits going to "destroy" themselves?

no, they won't be destroyed
I don't remember the pinout of the -10dBv inputs but I think you could just move the DB25 to the -10 input connector then back when your done.

The pinout diagrams look pretty much the same but the 192 is in a not very accessible 19" rack and sadly I can't remove the interface for now.
Anyway moving the DB25 connector could solve the volume/impedance issue.

My concern is the possibility to connect a mono unbalanced signal to a balanced connector (both +4 and -10) with "the negative terminals connected".
I mean, could the 192 circuit be damaged in any way by a connection like this one?

[Craig F]

only if there is a massive amount of DC offset on the signal but then you would have bigger problems
