Yes! A resistance would confirm.
hey Dan, so confirming that no, the ps-2a cannot be used as a through with switchable impedance as there is no resistance in the speaker out when the unit is completely off. however, I did find something that was a bit odd. I read that the 2/4 AMP IN tap actually reads 5.7 ohms. I understand that speaker loads are not 100% accurate but 5.7 would seem fairly out of range for a 2 ohm super reverb for example. Any thoughts?
Hi @gianc
OK, with the PS-2A turned off and with:
- Jack plug A connected to AMP IN
- Jack plug B connected to SPKR OUT
What do you measure between the tip of A and the tip of B? I was expecting this to be a thru path.
Hard to say without properly understanding the measurement you did. I remember it splitting the difference and being around 3 Ohms. Anyway, the DC resistance does not really matter too much because there is no DC on the speaker. What matters is the impedance at frequencies where the amp puts out energy.
Regards,
Dan
The measurement was taken with multimeter in resistance and negative side on bottom of tip and postive on top tip of speaker cable. the PS-2A completely off and with a speaker cable on the AMP IN with the 2/4 setting. Same as you would for silent recording. Anything im missing? It should read lower than 5.7 ohms
Is that in flat mode in all front panel switches? It does seem high, but I would just doubt the multimeter rather than the power station.
what does the multimeter read when you just touch the probes together? also, worthwhile to check the resistance of the the cable, tip-tip and sleeve-sleeve
