Default Audiolab 8200CD impedance question??

I'm planning on having a cross-feed device designed to be used with the Audiolab 8200CD and cannot find out anywhere what the output impedance is from the balanced XLR outputs of this CD player. Any help with this is greatly appreciated.

John Westlake, are you out there??

Do you have circuit showing the output stages. I'm guessing its all opamp based, if so just look and see if there is a series resistor from the final opamp outputs to the sockets. If so, that's your impedance, if not, then its really low (as in fractions of an ohm)

Thanks for the reply. All I have to go by is the minimal information in the owners manual. There are no schematics.

OK, I've just dug a circuit up and its not what I was expecting tbh. Its discrete output, but very low impedance <5 ohm.
