Creek 4140 s2: speaker inputs

Hi forum, I've decided to get back into hi-fi after a break of 30 years, and have a query about a Creek 4140 s2 I have recently purchased.

The amp is currently in transit to me and was wondering if anyone could tell me what speaker cable connection it would likely have? I seem to read somewhere it maybe a bit 'special' (Deltron speaker connections perhaps?)...
