Frequently asked questions
Are these products compatible with each other?
No. The C451 B is a wired condenser microphone with XLR output for studio and live recording. The APS4 is RF infrastructure for distributing wireless microphone antenna signals to multiple receivers. They serve completely separate functions.
What skill level do I need for each?
The C451 B suits intermediate to professional recording engineers and live sound technicians familiar with microphone placement and preamp operation. The APS4 is designed for professional wireless system installers and live sound engineers managing multi-receiver setups.
Which one should I buy if I use wireless microphones?
If you want to capture audio from wireless microphones, you still need actual microphones (like the C451 B or a wireless capsule). The APS4 only distributes antenna signals to receivers—it does not replace or eliminate the need for microphones themselves.
Does the C451 B work with wireless systems?
The C451 B is a wired condenser microphone with XLR output, so it does not directly integrate with wireless systems. However, wireless microphone capsules can be paired with separate transmitters for mobility, independent of this antenna distribution equipment.
