For Sale - Pair of ATC MK2 3 Way Active Amp Packs
Bass 200w@ 8ohm
Mid 100w@ 16ohm – can drive 8ohm no problem
HF 50w@ 8ohm
On board 3 way active 24db/octave crossovers with adjustable phase for LF, MF. Pots for adjusting channel drive levels. Gain reduction circuit and output for LED to indicate limiting.
Amp sections class A/B biased into class A. Each amp section is identical for LF, MF and HF. Supply voltages are different hence the output power differences.
Pots for LF boost and gain trim.
These are the pro versions of the MK2 Amp Pack as used in the majority of ATC active products. SCM50ASL, SCM100ASL, SCM150ASL etc. These packs came from a pair of SCM150ASL’s which I am now using with a pair of ATC discrete amp packs; hardly any difference between MK2 and discrete but one pair has to go hence the sale.
The levels are currently set for SCM150’s but these can easily be adjusted to suit different models. Domestic MK2 is the same except it doesn’t have the pots to adjust LF boost and gain. Built 06/2006 and working perfectly. Can demo to buyer.

Hi. I have the same 150s and was also looking to upgrade the amp-packs. Can I ask how you get hold of the discrete versions and how much were they? I believe you need to adapt the cabinets as well don't you as the transformers are on a separate panel?
