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

I have the components. I'm debating on buying balanced Audioquest Colorado cables and that's why i posted the question and can't find the answer on the voltage.

The line level should be fine, my concern is the output voltage from the dac. trying to get answer before purchasing cables.

Have you ever opened it and changed the balanced attenuation jumpers? If they are set to factory -20 you're fine if not set them to -20.

Benchmark is quite responsive to customers. You might try emailing their support department.

The manual shows the voltage but it’s in dBu. As long as the balanced attenuation jumpers are set to -20 or -30 the voltage stays below 10dBu or 2.5v.
.775v = 0dBu
2.5v = 10dBu
