Ampeg PF-50T using 2 cabs?

[scootsmason]

Is there a way to run the Ampeg PF-50T to 2 cabinets? I have the amp coming soon and am planning on using it with my Fender Rumble 1x15 cab with horn. Wondering about adding maybe a 1x12 or 2x10? Anyone know for sure if this can be done safely and how I would go about it? Thanks!

Yes, very easy: on the Ampeg PF-50T you can choose the impedence between 8 Ohms and 4 Ohms.
The Fender Rumble 1x15 cab is 8 Ohms.
Set the PF-50T to 8 Ohms if you use it with only one cab.
If you add another 8 Ohms cab (1x12 or 2x10), simply set the head to 4 Ohms.
Then you connect the amp to the first cab, and the first cab to the second.
Classic.

Itll run 4 or 8 ohms via a switch on the back. Its set-up with 1/4 output, so if your cabs are speak-on youll need an adapter. So you shouldnt have a problem as long as your total resistance value is correct, and the cabs can be daisy chained.

If youre adding a 2nd cab, just get another of what you have, as long as they are both 8 ohm.

As a PF50T owner, I found it sounds great with mid-size to large cabinets. I run it through an Aguilar DB412 (4 Ohm) or an Aguilar SL212 (8 Ohm) with great results. Ive never tried it through a single driver cab, but I feel most folks dig this amp through any cab.

Thanks guys.
OK so in either of the two cabs pictured, I just go in with one and out to the second cab? When they say input does it mean one can function as input and one as output or passthrough? And set the amp to 4 ohms, correct? (FYI I wouldn't use two 1x15 cabs together. I already have the Rumble 115 and am considering the PF-115HE to use the amp as a fliptop, then adding a separate 1x12 or 2x10 8 ohm cab.) Just making sure as I don't want to blow anything up!

Correct

How do you Daisy chain these two HE cabs if both jacks on the back of these cabs are inputs? Do you need a cable that splits the signal?

This from the back of a 410HE. The jacks are labeled Inputs...but they are all just connected in parallel. This means you can use any jack for an Input and any other jack as a Thru to a second cab.

What you cannot do is use two jacks at the same time as inputs. I.E. do not connect two amps.

No. One is an input, the other is "pass throught".
The label "Full range inputs" on the Ampeg cab *IS* misleading.

Thanks! I assumed that! But I’ve been playing through combos since I picked bass back up last year, after a twenty year hiatus. I got the PF115he but am thinking about adding a PF210he
