PS-100 and ZMACS with bass amp and cabinet

Stage & Studio Power Station PS-100

I am running my PS-100 in the loop of my ZMACS. I have two ZMACS units linked for the max 7 amp 4 cabinet setup. I’m trying to choose what amps to incorporate without breaking anything in the rig.

I am looking to add a reissue Ampeg V4-B and an Ampeg 810 cabinet into my Fryette setup. The amp is 100 watts. The cabinet is 400 or 800 watt rms depending on dual or mono mode.

Is there any issue using such an amp with the Power Station or ZMACS?

If the the amp is an issue, anything wrong with using the cabinet through the ZMACS with different amps or without the PS-100?

I saw some posts about using the power station as a bass power amp or with higher rates amps and the issue with lower frequencies but wanted to be safe rather than sorry.

Thanks!

Hi @conrad213 and welcome to the forum!

I can’t see any problems with your setup at all.

ZMACS was developed using Fryette Deliverance II+ which is 120W, it can easily handle the 100W from your Ampegs.

As for the speakers, two things are important:

  1. The impedance is matched
  2. The power handling is equal to or greater than the amp’s output power.

You are fine on both fronts.

Hope that answers your question.

Hello and thank you!

Perfect. I had seen some other posts regarding bass setups, but mine setup seemed a bit different so I wanted to make sure. Great to hear that I am good to use all my equipment together!

For the speakers, the plan is to run everything at 8ohms to match my PS-100 and the majority of my other amps and cabinets, so should be all good on that front then.

Thank you so much for your help!

That should be fine.

Do you have a 16 Ohm tap on your amps? I’m just thinking that as you are using a bass guitar, this would reduce the current dumped into the reactive load. It’s a minor point really.

Only some of my guitar amps have a 16 ohm option. The other guitar amps max out at 8 ohms. The Ampeg bass amp has only 2, 4, and 8 ohm options. I only plan on using the bass with Ampeg.

I also only use one guitar cabinet rated at 16 ohms. The rest are 8 ohms. Currently I use the 8ohm tap from all of my guitar amps and have the PS-100 in the ZMACS loop set at 8ohms for both amp and speaker.

Yeah that’s fine, 8 Ohm will work.

Great. Thank you so much for confirming and for all your help. Really appreciate it!

Sorry one last thing - I looked over the 810 cab manual and to run all 8 speakers would be at 4 ohms.

Is there any issue running the Ampeg bass amp and bass cab both at 4 ohms? Would I have to make any adjustments to the PS-100 (currently set at 8 ohms both amp and cabinet) or ZMACS?
