PS-2A why 2 switches if they have to match all the time

in what kind of scenario would the impedance settings be different from one another. In other words why would you change an amp impedance of 8 ohms to a speaker impedance of 16

Hi Anth32,

If I’m understanding the question correctly, you’re asking why there are two separate impedance selectors. There are a good amount of scenarios where there could be an impedance mismatch but the Power Station is different than most attenuators. It’s different because it has an amplifier built into it and requires its own impedance switch for it’s power section. Let’s say you have a vintage amplifier with a fixed impedance, say 2 Ohms. You have a 4x12 cabinet that is 16 Ohms. The Power Station gives you the ability to use those two units together safely. It also gives you the ability to bring that vintage amp to its sweet spot power amplifier-wise while keeping the level manageable.

Another reason is keeping an amp in an impedance selection that “it” likes. In other words, that we think it sounds good in while using a cab we like the sound of that may be in a totally different impedance. I hope that makes sense.

Thank You,

Terry

ok so if that was the case i would put the amp imp at 2/4 and the speaker imp at 16? Also, your talking about Head right not a combo

Hi Anth,

That is correct. 2/4 Ohms for the amplifier impedance and 16 Ohms for the cabinet. It could be a head or a combo. You may need to make a cable set for it, but we can do combos too!

Thank You,

Terry

Its import you do not use the BYPASS switch when there is a mismatch. Because the amp is directly connected to the speaker in bypass mode.

Hi Stephen,

Good catch! That is absolutely correct.

Thank You,

good to know, thanks you guys, Im just running this with old blackface combos.
