Hi Fyette, I am considering purchasing your PS-100 and had a couple quick questions:
Can I use it as an Impedence Matcher like the Weber Z-Matcher? I would like to run Fender combos (i.e., Super Reverb and Bassman) whose outputs are rated at 2 ohms into the PS-100, but then out of the PS-100 into various speaker cabinets whose impedences are at 4, 8 and 16 ohms for tonal options, is there a way to do this on the PS-100?
For clarification, the “2/4 ohm” designation on the back of the PS-100 really means 4 ohms, but is safe for an amp rated with a 2 ohm output (it will not damage the amp’s output transformer), correct?
Can I run 2 different amps at the same time into each of the 2 channels in the PS-100 where the amps have different output ohmages?
Yes, you can use it to impedance match dissimilar impedance amps and cabs. However, only when in OPERATE. When in BYPASS, the PS-100 is true bypass so your amp is directly connected to your cab. Obviously this also bypasses the impedance matching feature. This is probably not an issue because 99% you will likely play in OPERATE mode.
2/
The numerical ratings for amplifiers (2, 4, 8 and 16 ohms) are typically stated as “nominal”, which means average under typical operating conditions. That nominal figure is also frequency dependent (different for low vs. mid and high frequencies). The DCR (DC resistance), on the other hand, is not frequency dependent but a fixed value.
In short, the DCR of the 2/4 ohm setting on the PS is about midway between a 2 and 4 ohm impedance-rated speaker and therefore more than safe to use.
PS-100 has been tested with 2 Ohm vintage amps.
3/ Nope! It only has one AMP IN jack, this must be connected to only one amp.
