The MSMM connects to a 3.5 mm (1/8″) stereo cable and converts it to a 3.5 mm (1/8″) mm mono cable. All current PocketWizard remote camera cables are sold as stereo cables. When using an older radio like the Plus, Plus II, or the top port of a MultiMAX, the sync port is a mono connection. When you add this adapter to your remote camera cable, it makes the stereo cable compatible with older PocketWizard radios.
With this adapter, you can use a 3.5 mm stereo sync cable in a 3.5 mm miniphone mono sync port.
From: 1/8″ (3.5 mm) mono miniphone male
To: 1/8″ (3.5 mm) stereo miniphone female.
A PTMM adapter can be added to a remote camera cable in place of the MSMM. When switched on, the adapter provides half press function at the camera position and keeps the camera awake constantly. When turned off, the cable will behave like a standard mono cable.
