Hello,
I just received my new ZMACS and was looking to confirm function of the impedance matching function on the ZMACS with the PS-100 in the loop.
Current set up:
- AMP 1 (16ohm)
- AMP 2 (16 ohm)
- AMP 3 (4 ohm)
- AMP 4 (8 ohm)
- PS-100 (set speaker and amp to 8 ohm)
- CAB 1 (16 ohm)
- CAB 4 (8 ohm)
When turning on AMP 1 with CAB 1, both show 16 ohm, passes sound
When turning on AMP 1 with CAB 4, both show 16 ohm, passes sound. When I turn CAB 4 to the 8ohm setting, I do not pass signal through to the speaker, even though it is an 8 ohm cab. This works the same with all amps, where signal passes with matching impedance displayed, but will not pass signal if impedance not matching.
Example: To pass signal it looks like my AMP 3 and CAB 1 are both at 4 ohm, though the CAB 1 is 16 ohm. If I switch to CAB 4, it will only pass signal when set to matching 4 ohm (on 8 ohm cab).
May I confirm that this is intentional/functioning as designed? I was not sure that I am getting the impedance matching function protection.
Thank you,
David
