Newbie, need advice.

I have a old school Bench mark DAC1.I recently bought a Luxman CL-38uC Pre Amp and it says be aware that the maximum input level at the balance input is 2.5 V and therefore sound signals may be distorted if a device with larger output level is connected. I look up the spec sheet on the Benchmark Dac 1 and it did not see the spec for the output voltage, unless i misread it. Can anyone pitch in on this and let me know if i can use balance input cables from DAC to PRE-AMP?

Thank You 
Jorica
