Convert 10dbU to 4dbV with attenuation

Hiya,

I have two devices:

One professional DAC converter with a output impedance of 51 ohms, 4dbU output which can be balanced TRS or unbalanced TS jacks, whichever is easiest for this.

A consumer-grade amplifier which is 10dbV standard with 20k input impedance.

I want to build an attennuator to convert the levels and add 35-40dB attenuation as well, to the signal.

Been looking at a H-type attenuator, but not too sure on the resistors needed etc.

Any pointers for the best way to do this?

Thanks

I'd stick two 5K pots on the output, and adjust so the red light doesnt come on. But a 40dB att is 100:1 so a 100R to ground and a 10K from the DAC will be fine, and with 1% tolerance stuff, no problems
