Convert your HTDZ (or other mono microphone) to stereo with a DIY cable.
WARNING! I am not a qualified electrician or audio engineer! I cannot guarantee the safety of this DIY cable. I am simply sharing my ideas. DO THIS AT YOUR OWN RISK!
In this video I'm going to show you how to make a high quality custom DIY cable for a total cost of about £6 which will make your mono microphone into a stereo microphone. Well, technically it's dual mono, not stereo. For stereo you need two mics. -But this will still be easier in post and easier to monitor while on the shoot!
