[Timo]

All the previous Viruses use domestic 'unbalanced' analog outputs (-10dB), whereas the TI uses the more professional 'balanced' analog outputs (+4dB).

I don't actually have a TI (I only have an Indigo) so am not sure what the new balanced connections are like (if they are software switchable between -10dB and +4dB, like many soundcards are for example).

To make the best connection between the Virus and mixer you'd need a TRS, balanced connection for each analog output of the Virus to the mixer.

TRS = Tip Ring Sleeve. It's just a fancy way of using a cable with three wires (like what you'd normally use for a stereo connection) to transmit a balanced signal that's less prone to picking up interference/noise/hum along the way.

TS = Tip Sleeve. These are standard two-wire cables (like what you'd normally use for a mono connection) to transmit an unbalanced signal.

Usually if you use an unbalanced (TS) connection/cable on a balanced input/output the volume difference will be marked. So long as cable runs are short, and you don't have excess interference, using unbalanced should be OK, the only difference is that you'll have to boost the signal on your mixer to account for the lower signal level.
