Markbass combo, cables to drive speaker from external head

Recommended Posts

Hello all

 

I have a CMD121P and a NY121P.

I’d like to be able to use an external head to drive both speakers in case the built in head (Combo II = LMIII) packs up.

 

So - suggestions welcome please on cabling.

 

I have a TC BQ500 and I’d like to drive both the 12” in the combo and the 12” in the extension cab in one go. I’m not worried about impedance matching or power - this question is purely about cabling

Here are the connectors:

BQ500 has Speakon out

NY121P has a pair of combined Speakon/ 1/4” jack sockets

CMD121P has a captive 1/4 lead connected to the internal speaker, which plugs into the output 1/4” socket on the internal head. (The internal head also has a Speakon out).

 

So I can run a Speakon-Speakon from the BQ500 to the NY121P, fine.

But what cable would run from the NY121P to the 1/4” plug on the CMD121P internal speaker?

It doesn’t seem possible to buy a male speakon -> 1/4” socket cable. If anyone knows of one (or even a combination with adaptor and cable!) please can someone suggest it? Ideally with links to a UK shop where I can buy one.

OR - dangerous - can I run a speakon - speakon from the NY121P to the Speakon out on the combo internal head, and leave the captive 1/4” connected? Has anyone tried this?

 

help please.....

Contact http://bassic-bits.co.uk/ , who is @obbm
He can surely make a speakon to female jack cable of high quality.

Interesting idea.  The speakers would be connected correctly in parallel, but I'd worry that the external amp will be sending power into the combo amp, and that something would fry.

I wasn’t really serious about plugging into the socket on the amp... just wondering if anyone had tried it!

 

That amazon cable doesn’t work though - the 1/4” jack end is the wrong gender!

What I really need is one with a Speakon at one end, and a 1/4” SOCKET at the other end.

Anyone got any ideas?

Yes, use a 1/4 socket/socket adaptor.
