Hello,

can anybody help with information of the Balanced Input Stage of this amplifier. Like to convert an older model from SE to balanced input.

In the VTL book is only the SE version.

Thank you,

Reinhard

Hi

I found a solution with other VTL amps using the trafo Sowter 3575, it is a 1:1+1 10Kohm.
You can connect in balance mode the primary and in unbal the secondary to the amp input.
Normally I put it inside the amp close to Rca input; normally a old VTL amps have a hole for XLR .

bye
