Safety functions

Stage & Studio ZMACS
1

Hello,

In the manual there is no reference to safety feature (for the amps). I was wondering:

  1. the non used amps are always seeing a load?
  2. what if I select a cab, there is a cable inserted in the ZMACS out of that cab but that cable is faulty will the device understand that something’s wrong and won’t enable that choice? Other switchers have these features. I was wondering if the ZMACS has them

Thanks!

Hello,

Welcome to the community!

1.) Yes. They are both muted at the input and are seeing a safe load on the output. Please note, however, that the load is purely a safety mechanism and cannot, of course, permanently dissipate excessive power.

2.) If no cable is plugged into a cab output, the amplifier is protected by the safety load mentioned above. We generally recommend the use of robust, high-quality cables in order to avoid such a fault condition from the outset. Imagine if you connect your amplifier directly to a cab, it won’t recognize an open connection either.

Best regards,
Julian

So it won’t be able to check open connections? If I plug a cable then he will just suppose there is a cab connected? That is unfortunate…taken from another switcher manual:

“A CABS button can only be selected with a speaker cabinet hooked up to the corresponding SPEAKER CABINETS jack. Thereby the XXX not only controls if a plug is connected to the SPEAKER CABINETS jack, but also the attached load for its impedance. A low impedance is interpreted as a speaker cabinet, a high impedance could be a non connected cable, a defective speaker cable or even a speaker in form of a ruptured speaker coil etc. In that case the XXX would refuse the selection and state an ‘n.c.’ in the display for ‘no connection’. This way the XXX prevents your amplifier from damage because of running without a load.”

It would be nice for the ZMACS to have these features…I SO want to buy the ZMACS for its feature and integration with the power station but this is an important point and needs to be addressed IMHO…hope the ZMACS can do it!
