I never heard of Cirrus, but there is DACT, Goldpoint, Elma, Shallco, Noble, Penny and Giles, and etc, all of which make excellent two-channel balanced attenuators in your choice of impedance. (I am sure I left out a few other quality brand names.) Depends upon how much you want to spend. In addition to conventional resistor-based attenuators, like those mentioned, you can also think about attenuators based on light intensity and a photo-electric cell. (I guess that is what danager points out above; I personally would stick with resistors.) No reason to mess with an 8-channel device when you only need 2. If you don't already know much about attenuators, you might want to spend some time familiarizing yourself with the pluses and minuses of the various types, e.g., series, shunt, or ladder type, and e.g., stepped attenuators vs continuous types, etc.
Looking for a 2-channel high end volume control
I am working on a balanced design and I need a gain control with two channels. I currently am considering the Cirrus Logic CS3308/18. Details here: https://www.cirrus.com/products/cs3308-18/
However, unfortunately, the Cirrus is an 8-channel gain control and they apparently do not have a 2-channel version of this chip.
Is there a chip of comparable quality that can simultaneously perform gain control on two channels?

Optical resistor Haven't come across talk of LDR attenuators for a while... I could never work out what the attraction was. This one tracks about the same as a half decent pot (0.5dB ∆ L/R) but has 0.5%THD. I'd be interested to know what it is that makes them an attractive option... maybe people like the sound of the distortion? |
