One method is based on this DIYRE-article. It uses a Carnhill VTB9046 (2+2:1+1) Line Level transformer. The primaries are put in series and secondaries parallel (4:1). This results in a Source/Load impedance of 10KΩ/600Ω. Following the article, input ZΩ is 16K7 using a terminating resistor of 1K and output ZΩ is 15K.

A very similar but cheaper method uses a Monacor LTR-110 (1:1 / 2:1) Line Level transformer configured as 1:1 with a Source/Load impedance of 600Ω/600Ω. Input ZΩ is 680 to correctly load the transformer for a line level signal and output ZΩ is also 15K.

An alternative cheap method uses the Neutrik NTE 10/3 (1:3:10) configured as 1:10 with a Source/Load impedance of 200Ω/50KΩ. The line level signal is attenuated with an U-Pad at the input. The impedance is controlled at the primaries with the 300Ω shunt resistor.
