Frequently asked questions
Can I use these products together?
No. The CU800 charges wireless transmitters for the DMS800/DMS700 systems. The CM311 is a microphone. They serve completely different functions, though both could theoretically be part of an AKG wireless audio setup if your system includes both transmitters and a head-worn microphone option.
What is the CM311 best suited for?
The CM311 excels in live performance, broadcast, theater, worship, and lecturing. It is not ideal for studio vocals or acoustic instrument recording. Its cardioid pattern and shock mount prioritize voice isolation and rejection of ambient noise in dynamic environments.
How long does CU800 charging take?
The product description does not specify charging time. It notes that the CU800 uses pulse charging technology with automatic current optimization, but exact duration is not provided in the available specifications.
Does the CM311 require phantom power?
Yes, as a condenser microphone, the CM311 requires phantom power. Standard professional audio interfaces and mixing consoles typically provide this. The microphone operates at 75 Ohm impedance with XLR 3-pin female connector.
